Dubbo学习-1 请求jsp

jd对外提供服务:https://wx.jdcloud.com

https://wx.jdcloud.com/market/datas/5/10665 对应短信接口，里面有文档的格式

项目中实现天气服务--实践:

1.dubbo单一应用-发起请求jsp

1.1>步骤:

新建web应用->

新建index.jsp->

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
  <head>
    <title>dubbo获取天气数据</title>
    <script type="text/javascript" src="js/jquery.min.js"></script>
    <script type="text/javascript">
      $(function(){
          $("button").click(function(){
              $.ajax({
                  url:"queryWearth",
                  data:{
                      cityCode:"101010100"
                  },
                  type:"post",
                  success:function(data){
                      alert(data)
                  }
              })
          })
      })

    </script>
  </head>
  <body>
  index.jsp发送ajax请求
  <button>获取城市的天气</button>
  </body>
</html>

将min.js导入webContent下新创建的js文件夹中->

编写页面内容如下->

编写服务端->

beans:

package com.weather.beans;

public class Weather {
    private String name;
    private int temp;
    private String wet;
    private String desc;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getTemp() {
        return temp;
    }

    public void setTemp(int temp) {
        this.temp = temp;
    }

    public String getWet() {
        return wet;
    }

    public void setWet(String wet) {
        this.wet = wet;
    }

    public String getDesc() {
        return desc;
    }

    public void setDesc(String desc) {
        this.desc = desc;
    }

    @Override
    public String toString() {
        return "Weather{" +
                "城市='" + name + '\'' +
                ", 温度=" + temp +
                ", 湿度='" + wet + '\'' +
                ", 描述='" + desc + '\'' +
                '}';
    }
}

service:

package com.weather.service;

import com.weather.beans.Weather;

public interface WeatherService {
    Weather queryWeather(String cityCode);
}

package com.weather.service.impl;

import com.weather.beans.Weather;
import com.weather.service.WeatherService;

public class WeatherServiceImpl implements WeatherService {

    @Override
    public Weather queryWeather(String cityCode) {
        Weather weather = new Weather();
        if("101010100".equals(cityCode)){
            weather.setName("北京");
            weather.setWet("99%");
            weather.setTemp(37);
            weather.setDesc("天气潮湿");
        }else if("101020100".equals(cityCode)){
            weather.setName("石家庄");
            weather.setWet("80%");
            weather.setTemp(39);
            weather.setDesc("天气燥热");
        }else{
            weather.setName("全国");
            weather.setWet("70%");
            weather.setTemp(33);
            weather.setDesc("天气较热");
        }
        return weather;
    }
}

servlet:

项目中添加servlet-api.jar包，idea中右键项目，Open module settings 添加lib(可以从tomcat的lib中查找对应的jar包)

package com.weather.servlet;


import com.weather.beans.Weather;
import com.weather.service.WeatherService;
import com.weather.service.impl.WeatherServiceImpl;

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;
import java.io.PrintWriter;

@WebServlet("/queryWearth")
public class WeatherServlet extends HttpServlet {
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        //获取参数cityCode
       String cityCode = req.getParameter("cityCode");
       //调用业务方法
        WeatherService weatherService = new WeatherServiceImpl();
        Weather weather = weatherService.queryWeather(cityCode);
        resp.setContentType("text/html;charset=utf-8");
        PrintWriter  pw = resp.getWriter();
        pw.print(weather.toString());
        pw.flush();
        pw.close();
    }
    protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        doGet(req,resp);
    }
}
tomcat启动项目->
http://localhost:8080/dubbo/ (此处的dubbo是项目部署的名称) 点击按钮alert出来信息
