Spring Boot @RepositoryEventHandler未调用

问题描述

我已经设置了@RepositoryEventHandler，并且由于某些未知原因而没有调用它.

I've got a @RepositoryEventHandler set up and it is not being invoked for some unknown reason.

@Component
@RepositoryEventHandler(User.class)
public class UserEventHandler {

    @Autowired
    private PasswordCrypto passwordCrypto;

    @HandleBeforeSave
    public void handleUserSave(User user) {
        if (user.getPassword() != null && !"".equals(user.getPassword())) {
            user.setPassword(passwordCrypto.encrypt(user.getPassword()));
        }
    }

    @HandleBeforeCreate
    public void handleUserCreate(User user) {
        user.setPassword(passwordCrypto.encrypt(user.getPassword()));
    }
}

存储库:

public interface UserRepository extends CrudRepository<User, Long> {
    Optional<User> findOneByUsername(String username);
}

我的主要班级:

@SpringBootApplication
@EntityScan("de.ihrig.feuerwehr.hydranet.model")
@EnableJpaRepositories
@ComponentScan({
    "somepath",
    "somepath including the UserEventHandler"
})
public class ServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(ServerApplication.class, args);
    }
}

感谢您的提前帮助，我只是找不到错误.

Thanks for your help in advance, I just cannot find the error.

推荐答案

可能有几件事发生.

您的回购未带有/c1的批注，但我想那只是一个疏忽.

You're repo isn't annotated w/ @RestResource, but I'm guess that was just an oversight.

我猜这些评论是正确的，您正在通过单元测试来测试它，而入口点没有通过REST API. handlers仅捕获通过该向量传来的Repo事件.

I'm guessing the comments are correct and you're testing this through a unit test with an entry point that is not going through the REST API. The handlers only capture Repo events that are coming through that vector.

如果您想捕获任何回购事件，无论进入点是什么，那么您都想使用AbstractRepositoryEventListener

If you want to capture any repo event, regardless of entry point, then you want to use a AbstractRepositoryEventListener

Spring Data Rest事件文档涵盖了这一点.另请参见在春季启动中监听存储库事件.

The Spring Data Rest Events documentation covers this. Also see listening for repository events in spring boot.
