mybatis Insert, UPDATE operation return primary key

How do I get PK after operation of inserts, update in MyBatis?

Two different ways

1. <insert id= "Insert" parametertype= "User" keyproperty= "id" usegeneratedkeys= "true" >

Java code calls insert (User u) U.GETPK () has a value

2. not recommended , tested, in the spring transaction environment, always return 1, because after the insert, the transaction did not commit so ... Oh, hang on.

<insert id= "Insert" parametertype= "Com.wsmall.kalemao.dal.auth.dataobject.UserDo" >
  <selectkey Resulttype= "Java.lang.Long" keyproperty= "id" order= "after" >
    SELECT last_insert_id ()
  </selectKey>
  INSERT INTO User ...
</insert >

Java Code PK = insert (User u)
