spring MVC開發步驟

1. 把spring3提供的jar包拷貝到/WEB-INF/lib/目錄下
2. 在web.xml中進行spring3mvc的啟動配置
   web.xml放在/WEB-INF/目錄下
   配置模版：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" 
xmlns="http://java.sun.com/xml/ns/j2ee" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

配置spring MVC的核心Servlet控制器
<servlet>
  <servlet-name>spring</servlet-name>
   <servletclass>
    org.springframework.web.servlet.DispatcherServlet
   </servlet-class>
   <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
  <servlet-name>spring</servlet-name>
  <url-pattern>*.do</url-pattern>
</servlet-mapping>


</web-app>

3. 創建servlet-name-servlet.xml的Action映射文件
   說明：
   1）該文件應放在/WEB-INF/目錄下
   2）servlet-name應為web.xml文件中的<servlet-name>標簽值,本例為spring-servlet.xml
   配置模版為：

<?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:p="http://www.springframework.org/schema/p"     
        xmlns:context="http://www.springframework.org/schema/context"     
   xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd   
       http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd   
       http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd   
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

</beans> 

配置action 采用spring mvc注解的方式把請求映射為相應的action對象中的方法來處理
 <!-- 啟用spring mvc 注解 -->
<context:annotation-config />
<!-- 設置使用注解的類所在的jar包 -->
<context:component-scan base-package="com.zte"></context:component-scan>
<!-- 完成請求和注解POJO的映射 -->
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />
<!-- 對轉向頁面的路徑解析。prefix：前綴， suffix：后綴 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
 <property name="prefix" value="/WEB-INF/page/" />            
     <property name="suffix" value=".jsp" />
     </bean> 

4. 編寫spring MVC Action程序

package com.zte.action;
 
@Controller  //類似Struts的Action
public class TestController {
@Resource(name = "loginService") 
private LoginService loginService;   
@RequestMapping("/login.do")
public String regLogin(User user) {
System.out.println("HelloController.handleRequest()");
loginService.add(user); 
 return "success";} 
}
