springmvc登路示例（注解）

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 }
