Mongotemplate.updateFirst()不会更新@LastModifiedDate [英] Mongotemplate.updateFirst() doesn't update @LastModifiedDate

问题描述

我正在使用基于注释的配置.

I'm using annotation based configuration.

@Configuration
@Profile("default")
@ComponentScan(basePackages = "com.*")
@EnableMongoRepositories
@EnableMongoAuditing
public class ApplicationDataConfig ....

我还对类型为org.joda.time.DateTime的字段设置了@LastModifiedDate，@CreatedDate批注.当我使用

And I also have @LastModifiedDate, @CreatedDate annotation set on fields of type org.joda.time.DateTime. When I use

org.springframework.data.mongodb.repository.MongoRepository.save(实体)

org.springframework.data.mongodb.repository.MongoRepository.save(entity)

两个审计字段都可以很好地更新.但是当我使用

both the audit fields are updated just fine. But when I use

org.springframework.data.mongodb.core.MongoTemplate.updateFirst()/updateMulti()

org.springframework.data.mongodb.core.MongoTemplate.updateFirst()/updateMulti()

上次更新时间未更新.有人知道什么地方可能出问题了吗?我正在使用spring-data-mongodb1.8.3

the lastupdated time is not being updated. Does anybody have a clue of what could be wrong? I'm using spring-data-mongodb1.8.3

推荐答案

我发现@Id字段在save()时需要为空 仅用于@CreatedDate和@CreatedBy批注.这 @LastModifiedDate和@LastModifiedBy字段不管 @Id字段是否已初始化.

I found that the @Id field needed to be null at the time of save() only for the @CreatedDate and @CreatedBy annotations. The @LastModifiedDate and @LastModifiedBy fields worked regardless of whether the @Id field was initialized or not.
