构建施耐德楼控系统数据库后台服务器示例工程—（工程创建）

比眉伴天荒 2022-08-08 06:38 175阅读 0赞

工作中需要在施耐德楼控系统上添加后台管理功能和手机控制功能，单位采购的施耐德的产品仅仅是用于控制现场设备的楼控模块及上位机编程与HMI，我们需要在此基础上，自主开发手机端控制功能，那么就需要通过建立后台工程用于往施耐德的硬件上发信号或者修改其数据库。

本文即是建立在此想法的基础上，记录一下如何采用Spring、Hibernate、Rest这个框架构建一个可以快速开发的后台管理框架。

1.使用eclipse新建一个普通JAVA工程

2.右键工程名，选择属性，点击"Project Facets"将“Dynamic Web Module勾选上，一个动态Web工程即建好

3.将Spring、Hibernate、Rest所需的jar文件全部复制到Web工程的WEB-INF/lib文件夹下（建议将jar文件复制到工程下面而不是引用，否则还需在tomcat下面放置一份jar包，否则会照成运行时报错）

4.新建Web.xml用于配置Spring信息

<?xml version="1.0" encoding="UTF-8"?>
    
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    
    	xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:javaee="http://java.sun.com/xml/ns/javaee"
    
    	xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    
    	xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
    
    	version="2.4">
    
    	<display-name>TacControlServerWeb</display-name>
    
    	<distributable />
    
    	<context-param>
    
    		<param-name>contextConfigLocation</param-name>
    
    		<param-value>
    
                classpath:/spring/applicationContext*.xml
    
            </param-value>
    
    	</context-param>
    
    	<filter>
    
    		<filter-name>encodingFilter</filter-name>
    
    		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    
    		<init-param>
    
    			<param-name>encoding</param-name>
    
    			<param-value>UTF-8</param-value>
    
    		</init-param>
    
    		<init-param>
    
    			<param-name>forceEncoding</param-name>
    
    			<param-value>true</param-value>
    
    		</init-param>
    
    	</filter>
    
    	<filter-mapping>
    
    		<filter-name>encodingFilter</filter-name>
    
    		<url-pattern>/*</url-pattern>
    
    	</filter-mapping>
    
    	<listener>
    
    		
    
    		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    
    	</listener>
    
    	<listener>
    
    		
    		<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
    
    	</listener>
    
    	<listener>
    
    		
    
    		<listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
    
    	</listener>
    
    
    	
    
    	<servlet>
    		<display-name>JAX-RS REST Servlet</display-name>
    		<servlet-name>JAX-RS REST Servlet</servlet-name>
    		<servlet-class>com.sun.jersey.spi.spring.container.servlet.SpringServlet</servlet-class>
    		<init-param>
    			<param-name>com.sun.jersey.config.property.packages</param-name>
    			<param-value>szx.rest</param-value>
    		</init-param>
    		<load-on-startup>1</load-on-startup>
    	</servlet>
    	<servlet-mapping>
    		<servlet-name>JAX-RS REST Servlet</servlet-name>
    		<url-pattern>/szxrest/*</url-pattern>
    	</servlet-mapping>
    
    	<servlet>

    		<display-name>FindInfo</display-name>
    		<servlet-name>FindInfo</servlet-name>

    	<welcome-file-list>
    		<welcome-file>index.jsp</welcome-file>
    	</welcome-file-list>
    
    </web-app>

5.配置了Spring后，在Spring的配置文件中配置Hibernate信息和自动注入的方式，如下applicationContext-core.xml

<?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:aop="http://www.springframework.org/schema/aop"
    
    	xmlns:context="http://www.springframework.org/schema/context"
    
    	xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx"
    
    	xsi:schemaLocation="http://www.springframework.org/schema/beans
    
    						http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
    
    						http://www.springframework.org/schema/aop
    
    						http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
    
    						http://www.springframework.org/schema/context
    
    						http://www.springframework.org/schema/context/spring-context-2.5.xsd
    
    						http://www.springframework.org/schema/jee
    
    						http://www.springframework.org/schema/jee/spring-jee-2.5.xsd
    
    						http://www.springframework.org/schema/tx
    
    						http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
    
    	<context:property-placeholder location="classpath:jdbc.properties" />
    
    	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
    		destroy-method="close">
    
    		<property name="driverClassName" value="${jdbc.driverClassName}" />
    		<property name="url" value="${jdbc.url}" />
    		<property name="username" value="${jdbc.username}" />
    		<property name="password" value="${jdbc.password}" />
    		<property name="maxActive" value="2000" />
    		<property name="maxIdle" value="1000"></property>
    		<property name="maxWait" value="25000" />
    		<property name="poolPreparedStatements" value="false" />
    		<property name="defaultAutoCommit" value="true" />
    
    	</bean>
    
    	
    	<bean id="sessionFactory"
    		class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    		<property name="dataSource" ref="dataSource" />
    		<property name="packagesToScan">
    			<list>
    				<value>szx</value>
    			</list>
    		</property>
    		<property name="hibernateProperties">
    			<value>
    				hibernate.dialect=${hibernate.dialect}
    				hibernate.query.substitutions=true 'Y', false 'N'
    				hibernate.cache.use_second_level_cache=true
    				hibernate.cache.provider_class=org.hibernate.cache.EhCacheProvider
    				hibernate.jdbc.fetch_size=50
    				hibernate.jdbc.batch_size=25
    				hibernate.show_sql=true
    				hibernate.format_sql=false
    				hibernate.use_sql_comments=true
    			</value>
    		</property>
    		<property name="lobHandler" ref="lobHandler" />
    	</bean>
    
    	<bean id="lobHandler" class="org.springframework.jdbc.support.lob.OracleLobHandler">
    		<property name="nativeJdbcExtractor" ref="nativeJdbcExtractor" />
    	</bean>
    
    	<bean id="nativeJdbcExtractor"
    		class="org.springframework.jdbc.support.nativejdbc.CommonsDbcpNativeJdbcExtractor" />
    
    	
    	<bean id="transactionManager"
    		class="org.springframework.orm.hibernate3.HibernateTransactionManager">
    		<property name="sessionFactory" ref="sessionFactory" />
    	</bean>
    
    	
    	<context:annotation-config />
    
    	
    	<context:component-scan base-package="szx" name-generator="szx.core.spring.CustomBeanNameGenerator"/>
    
    	
    	<aop:aspectj-autoproxy />
    
    	
    	<tx:annotation-driven />
    
    	<aop:config>
    		<aop:advisor advice-ref="txAdvice"
    			pointcut="execution(* *..service.*Manager.*(..))" order="100" />
    	</aop:config>
    
    	<tx:advice id="txAdvice">
    		<tx:attributes>
    			<tx:method name="*" rollback-for="Throwable" />
    		</tx:attributes>
    	</tx:advice>
    
    </beans>

6.新建jdbc.properties文件，配置数据库连接（数据库可以适配MySQL、Oracle、SqlServer）

#hibernate.dialect=cn.walle.core.support.hibernate.Oracle10gDialect
    hibernate.dialect=org.hibernate.dialect.SQLServerDialect
    #jdbc.driverClassName=oracle.jdbc.driver.OracleDriver
    #jdbc.driverClassName=com.microsoft.jdbc.sqlserver.SQLServerDriver
    #jdbc.url=jdbc:sqlserver://localhost:1433;integratedSecurity=true;DatabaseName=taclogdata
    jdbc.driverClassName=net.sourceforge.jtds.jdbc.Driver
    jdbc.url=jdbc:jtds:sqlserver://localhost:1433;integratedSecurity=true;DatabaseName=taclogdata
    #jdbc.url=jdbc:oracle:thin:@192.168.103.9:1521:orcl
    #jdbc.url=jdbc:oracle:thin:@219.237.193.91:1521:orcl
    #jdbc.url=jdbc:oracle:thin:@iwmds.rdh.com:1521:orcl
    jdbc.username=tacvista
    jdbc.password=tacvista

7.工程结构如下图
