String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";Date dNow = new Date(); //当前时间Date dBefore = new Date();Calendar calendar = Calendar.getInstance(); //得到日历calendar.setTime(dNow);//把当前时间赋给日历calendar.add(Calendar.DAY_OF_MONTH, -1); //设置为前一天dBefore = calendar.getTime(); //得到前一天的时间SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); //设置时间格式String defaultStartDate = sdf.format(dBefore); //格式化前一天String defaultEndDate = sdf.format(dNow); //格式化当前时间System.out.println("前一天的时间是：" + defaultStartDate);System.out.println("生成的时间是：" + defaultEndDate);

Calendar calendar = Calendar.getInstance();calendar.add(Calendar.DATE, -1); //得到前一天Date date = calendar.getTime();DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");System.out.println(df.format(date));
