MP（MyBatis-Plus）实现乐观锁更新功能的示例代码

@Bean
public MybatisPlusInterceptor mybatisPlusInterceptor() {
  MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
  interceptor.addInnerInterceptor(new OptimisticLockerInnerInterceptor());
  return interceptor;
}

@TableField(fill = FieldFill.UPDATE)
@Version
private Date updateTime;

{
 "userId": 367,
 "address": "上海市自由之路xxxxxx...",
 "workUnit": "XXXX",
 "createTime": "2020-12-22T00:00:00.000+08:00",
 "updateTime": "2021-01-08T17:28:14.782+08:00"
}

spring:
 jackson:
  default-property-inclusion: non_null
  time-zone: GMT+8
  date-format: yyyy-MM-dd HH:mm:ss

{
 "userId": 367,
 "address": "上海市自由之路xxxxxx...",
 "workUnit": "XXXX",
 "createTime":"2020-12-22 00:00:00",
 "updateTime":"2021-01-08 17:28:14"
}

spring:
 jackson:
  default-property-inclusion: non_null
  time-zone: GMT+8
  # date-format: yyyy-MM-dd HH:mm:ss

private Date updateTime;

@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
private Date updateTimeSimpleFormat;
updateTimeSimpleFormat不要生成get和set方法，在updateTime的set方法中对updateTimeSimpleFormat进行赋值。


public void setUpdateTime(Date updateTime) {
   this.updateTime = updateTime;
   this.updateTimeSimpleFormat = updateTime;
 }
