Spring中配置和读取多个Properties文件--转  
  
  
public class PropertiesFactoryBeanextends PropertiesLoaderSupportimplements FactoryBean, InitializingBean  
Allows for making a properties file from a classpath location available as Properties instance in a bean factory. Can be used to populate any bean property of type Properties via a bean reference.  
  
  
Supports loading from a properties file and/or setting local properties on this FactoryBean. The created Properties instance will be merged from loaded and local values. If neither a location nor local properties are set, an exception will be thrown on initialization.  
  
  
Can create a singleton or a new object on each request. Default is a singleton.  
  
  
   
  
  
一个系统中通常会存在如下一些以Properties形式存在的配置文件  
  
  
1.数据库配置文件demo-db.properties：

database.url=jdbc:mysql://localhost/smaple  
    database.driver=com.mysql.jdbc.Driver  
    database.user=root  
    database.password=123

2.消息服务配置文件demo-mq.properties:  
  
  
\#congfig of ActiveMQ

mq.java.naming.factory.initial=org.apache.activemq.jndi.ActiveMQInitialContextFactory  
    mq.java.naming.provider.url=failover:(tcp://localhost:61616?soTimeout=30000&connectionTimeout=30000)?jms.useAsyncSend=true&timeout=30000  
    mq.java.naming.security.principal=  
    mq.java.naming.security.credentials=  
    jms.MailNotifyQueue.consumer=5

3.远程调用的配置文件demo-remote.properties：

remote.ip=localhost  
    remote.port=16800  
    remote.serviceName=test

一、系统中需要加载多个Properties配置文件  
  
  
应用场景：Properties配置文件不止一个，需要在系统启动时同时加载多个Properties文件。  
  
  
配置方式：

<?xml version="1.0" encoding="UTF-8"?>  
    <beans xmlns="http://www.springframework.org/schema/beans"  
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
        xsi:schemaLocation="  
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">  
          
          
        <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">  
            <property name="locations">  
               <list>  
                    
                  <value>classpath:/opt/demo/config/demo-db.properties</value>  
                    
                  <value>file:/opt/demo/config/demo-mq.properties</value>  
                  <value>file:/opt/demo/config/demo-remote.properties</value>  
                </list>  
            </property>  
        </bean>  
          
          
        <bean id="MQJndiTemplate" class="org.springframework.jndi.JndiTemplate">  
            <property name="environment">  
                <props>  
                    <prop key="java.naming.factory.initial">${mq.java.naming.factory.initial}</prop>  
                    <prop key="java.naming.provider.url">${mq.java.naming.provider.url}</prop>  
                    <prop key="java.naming.security.principal">${mq.java.naming.security.principal}</prop>  
                    <prop key="java.naming.security.credentials">${mq.java.naming.security.credentials}</prop>  
                    <prop key="userName">${mq.java.naming.security.principal}</prop>  
                    <prop key="password">${mq.java.naming.security.credentials}</prop>  
                </props>  
            </property>  
        </bean>  
    </beans>

我们也可以将配置中的List抽取出来:

<?xml version="1.0" encoding="UTF-8"?>  
    <beans xmlns="http://www.springframework.org/schema/beans"  
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
        xsi:schemaLocation="  
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">  
          
          
        <bean id="propertyResources" class="java.util.ArrayList">  
            <constructor-arg>  
                <list>  
                    
                  <value>classpath:/opt/demo/config/demo-db.properties</value>  
                    
                  <value>file:/opt/demo/config/demo-mq.properties</value>  
                  <value>file:/opt/demo/config/demo-remote.properties</value>  
                </list>  
            </constructor-arg>  
        </bean>  
          
          
        <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">  
            <property name="locations" ref="propertyResources" />  
        </bean>  
          
          
        <bean id="MQJndiTemplate" class="org.springframework.jndi.JndiTemplate">  
            <property name="environment">  
                <props>  
                    <prop key="java.naming.factory.initial">${mq.java.naming.factory.initial}</prop>  
                    <prop key="java.naming.provider.url">${mq.java.naming.provider.url}</prop>  
                    <prop key="java.naming.security.principal">${mq.java.naming.security.principal}</prop>  
                    <prop key="java.naming.security.credentials">${mq.java.naming.security.credentials}</prop>  
                    <prop key="userName">${mq.java.naming.security.principal}</prop>  
                    <prop key="password">${mq.java.naming.security.credentials}</prop>  
                </props>  
            </property>  
        </bean>  
    </beans>

二、整合多工程下的多个分散的Properties  
  
  
应用场景：工程组中有多个配置文件，但是这些配置文件在多个地方使用，所以需要分别加载。  
  
  
配置如下：

<?xml version="1.0" encoding="UTF-8"?>  
    <beans xmlns="http://www.springframework.org/schema/beans"  
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
        xmlns:p="http://www.springframework.org/schema/p"  
        xsi:schemaLocation="  
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">  
          
          
        <bean id="dbResources" class="java.util.ArrayList">  
            <constructor-arg>  
            <list>  
                <value>file:/opt/demo/config/demo-db.properties</value>  
            </list>  
            </constructor-arg>  
        </bean>  
      
          
        <bean id="mqResources" class="java.util.ArrayList">  
            <constructor-arg>  
            <list>  
                <value>file:/opt/demo/config/demo-mq.properties</value>  
            </list>  
            </constructor-arg>  
        </bean>  
          
          
        <bean id="dbPropertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">  
            <property name="order" value="1" />  
            <property name="ignoreUnresolvablePlaceholders" value="true" />   
            <property name="locations" ref="dbResources" />  
        </bean>  
          
          
        <bean id="mqPropertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">  
            <property name="order" value="2" />  
            <property name="ignoreUnresolvablePlaceholders" value="true" />   
            <property name="locations" ref="mqResources" />  
        </bean>  
          
          
        <bean id="rmsDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"   
            p:driverClassName="${demo.db.driver}" p:url="${demo.db.url}" p:username="${demo.db.username}"   
            p:password="${demo.db.password}" pp:maxActive="${demo.db.maxactive}"p:maxWait="${demo.db.maxwait}"   
            p:poolPreparedStatements="true" p:defaultAutoCommit="false">  
        </bean>  
          
          
        <bean id="MQJndiTemplate" class="org.springframework.jndi.JndiTemplate">  
            <property name="environment">  
                <props>  
                    <prop key="java.naming.factory.initial">${mq.java.naming.factory.initial}</prop>  
                    <prop key="java.naming.provider.url">${mq.java.naming.provider.url}</prop>  
                    <prop key="java.naming.security.principal">${mq.java.naming.security.principal}</prop>  
                    <prop key="java.naming.security.credentials">${mq.java.naming.security.credentials}</prop>  
                    <prop key="userName">${mq.java.naming.security.principal}</prop>  
                    <prop key="password">${mq.java.naming.security.credentials}</prop>  
                </props>  
            </property>  
        </bean>  
    </beans>

注意：其中order属性代表其加载顺序，而ignoreUnresolvablePlaceholders为是否忽略不可解析的 Placeholder，如配置了多个PropertyPlaceholderConfigurer，则需设置为true。这里一定需要按照这种方式设置这两个参数。  
  
  
   
  
  
三、Bean中直接注入Properties配置文件中的值  
  
  
应用场景：Bean中需要直接注入Properties配置文件中的值 。例如下面的代码中需要获取上述demo-remote.properties中的值：  
  
  
public class Client() \{    
    private String ip;    
    private String port;    
    private String service;    
\}    
 配置如下：

<?xml version="1.0" encoding="UTF-8"?>  
    <beans xmlns="<a href="http://www.springframework.org/schema/beans">http://www.springframework.org/schema/beans</a>"  
     xmlns:xsi="<a href="http://www.w3.org/2001/XMLSchema-instance">http://www.w3.org/2001/XMLSchema-instance</a>"  
     xmlns:util="<a href="http://www.springframework.org/schema/util">http://www.springframework.org/schema/util</a>"  
     xsi:schemaLocation="  
     <a href="http://www.springframework.org/schema/beans">http://www.springframework.org/schema/beans</a> <a href="http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">http://www.springframework.org/schema/beans/spring-beans-3.0.xsd</a>  
     <a href="http://www.springframework.org/schema/util">http://www.springframework.org/schema/util</a> <a href="http://www.springframework.org/schema/util/spring-util-3.0.xsd">http://www.springframework.org/schema/util/spring-util-3.0.xsd</a>">  
       
       
       
     <util:properties id="remoteSettings" location="file:/opt/demo/config/demo-remote.properties" />   
       
       
     <bean id="settings"   
       class="org.springframework.beans.factory.config.PropertiesFactoryBean">  
       <property name="locations">  
      <list>  
        <value>file:/opt/rms/config/rms-mq.properties</value>  
        <value>file:/opt/rms/config/rms-env.properties</value>  
      </list>  
       </property>  
     </bean>  
    </beans>

Client类中使用Annotation如下：

import org.springframework.beans.factory.annotation.Value;  
      
    public class Client() {  
        @Value("#{remoteSettings['remote.ip']}")  
        private String ip;  
        @Value("#{remoteSettings['remote.port']}")  
        private String port;  
        @Value("#{remoteSettings['remote.serviceName']}")  
        private String service;  
    }

四、Bean中存在Properties类型的类变量  
  
  
应用场景：当Bean中存在Properties类型的类变量需要以注入的方式初始化  
  
  
1. 配置方式：我们可以用（三）中的配置方式，只是代码中注解修改如下

import org.springframework.beans.factory.annotation.Value;  
    import org.springframework.beans.factory.annotation.Autowired;  
      
    public class Client() {  
        @Value("#{remoteSettings}")  
        private Properties remoteSettings;  
    }

2. 配置方式：也可以使用xml中声明Bean并且注入

代码如下：

import org.springframework.beans.factory.annotation.Autowired;  
      
    public class Client() {  
        //@Autowired也可以使用  
        private Properties remoteSettings;  
          
        //getter setter  
    }

上述的各个场景在项目群中特别有用，需要灵活的使用上述各种配置方式。

# [五种方式让你在java中读取properties文件内容不再是难题][java_properties] #

一、背景

最近，在项目开发的过程中，遇到需要在properties文件中定义一些自定义的变量，以供java程序动态的读取，修改变量，不再需要修改代码的问题。就借此机会把Spring+SpringMVC+Mybatis整合开发的项目中通过java程序读取properties文件内容的方式进行了梳理和分析，先和大家共享。

二、项目环境介绍

Spring 4.2.6.RELEASE

SpringMvc 4.2.6.RELEASE

Mybatis 3.2.8

Maven 3.3.9

Jdk 1.7

Idea 15.04

三、五种实现方式

方式1.通过context:property-placeholder加载配置文件jdbc.properties中的内容

<context:property-placeholder location="classpath:jdbc.properties" ignore-unresolvable="true"/>

上面的配置和下面配置等价，是对下面配置的简化

<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
       <property name="ignoreUnresolvablePlaceholders" value="true"/>
       <property name="locations">
          <list>
             <value>classpath:jdbc.properties</value>
          </list>
        </property>
    </bean>

注意：这种方式下，如果你在spring-mvc.xml文件中有如下配置，则一定不能缺少下面的红色部分，关于它的作用以及原理，参见另一篇博客：**[context:component-scan标签的use-default-filters属性的作用以及原理分析][context_component-scan_use-default-filters]**

<context:component-scan base-package="com.hafiz.www" use-default-filters="false">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

方式2.使用注解的方式注入，主要用在java代码中使用注解注入properties文件中相应的value值

<bean id="prop" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
       
       <property name="locations">
           <array>
              <value>classpath:jdbc.properties</value>
           </array>
       </property>
    </bean>

方式3.使用util:properties标签进行暴露properties文件中的内容

<util:properties id="propertiesReader" location="classpath:jdbc.properties"/>

注意：使用上面这行配置，需要在spring-dao.xml文件的头部声明以下红色的部分

方式4.通过PropertyPlaceholderConfigurer在加载上下文的时候暴露properties到自定义子类的属性中以供程序中使用

<bean id="propertyConfigurer" class="com.hafiz.www.util.PropertyConfigurer">
       <property name="ignoreUnresolvablePlaceholders" value="true"/>
       <property name="ignoreResourceNotFound" value="true"/>
       <property name="locations">
           <list>
              <value>classpath:jdbc.properties</value>
           </list>
       </property>
    </bean>

自定义类PropertyConfigurer的声明如下:

package com.hafiz.www.util;
    
    import org.springframework.beans.BeansException;
    import org.springframework.beans.factory.config.ConfigurableListableBeanFactory;
    import org.springframework.beans.factory.config.PropertyPlaceholderConfigurer;
    
    import java.util.Properties;
    
    /**
     * Desc:properties配置文件读取类
     * Created by hafiz.zhang on 2016/9/14.
     */
    public class PropertyConfigurer extends PropertyPlaceholderConfigurer {
    
        private Properties props;       // 存取properties配置文件key-value结果
    
        @Override
        protected void processProperties(ConfigurableListableBeanFactory beanFactoryToProcess, Properties props)
                                throws BeansException {
            super.processProperties(beanFactoryToProcess, props);
            this.props = props;
        }
    
        public String getProperty(String key){
            return this.props.getProperty(key);
        }
    
        public String getProperty(String key, String defaultValue) {
            return this.props.getProperty(key, defaultValue);
        }
    
        public Object setProperty(String key, String value) {
            return this.props.setProperty(key, value);
        }
    }

使用方式：在需要使用的类中使用@Autowired注解注入即可。

方式5.自定义工具类PropertyUtil，并在该类的static静态代码块中读取properties文件内容保存在static属性中以供别的程序使用

package com.hafiz.www.util;
    
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    
    import java.io.*;
    import java.util.Properties;
    
    /**
     * Desc:properties文件获取工具类
     * Created by hafiz.zhang on 2016/9/15.
     */
    public class PropertyUtil {
        private static final Logger logger = LoggerFactory.getLogger(PropertyUtil.class);
        private static Properties props;
        static{
            loadProps();
        }
    
        synchronized static private void loadProps(){
            logger.info("开始加载properties文件内容.......");
            props = new Properties();
            InputStream in = null;
            try {
    　　　　　　　
                in = PropertyUtil.class.getClassLoader().getResourceAsStream("jdbc.properties");
    　　　　　　  
                //in = PropertyUtil.class.getResourceAsStream("/jdbc.properties");
                props.load(in);
            } catch (FileNotFoundException e) {
                logger.error("jdbc.properties文件未找到");
            } catch (IOException e) {
                logger.error("出现IOException");
            } finally {
                try {
                    if(null != in) {
                        in.close();
                    }
                } catch (IOException e) {
                    logger.error("jdbc.properties文件流关闭出现异常");
                }
            }
            logger.info("加载properties文件内容完成...........");
            logger.info("properties文件内容：" + props);
        }
    
        public static String getProperty(String key){
            if(null == props) {
                loadProps();
            }
            return props.getProperty(key);
        }
    
        public static String getProperty(String key, String defaultValue) {
            if(null == props) {
                loadProps();
            }
            return props.getProperty(key, defaultValue);
        }
    }

说明：这样的话，在该类被加载的时候，它就会自动读取指定位置的配置文件内容并保存到静态属性中，高效且方便，一次加载，可多次使用。

四、注意事项及建议

以上五种方式，前三种方式比较死板，而且如果你想在带有@Controller注解的Bean中使用，你需要在SpringMVC的配置文件spring-mvc.xml中进行声明，如果你想在带有@Service、@Respository等非@Controller注解的Bean中进行使用，你需要在Spring的配置文件中spring.xml中进行声明。原因请参见另一篇博客：**[Spring和SpringMVC父子容器关系初窥][Spring_SpringMVC]**

我个人比较建议第四种和第五种配置方式，第五种为最好，它连工具类对象都不需要注入，直接调用静态方法进行获取，而且只一次加载，效率也高。而且前三种方式都不是很灵活，需要修改@Value的键值。

五、测试验证是否可用

1.首先我们创建PropertiesService

package com.hafiz.www.service;
    
    /**
     * Desc:java程序获取properties文件内容的service
     * Created by hafiz.zhang on 2016/9/16.
     */
    public interface PropertiesService {
    
        /**
         * 第一种实现方式获取properties文件中指定key的value
         *
         * @return
         */
        String getProperyByFirstWay();
    
        /**
         * 第二种实现方式获取properties文件中指定key的value
         *
         * @return
         */

2.创建实现类PropertiesServiceImpl

package com.hafiz.www.service.impl;
    
    import com.hafiz.www.service.PropertiesService;
    import com.hafiz.www.util.PropertyConfigurer;
    import com.hafiz.www.util.PropertyUtil;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.stereotype.Service;
    
    /**
     * Desc:java程序获取properties文件内容的service的实现类
     * Created by hafiz.zhang on 2016/9/16.
     */
    @Service
    public class PropertiesServiceImpl implements PropertiesService {
    
        @Value("${test}")
        private String testDataByFirst;
    
        @Value("#{prop.test}")
        private String testDataBySecond;
    
        @Value("#{propertiesReader[test]}")
        private String testDataByThird;
    
        @Autowired
        private PropertyConfigurer pc;
    
        @Override
        public String getProperyByFirstWay() {
            return testDataByFirst;
        }
    
        @Override
        public String getProperyBySecondWay() {
            return testDataBySecond;
        }
    
        @Override
        public String getProperyByThirdWay() {
            return testDataByThird;
        }
    
        @Override
        public String getProperyByFourthWay(String key) {
            return pc.getProperty(key);
        }
    
        @Override
        public String getProperyByFourthWay(String key, String defaultValue) {
            return pc.getProperty(key, defaultValue);
        }
    
        @Override
        public String getProperyByFifthWay(String key) {
            return PropertyUtil.getPropery(key);
        }
    
        @Override
        public String getProperyByFifthWay(String key, String defaultValue) {
            return PropertyUtil.getProperty(key, defaultValue);
        }
    }

3.控制器类PropertyController

package com.hafiz.www.controller;
    
    import com.hafiz.www.service.PropertiesService;
    import com.hafiz.www.util.PropertyUtil;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.PathVariable;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    /**
     * Desc:properties测试控制器
     * Created by hafiz.zhang on 2016/9/16.
     */
    @Controller
    @RequestMapping("/prop")
    public class PropertyController {
        @Autowired
        private PropertiesService ps;
    
        @RequestMapping(value = "/way/first", method = RequestMethod.GET)
        @ResponseBody
        public String getPropertyByFirstWay(){
            return ps.getProperyByFirstWay();
        }
    
        @RequestMapping(value = "/way/second", method = RequestMethod.GET)
        @ResponseBody
        public String getPropertyBySecondWay(){
            return ps.getProperyBySecondWay();
        }
    
        @RequestMapping(value = "/way/third", method = RequestMethod.GET)
        @ResponseBody
        public String getPropertyByThirdWay(){
            return ps.getProperyByThirdWay();
        }
    
        @RequestMapping(value = "/way/fourth/{key}", method = RequestMethod.GET)
        @ResponseBody
        public String getPropertyByFourthWay(@PathVariable("key") String key){
            return ps.getProperyByFourthWay(key, "defaultValue");
        }
    
        @RequestMapping(value = "/way/fifth/{key}", method = RequestMethod.GET)
        @ResponseBody
        public String getPropertyByFifthWay(@PathVariable("key") String key){
            return PropertyUtil.getProperty(key, "defaultValue");
        }
    }
