1.restful接口被调用

首先要设置拦截，否则无法直接访问

接口测试方法

package test;

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.HttpURLConnection;
import java.net.URL;
/**
* @author 包福平
* @QQ:1140913970
*/
public class ToInterface {
/**
* 调用对方接口方法
* @param path 对方或第三方提供的路径
* @param data 向对方或第三方发送的数据，大多数情况下给对方发送JSON数据让对方解析
*/
public static void interfaceUtil(String path,String data) {
try {
URL url = new URL(path);
//打开和url之间的连接
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
PrintWriter out = null;
//请求方式
// conn.setRequestMethod("POST");
// //设置通用的请求属性
conn.setRequestProperty("accept", "*/*");
conn.setRequestProperty("connection", "Keep-Alive");
conn.setRequestProperty("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)");
//设置是否向httpUrlConnection输出，设置是否从httpUrlConnection读入，此外发送post请求必须设置这两个
//最常用的Http请求无非是get和post，get请求可以获取静态页面，也可以把参数放在URL字串后面，传递给servlet，
//post与get的不同之处在于post的参数不是放在URL字串里面，而是放在http请求的正文内。
conn.setDoOutput(true);
conn.setDoInput(true);
//获取URLConnection对象对应的输出流
out = new PrintWriter(conn.getOutputStream());
//发送请求参数即数据
out.print(data);
//缓冲数据
out.flush();
//获取URLConnection对象对应的输入流
InputStream is = conn.getInputStream();
//构造一个字符流缓存
BufferedReader br = new BufferedReader(new InputStreamReader(is));
String str = "";
while ((str = br.readLine()) != null) {
System.out.println(str);
}
//关闭流
is.close();
//断开连接，最好写上，disconnect是在底层tcp socket链接空闲时才切断。如果正在被其他线程使用就不切断。
//固定多线程的话，如果不disconnect，链接会增多，直到收发不出信息。写上disconnect后正常一些。
conn.disconnect();
System.out.println("完整结束");
} catch (Exception e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
interfaceUtil("http://localhost:8080/jsc/toInterfaceController.do?getDemo&body=2", "");
// interfaceUtil("http://192.168.10.89:8080/eoffice-restful/resources/sys/oadata", "usercode=10012");
// interfaceUtil("http://192.168.10.89:8080/eoffice-restful/resources/sys/oaholiday",
// "floor=first&year=2017&month=9&isLeader=N");
}
}

2.带签名密钥的接口

package test;

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.ConnectException;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.HashMap;
import java.util.Map;

public class HttpUtil {

   /**
   * 发起https请求并获取结果
   *
   * @param requestUrl
   * 请求地址
   * @param requestMethod
   * 请求方式（GET、POST）
   * @param outputStr
   * 提交的数据
   * @return JSONObject(通过JSONObject.get(key)的方式获取json对象的属性值)
   */
   public static JSONObject httpRequest(String requestUrl,
           String requestMethod, String outputStr,String sign) {
       JSONObject jsonObject = null;

           URL url = new URL(requestUrl);
       httpUrlConn = (HttpURLConnection) url.openConnection();
           httpUrlConn.setDoOutput(true);

           if ("GET".equalsIgnoreCase(requestMethod))
               httpUrlConn.connect();

           // 当有数据需要提交时
           if (null != outputStr) {
