java.lang.NoClassDefFoundError: com/pb/entity/TUser
阿新 • • 發佈：2018-11-02
maven專案，jdk1.7、tomcat7
maven結構bos-parent下面有幾個maven module.bos-entity
解決一半：bos-entity中匯入了實體類。需要右擊bos-parent → maven → update project，重新啟動只剩下一個錯誤了

好奇怪的異常
解決：web.xml中有一處擴大session的作用範圍的操作使用的是：org.springframework.orm.hibernate5.support.OpenSessionInViewFilter
直接從檔案中複製的所以該類寫錯了。導致了型別轉換錯誤。
