导入c3p0jar包
在这里插入图片描述
创建bean包，里面创建实体类

import lombok.Data;
/**
 * Create Time: 2019.03.13 16:38
 *
 * @author 徐海翔
 **/
@Data
public class User {
    private Integer uid;
    private String username;
    private String password;
    private String rename1;
    private String nameId;

    public User() {
    }

    public User(String username, String password, String rename1, String nameId) {
        this.username = username;
        this.password = password;
        this.rename1 = rename1;
        this.nameId = nameId;
    }
}

建立Dao层，创建Dao接口和mapper文件

public interface UserDao {
    public void add(User user);
}

<?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.zhiyou100.Dao.UserDao">
    <insert id="add" parameterType="User">
       insert into user values (null,#{username},#{password},#{rename1},#{nameId})
    </insert>
</mapper>

第一步：创建配置文件applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<!-- 约束文件 -->
<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:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"

       xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-4.0.xsd
            http://www.springframework.org/schema/tx
            http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
    		 http://www.springframework.org/schema/aop
     		http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
           ">
    <!-- spring配置 -->
    <!--
		一个bean就是一个被spring容器管理的类   管理他的生命周期 IOC
			class  就是被spring管理的类
			id是bean的标志  id必须唯一  id的值一般情况下是类名的首字母小写
	 -->
    <!--识别注解-->
    <context:annotation-config></context:annotation-config>
    <!--注解扫描,需要修改-->
    <context:component-scan base-package="com.zhiyou100"></context:component-scan>
    <!--自动为spring容器中那些配置@aspectJ切面的bean创建代理-->
    <aop:aspectj-autoproxy></aop:aspectj-autoproxy>
    <!--需要修改-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="com.mysql.cj.jdbc.Driver"></property>
        <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/njdf?serverTimezone=Asia/Shanghai&amp;characterEncoding=UTF-8&amp;useSSL=false"></property>
        <property name="user" value="root"></property>
        <property name="password" value="cqrjxk39"></property>
    </bean>
    <!--在spring中配置SqlsessionFactoryBean-->
    <bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
        <property name="mapperLocations" value="classpath:com/zhiyou100/Dao/*.xml"></property>
        <property name="configLocation" value="classpath:mybatis-cfg.xml"></property>
    </bean>
    <!--Spring配置mapper-->
    <bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.zhiyou100.Dao"></property>
        <property name="sqlSessionFactoryBeanName" value="sessionFactory"></property>
    </bean>
</beans>

第二步：创建service层

创建service接口

public interface UserService {
    public void add(User user);
}

实现接口

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service("userServiceImpl")
public class UserServiceImpl implements UserService {
    @Autowired
    private UserDao userDao;
    @Override
    public void add(User user) {
        this.userDao.add(user);
    }
}

Test测试类

public void test1(){
       ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
       UserService userServiceImpl = context.getBean("userServiceImpl",UserService.class);
       User user = new User("嘻嘻", "2132", "12312", "12312");
       userServiceImpl.add(user);
       context.close();
   }
