3、数据接口处理

问题描述：

为数据可视化化提供数据接口支持
包括页面访问情况、用户注册情况

核心源代码：

package demo;

import java.math.BigDecimal;
import java.util.List;

import com.alibaba.fastjson.JSONObject;
import com.jfinal.core.Controller;

import demo.model.IpVisitDetailesModel;
import demo.model.PageViewsModel;
import demo.model.PageVistiDetailsModel;
import demo.model.RegisterNumberModel;

public class APIController extends Controller {
    public void index(){
        renderText("api的index方法正常");
    }
    
    /**
     * 获取ip地区分布状况
     */
    public void getIpDistribution(){
        String sql="select region as name,count(*) as value from IpVisitDetailes group by region";
        List datas= IpVisitDetailesModel.DAO.find(sql);
        
        String result="";
        for(int i=0;i datas=PageViewsModel.DAO.find(sql);
        sql="select sum(number) as total from PageViews";
        PageViewsModel model=PageViewsModel.DAO.findFirst(sql);
        BigDecimal total=model.getBigDecimal("total");
        JSONObject jsonObject=new JSONObject();
        jsonObject.put("datas", datas);
        jsonObject.put("total", total);
        renderJson(jsonObject);
    }
    
    /**
     * 获取注册用户数量-以小时为单位
     */
    public void getRegisterNumber(){
        String sql="select * from RegisterNumber";
        List datas=RegisterNumberModel.DAO.find(sql);
        sql="select sum(number) as total from RegisterNumber";
        RegisterNumberModel model=RegisterNumberModel.DAO.findFirst(sql);
        BigDecimal total=model.getBigDecimal("total");
        JSONObject jsonObject=new JSONObject();
        jsonObject.put("datas", datas);
        jsonObject.put("total", total);
        renderJson(jsonObject);
    }
    
    /**
     * 获取页面访问详情
     */
    public void getPageVistiDetails(){
        String sql="select * from PageVistiDetails";
        List datas=PageVistiDetailsModel.DAO.find(sql);
        renderJson(datas);
    }
    
    /**
     * 获取跳出率
     */
    public void getJumpPencent(){
        String sql="select count(*) as total from IpVisitDetailes";
        Long total=IpVisitDetailesModel.DAO.findFirst(sql).getLong("total");
        
        sql="select count(*) as total from IpVisitDetailes where number=1";
        Long jumpNumber=IpVisitDetailesModel.DAO.findFirst(sql).getLong("total");
        
        double jumpPencent=(double)jumpNumber/(double)total;
        JSONObject jsonObject=new JSONObject();
        jsonObject.put("total", total);
        jsonObject.put("jumpPencent", jumpPencent);
        jsonObject.put("jumpNumber", jumpNumber);
        renderJson(jsonObject);
    }
}
