springMVC+Hibernate+jpa整合（2）

最后一步添加springMVC

1. 首先加入springweb文件下的两个包
   springMVC
   
   JSON支持
   

2. 配置web.xml

     
           <display-name></display-name>   
       <!-- load spring context -->
       <context-param>
           <param-name>contextConfigLocation</param-name>
           <param-value>classpath:spring/applicationContext.xml</param-value>
       </context-param>
   
       <listener>
           <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
       </listener>
       <!-- end -->
   
       <!-- encodeing filter -->
       <filter>
           <filter-name>encoding-filter</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>
       </filter>
   
       <filter-mapping>
           <filter-name>encoding-filter</filter-name>
           <url-pattern>/*</url-pattern>
       </filter-mapping>
       <!-- end -->
   
       <!-- spring mvc -->
       <servlet>
           <servlet-name>springMVC</servlet-name>
           <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
   
           <!-- 配置springMVC配置文件的路径 -->
           <init-param>
                   <param-name>contextConfigLocation</param-name>
                   <param-value>classpath*:springMVC/spring-servlet.xml</param-value>
           </init-param>
   
           <!-- 配置springMVC在tomcat启动时启动 -->
           <load-on-startup>1</load-on-startup>
       </servlet>
       <servlet-mapping>
           <servlet-name>springMVC</servlet-name>
           <url-pattern>/</url-pattern>
       </servlet-mapping>
       <!-- end -->
   
     <welcome-file-list>
       <welcome-file>index.jsp</welcome-file>
     </welcome-file-list>
   </web-app>
   

3. 配置spring-servlet.xml

           <!-- 注解驱动器 -->
       <mvc:annotation-driven/>
   
       <!-- 注解扫描器 -->
       <context:component-scan base-package="com.wyk.sh4.controller"/>
   
   
       <!-- 静态文件过滤 -->
       <mvc:resources location="/img/" mapping="/img/**"/>  
   
       <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
           <property name="prefix" value="/"></property>
           <property name="suffix" value=".jsp"></property>
       </bean>
   

4. 添加Controller

   @Controller
   @RequestMapping("/test")
   public class HelloController { 
       @RequestMapping("/helloWorld")
       public String helloWorld(){
           return "helloworld";
       }
   }
