直接上图吧:


jar包:

bubuko.com,布布扣

bubuko.com,布布扣

项目目录一览: 

bubuko.com,布布扣

bubuko.com,布布扣

这里的HelloWeb-servlet,xml 是在WEB-INF 下

HelloController:

package com.cqu.tutorial;

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

@Controller
@RequestMapping("/hello")
public class HelloController {
	@RequestMapping(method=RequestMethod.GET)
	public String printHello(ModelMap model){
		model.addAttribute("message","Hello Spring mvc");
		return "hello";
	}
}

在WEB-INF 下建立web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" 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">
 
    <display-name>Spring MVC Application</display-name>
  
   <servlet>
      <servlet-name>HelloWeb</servlet-name>
      <servlet-class>
         org.springframework.web.servlet.DispatcherServlet
      </servlet-class>
      <load-on-startup>1</load-on-startup>
   </servlet>
   <servlet-mapping>
      <servlet-name>HelloWeb</servlet-name>
      <url-pattern>/</url-pattern>
   </servlet-mapping>
</web-app>

这里要注意<url-pattern> 要是"/“ ,之前我用”*.jsp“ 它会提示找不到mapping的路径

然后在同级目录下建立HelloWeb-servlet.xml  这里的HelloWorld 一定要和web里面的servlet-name对应

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:context="http://www.springframework.org/schema/context"
   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-3.2.xsd
   http://www.springframework.org/schema/context 
   http://www.springframework.org/schema/context/spring-context-3.2.xsd">

   <context:component-scan base-package="com.cqu.tutorial"/>
   <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
      <property name="prefix" value="/WEB-INF/hello/" />
      <property name="suffix" value=".jsp" />
   </bean>

</beans>


最后在WEB-INF 下建一个文件夹 hello ,并且创建hello.jsp文件:

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!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=UTF-8">
<title>Hello Spring MVC</title>
</head>
<body>
<h2>${message}</h2>
</body>
</html>

然后运行,http://localhost:8080/HelloSpring  这样是不会有东西的,自己添加/hello 就可以了:http://localhost:8080/HelloSpring/hello
