大家说一下好的分页方法

Question

仅供参考:
  private void locationPage(){        
        this.request = this.getRequest();
        strStartRecord = request.getParameter("startRecord");
if(strStartRecord==null||strStartRecord.length()<=0){
strStartRecord = "0";
} strDisplayLength = request.getParameter("displayLength");
if(strDisplayLength==null||strDisplayLength.length()<=0){
strDisplayLength="10";
} if(!(strDisplayLength==null||strDisplayLength.length()<=0)){
lDisplayLength=Integer.parseInt(strDisplayLength);
}
else lDisplayLength =10; page_location = request.getParameter("page_location");
if(page_location==null||page_location.length()<=0){
page_location = "";
}
try{
if (Integer.parseInt(page_location)<=0)
page_location = "";
}
catch(NumberFormatException e){
page_location = "";
} if(!(page_location.length()==0)){
                String rsCount = request.getParameter("count");
                long lrsCount = Integer.parseInt(rsCount);
                long temp = Integer.parseInt(page_location)*lDisplayLength;
                if (lrsCount >= temp){
  lStartRecord=(Integer.parseInt(page_location)-1)*lDisplayLength;
  strStartRecord = String.valueOf(lStartRecord);
                }
                else {
                  if (lrsCount%lDisplayLength ==0)
                      lStartRecord = lrsCount/lDisplayLength*lDisplayLength - lDisplayLength;
                  else lStartRecord = lrsCount/lDisplayLength*lDisplayLength;
  strStartRecord = String.valueOf(lStartRecord);
                }
}
else if(!(strStartRecord==null||strStartRecord.length()<=0)){
lStartRecord=Integer.parseInt(strStartRecord);
}
    }   public int getCount(){
      return this.count;
   }   public String getStrStartRecord(){
      return this.strStartRecord;
   }   public String getStrDisplayLength(){
      return this.strDisplayLength;
   }   public long getLStartRecord(){
      return this.lStartRecord;
   }   public long getLDisplayLength(){
      return this.lDisplayLength;
   }locationPage（）在做数据库查询前调用，在做rs结果集循环时：
while (rs.next()){
           i++;
           count++;
           if((i>lStartRecord)&&(i<=(lStartRecord+lDisplayLength))){
           。
           。
           。
           }
}后面的方法在jsp里调用就可以做分页处理了！
