基于注解Spring MVC 3.0簡單示例

首先說明一下使用的版本：

JDK：1.6   Tomcat：6.0   Spring：3.2，使用到的Jar包截圖：

工程結構截圖：

接下來：web.xml文件配置：

<?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"

</web-app>

log4j.properties文件配置：

log4j.rootLogger=WARN,stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender

log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

log4j.appender.stdout.layout.ConversionPattern=%n%-d{yyyy-MM-dd HH\:mm\:ss}%n[%p]-[Thread\: %t]-[%C.%M()]\: %m%n

SpringMVC-servlet.xml文件的配置：

<?xml version="1.0" encoding="UTF-8"?>
<beans default-lazy-init="true"
       xmlns="http://www.springframework.org/schema/beans"  
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:tx=""       
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
       xmlns:context=
       xmlns:mvc=
       xsi:schemaLocation= 
"                        http://www.springframework.org/schema/context/spring-context-3.1.xsd">
 
    <!-- 注解驅動 -->
    <mvc:annotation-driven />
    <!-- 掃描包 -->
    <context:component-scan base-package="com.project.controller" />
 <!-- ViewResolver -->
 <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
     <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
     <property name="prefix" value="/WEB-INF/jsp/"/>
     <property name="suffix" value=".jsp"/>
 </bean>
 <!-- HandlerAdapter -->
 <!-- <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
  <property name="mappings">
   <props>
    <prop key="/index">Hello</prop>
   </props>
  </property>
 </bean> -->
 <!-- HandlerMapping -->
 <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/>
 <!-- HandlerMapping -->
 <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/>
 <!-- <bean name="/index" class="com.project.controller.HelloController"/> -->
 <!-- <bean id="Hello" class="com.project.controller.HelloController" /> -->
</beans>

HelloController代碼內容：

package com.project.controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
@RequestMapping("/hello")
public class HelloController {
 @RequestMapping("/index")
 public ModelAndView index(HttpServletRequest request,HttpServletResponse response) throws Exception {
  ModelAndView modelView = new ModelAndView();
  modelView.addObject("msg","Hello Index");
  modelView.setViewName("index");
  System.err.println("執行index！");
  return modelView;
 }
 @RequestMapping("/show")
 public ModelAndView show(HttpServletRequest request,HttpServletResponse response) throws Exception {
  ModelAndView modelView = new ModelAndView();
  modelView.addObject("msg","Hello show");
  modelView.setViewName("index");
  System.err.println("執行show！");
  return modelView;
 }
}

OK，運行效果如圖：
