前后端分离RestFul 日期处理规范

原文参考：https://blog.csdn.net/qq_35706771/article/details/82955775

Restful：一种软件架构风格、设计风格，而不是标准，只是提供了一组设计原则和约束条件。它主要用于客户端和服务器交互类的软件。基于这个风格设计的软件可以更简洁，更有层次，更易于实现缓存等机制。

前后端分离，前端传："yyyy-MM-dd HH:mm:ss"，后端在用Date 类型变量接收参数时候，需在接收对象上加：@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
例如

    @ApiModelProperty(value = "生效时间")
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    private Date effectiveTime;

    @ApiModelProperty(value = "过期时间")
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    private Date expirationTime;

注: 1、HH:mm:ss 是24小时制，hh:mm:ss 是12小时制
