[英]add custom method to Spring Data JPA

问题描述

I have created a repository for my entity and I added two methods to it as following : 我为我的实体创建了一个存储库，并向其中添加了两种方法，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 entity : 犯罪实体： 

@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
}

and this is my service class : 这是我的服务班级： 

@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
}

but when I call offreRepository.remove I'm getting this error message : 但是当我调用offreRepository.remove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

How can I solve this problem ? 我怎么解决这个问题 ？

Please make sure that following things are correct at your end. 请确保以下操作在您的末端是正确的。

  • Your @Modifying annotation should be wrapped up with @Transactional attribute which helps post-processor wraps @Transactional annotated bean methods with an AOP method interceptor which handles transactional behavior. 您的@Modifying注释应使用@Transactional属性进行包装，该属性可帮助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。

example 例 

    @Modifying
    @Transactional
    @Query("UPDATE Offre o SET o.state = 'DISABLED' where o.codeOffre=:x")
    void disable(@Param("x") Long offre);
  • Also make sure entries for context:component-scan and <tx:annotation-driven /> declared at application level (in application context. 还要确保在应用程序级别（在应用程序上下文中）声明了context：component-scan和<tx:annotation-driven />条目。
