這種不帶引數查詢的時候，它會建立一個payformation物件，而這個物件Id預設為0；而在建立的物件它的id就有值了，然後進行查詢

       WHERE

             1=1

            ID=0

這樣查詢出來的就不是全部的，只是查ID=0的。並且如果是按引數查詢不按id查詢，他也會對ID進行設定，比如：

    WHERE

             1=1

      AND custmerId = 12341278L

      AND ID = 0L

      依然會帶著id=0,上面說的是按customerId進行查詢，同樣對id也進行了設定,這就會出現問題。

解決辦法，統一在Mapper中加一句判斷語句。

<if test="@[email protected](metalId) and metalId != 0"> AND ID  =#{id} </if>
