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