4、service代码
@Override
public Map<String,Object> query(String type, Integer pageNo, Integer pageSize) {
pageNo = pageNo == null?1:pageNo;
pageSize = pageSize == null?10:pageSize;
PageHelper.startPage(pageNo, pageSize);
List<Category> list = this.dao.selectCategoryByType(type);
for(Category c:list)
{
System.out.println(c);
}
//用PageInfo对结果进行包装
PageInfo<Category> page = new PageInfo<Category>(list); //测试PageInfo全部属性
/*
System.out.println(page.getPageNum());
System.out.println(page.getPageSize());
System.out.println(page.getStartRow());
System.out.println(page.getEndRow());
System.out.println(page.getTotal());
System.out.println(page.getPages());
System.out.println(page.getFirstPage());
System.out.println(page.getLastPage());
System.out.println(page.isHasPreviousPage());
System.out.println(page.isHasNextPage());*/
Map<String, Object> map=new HashMap<String, Object>();
map.put("total", page.getTotal());
map.put("rows", page.getList());
return map;
}
5、controller代码
@ResponseBody
@RequestMapping(value = "/list")
public Map<String, Object> getCategories(HttpServletRequest request,HttpServletResponse response) {
int page=Integer.parseInt(request.getParameter("page"));
int rows=Integer.parseInt(request.getParameter("rows"));
String type=request.getParameter("type");
return categoryService.query(type, page, rows);
}
6、easyui调用

7、总结说明
（1）注意bean的getter、setter写法，不能这么写getcName,要这么写getCName,否则fastjson会找不到cName属性
（2）暂时不要用fastjson 1.2.10,有bug.会抛出 java.lang.AbstractMethodError异常
（3）<mvc:default-servlet-handler />处理静态资源，不要用mvc:resources，不好用，容易出问题；
（4）静态资源最好用如下方式:
head.jspf：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<c:set value="${pageContext.request.contextPath }" var="shop" />
<title>my website</title>
<link rel="stylesheet"
href="${shop}/jquery-easyui-1.3.5/themes/default/easyui.css" type="text/css" />
<link rel="stylesheet" href="${shop}/jquery-easyui-1.3.5/themes/icon.css"
type="text/css" />
<script type="text/javascript"
src="${shop}/jquery-easyui-1.3.5/jquery.min.js"></script>
<script type="text/javascript"
src="${shop}/jquery-easyui-1.3.5/jquery.easyui.min.js"></script>
<script type="text/javascript"
