## 一、准备工作 ##

*  安装并配置Java运行环境
 *  Oracle数据库的安装与配置
 *  安装并配置Tomcat
 *  配置Maven环境
 *  创建Maven web-app项目

## 二、项目结构 ##

## 三、导包 ##

因为使用Maven管理项目，所以jar无需手动导入包，只需在pom.xml中配置即可。

**pom.xml配置文件如下**

<?xml version="1.0" encoding="UTF-8"?>

                </resource>
            </resources>
        </build>
    </project>

## 四、SpringMVC配置 ##

**spring-mvc.xml配置文件如下**

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
           xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
           xmlns:mvc="http://www.springframework.org/schema/mvc" 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
          http://www.springframework.org/schema/context
          http://www.springframework.org/schema/context/spring-context-3.1.xsd
          http://www.springframework.org/schema/mvc
          http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
    
        
        <context:component-scan base-package="cn.demo.controller" />
    
        
        <mvc:annotation-driven/>
    
        
        <bean id="viewResolver"
              class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            
            <property name="prefix" value="/WEB-INF/jsp/"></property>
            
            <property name="suffix" value=".jsp"></property>
        </bean>
    
        
        <mvc:resources mapping="/statics/**" location="/statics/"/>
    </beans>

**在web.xml中完善springmvc配置**

**测试SpringMVC配置：TestController**

package cn.demo.controller;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    
    @Controller
    public class TestController {
    
        @RequestMapping(value="/index",method= RequestMethod.GET)
        public String index(){
            return "index";	//返回实际视图，路径在springmvc配置文件中已配置完成
        }
    }

**浏览器输入URL：**

http://localhost:8080/SSHDemo/index

**index.jsp页面如下**

<html>
    <body>
    <h2>Hello World!</h2>
    </body>
    </html>

**运行结果**

--------------------

## 五、Spring+Spring MVC整合 ##

**applicationContext.xml**

**完善web.xml如下**

<?xml version="1.0" encoding="UTF-8"?>
    <web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
        http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
    
      
      <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
          <param-name>contextConfigLocation</param-name>
          
          <param-value>classpath:spring-mvc.xml</param-value>
        </init-param>
        
        <load-on-startup>1</load-on-startup>
      </servlet>
      <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
      </servlet-mapping>
    
    
      
      <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
      </context-param>
    
    
      
      <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
      </listener>
    
    
      
      <filter>
        <description></description>
        <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>
    
    </web-app>

**Spring+Spring MVC配置完成，进行测试**

package cn.demo.service;
    import org.springframework.stereotype.Service;
    
    @Service
    public class TestServiceImpl implements TestService{
    
        @Override
        public String test1(){
            return "index";
        }
    }

**注意 ：类上面的标注@Service注解**

package cn.demo.controller;
    
    import cn.demo.service.TestService;
    import cn.demo.service.TestServiceImpl;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    
    @Controller
    public class TestController {
    
        @Autowired
        private TestService testService;
    
        @RequestMapping(value = "/testService",method =RequestMethod.GET)
        public String main(){
            return testService.test1();
        }
    
    }

**浏览器输入URL：**

http://localhost:8080/SSHDemo/testService

**运行结果**

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MzA5NDM2MQ_size_16_color_FFFFFF_t_70 2]

--------------------

## 六、Spring+SpringMVC+Hibernate整合 ##

**完善applicationContext.xml文件，配置dataSource、sessionFactory等**

完整applicationContext.xml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"

        </bean>
    
        
        <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
            <property name="dataSource" ref="dataSource" />
    
            <property name="hibernateProperties">
                <props>
                 	
                    <prop key="hibernate.hbm2ddl.auto">update</prop>
                    
                    <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop>
                    
                    <prop key="hibernate.show_sql">true</prop>

                    <prop key="hibernate.connection.autocommit">true</prop>
                </props>
            </property>
            
            <property name="packagesToScan" value="cn.demo.pojo"/>
        </bean>
    
    
        
        <context:component-scan base-package="cn.demo">
            
            <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
        </context:component-scan>
    
        
        <bean name="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">

        </bean>
    
        <tx:annotation-driven transaction-manager="transactionManager" />
    </beans>

**完整web.xml如下**

**完整spring-mvc配置文件如下**

**所有配置已经完成，进行测试**

Dept.java实体类
