如何在jsp中获取客户端/请求时区？

我正在尝试制作自定义 AuthenticationProcessingFilter 以在成功登录后在会话中保存一些用户数据

这是我的过滤器：

package projects.internal;

import java.io.IOException;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.security.Authentication;
import org.springframework.security.ui.webapp.AuthenticationProcessingFilter;

public class MyAuthenticationProcessingFilter extends AuthenticationProcessingFilter {


 protected void onSuccessfulAuthentication(HttpServletRequest request,
   HttpServletResponse response, Authentication authResult)
   throws IOException {
  super.onSuccessfulAuthentication(request, response, authResult);
  request.getSession().setAttribute("myValue", "My value is set");
 }
}

这是我的 security.xml 文件

<beans:beans xmlns="http://www.springframework.org/schema/security"  
 xmlns:beans="http://www.springframework.org/schema/beans" 
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://www.springframework.org/schema/beans 
 http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

                        http://www.springframework.org/schema/security/spring-security-3.0.xsd">

如何在Java中获取UTC或GMT中的当前日期和时间？

我想获得格林威治标准时间的当前时间戳; 任何想法如何做到这一点？

我设法得到gmt格式的字符串问题是我想将此字符串转换为等效的时间戳对象,即同一时间但作为时间戳对象

SimpleDateFormat sdf= new SimpleDateFormat("yyyy-MM-dd HH:mm:ss zzz");
        sdf.setTimeZone(TimeZone.getTimeZone("GMT"));
        Date date=new Date();
        String s=sdf.format(date);
        System.out.println("GMT: "+s);
        //need to convert the string to equivalent timestamp object
