[Record] mybatis obtain data just inserted into the database id

 

　　Sometimes we need mybatis get id after insert, available in two solutions

 

Option One:

<selectKey keyProperty="id" order="AFTER" resultType="java.lang.Integer">
      SELECT LAST_INSERT_ID()
    </selectKey>

　　

Option II:

 <insert id="insert" parameterType="com.xxx" useGeneratedKeys="true" keyProperty="id">

　　

Again, AFTER BEFORE must be uppercase
