Unknown entity:
在网上找到的大多数的解决办法都是导包<em>问题</em>和mapping配置<em>问题</em>两种,但是并不合适 最终解决的办法是因为自己的hibernate版本是5.2,在创建sessionfactory 时使用了 //Configuration config = new Configuration().configure();         //ServiceRegistry serviceRegistry = n

Adding @EntityScan( basePackages = {&quot;com.prithvi.thoughtprocess.beans&quot;} to your Application class. That is needed for hibernate to scan your entities.
错误:org.springframework.orm.jpa.JpaSystemException: could not deserialize;
这个是如果你用的是<em>JPA</em>操作数据库,在两张表进行关联时,要加上注解@ManyToOne,并且该类要实现序列化。
关于SSH异常unknown entity
看到许多解决方案,大致都是一样的。1、import javax.persistence.Entity;注解@<em>entity</em>导包应该导这个。2、没加入映射文件。我的是Spring整合了hibernate所以没有hibernate的cfg文件。而是包扫描,扫描的路径写错也会导致这个异常。...
