1.数据库配置： application-dev.yml中可以设置username和password 2.ajax提交请求data参数设置 data：{"hostname"：row.hostname} controller接收参数时候参数名称要和hostname一致 3.关于Java实现Https请求的参考博客：
1). JAVA实现HTTPS协议POST请求JSON报文
package https; import java.io.ByteArrayOutputStream; import java.io.DataOutputStream; import java.io.IOException; import java.io.InputStream; import java.net.URL; import java.security.KeyManagementException; import java.security.NoSuchAlgorithmException; import java.security.cert.CertificateException; import java.security.cert.X509Certificate; import javax.net.ssl.HostnameVerifier; import javax.net.ssl.HttpsURLConnection; import javax.net.ssl.SSLContext; import javax.net.ssl.SSLSession; import javax.net.ssl.TrustManager; import javax.net.ssl.X509TrustManager; import net.sf.json.JSONArray; import net.sf.json.JSONObject; public class PostJson { private static class TrustAnyTrustManager implements X509TrustManager { //该方法检查客户端的证书，若不信任该证书则抛出异常。由于我们不需要对客户端进行认证，因此我们只需要执行默认的信任管理器的这个方法。 //JSSE中，默认的信任管理器类为TrustManager。 public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException { } //该方法检查服务器的证书，若不信任该证书同样抛出异常。通过自己实现该方法，可以使之信任我们指定的任何证书。在实现该方法时，也可以简单的不做任何处理，即一个空的函数体，由于不会抛出异常，它就会信任任何证书。 public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException { } //返回受信任的X509证书数组。 public X509Certificate[] getAcceptedIssuers() { return new X509Certificate[] {}; } } private static class TrustAnyHostnameVerifier implements HostnameVerifier { public boolean verify(String hostname, SSLSession session) { return true; } } /** * post方式请求服务器(https协议) * * @param url * 请求地址 * @param content * 参数 * @param charset * 编码 * @return * @throws NoSuchAlgorithmException * @throws KeyManagementException * @throws IOException */ public static byte[] post(String url, String content, String charset) throws NoSuchAlgorithmException, KeyManagementException, IOException { /*类HttpsURLConnection似乎并没有提供方法设置信任管理器。其实，HttpsURLConnection通过SSLSocket来建立与HTTPS的安全连接，SSLSocket对象是由SSLSocketFactory生成的。 * HttpsURLConnection提供了方法setSSLSocketFactory(SSLSocketFactory)设置它使用的SSLSocketFactory对象。 * SSLSocketFactory通过SSLContext对象来获得，在初始化SSLContext对象时，可指定信任管理器对象。 * */ SSLContext sc = SSLContext.getInstance("SSL"); sc.init(null, new TrustManager[] { new TrustAnyTrustManager() }, new java.security.SecureRandom()); URL console = new URL(url); HttpsURLConnection conn = (HttpsURLConnection) console.openConnection(); conn.setSSLSocketFactory(sc.getSocketFactory()); conn.setHostnameVerifier(new TrustAnyHostnameVerifier()); conn.setDoOutput(true); //设置请求头 conn.setRequestProperty("Content-Type", "application/json;charset=utf-8"); conn.connect(); DataOutputStream out = new DataOutputStream(conn.getOutputStream()); out.write(content.getBytes(charset)); // 刷新、关闭 out.flush(); out.close(); InputStream is = conn.getInputStream(); // StringBuffer sb=new StringBuffer(); // String readLine=new String(); // BufferedReader responseReader=new BufferedReader(new InputStreamReader(httpConn.getInputStream(),"UTF-8")); // while((readLine=responseReader.readLine())!=null){ // sb.append(readLine).append("\n"); // } // responseReader.close(); // System.out.println(sb.toString()); if (is != null) { ByteArrayOutputStream outStream = new ByteArrayOutputStream(); byte[] buffer = new byte[1024]; int len = 0; while ((len = is.read(buffer)) != -1) { outStream.write(buffer, 0, len); } is.close(); return outStream.toByteArray(); } return null; } public static void main(String[] args) throws KeyManagementException, NoSuchAlgorithmException, IOException{ String url = "https://xxx.xxx.xxx/path/to/dir/${action}"; PostJson pj = new PostJson(); String content=pj.getbaowen(); String charset="UTF-8"; byte[] a = pj.post(url, content, charset); String b = new String(a); System.out.println(b); } //构造嵌套的JSON报文方式，即在new一个JSONObject,并返回报文字符串 public String getbaowen(){ JSONObject test= new JSONObject(); test.put("xxxx", ""); String resp= null; JSONObject obj = new JSONObject(); obj.put("xxxxxx", ""); obj.put("test", test); String query = obj.toString(); return query; } }2). HttpURLConnection与HttpClient区别及使用 性能方面：HttpURLConnection的访问速度比HttpClient要快。
