我有一個使用spring，hibernate和JPA的web應用程序。當我想運行我的DAO的單元測試，我得到以下錯誤：使用名稱'entityManagerFactory'創建bean時出錯
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [application-common-context.xml]: Invocation of init method failed; nested exception is java.lang.NullPointerException
應用共context.xml中：
