使用mybatis逆向工程生产的代码返回主键信息

 <insert id="insert" parameterType="com.biye.pojo.TbContentCategory" >
    **<selectKey keyProperty="id" resultType="long" order="AFTER">
    	SELECT LAST_INSERT_ID()
    </selectKey>**
    insert into tb_content_category (id, parent_id, name, 
      status, sort_order, is_parent, 
      created, updated)
    values (#{id,jdbcType=BIGINT}, #{parentId,jdbcType=BIGINT}, #{name,jdbcType=VARCHAR}, 
      #{status,jdbcType=INTEGER}, #{sortOrder,jdbcType=INTEGER}, #{isParent,jdbcType=BIT}, 
      #{created,jdbcType=TIMESTAMP}, #{updated,jdbcType=TIMESTAMP})
  </insert>
