记录feign调用的LocalDateTime字段转换失败的坑

关键的异常信息如下：

Caused by: java.time.format.DateTimeParseException: Text '2023-05-19 11:07:36' could not be parsed: Unable to obtain LocalDateTime from TemporalAccessor: {SecondOfMinute=36, NanoOfSecond=0, MilliOfSecond=0, HourOfAmPm=11, MicroOfSecond=0, MinuteOfHour=7},ISO,GMT+08:00 resolved to 2023-05-19 of type java.time.format.Parsed

同事的feign和bean是这样的：

@FeignClient(value = "xxxx")
public interface MallFeign {

    /**
     * 获取商城分页列表
     */
    @PostMapping("/mall/getMallPage")
    RetResult<PageInfo<Mall>> getMallPage(@RequestBody MallPageSearch search);
}


@Data
@AllArgsConstructor
@ApiModel("商城VO")
public class Mall {

    @ApiModelProperty(value = "商城ID")
    private Integer id;

    @ApiModelProperty(value = "商城名称")
    private String name;

    @ApiModelProperty(value = "备注")
    private String remarkInfo;

    @ApiModelProperty(value = "创建时间")
    @JsonFormat(pattern = "yyyy-MM-dd hh:mm:ss", timezone = "GMT+8")
    private LocalDateTime createTime;
}

@。@表面看上去也没看出什么毛病。。。消费者这个bean和生产者用的是同一个

最终经多次测试，发现2个奇葩问题：

1、必须移除@AllArgsConstructor

2、日期格式，虽然和生产者用的都是一样的yyyy-MM-dd hh:mm:ss，但不改为yyyy-MM-dd HH:mm:ss就始终解析不了
