第一步：新建一个Maven工程；

第二步：加载pom.xml文件

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</project>

\--------------------------------------------------------------------------------

第三步：写log4j.properties，spring-mvc.xml，spring-mybatis.xml文件

\--------------------------------------------------------------------------------

log4j.properties文件如下：

log4j.rootLogger=INFO,Console,File  
log4j.appender.Console=org.apache.log4j.ConsoleAppender  
log4j.appender.Console.Target=System.out  
log4j.appender.Console.layout = org.apache.log4j.PatternLayout  
log4j.appender.Console.layout.ConversionPattern=\[%c\] - %m%n  
log4j.appender.File = org.apache.log4j.RollingFileAppender  
log4j.appender.File.File = logs/ssm.log  
log4j.appender.File.MaxFileSize = 10MB  
log4j.appender.File.Threshold = ALL  
log4j.appender.File.layout = org.apache.log4j.PatternLayout

log4j.appender.File.layout.ConversionPattern =\[%p\] \[%d\{yyyy-MM-dd HH\\:mm\\:ss\}\]\[%c\]%m%n

\--------------------------------

spring-mvc.xml文件如下：

\--------------------------------

<?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"

<mvc:annotation-driven/>  
  
  
<context:component-scan base-package="com.vv.\*" />  
  
  
<bean id="mappingJacksonHttpMessageConverter"  
class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">  
<property name="supportedMediaTypes">

<property name="maxUploadSize" value="10485760000" />  
  
<property name="maxInMemorySize" value="40960" />  
</bean>

</beans>

\--------------------------------

spring-mybatis.xml文件如下：

\--------------------------------

<bean id="transactionManager"  
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">  
<property name="dataSource" ref="jdbcDataSource" />  
</bean>

</beans>

\--------------------------------

第四步：写web.xml文件

\--------------------------------

<?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" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app\_3\_0.xsd" id="WebApp\_ID" version="3.0">

</servlet>  
<servlet-mapping>  
<servlet-name>springmvc</servlet-name>  
<url-pattern>/</url-pattern>  
</servlet-mapping>

</web-app>

\----------------------------------

第五步：写index.jsp文件

\-----------------------------------

<%@ page language="java" import="java.util.\*" pageEncoding="utf-8"%>  
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>  
<%  
String path = request.getContextPath();  
String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort()  
\+ path + "/";  
%>  
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">  
<html>  
<head>  
<base href="<%=basePath%>">

<meta charset="utf-8">  
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">

用户名：<input type="text" name="username" id="username" /><br>  
密码：<input type="password" name="password" id="password" /><br>  
<input type="submit" name="提交" />  
<input type="reset" name="重置" />  
</form>  
</body>

</html>

\----------------------------------------

第六步：写控制器

\---------------------------------------

package com.vv.controller;  
import javax.servlet.http.HttpSession;  
import org.springframework.beans.factory.annotation.Autowired;  
import org.springframework.stereotype.Controller;  
import org.springframework.web.bind.annotation.RequestMapping;  
import org.springframework.web.bind.annotation.RequestMethod;  
import org.springframework.web.bind.annotation.RequestParam;  
import com.vv.dao.UserDao;  
import com.vv.pojo.User;  
@Controller

public class UserController \{

//自动注入后，就有了dao接口的对象了。

@Autowired  
UserDao userdao;  
@RequestMapping(value = "/login", method = RequestMethod.POST)  
public String getuser(@RequestParam("id") int id,  
@RequestParam("username") String username,  
@RequestParam("password") String password,  
HttpSession session) \{ //这里把session写在参数里是明智的  
User user=new User();  
user.setId(id);  
user.setUsername(username);  
user.setPassword(password);  
System.out.println(user.toString());  
session.setAttribute("user", user);  
user=userdao.getUser(id);  
System.out.println(user.toString());  
return "user/dispuser";  
\}

\----------------------------

第七步：写dao接口

\---------------------------

package com.vv.dao;  
import com.vv.pojo.User;  
public interface UserDao \{  
public User getUser(int uid);

\---------------------------

第八步：写UserMapper.xml文件

\--------------------------------

<?xml version="1.0" encoding="UTF-8"?>  
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">  
  
<mapper namespace="com.vv.dao.UserDao">  
<select id="getUser" parameterType="java.lang.Integer" resultType="com.vv.pojo.User">  
select \* from xs\_user where id=\#\{id\}  
</select>  
</mapper>
