java – Spring Data Rest:RepositoryEventHandler方法未被调用

            导读: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 CrudRepositoryAgent, Long { //
                
                
                
            | 
                         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. (编辑:莱芜站长网) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容!  |
