我得到以下错误
原因:org.springframework.beans.NotWritablePropertyException:bean类的无效属性'packagesToScan'[org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean]:Bean属性'packagesToScan'不可写或具有无效的setter方法。setter的参数类型是否与getter的返回类型匹配?\
我用的是spring3.2,依赖项是用MAven添加的。一切似乎都没问题。为什么我会得到这个错误。这是我的文件

谢谢
查看Spring 3.2.3源代码,我注意到实际上在组织.Spring框架.orm.jpa.本地容器实体管理器工厂豆
方法中没有获取包ToScan()
,所以,豆类实用程序
是正确的启动这个例外!
我已经解决了这个问题。事实上,我认为我的POM是不正确的。我正在做spring MVC项目,首先我的POM如下。我认为使用这个POM我有太多的jar冲突,因为maven使用传递方法来下载jar。

不知道你的包裹ToScan?希望您使用注释,如@Table、@Entity、@column…
,您不需要扫描任何包。当您尝试对一个实体进行crud时,hibernate将读取注释我的答案是删除该行
更新config.dao.xml
