SpringBoot/JPA/MongoDB @CreatedDate 注解不生效

Tags: /Java/ Date Created:

SpringBoot JPA中，MongoDB，实体类定义：

@Document
public class Demo {
  @Id private final String id;
  private String name;
  @CreatedDate
  private Date creationDate;
  @LastModifiedDate
  private Date updateDate;
}

@CreatedDate注解不生效，但是@LastModifiedDate运行良好。

解决方法： Spring Data Couchbase - Reference Documentation

1. 必须在配置类，启用 @EnableMongoAuditing

2. 必须定义 @Version 字段：

@Document
public class Demo {
  @Id private final String id;
  private String name;
  @CreatedDate
  private Date creationDate;
  @LastModifiedDate
  private Date updateDate;
  @Version
  private long version;
}
