1. 新建web project
2. 添加jar
3. 改写web.xml, 注意spring-servlet.xml的名字
<?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"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
<display-name></display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>springMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:config/springAnnotation-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springMVC</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
4. 写 springAnnotation-servlet.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"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
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
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
<!-- 注解扫描包 -->
<context:component-scan base-package="com.tgb.web.controller.annotation" />
<!-- 开启注解 -->
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"></bean>
<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"></bean>
<!-- 静态资源访问 -->
<mvc:resources location="/img/" mapping="/img/**"/>
<mvc:resources location="/js/" mapping="/js/**"/>
<mvc:resources location="/css/" mapping="/css/**"/>
<!-- ViewResolver 视图解析器 -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
</beans>
5. 新建包 com.tgb.web.controller.annotation, 新建类userController.java
注意加注解的方式, 类注解和方法注解
package com.tgb.web.controller.annotation;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class UserController {
@RequestMapping(value="/user/addUser", method=RequestMethod.GET)
public ModelAndView addUser(){
String result = "this is addUser---------";
return new ModelAndView("/annotation","result",result);
}
@RequestMapping(value="/user/delUser", method=RequestMethod.GET)
public ModelAndView delUser(){
String result = "this is delUser---------";
return new ModelAndView("/annotation","result",result);
}
}
6. 根据spring-servlet.xml设置, 在/WEB-INF/jsp/下新建 annotation.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>My JSP ‘annotation.jsp‘ starting page</title>
</head>
<body>
<h> annotation 注解1 </h> <br>
<div>
${result }
</div>
</body>
</html>
7. IE端访问:
http://localhost:8080/springMVC3/user/addUser
显示结果:
annotation 注解1 this is addUser---------
