上一篇是非注解开发的springmvc登录示例，这一篇使用注解开发
环境:
JDK1.8
Tomcat:8.0
win7
操作步骤和上一篇大同小异：
第一步：创建web工程，并把相应的jar导入到'WEB-INF/lib"目录下
工程目录如下：
index.jsp代码：
1 <%@ page language="java" contentType="text/html; charset=UTF-8" 2 pageEncoding="UTF-8"%> 3 <!DOCTYPE html> 4 <html> 5 <head> 6 <meta charset="UTF-8"> 7 <title>com.zgy.index</title> 8 </head> 9 <body> 10 <form action="login.do" > 11 <h1>欢迎来到登录界面</h1> 12 帐号：<input type="text" name="userName"><br><br> 13 密码：<input type="password" name="passWord"><br><br> 14 <input type="submit" name="button" value="登录"> 15 </form> 16 </body> 17 </html>
第二步：配置web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
<display-name>springmvc2</display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>springmvc2</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>springmvc2</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
</web-app>
第三步：配置springmvc2-servlet.xml
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:mvc="http://www.springframework.org/schema/mvc" 4 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" 5 xmlns:context="http://www.springframework.org/schema/context" 6 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd 7 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd 8 http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd 9 http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.2.xsd"> 10 <!-- 注解驱动 --> 11 <mvc:annotation-driven/> 12 13 <!-- springmvc2的扫描驱动 --> 14 <context:component-scan base-package="com.zgy.servlet"></context:component-scan> 15 16 <!-- 试图解析器 --> 17 <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 18 <property name="prefix" value="/jsp/"></property> 19 <property name="suffix" value=".jsp"></property> 20 </bean> 21 22 </beans>
第四步：编写控制器类
1 package com.zgy.servlet; 2 3 import org.springframework.stereotype.Controller; 4 import org.springframework.web.bind.annotation.RequestMapping; 5 6 @Controller 7 public class logincontroller { 8 9 @RequestMapping(value="login.do") 10 public String login() { 11 12 System.out.println("-----用户登录------"); 13 14 return "success"; 15 16 } 17 }
