1. 环境准备
Spring , Spring Data, JPA, HIbernate, JDK 1.7
2. 问题提出
在使用Spring Data 来更新数据之时，爆出了如下错误信息：
@Query("UPDATE User u SET u.state = ?1 WHERE u.server.id = ?2")public void updateAllUsers(long state, long serverid);
错误信息如下：
org.springframework.dao.InvalidDataAccessApiUsageException: org.hibernate.hql.internal.QueryExecutionRequestException: Not supported for DML operations [ update OrderEntity entity set entity.order_status = :status where entity.id = :orderId]; nested exception is java.lang.IllegalStateException: org.hibernate.hql.internal.QueryExecutionRequestException: Not supported for DML

从错误信息中，可以发现，@Query无法进行DML操作，，该如何做呢？
4. 问题解决
@Modifying@Query("UPDATE User u SET u.state = ?1 WHERE u.server.id = ?2")public void updateAllUsers(long state, long serverid);
用最少的悔恨面对过去
