Spring autowire 不适用于安全配置

Question

我得到一个异常java.lang.IllegalArgumentException: Not an entity Error。我已经浏览了我的代码，我认为我有所有正确的注释。我正在使用 shiro 进行身份验证，并在运行时引发错误。这以前有效，但我现在不明白这些问题。

这是我的 pojo 课：

 @Entity
 @Table(name ="message") 
 public class Message implements Serializable{  
     ...
 } 

这是我的仓库：

@Repository
@Component(value = "messageRepository")
public interface MessageRepository extends JpaRepository<User, Long> {
    ...
}

我的网络安全配置片段，它引发了错误

<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager" depends-on="messageRepository">
    <property name="realm" ref="myRealm" />
</bean>

这是错误：

感谢您的帮助。

如果您使用的是 JPA，那么您必须将您的实体添加到您的 persistence.xml 中的persistence-unit 标签下。

例子

<persistence-unit name="persistance-unit" transaction-type="RESOURCE_LOCAL">
  ....
  <class>com.mycompany.messages.model.Message</class>
  ....
</persistence-unit>

您正在注解应该注解实现类的接口，@Repository 和 @Component 也只是冗余使用 @Repository("messageRepository")。

@Repository("messageRepository")
public class MessageRepositoryImpl implements MessageRepository {
    ...
    //Implement the interface methods
}
