TK mybatis SelectByPrimaryKey異常

今天在使用TK mybatis 插件時出現了一個奇怪的現象，當我調用selectByPrimaryKey(7)時，mybatis的sql日誌打印爲以下所示

===> Preparing SELECT id,a, b, c  FROM test WEHER id =? and a = ? and b = ? and c=?

===> Parameters: 7(Long),7(Long),7(Long),7(Long),7(Long)

 

 

 

 而後我百度查了類似問題，

發現是PO類裏沒有給主鍵添加javax.persistence.@ID註解致使的

添加完後的sql打印爲：

 

 

 

 

===> Preparing SELECT id,a, b, c  FROM test WEHER id =?

===> Parameters: 7(Long)
