(1)新建javaEE web项目

 

 (2)加入相关依赖的坐标

数据访问:mybatis, mysql, junit, druid, 

spring框架: spring-context, spring-jdbc, spring-aop

 (3) 创建相应的包和类

package com.ffyc.ssm.dao;

import com.ffyc.ssm.model.Admin;
import org.springframework.stereotype.Repository;

@Repository
public interface LoginDao {


    public Admin login(Admin admin);
}

package com.ffyc.ssm.model;

public class Admin {
    private int id;
    private String account;
    private String password;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getAccount() {
        return account;
    }

    public void setAccount(String account) {
        this.account = account;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

package com.ffyc.ssm.service;

import com.ffyc.ssm.dao.LoginDao;
import com.ffyc.ssm.model.Admin;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

@Transactional
@Service(value = "loginService")
public class LoginService {

    @Autowired
    LoginDao loginDao;
    public Admin login(Admin admin){
       Admin a = loginDao.login(admin);
        return a;
    }
}

<?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.ffyc.ssm.dao.LoginDao">


    <select id="login" resultType="com.ffyc.ssm.model.Admin">
        select * from admin where account = #{account} and password = #{password}
    </select>
</mapper>

(4) 配置spring和mybatis的配置文件

在resources中建mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<!--
这是mybatis核心配置文件
-->

    <settings>
         <!--启用日志功能,在运行时,可以将实际执行的sql细节打印到控制台-->
        <setting name="logImpl" value="STDOUT_LOGGING"/>
        <setting name="mapUnderscoreToCamelCase" value="true"/>
    </settings>

    <!-- 配置类型简称   -->
    <typeAliases>
    <!-- <typeAlias type="com.ffyc.mybatispro.model.Admin" alias="Admin"></typeAlias>-->
    <package name="com.ffyc.ssm.model"/>
    </typeAliases>



</configuration>

在 resources中建spring.xml

<?xml version="1.0" encoding="UTF-8"?>

    <aop:aspectj-autoproxy />
    <!--  导入数据库连接,以及事务管理配置   -->
    <import resource="classpath:db.xml"></import>

</beans>

在 resources中建db.xml

<?xml version="1.0" encoding="UTF-8"?>

在 resources中建config.propertis

classDriverName=com.mysql.cj.jdbc.Driver
url=jdbc:mysql://127.0.0.1:3306/ssmdb?serverTimezone=Asia/Shanghai
uname=root

集成mybatis配置 ,导入mybatis-spring  的jar包   

Spring 结合 mybatis 插件包

在 resources中建spring-mybatis.xml

<?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="sqlSessionFactoryBeanName" value="sqlSessionFactory">
        </property>

</beans>

 搭建完成后测试一下

package com.ffyc.ssm.test;

import com.ffyc.ssm.model.Admin;
import com.ffyc.ssm.service.LoginService;
import org.junit.Test;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Test1 {
    @Test
    public void test(){
        ClassPathXmlApplicationContext app = new ClassPathXmlApplicationContext("spring.xml");
        LoginService loginService = app.getBean("loginService", LoginService.class);
        Admin admin = new Admin();
        admin.setAccount("xiaosi");
        admin.setPassword("999");
        Admin login = loginService.login(admin);
        System.out.println(login);
    }
}

测试结果:
