    【SpringBoot】 中时间类型 序列化、反序列化、格式处理

    Date

    yml全局配置

    spring:  
      jackson:
        time-zone: GMT+8
        date-format: yyyy-MM-dd HH:mm:ss #配置POST请求Body中Date时间类型序列化格式处理,并返回
    

    请求参数类型转换

    /**
     * 时间Date转换
     * 配置GET请求,Query查询Date时间类型参数转换
     */
    @Component
    public class DateConverter implements Converter<String, Date> {
      @Override
      public Date convert(String source) {
        if (StringUtils.isBlank(source)) {
          return null;
        }
        if (source.matches("^\d{4}-\d{1,2}-\d{1,2}$")) {
          return parseDate(source.trim(), "yyyy-MM-dd");
        }
        if (source.matches("^\d{4}-\d{1,2}-\d{1,2} {1}\d{1,2}:\d{1,2}:\d{1,2}$")) {
          return parseDate(source.trim(), "yyyy-MM-dd HH:mm:ss");
        }
        throw new IllegalArgumentException("Invalid value '" + source + "'");
      }
    
      public Date parseDate(String dateStr, String format) {
        Date date = null;
        try {
          date = new SimpleDateFormat(format).parse(dateStr);
        } catch (ParseException e) {
          log.warn("转换{}为日期(pattern={})错误!", dateStr, format);
        }
        return date;
      }
    }
