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

    <https://img.qb5200.com/download-x/dependency>

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.orghttps://img.qb5200.com/download-x/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.orghttps://img.qb5200.com/download-x/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"

        <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.comhttps://img.qb5200.com/download-x/dtd/web-app_2_3.dtd" >

<web-app>
  <display-name>Archetype Created Web Application<https://img.qb5200.com/download-x/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-8</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
