ParseException:无法分析日期-类：java.text.DateFormat

我的问题与关于从JSP获取日期的问题不同

现在我有了一个使用Struts 2.2.1的服务器

动作是这样的：

A级是这样的：

当我使用Postman向这个操作发出带有参数{b:2015-01-01}的HTTP POST请求时，我可以正确地获得b

或者，如果我使用jQuery$.ajax编写javascript，datatype=json，并从bootstrap datetime picker插件获取日期。没关系

但是，当其他人使用ios调用此操作并发送相同的字符串时，服务器会引发异常：

如果无法修改请求特定于区域设置日期的发件人，则至少可以在请求中添加参数request\u locale。其余部分由拦截器完成。您可以阅读答案以获得更多帮助

例如：

good_result.jsp 另一个解决方案是更改属性的类型以避免转换错误

public class A{
    private java.lang.String b;
....
}

如果需要将其转换为日期，可以使用DateFormat。

在解析该日期的地方发布代码。@Aleksandr M不重复。我无法从ios call.jsp中获取日期ok。thx@Saifstruts2解析的日期，不是我的代码。该方法是com.opensymphony.xwork2.conversion.impl.XWorkBasicConverter类中的convertValue日期转换是基于区域设置完成的。因此，这是一个dup。您需要：1更改iOS发送的格式，或2创建自定义转换器。我更改了属性的类型，并使用SimpleDataFormatyyy mm dd HH:mm:ssclass中的sdf.parsemethod对其进行了转换。它可以工作。感谢您的帮助。
