我试图将一个RepositoryEventHandler添加到如下所示的REST存储库中:
@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:
@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组件中声明它:
@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,实体被持久化,但是方法handleBeforeSave从未被调用.我失踪了什么
我使用的是:Spring Boot 1.1.5.RELEASE
解决方法
有时候明显的错误不会被忽视.
发布一个Spring Data REST资源时,会发出一个BeforeCreateEvent.要捕获此事件,必须使用@HandleBeforeCreate而不是@HandleBeforeSave注入方法handleBeforeSave(后者在PUT和PATCH HTTP调用中被调用).
测试成功通过我的(清理)demo app.
