Spring Data REST事件不起作用

本文介绍了Spring Data REST事件不起作用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我尝试按照以下方式配置spring数据休息事件。所有类都在包 org.springbootjpa

<事件： http：//docs.spring。我/我的代码

@SpringBootApplication 公共类DemoApplication { public static void main（String [] args）{ ApplicationContext context = SpringApplication.run（ DemoApplication.class，args）; String [] beanNames = context.getBeanDefinitionNames（）; Arrays.sort（beanNames）; for（String beanName：beanNames）{ System.out.println（beanName）; } } @Bean GroupEventHandler groupEventHandler（）{返回新的GroupEventHandler（）; } }

事件处理程序

@RepositoryEventHandler（UserGroup.class） public class GroupEventHandler { @HandleBeforeSave public void handleGroupSave（UserGroup group ）{ System.out.println（inside handleGroupSave ....）; } @HandleAfterSave public void handleAfterSave（UserGroup group）{ System.out.println（inside handleAfterSave ....）; } }

实体

@Entity 公共类UserGroup { @Id @GeneratedValue private Long的groupId; @Column private String groupName; .. }

当我将条目发布到userGroups链接时侦听器未被触发。

post --data{groupId：1，groupName：'group1'}

解决方案

如评论中所述， HandleBeforeCreate 。将在PUT请求时触发 HandleBeforeSave 事件。

I have tried to configure spring data rest event as per follows.All classes are in package org.springbootjpa

Events: docs.spring.io/spring-data/rest/docs/current/reference/html/#events

Following is my code

@SpringBootApplication public class DemoApplication { public static void main(String[] args) { ApplicationContext context = SpringApplication.run( DemoApplication.class, args); String[] beanNames = context.getBeanDefinitionNames(); Arrays.sort(beanNames); for (String beanName : beanNames) { System.out.println(beanName); } } @Bean GroupEventHandler groupEventHandler() { return new GroupEventHandler(); } }

Event Handler

@RepositoryEventHandler(UserGroup.class) public class GroupEventHandler { @HandleBeforeSave public void handleGroupSave(UserGroup group) { System.out.println("Inside handleGroupSave ...."); } @HandleAfterSave public void handleAfterSave(UserGroup group) { System.out.println("Inside handleAfterSave ...."); } }

Entity

@Entity public class UserGroup { @Id @GeneratedValue private Long groupId; @Column private String groupName; .. }

When I post an entry to the userGroups link the listener is not getting triggered.

post --data "{groupId:1,groupName:'group1'}"

解决方案

As mentioned in the comments the HandleBeforeCreate should be called in the case of POST request. The HandleBeforeSave event will be fired on PUT request.
