1、使用自增主鍵策略獲取新增后的ID值

<insert id="addEmp" parameterType="com.mi.pojo.Employee"useGeneratedKeys="true" keyProperty="id">insert into employee (last_name,gender) values (#{lastName},#{gender})</insert> <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapperPUBLIC "-//mybatis.org//DTD Mapper 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <!--指定為接口的全類名--> <mapper namespace="com.mi.dao.EmployeeMapper"><!--id 為接口的方法名--><select id="getEmployeeById" resultType="com.mi.pojo.Employee">select * from employee where id = #{id}</select><insert id="addEmp" parameterType="com.mi.pojo.Employee"useGeneratedKeys="true" keyProperty="id">insert into employee (last_name,gender) values (#{lastName},#{gender})</insert><delete id="deleteEmp">delete from employee where id = #{id}</delete><update id="updateEmp" >update employee set last_name = #{lastName},gender = #{gender} where id = #{id}</update> </mapper>
