未调用 Spring Boot @RepositoryEventHandler

问题描述

我已经设置了一个 @RepositoryEventHandler 并且由于某些未知原因没有被调用.

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);
}

还有我的主班:

@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);
    }
}

提前感谢您的帮助，我只是找不到错误.

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

推荐答案

可能会发生一些事情.

你的 repo 没有用 @RestResource 注释，但我猜这只是一个疏忽.

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，并且您正在通过单元测试进行测试，入口点未通过 REST API.handlers 只捕获通过该向量的 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.

如果你想捕获任何 repo 事件，不管入口点，那么你想使用 AbstractRepositoryEventListener

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

Spring Data Rest Events 文档 涵盖了这一点.另请参阅在 spring boot 中侦听存储库事件.

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