1.java判断同时为空和不为空
@AssertTrue(message = "支付渠道编码[payChannelCode]与授权码[authCode]不能同时存在或同时为空")
@JSONField(serialize = false)
public Boolean getDepositParamIsValid() {
return !StrUtil.isAllNotBlank(this.payChannelCode, this.authCode) || !StrUtil.isAllBlank(this.payChannelCode, this.authCode);
}
优雅写法：
if ((from == null) != (password == null))
{ ... }
可读性写法：
if ((from == null) && (password != null))
{ throw new IllegalArgumentException("If from is null, password must be null"); }
if ((from != null) && (password == null))
{ throw new IllegalArgumentException("If from is not null, password must not be null"); }
