Question

我写这段代码，我正在比较这两个日期，但我得到额外的-4：00，我不知道它来自哪里因为我指定我想要yyyy-MM-dd＆＃39; T＆＃ 39; HH：mm：ss以秒结束，所以我不知道如何摆脱-4：00。

   @Test
   public void testOrder5() throws Exception {
      Phone input = new DefaultPhone();
      SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
      Date date = new Date();
      input.setCreatedDate(date);
      Phoneobj output = Book.change(input);
      assertThat(output.getCreatedDate(), is(sf.format(date)));
   }

错误是

java.lang.AssertionError: 
Expected: is "2013-10-09T14:27:10"
     got: "2013-10-09T14:27:10-04:00"

所以我不确定-4：00来自哪里或如何摆脱它

public class Defaultphone implements Phone{
private Date createdDate;

@Override public Date getCreatedDate()
{
    return createdDate;
}

@Override public void setCreatedDate(Date createdDate)
{
    this.createdDate = createdDate;
}
}

然后我的改变方法包括

public static PhoneObj change(Order from) {
     PhoneObj phoneobj = new OrderDto();
    if (from.getCreatedDate() != null) {
             phoneobj.setCreatedDate(dateTimeFormatter.print(from.getCreatedDate().getTime()));
          }
return phoneobj;
}

Answer 1

你必须在你的测试中改变你的模式：

SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssXXX");

使用此模式，您将获得PhoneObj类中使用的相同格式。

Answer 2

看起来output.getCreatedDate（）返回“2013-10-09T14：27：10-04：00”。我确定你是否调试了该行的输出对象 - ＆gt; Phoneobj输出= Book.change（输入）; 你会知道原因。

如果您无法找到，请分享更改Book.change（输入）。
