java - 将自定义方法添加到 Spring Data JPA

Question

我已经为我的实体创建了一个存储库，并向其中添加了两个方法，如下所示:

@Modifying
    @Query("UPDATE Offre o SET o.state = 'DISABLED' where o.codeOffre=:x")
    void disable(@Param("x") Long offre);

    @Modifying
    @Query("UPDATE Offre o SET o.state = 'REMOVED' where o.codeOffre=:x")
    void remove(@Param("x") Long offre);

Offre实体:

@Entity
public class Offre implements Serializable {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "CODE_OFFRE")
    private Long codeOffre;
    private String titre;

    @Enumerated(EnumType.STRING)
    @Column(columnDefinition = "ENUM('ENABLED', 'DISABLED', 'REMOVED') DEFAULT 'ENABLED'")
    private State state;
    //Getters,Setters
}

这是我的服务类别:

@Service
public class OffreMetierImpl implements IOffreMetier {

    @Autowired
    private OffreRepository offreRepository;

    @Override
    @Modifying
    public boolean removeOffre(Long codeOffre) {
        offreRepository.remove(codeOffre);
        return true;
    }

    @Override
    @Modifying
    public boolean disableOffre(Long codeOffre) {
        offreRepository.disable(codeOffre);
        return true;
    }

        // Other methods
}

但是当我调用 offreRepository.remove 时，我收到此错误消息:

failed; nested exception is org.springframework.dao.InvalidDataAccessApiUsageException: Executing an update/delete query; nested exception is javax.persistence.TransactionRequiredException: Executing an update/delete query] with root cause javax.persistence.TransactionRequiredException: Executing an update/delete query

如何解决这个问题？

Answer 1

请确保以下内容正确无误。

• 您的 @Modifying 注释应该用 @Transactional 属性包装，这有助于后处理器使用处理事务行为的 AOP 方法拦截器包装 @Transactional 注释的 bean 方法。

示例

    @Modifying
    @Transactional
    @Query("UPDATE Offre o SET o.state = 'DISABLED' where o.codeOffre=:x")
    void disable(@Param("x") Long offre);

• 还要确保 context:component-scan 的条目和 <tx:annotation-driven />在应用程序级别声明(在应用程序上下文中。
