hibernate映射问题

错误的关键部分:

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

错误原因:

在one-to-many注解配置: @OneToMany (mappedBy = “Articles”),mappedBy指向的是要关联的属性,而不是要关联的类,如果这样配置,hibernate则会找com.wangzhe.model.Keyword类下面的Articles 属性。但实际上没有这个属性,就会报上面的异常

解决方法:

指定到实际关联的属性:即:@OneToMany (mappedBy = “articles “)
