微信小程序商城，前端PHP后端java，怎么部署呢？

打开项目根目录文件夹下。执行 mvn eclipse:eclipse命令，会生成项目结构，然后在eclipse导入就可以，不过有缘分的是我们用到了一个项目，哈哈，望给个最佳奥，可以一起探讨

小程序后台获取openId解密的java代码怎么写

一、获取code

将code作为参数传递过来

//如果有code，说明是微信小程序，根据code获取openId

//classify用于标识是哪个小程序

if (!CheckUtil.checkNulls( keUser.getCode(),keUser.getClassify())){

//

String openid = OpenIdUtil.oauth2GetOpenid(keUser.getCode(),keUser.getClassify());

printParamsLog(openid, logger);

keUser.setUserId(openid);

}1234567812345678

二、工具类

package com.util;

import net.sf.json.JSONObject;

import org.apache.http.client.HttpClient;

import org.apache.http.client.ResponseHandler;

import org.apache.http.client.methods.HttpGet;

import org.apache.http.impl.client.BasicResponseHandler;

import org.apache.http.impl.client.DefaultHttpClient;

import java.util.HashMap;

import java.util.Map;

/**

* @author xsx

*/

public class OpenIdUtil {

public static String oauth2GetOpenid(String code,String classify) {

String appid="";

String appsecret="";

switch (classify){

case "1":

//自己的配置appid

appid = "**********";

//自己的配置APPSECRET;

appsecret = "**********";

break;

case "2":

appid = "**********";

appsecret = "************";

break;

case "3":

appid = "**********";

appsecret = "************";

break;

case "4":

appid = "**********";

appsecret = "************";

break;

case "5":

appid = "**********";

appsecret = "************";

}

//授权（必填）

String grant_type = "authorization_code";

//URL

String requestUrl = "";

//请求参数

String params = "appid=" + appid + "secret=" + appsecret + "js_code=" + code + "grant_type=" + grant_type;

//发送请求

String data = HttpUtil.get(requestUrl, params);

//解析相应内容（转换成json对象）

JSONObject json = JSONObject.fromObject(data);

//用户的唯一标识（openid）

String Openid =String.valueOf(json.get("openid"));

//System.out.println(Openid);

return Openid;

}

}

三、发送请求的工具类

package com.util;

import java.io.BufferedReader;

import java.io.InputStreamReader;

import java.net.URL;

import java.net.URLConnection;

import java.util.List;

import java.util.Map;

/**

* @author xsx

*/

public class HttpUtil {

/**

* 向指定URL发送GET方法的请求

*

* @param url

* 发送请求的URL

* @param param

* 请求参数，请求参数应该是 name1=value1name2=value2 的形式。

* @return String 所代表远程资源的响应结果

*/

public static String get(String url,String param){

String result = "";

BufferedReader in = null;

try {

String urlNameString = url + "?" + param;

//System.out.println(urlNameString);

URL realUrl = new URL(urlNameString);

// 打开和URL之间的连接

URLConnection connection = realUrl.openConnection();

// 设置通用的请求属性

connection.setRequestProperty("accept", "*/*");

connection.setRequestProperty("connection", "Keep-Alive");

connection.setRequestProperty("user-agent",

"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");

// 建立实际的连接

connection.connect();

// 获取所有响应头字段

MapString, ListString map = connection.getHeaderFields();

// 遍历所有的响应头字段

/*for (String key : map.keySet()) {

System.out.println(key + "---" + map.get(key));

}*/

// 定义 BufferedReader输入流来读取URL的响应

in = new BufferedReader(new InputStreamReader(

connection.getInputStream()));

String line;

while ((line = in.readLine()) != null) {

result += line;

}

} catch (Exception e) {

System.out.println("发送GET请求出现异常！" + e);

e.printStackTrace();

}

// 使用finally块来关闭输入流

finally {

try {

if (in != null) {

in.close();

}

} catch (Exception e2) {

e2.printStackTrace();

}

}

return result;

}

}

如何用java实现抓取商城商品信息到自己的页面上来！！！ 求解啊，大神们！！

对于加密的网站还没去研究，不知道能不能抓取，现在只是对一些没有加密的网站进行网页数据抓取。刚刚开始写的时候以为很多网站都能抓取，但是发现很多都加密了，本来以为一些地址可以通过网页数据检测工具测出他的数据变化，但是只能监测到一些通过js显示的数据，依然不能抓取到加密的网站。嗨，这个问题以后再说吧。

Java~有哪位大虾可以帮我写一个小程序呀,用Java做一个界面,上面有四个按钮分别是红色,黄色,蓝色,退出,

import java.awt.Color;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import javax.swing.JButton;

import javax.swing.JFrame;

import javax.swing.JPanel;

public class Screen{

public static void main(String args[]){

new Win();

}

static class Win extends JFrame implements ActionListener{

JPanel jp = new JPanel();

JButton jb[] = new JButton[4];

public Win(){

this.setBounds(0, 0, 320, 320);

Color c[] = {Color.red,Color.yellow,Color.blue};

jp.setBackground(Color.black);

for(int i = 0 ; i 4 ; i++){

jb[i] = new JButton();

if(i!=3){

jb[i].setBackground(c[i]);

}else{

jb[i].setText("退出");

}

jb[i].addActionListener(this);

jp.add(jb[i]);

}

this.add(jp);

this.setVisible(true);

}

public void actionPerformed(ActionEvent e) {

if(!((JButton)e.getSource()).getText().equals("退出")){//如果不是退出按钮，则换颜色

jp.setBackground(((JButton)e.getSource()).getBackground());

}

else

System.exit(0);//退出

}

}

}
