本文是我在学习网络视频SpringMVC的过程中写下的。感谢发布视频的各位前辈
下面讲解SpringMVC注解启用的几个关键步骤：
首先需要加载配置文件（如果使用本人的代码请自己定义路径）
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
<display-name>springMVC1</display-name>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
<!-- springMVC 入口 dispatcher -->
<servlet>
<servlet-name>springMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 加载配置文件路径 -->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:config/springAnnotation-servlet.xml</param-value>
</init-param>
<!-- 何时启动 大于0的值表示容器启动时初始化此servlet，正值越小优先级越高-->
<load-on-startup>1</load-on-startup>
</servlet>
<!-- 拦截 -->
<servlet-mapping>
<servlet-name>springMVC</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
<?xml version="1.0" encoding="UTF-8"?>

<!-- spring 启动时扫描包 -->
<context:component-scan base-package="com.tgb.web.controller.annotation">
</context:component-scan>
<!-- 开启注解 -->
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />
<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"></bean>
<!-- 路径对应调用的Controller -->
<bean name="/test/helloworld" class="com.tgb.web.controller.HelloWorldController"/>
<!-- 视图解析 -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp"></property>
<property name="suffix" value=".jsp"></property>
</bean>
<!-- 静态资源访问（不拦截此目录下的东西的访问） -->
<mvc:resources location="/img/" mapping="/img/**" />
</beans>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.POST)
public ModelAndView addUser(){
String result = "addUser";
return new ModelAndView("/annotation","result",result);
}
@RequestMapping(value="/user/delUser",method=RequestMethod.GET)
public ModelAndView delUser(){
String result = "delUser";
return new ModelAndView("/annotation","result",result);
}
@RequestMapping(value="/user/toUser",method=RequestMethod.GET)
public ModelAndView toUser(){
String result = "toUser";
return new ModelAndView("/touser","result",result);
}
}
此处请注意，@Controller的使用。@RequestMapping(value="/user/addUser",method=RequestMethod.POST)中的value表示跳转路径，method表示通过哪种方式调用这个方法
最后是前台的jsp界面
annotation.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
