Question

我正在为调用Date.parse（）的方法编写测试。代码看起来像这样

    public void someMethod(String s){

         Date date = new Date();

         date.setTime(Date.parse(s));

         //other methods
    }

在我的测试中，我做了类似的事情

    public void test(){
          ...

          Date date = new Date();
          someMethod(date.toString());

          //assert statements
    }

它在我的机器上运行良好，我在我的日食和IntelliJ IDEA中尝试过。但是，当我将它推送到我们的服务器进行构建时，测试失败。它抛出IllegalArgumentException。我的队友也收到同样的例外。我们使用相同的sdk：jdk1.7.0和IDE eclipse和IntelliJ。唯一的区别是我的机器上安装了jre7。我也尝试了一个简单的测试：

    public void test(){
          Date d = new Date();
          String s = d.toString();

          Date e = new Date();
          e.setTime(Date.parse(s));

          sysout(e);
    }

在我的机器上运行良好，但在他的机器中收到IllegalArgumentException。我无法更改测试中的方法，因此我无法执行从字符串到日期的其他转换。感谢

抱歉我无法正确编辑，我的机器中禁用了javascript

Answer 1

Date.toString()和Date.parse()与语言环境有关。因此，toString()可能无法明确地读取parse()的输出。传递日期的时间戳会更好，因为这只是一个数字，因此是唯一的。

Answer 2

根据Javadocs Date.parse()自JDK 1.1起已被弃用

因此，您最好更改以下代码：

Date d = new Date();
String s = d.toString();

Date e = new Date();
e.setTime(Date.parse(s));

有这样的事情：

Date d = new Date();

Date e = new Date(); 
e.setTime(d.getTime());

Answer 3

虽然这可能无法解决您的问题，但我认为查看DateFormatter课程对您的案例非常有帮助。

Answer 4

Date.parse（）已弃用。更改方法如下，然后再试一次。

public void someMethod(String s){
     Date date = new Date();
     try {
      date=DateFormat.getDateInstance().parse(s);
     } catch (ParseException e) {

     e.printStackTrace();
     }


     //other methods
}

Java Date.parse IllegalArgument
