我正在尝试RepositoryEventListener在春季启动应用程序中工作,但我想我做错了什么...

这是侦听器中的代码

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

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


这是我的应用程序类

@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,我可以看到触发了以下事件:

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!


因此,没有看到“ BeforeSave”事件……也许是文档中不推荐使用的东西,或者spring-boot机制可能有所不同?

最佳答案

如此处所述Spring-Data-Rest Validator

“……看来,“保存”之前/之后的事件仅在PUT和PATCH上触发。发布时,“创建”之前/之后的事件才触发。”
