如何解決BeanCreationExceptrion錯誤？

[英]how to solve BeanCreationExceptrion error?

 原文  2015-09-07 07:12:33  5   1    java/ spring/ junit

問題描述

我嘗試使用spring4和jackrabbit開發一些服務器程序。 當我使用JUnit測試Controller類時，發生BeanCreationExceptrion錯誤。 我認為此錯誤與自動裝配變量相關。 幫我。 如何解決這個問題呢？

這是我的Controller類的負責人。

為了讓Spring在您的測試案例中自動裝配SoremoreController字段，它需要在ApplicationContext中為該類型的bean定義一個bean。 這意味着您需要對在ContextConfiguration批注中指出的xml文件中定義了SoremoreController的包（或父包）進行組件掃描。

請注意，SoremoreController實例中的所有自動裝配字段也必須在ApplicationContext中定義相應的bean，否則Spring將無法創建該實例，從而導致測試失敗，並且堆棧跟蹤類似於您發布的跟蹤（但始終明確指出-朝向最后-問題的根本原因）。
