直接上图吧：
jar包：
项目目录一览：
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
