java - 如何使用JPA运行“SET SQL_SAFE_UPDATES = 0”之类的查询

我希望在我的Spring桌面应用程序中运行此查询

SET SQL_SAFE_UPDATES = 0;

应该是GET请求还是PUT请求？我都尝试过但没有成功。
目前我正在尝试

@GetMapping("/orderbook/safeMode")
    private void setSafeMode() {
        orderBookRepository.setSafeMode();
    }

@Query(value = "SET SQL_SAFE_UPDATES = 0;", nativeQuery = true)
    void setSafeMode();

但是它给出了一个错误

2019-10-18 11:38:37.844 ERROR 12112 --- [nio-8080-exec-2] o.h.engine.jdbc.spi.SqlExceptionHelper   : ResultSet is from UPDATE. No Data.
2019-10-18 11:38:37.851 ERROR 12112 --- [nio-8080-exec-2] o.a.c.c.C.[.[.[/].[dispatcherServlet]    : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.orm.jpa.JpaSystemException: could not execute query; nested exception is org.hibernate.exception.GenericJDBCException: could not execute query] with root cause

java.sql.SQLException: ResultSet is from UPDATE. No Data.

任何建议请

最佳答案

它通过向存储库方法添加@Modifying和@Transactional批注来工作

@Modifying
@Transactional
@Query(value = "SET SQL_SAFE_UPDATES = 0;", nativeQuery = true)
void setSafeMode();

感谢Nikolay Shevchenko建议@Modifying注释
