mybatis配置:


mybatis-config.xml

<configuration>

    <environments default="development">
        <!-- id必须唯一 -->
        <environment id="development">
            <!-- 事务管理器,这里直接使用jdbc的事务管理能力 -->
            <transactionManager type="jdbc" />
            <!-- 数据源配置 -->
            <dataSource type="POOLED">

StudentMapper.xml

<?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">

    <!--useGeneratedKeys="true"表明使用数据库自动生成的主键,
      keyColumn="id"指定Student表中主键列,keyProperty="id"
            表明当插入记录后,会把数据库生成的主键值设置到Student对象
            的id属性中,也就是说,它指定与Student表中的主键列对应的
      Student实体类中的属性是id这个属性-->
    <insert id="add" useGeneratedKeys="true" keyColumn="id"
        keyProperty="id" 
        parameterType="com.abc.domain.Student">
        insert into student(name, gender, major, grade)
        values(#{name}, #{gender}, #{major}, #{grade})
    </insert> 
 
</mapper>
