分析、処理:
私のbeanクラスに対して、その属性タイプはinteger、string、charタイプを含んで、最も愚かな方法で1つずつ削除して検査して、前の2つはすべて大丈夫で、一時停止します;
beanクラスを見てみると、charという2つのタイプの属性が含まれていて、彼らが問題を起こしたのではないでしょうか.(先の開発では、charタイプに設定されていて、アクセスが正常で間違いがなかったことがありますが、この上は考えていません)
2つのプロパティを削除した後、ok、問題点を見つけます.しかし、他のbeanはどうして大丈夫ですか?このbeanに対応するテーブルデータは人為的に作られており、charタイプのフィールドには値が設定されていないものがありますが、これと関係がありますか?
Updateのすべてのcharフィールドに値があり、通過します.
Ft、これは私を1時間やった.
