**创建证书管理器类**

import java.security.cert.CertificateException;
    import java.security.cert.X509Certificate;
    
    import javax.net.ssl.X509TrustManager;
    
    /** 
     * 证书信任管理器（用于https请求） 
     * 
     */
    public class MyX509TrustManager implements X509TrustManager {
    
    	public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
    	}
    
    	public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
    	}
    
    	public X509Certificate[] getAcceptedIssuers() {
    		return null;
    	}
    }

**服务器主机名校验类**

import javax.net.ssl.HostnameVerifier;
    import javax.net.ssl.SSLSession;
    
    public class NullHostNameVerifier implements HostnameVerifier{
    	
        @Override
        public boolean verify(String hostname, SSLSession session) {
            return true;
        }
    }

**调用测试**

import java.io.BufferedReader;
    import java.io.InputStreamReader;
    import java.io.OutputStreamWriter;
    import java.io.PrintWriter;
    import java.net.URL;
    
    import javax.net.ssl.HttpsURLConnection;
    import javax.net.ssl.SSLContext;
    import javax.net.ssl.SSLSocketFactory;
    import javax.net.ssl.TrustManager;
    
    import cn.com.goevent.weixin.util.MyX509TrustManager;
    
    public class HttpsTest {
    
    	public static void main(String[] args) throws Exception {	
    	    //设置可通过ip地址访问https请求
    	    HttpsURLConnection.setDefaultHostnameVerifier(new NullHostNameVerifier());
    	    TrustManager[] tm = {new MyX509TrustManager()}; 
    	    SSLContext sslContext = SSLContext.getInstance("TLS"); 
    	    sslContext.init(null, tm, new java.security.SecureRandom());  
    	    // 从上述SSLContext对象中得到SSLSocketFactory对象  
    	    SSLSocketFactory ssf = sslContext.getSocketFactory();
        	    String urlStr = "https://192.168.1.10/login_queryLkBySfmc.htm";
        	    URL url = new URL(urlStr);
    	    HttpsURLConnection con = (HttpsURLConnection) url.openConnection();
    	    con.setSSLSocketFactory(ssf); 
        	    con.setRequestMethod("POST"); // 设置以POST方式提交数据
        	    con.setDoInput(true); // 打开输入流，以便从服务器获取数据
        	    con.setDoOutput(true);// 打开输出流，以便向服务器提交数据
    	    //设置发送参数
                String param = "sfmc=测试";
                PrintWriter out = new PrintWriter(new OutputStreamWriter(con.getOutputStream(),"UTF-8"));
                out.print(param);          
                out.flush();
                out.close();
                //读取请求返回值
    	    InputStreamReader in = new InputStreamReader(con.getInputStream(),"UTF-8");
    	    BufferedReader bfreader = new BufferedReader(in);
    	    String result = "";
    	    String line = "";
    	    while ((line = bfreader.readLine()) != null) {
    	    	result += line;
    	    }
    	    System.out.println("result:"+result);    
    	}
    }
