如何使用JPA查询将数据插入数据库？

java sql spring-data-jpa spring-boot

我对我准备好的陈述有问题，但我无法弄清楚错误在哪里。我正在尝试将URI链接插入到数据库中。

 @Repository
 public interface LoggerDao extends CrudRepository<Logger, Long> {
 @Query("select t from Logger t where t.user.id=?#{principal.id}")
 List<Logger> findAll();

@Modifying
@Query(value = "insert into Logger t (t.redirect, t.user.id) VALUES (:insertLink,?#{principal.id})", nativeQuery = true)
@Transactional
void logURI(@Param("insertLink") String insertLink);

错误

我设法解决了这个问题。我在参数中添加了一个id，以便我可以在控制器中使用主体传入用户的id。

@Repository
public interface LoggerDao extends CrudRepository<Logger, Long> {
    @Query("select t from Logger t where t.user.id=?#{principal.id}")
    List<Logger> findAll();

    @Modifying
    @Query(value = "insert into Logger (redirect,user_id) VALUES (:insertLink,:id)", nativeQuery = true)
    @Transactional
    void logURI(@Param("insertLink") String insertLink, @Param("id") Long id);

有一种方法可以使用obj（非本机）查询（使用@Query和@Modifying）进行插入，但这取决于您使用的数据库。下面在Oracle中为我工作（使用双表）：

@Repository
public interface DualRepository extends JpaRepository<Dual,Long> {
    @Modifying
    @Query("insert into Person (id,name,age) select :id,:name,:age from Dual")
    public int modifyingQueryInsertPerson(@Param("id")Long id, @Param("name")String name, @Param("age")Integer age);
}
