ofbiz的分页入门

ofbiz编程语法写的都很繁琐，密密麻麻的。
我在目录.\framework\common\src\org\ofbiz\common\FindServices发现一个最简单的分页写法吧

java 代码

public static Map performFindList(DispatchContext dctx, Map context) {
       Map result = performFind(dctx,context);

       Integer viewSize = (Integer) context.get("viewSize");  //获取每页的条数
       if (viewSize == null) viewSize = new Integer(20);       // 默认是20
       Integer viewIndex = (Integer) context.get("viewIndex"); //当前的页码
       if (viewIndex == null)  viewIndex = new Integer(0);  // 默认是0

       int start = viewIndex.intValue() * viewSize.intValue();
       List list = null;
       Integer listSize = null;
       try{
           EntityListIterator it = (EntityListIterator) result.get("listIt");
           list = it.getPartialList(start+1, viewSize.intValue()); // list starts at '1'
           it.last();
           listSize = new Integer(it.currentIndex());
           it.close();
       } catch (Exception e) {
           Debug.logInfo("Problem getting partial list" + e,module);
       }

       result.put("listSize", listSize);
       result.put("list",list);
       result.remove("listIt");
       return result;
   }
