注：RouteServlet中的有个小判断也要改

package cn.itcast.travel.web.servlet;

import cn.itcast.travel.domain.PageBean;
import cn.itcast.travel.domain.Route;
import cn.itcast.travel.service.RouteService;
import cn.itcast.travel.service.impl.RouteServiceImpl;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

@WebServlet("/route/*")
public class RouteServlet extends BaseServlet {
    private RouteService routeService = new RouteServiceImpl();

    /*
    分页查询
     */
    public void pageQuery(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        //1.接受参数
        String currentPageStr = request.getParameter("currentPage");
        String pageSizeStr = request.getParameter("pageSize");
        String cidStr = request.getParameter("cid");
        //接受rname路线名称
        String rname = request.getParameter("rname");
        rname = new String(rname.getBytes("iso-8859-1"),"utf-8");


        //2.处理参数
        int cid = 0;//类别id
        if(cidStr != null && cidStr.length() > 0 && !"null".equals(cidStr)){
            cid = Integer.parseInt(cidStr);
        }

        int currentPage = 0;//当前页码，默认为第一页
        if (currentPageStr != null && currentPageStr.length() > 0) {
            currentPage = Integer.parseInt(currentPageStr);
        } else {
            currentPage = 1;
        }

        int pageSize = 0;//每页显示条数，默认显示5条
        if (pageSizeStr != null && pageSizeStr.length() > 0) {
            pageSize = Integer.parseInt(pageSizeStr);
        } else {
            pageSize = 5;
        }
        //3. 调用service查询PageBean对象
        PageBean<Route> pb = routeService.pageQuery(cid, currentPage, pageSize,rname);

        //4. 将pageBean对象序列化为json，返回
        writeValue(pb, response);
    }
