如何用Spring建立MVC模式

web.xml配置

<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>/WEB-INF/spring-mvc.xml,
    /WEB-INF/spring-mvc-servlet.xml</param-value>
</context-param>
<!—servlet-name必须和context-param指定的xml相同 -->
<servlet>
  <servlet-name>spring-mvc</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
  <servlet-name>spring-mvc</servlet-name>
  <url-pattern>*.do</url-pattern>
</servlet-mapping>
<listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

spring-mvc.xml配置

<bean id="handlerMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
  <property name="mappings">
    <props>
      <prop key="bulletinList.do">bulletionListAction</prop>
      <prop key="hello.do">helloWorldController</prop>
    </props>
  </property>
</bean>
<bean id="bulletionListAction" class="com.controller.BulletionListAction"></bean>
<bean id="helloWorldController" class="com.test.HelloWorldController"></bean>

spring-mvc-servlet.xml配置

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
  <property name="viewClass">
    <value>org.springframework.web.servlet.view.JstlView</value>
  </property>
</bean>

BulletionListAction.java配置

public class BulletionListAction implements Controller{
  public ModelAndView handleRequest(HttpServletRequest request,
        HttpServletResponse response) throws Exception {
    System.out.println("BulletionListAction执行成功");
    return new ModelAndView("index.jsp");
  }
}
