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
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;
}
}
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。
