java 如何将string="Sun Jan 02 2011 00:00:00 GMT+0800" 转换日期啊，

Question

String strdate=this.getRequest().getParameter("vehicleInformTime")
System.out.println(strdate);
vehicleInformTime = DateFormate.getDateByStr(strdate);

/**
 * 将String转换为Date
 * @param str  如果日期str 为原始格式, dateFormat不用指定其格式
 * @return
 */
public static Date getDateByStr(String str){
    SimpleDateFormat dateFormat=new SimpleDateFormat();
    Date date=null;
    try {
        date=dateFormat.parse(str);
    } catch (ParseException e) {
        System.out.println("日期转换错误");
        e.printStackTrace();
    }
    return date;        
}

strdate 打印出来后为：Sun Jan 02 2011 00:00:00 GMT+0800

日期转换错误

Answer 1

new SimpleDateFormat("E MMM dd yyyy HH:mm:ss z",Locale.US).parse(str);
前提是后面跟的是GMT+08:00带冒号的
