在spring-boot中侦听存储库事件 [英] Listening repository events in spring-boot

问题描述

我正在尝试RepositoryEventListener在spring-boot应用程序中工作，但我想我做错了...

I am trying RepositoryEventListener to work in spring-boot application but i guess im doing something wrong ...

这是监听器中的代码

@SuppressWarnings("rawtypes")
public class BeforeSaveEventListener extends AbstractRepositoryEventListener {  

    @Override
    public void onBeforeSave(Object customer) {
        throw new RuntimeException("++++ BEFORE SAVE EVENT ++++");
    }
}

这是我的申请类

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication springApplication = new SpringApplication(Application.class);
        springApplication.addListeners(new BeforeSaveEventListener());
        springApplication.run(args);
    }
}

在保存操作中，我可以看到这些事件被触发：

On save operation i can see these events fired:

Current Event is org.springframework.data.rest.core.event.BeforeCreateEvent received!
Current Event is org.springframework.data.rest.core.event.AfterCreateEvent received!
Current Event is org.springframework.web.context.support.ServletRequestHandledEvent received!

所以没有看到BeforeSave事件......可能是文档或spring-boot上不赞成的东西机制可能有所不同？

So no "BeforeSave" event seen ... maybe is something deprecated on documentation, or spring-boot mechanisms may be different?

推荐答案

如此处所述 Spring-Data-Rest Validator

......似乎只有之前/之后的保存事件在PUT和PATCH上触发。当发布时，前面/后面的创建事件触发。

" ... it appears that the before/after "save" events only fire on PUT and PATCH. When POSTing, the before/after "create" events fire."
