1.Post方法工具类

public static String verifyBossData(String data){if(StringUtils.isBlank(data)){return null;}//获取配置文件中urlString url = MongoDBUtil.getSystemParamKeyValue("bossServerUrl");String result = null;if(StringUtils.isNotBlank(data)){BufferedReader reader = null;HttpURLConnection conn = null;OutputStreamWriter out = null;StringBuffer strBuf = null;try {URL myUrl = new URL(url);conn = (HttpURLConnection) myUrl.openConnection();    conn.setConnectTimeout(10000);    conn.setRequestMethod("POST");    conn.setDoInput(true);    conn.setDoOutput(true);conn.setUseCaches(false);//POST请求不能使用缓存conn.setRequestProperty("charset", "UTF-8");strBuf = new StringBuffer();out = new OutputStreamWriter(conn.getOutputStream(), "UTF-8");// 发送请求参数out.write(data);// flush输出流的缓冲out.flush();//读取URL的响应reader = new BufferedReader(new InputStreamReader(conn.getInputStream(),"UTF-8"));            String line =null;            while ((line = reader.readLine()) != null) {                strBuf.append(line);            }            result = strBuf.toString();} catch (Exception e) {e.printStackTrace();}finally{try {if(out!=null){                    out.close();                }                if(reader!=null){                reader.close();                }} catch (IOException e) {e.printStackTrace();}}}return result;}

2.Get方法工具类

注意：若data中包含空格，需要特殊处理

data = URLEncoder.encode(data, "UTF-8");

public static String sendGet(String data){if(StringUtils.isBlank(data)){return null;}//获取配置文件中urlString url = MongoDBUtil.getSystemParamKeyValue("bossServerUrl");String result = null;if(StringUtils.isNotBlank(data)){//拼接URLurl += "?"+data;BufferedReader reader = null;HttpURLConnection conn = null;OutputStreamWriter out = null;StringBuffer strBuf = null;try {URL myUrl = new URL(url);conn = (HttpURLConnection) myUrl.openConnection();    conn.setConnectTimeout(10000);    conn.setRequestMethod("Get");    conn.setDoInput(true);    conn.setDoOutput(true);conn.setRequestProperty("charset", "UTF-8");strBuf = new StringBuffer();//读取URL的响应reader = new BufferedReader(new InputStreamReader(conn.getInputStream(),"UTF-8"));            String line =null;            while ((line = reader.readLine()) != null) {                strBuf.append(line);            }            result = strBuf.toString();} catch (Exception e) {e.printStackTrace();}finally{try {if(out!=null){                    out.close();                }                if(reader!=null){                reader.close();                }} catch (IOException e) {e.printStackTrace();}}}return result;}
