【SpringBoot】中工夫类型 序列化、反序列化、格局解决

Date

yml 全局配置

spring:  
  jackson:
    time-zone: GMT+8
    date-format: yyyy-MM-dd HH:mm:ss #配置 POST 申请 Body 中 Date 工夫类型序列化格局解决，并返回

申请参数类型转换

/**
 * 工夫 Date 转换
 * 配置 GET 申请，Query 查问 Date 工夫类型参数转换
 */
@Component
public class DateConverter implements Converter<String, Date> {
  @Override
