我们直接切人正题，不多逼逼赖赖
第一步：依赖，一下的这些基本上是SSM整合的全部依赖

第二步：com.ssm.entity层
public class Smbms_User implements Serializable {
private Integer id;
private String usercode;
private String username;
private String userpassword;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getUsercode() {
return usercode;
}
public void setUsercode(String usercode) {
this.usercode = usercode == null ? null : usercode.trim();
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username == null ? null : username.trim();
}
public String getUserpassword() {
return userpassword;
}
public void setUserpassword(String userpassword) {
this.userpassword = userpassword == null ? null : userpassword.trim();
}
}
第三步：com.ssm.dao层
@Repository
public interface Smbms_UserMapper { @Select("select * from smbms_user where userCode=#{user_code} and userPassword=#{user_password}")
public Smbms_User login(@Param("user_code") String user_code, @Param("user_password") String user_password); }
第四步：com.ssm.dao层中的.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.ssm.dao.Smbms_UserMapper" >
<resultMap id="BaseResultMap" type="com.ssm.entity.Smbms_User" >
<id column="id" property="id" jdbcType="BIGINT" />
<result column="userCode" property="usercode" jdbcType="VARCHAR" />
<result column="userName" property="username" jdbcType="VARCHAR" />
<result column="userPassword" property="userpassword" jdbcType="VARCHAR" />
<result column="gender" property="gender" jdbcType="INTEGER" />
<result column="birthday" property="birthday" jdbcType="DATE" />
<result column="phone" property="phone" jdbcType="VARCHAR" />
<result column="address" property="address" jdbcType="VARCHAR" />
<result column="userRole" property="userrole" jdbcType="INTEGER" />
<result column="createdBy" property="createdby" jdbcType="BIGINT" />
<result column="creationDate" property="creationdate" jdbcType="TIMESTAMP" />
<result column="modifyBy" property="modifyby" jdbcType="BIGINT" />
<result column="modifyDate" property="modifydate" jdbcType="TIMESTAMP" />
</resultMap>
</mapper>
第五步：com.ssm.service层
public interface Smbms_UserService {
public Smbms_User login(String user_code, String user_password);
}
第六步：com.ssm.service.impl层
@Service("smbms_UserService")
public class Smbms_UserServcieImpl implements Smbms_UserService {
//植入Dao层对象
@Resource
private Smbms_UserMapper smbms_userMapper;
//事务
/* @Transactional(isolation=Isolation.DEFAULT)*/
@Override
public Smbms_User login(String user_code, String user_password) {
return smbms_userMapper.login(user_code,user_password);
}
}
第七步：com.ssm.controller层
@Controller
@RequestMapping("/user")
public class Smbms_UserController {
//植入Service层分对象
@Resource
private Smbms_UserService smbms_userService; @RequestMapping("/login")
public String doLogin(Smbms_User smbms_user, HttpSession session){
Smbms_User user = smbms_userService.login(smbms_user.getUsercode(), smbms_user.getUserpassword());
if(user!=null){
session.setAttribute("user",user);
return "welcome";
}
return "login";
}
}
第八步：resourdes中的mybatis-config.xml文件
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<!--根节点-->
<configuration> <settings>
<!--log4j配置引入-->
<setting name="logImpl" value="LOG4J"/> </settings> <!--设置别名-->
<typeAliases>
<!--全局设置别名:默认以类名作为别名-->
<package name="com.ssm.entity"/>
</typeAliases> <!--mappers 代表小配置集合-->
<mappers>
<!--<mapper resource="org/mybatis/example/BlogMapper.xml"/>-->
<package name="com.ssm.dao"/>
</mappers> </configuration>
第九步：resourdes中的jdbc.properties文件
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/test?useUniCode=true&characterEncoding=utf-8
jdbc.username=root
jdbc.password=root
第十步：resourdes中的applicationContext.xml文件
<?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:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
<!--扫描注解-->
<context:component-scan base-package="com.ssm"/>
<!--添加MVC支持-->
<mvc:annotation-driven/>
<!--配置视图解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/"/>
<property name="suffix" value=".jsp"/>
</bean>
<!--释放静态资源-->
<mvc:default-servlet-handler/>
<!--加载配置文件-->
<context:property-placeholder location="classpath:jdbc.properties"/>
<!--配置数据源-->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
<property name="driverClassName" value="${jdbc.driver}"/>
<property name="url" value="${jdbc.url}"/>
<property name="username" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
</bean>
<!--SqlSessionFactory-->
<bean class="org.mybatis.spring.SqlSessionFactoryBean">
<!--加载数据源-->
<property name="dataSource" ref="dataSource"/>
<!--加载Mybatis配置文件-->
<property name="configLocation" value="classpath:mybatis-config.xml"/>
</bean>
<!--扫描Dao层-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.ssm.dao"/>
</bean>
<!--开启事务注解支持-->
<tx:annotation-driven/>
<!--事务管理器-->
<bean class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>
</beans>
第十一步：WEB-INF下的web.xml文件
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" > <web-app>
<display-name>Archetype Created Web Application</display-name>
<filter>
<filter-name>characterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<!--初始化参数-->
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-</param-value>
</init-param>
<!--强制使用UTF-8编码-->
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>characterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!--中央调度器-->
<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:applicationContext.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>
第十二步：登录页面的搭建
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>登陆</title>
</head>
<body>
<div>
<form action="/user/login" method="post">
用户名：<input type="text" name="usercode"/>
密码：<input type="password" name="userpassword"/>
<input type="submit" value="登陆"/>
</form>
</div>
</body>
</html>
登录成功的页面
<%@ page contentType="text/html;charset=UTF-8" language="java" isELIgnored="false" %>
<html>
<head>
<title>欢迎</title>
</head>
<body>
欢迎光临：${user.username}
</body>
</html>
以上都是对SSM整合的讲解，具体顺序可以自己搭配，希望对大家有帮助，如果有什么看不懂的地方，可以评论，我一定会第一时间帮助大家解答疑惑，谢谢
