MyBatis 3.2.6插入时候获取自增主键方法
MyBatis 3.2.6插入时候获取自增主键方法有二
以MySQL5.5为例:
方法1:
<insert id="insert" parameterType="Person" useGeneratedKeys="true" keyProperty="id">
insert into person(name,pswd) values(#{name},#{pswd})
</insert>
方法2:
<insert id="insert" parameterType="Person">
<selectKey keyProperty="id" resultType="long">
select LAST_INSERT_ID()
</selectKey>
insert into person(name,pswd) values(#{name},#{pswd})
</insert>
插入前实体id属性为0;
插入后实体id属性为保存后自增的id;
