【JPA报错】
org.springframework.web.util.NestedServletException: Request processing failed;
nested exception is org.springframework.dao.InvalidDataAccessApiUsageException:
org.hibernate.hql.QueryExecutionRequestException: Not supported for DML operations
[delete com.jspxcms.core.domain.CmsProjectMember bean where bean.cmsProjectNew.id in (?1)];
nested exception is java.lang.IllegalStateException: org.hibernate.hql.QueryExecutionRequestException:
Not supported for DML operations [delete com.jspxcms.core.domain.CmsProjectMember bean where bean.cmsProjectNew.id in (?1)] at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:965)
【原因】
类的dao删除方法是@Modifying
@Query("delete CmsProjectMember bean where bean.cmsProjectNew.id in (?1)")
public void deleteByProjectId(Collection<Integer> ids);
修改为：
@Modifying
@Query("delete CmsProjectMember bean where bean.cmsProjectNew.id in (?1)")
public void deleteByProjectId(Collection<Integer> ids);

SpringData 学习（5）—— 使用 @Modifying 注解完成修改操作
以上我们做的都是查询，那要如何实现 修改、删除和添加呢？
可以通过以下两种方式：
（1）通过实现 CrudRepository 接口来完成（以后介绍）；
（2）通过 @Modifying 注解完成修改操作（注意：不支持新增）
我们依然使用 @Query 注解，但是还要附加注解 @Modifying。
@Modifying @Query("update Person set email = :email where lastName =:lastName") void updatePersonEmailByLastName(@Param("lastName")String lastName,@Param("email")String email);- 1

测试方法很简单了，暂时并不粘贴出来，因为后面我们要改的。
