Spring Data Rest：未调用RepositoryEventHandler方法 [英] Spring Data Rest: RepositoryEventHandler methods not invoked
问题描述
我正在尝试添加RepositoryEventHandler，如 Spring数据库REST文档到REST存储库，如下所示：
I am trying to add a RepositoryEventHandler as described on Spring Data REST documentation to the REST repository shown below:
@RepositoryRestResource(collectionResourceRel = "agents", path = "/agents")
public interface AgentRepository extends CrudRepository<Agent, Long> {
// no implementation required; Spring Data will create a concrete Repository
}
我创建了一个AgentEventHandler：
I created an AgentEventHandler:
@Component
@RepositoryEventHandler(Agent.class)
public class AgentEventHandler {
/**
* Called before {@link Agent} is persisted
*
* @param agent
*/
@HandleBeforeSave
public void handleBeforeSave(Agent agent) {
System.out.println("Saving Agent " + agent.toString());
}
}
并在@Configuration中声明它组件：
and declared it in a @Configuration component:
@Configuration
public class RepositoryConfiguration {
/**
* Declare an instance of the {@link AgentEventHandler}
*
* @return
*/
@Bean
AgentEventHandler agentEvenHandler() {
return new AgentEventHandler();
}
}
当我发布到REST资源时，实体得到持久化但方法handleBeforeSave永远不会被调用。我错过了什么？
When I am POSTing to the REST resource, the Entity gets persisted but the method handleBeforeSave never gets invoked. What am I missing?
我正在使用：Spring Boot 1.1.5.RELEASE
I'm using: Spring Boot 1.1.5.RELEASE
推荐答案
有时候明显的错误会被忽视。
Sometimes obvious mistakes go unnoticed.
POST - 一个Spring Data REST资源，发出 BeforeCreateEvent 。要捕获此事件，方法handleBeforeSave必须使用@HandleBeforeCreate而不是@HandleBeforeSave进行注释（后者在PUT和PATCH HTTP调用时调用）。
POST-ing a Spring Data REST resource, emits a BeforeCreateEvent. To catch this event, the method handleBeforeSave must be annotated with @HandleBeforeCreate instead of @HandleBeforeSave (the latter gets invoked on PUT and PATCH HTTP calls).
测试成功通过我的（已清理）演示应用程序。
Tests pass successfully on my (cleaned up) demo app now.
