将String转换为Date时，JDK5 / JDK 6有什么不同 [英] Is there any difference on JDK5/JDK 6 when converting String to Date

问题描述

JDK 5是否可以生成

Could it possible that JDK 5 can produce

"default message [Failed to convert property value of type 
'java.lang.String' to required type 'java.util.Date' for property 
'orderDate'; nested exception is  org.springframework.core.convert.ConversionFailedException:Failed to convert
from type java.lang.String to type java.util.Date for value 'Mon May 27 12:27:20 ART 2013'"

但不是JDK6？目前的应用是Spring在JBoss上，所以转换不明确。我从一台机器上的Jboss服务器上得到这个问题，但不是从另一台机器上的其他Jboss得到这个问题。但是现在不知何故，我无法检查服务器的JVM细节问题。

But not on JDK6? current application is Spring on JBoss so that the conversion is not explicit. I get this issue from Jboss server on one machine but not from other Jboss on another machine. However right now somehow I can not check the JVM detail with the server has the issue.

推荐答案

我怀疑JDK Date函数有显着性从版本5更改为6.也许这是两个环境之间的区域设置差异。

I doubt JDK Date functions has significant change from version 5 to 6. Maybe it's locale differences between two environments.

另外，如果您使用的是Spring MVC，则更好的做法是定义日期字符串格式，并注册一个属性编辑器在你的控制器，所以你可以随时解析/格式，无论区域设置，例如：

Also if you're on Spring MVC it's better practice to define a date string format, and register a property editor for it on your controller, so you can always parse/format regardless of locales, eg:

@InitBinder
public void registerDateBinder(WebDataBinder binder) {
  DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
  binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, true));
}
