Why is the first Query working and the second not? (Spring application JPA)
问题
我有两个查询，我想在一个Spring项目中使用它们（使用JPA）。第一个查询可以获取一个账户，这个功能正常。对于第二个查询，我希望能够更新数据库中的 'disabled' 字段。代码如下：
// 这是第一个查询（正常工作）
@Query(value = "SELECT * FROM accounts WHERE email = ?1", nativeQuery = true)
Account findByEmailAddress(String emailAddress);
// 这是第二个查询（不工作）
@Modifying
@Query(value = "UPDATE accounts SET disabled = 1 WHERE email= ?1 ", nativeQuery = true)
int disableAccountByEmail(String emailAddress);
我在某个地方读到需要添加 @Modifying，这将返回一个 int 或 void。但是当我尝试测试它是否工作时，我得到一个 TransactionRequiredException 错误，错误信息是：执行了一个更新/删除 查询。

I have two Query's that I want to use in a Spring project (using JPA). The first one gets an account and this works correctly. For the second one I want it to be able to update the 'disabled' field in the database. The codes look like this:
// This is the first Query (works correctly)
@Query(value = "SELECT * FROM accounts WHERE email = ?1", nativeQuery = true)
Account findByEmailAddress(String emailAddress);
// This is the second Query (doesn't work)
@Modifying
@Query(value = "UPDATE accounts SET disabled = 1 WHERE email= ?1 ", nativeQuery = true)
int disableAccountByEmail(String emailAddress);
I did read somewhere I needed to add @Modifying and this will return an int or void. But when I try to test if it works I get a TransactionRequiredException error that says: Executing an update/delete query

得分: 2
尝试使用以下内容进行更新查询：
@Transactional
@Modifying(clearAutomatically = true)
英文:
Try using the below for update query
@Transactional
@Modifying(clearAutomatically = true)
