@RepositoryEventHandler事件以@RepositoryRestController停止

@RepositoryEventHandler事件以@RepositoryRestController停止

它 已实现 。:-)

在

@RepositoryRestController

实现中定义的方法替换了发布事件的默认RepositoryEntityController中的方法

@RepositoryEventHandler

。

但是添加这些事件使其

@RepositoryRestControll

成为

ApplicationEventPublisherAware

实现并像默认

RepositoryEntityController

实现一样发布事件很容易：

@Slf4j@RepositoryRestController@AllArgConstructorpublic class AccountRespositoryRestController     implements ApplicationEventPublisherAware {    private final AccountRepository repository;    private ApplicationEventPublisher publisher;    @Override    public void setApplicationEventPublisher(        ApplicationEventPublisher publisher) {        this.publisher = publisher;    }    @RequestMapping(method = RequestMethod.POST,value = "/accounts")    public @ResponseBody PersistentEntityResource post(        @RequestBody Account account,        PersistentEntityResourceAssembler assembler) {        // ...        publisher.publishEvent(new BeforeCreateEvent(account));        Account entity = this.repository.save(account);        publisher.publishEvent(new AfterCreateEvent(entity));        return assembler.toResource(entity);    }}

您也可以在不上课的情况下注入发布者

ApplicationEventPublisherAware

：

@Slf4j@RepositoryRestController@AllArgConstructorpublic class AccountRespositoryRestController {    private final AccountRepository repository;    private final ApplicationEventPublisher publisher;    @RequestMapping(method = RequestMethod.POST,value = "/accounts")    public @ResponseBody PersistentEntityResource post(        @RequestBody Account account,        PersistentEntityResourceAssembler assembler) {        // ...        publisher.publishEvent(new BeforeCreateEvent(account));        Account entity = this.repository.save(account);        publisher.publishEvent(new AfterCreateEvent(entity));        return assembler.toResource(entity);    }}
