SpringMVC搭建

目录结构:

web.xml;

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
    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_2_5.xsd">
  
    
    
    <servlet>
        <servlet-name>DispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring_mvc/spring_app.xml</param-value>
        </init-param>
              <load-on-startup>1</load-on-startup>
    </servlet>  
    <servlet-mapping>

        <url-pattern>*.action</url-pattern>
    </servlet-mapping>
    
</web-app>    

 

 

spring_app.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans 
      xmlns="http://www.springframework.org/schema/beans"
      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/spring-context-3.0.xsd    
      ">
    <context:component-scan base-package="spring_mvc" />

</beans>

 

 

控制层:HelloAction.java

package spring_mvc;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

//@Controller注解解析的时候看作控制器
@Controller
public class HelloAction {

    public HelloAction(){
        System.out.println("---------------------"+this.hashCode());
    }
    //hello.action的请求都交给都交由次方法处理
    @RequestMapping(value="/hello.action")
    public String Hello() throws Exception{
        System.out.println("后台输出");
        return "success.jsp";
    }
    
}

jap界面:

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
    欢迎 啊,老不死的
</body>
</html>

访问方式:

其中hello.action即是@RequestMapping(value="/hello.action")中value的值,return返回的值即是返回的页面
