mappedBy reference an unknown target entity property解決方法 - langtianya－IT工程師數位筆記本

文章出處

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'articleDaoImpl': Injection of resource methods failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [applicationContext.xml]: Invocation of init method failed; nested exception is org.hibernate.AnnotationException: mappedBy reference an unknown target entity property: com.wangzhe.model.Keyword.Articles in com.wangzhe.model.Article.keywords

上面是錯誤的關鍵部分

  錯誤原因：在one-to-many注解配置： @OneToMany (mappedBy = "Articles"),mappedBy指向的是要關聯的屬性，而不是要關聯的類，
        如果這樣配置，hibernate則會找com.wangzhe.model.Keyword類下面的Articles 屬性。但實際上沒有這個屬性，就會報上面的異常
   方法：指定到實際關聯的屬性：即：@OneToMany (mappedBy = "articles ")
