1、JPA Error : The entity has no primary key attribute defined----https://stackoverflow.com/questions/13190997/jpa-error-the-entity-has-no-primary-key-attribute-defined

 

 

The entity has no primary key attribute defined 
實體沒有定義主鍵屬性

初步解決辦法: 
Windows->Persistence->Java Persistence->JPA->Errors/Warnings->Type,將選項Entity has no primary key設為警告或更低的提示級別。(錯誤提示變成了警告提示,治標不治本)

Referenced file contains errors (,,,,,,,,,,,,,,,,,,,). For more information, right click on the message in the Problems View and select “Show Details…”

將 Preferences > XML > XML Files > Validation中”Honour all XML schema locations”前的對號去掉。禁用指向不同schema位置相同名稱空間引用的驗證,僅以第一次找到的可驗證的XML檔案為結果。
