Annotation Type JsonFormat

Posted 2020-10-08

最近在调试接口时发现：接口传递过来的jSON数据格式中时间格式是字符串的形式：

{"name":"满300送50",
	"merchantId":"1",
	"needMoney":"100",
	"money":"50",
	"useMoney":"300",
	"beginDatetime":"2017-09-27 10:00:00",
	"endDatetime":"2017-09-27 10:00:00"
}

而java绑定的实体文件是Date格式的：

private Date beginDatetime;
@JsonFormat(pattern="yyyy-MM-dd HH:mm:ss",timezone = "GMT+8")
    public Date getBeginDatetime() {
        return beginDatetime;
    }

    public void setBeginDatetime(Date beginDatetime) {
        this.beginDatetime = beginDatetime;
    }

调用接口的时候就会报HTTP Status 400 – Bad Request的错误，表示

The server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing).

在getter方法上添加@JsonFormat注解

@JsonFormat(pattern="yyyy-MM-dd HH:mm:ss",timezone = "GMT+8")
    public Date getBeginDatetime() {
        return beginDatetime;
    }
