一、因为在使用https发送请求的时候会涉及，验证方式。但是这种方式在使用的时候很不方便。特别是在请求外部接口的时候，所以这我写了一个跳过验证的方式。（供参考）

二、加入包，这里用的是commons-httpclient 3.1 的包。一般请求采用最新的httpclient4.5就可以了

       
      
       commons-httpclient
        
      
       commons-httpclient
        
      
       3.1
      
     

三、这里我们实现3个类

1、MyX509TrustManager（这个方法直接实现X509TrustManager，X509TrustManager在javax.net.ssl.X509TrustManager里面）

这里直接实现不用改任何东西

import java.security.cert.CertificateException;import java.security.cert.X509Certificate;import javax.net.ssl.X509TrustManager;public class MyX509TrustManager implements X509TrustManager {    /* (non-Javadoc)    * @see javax.net.ssl.X509TrustManager#checkClientTrusted(java.security.cert.X509Certificate[], java.lang.String)    */    public void checkClientTrusted(X509Certificate[] arg0, String arg1)            throws CertificateException {    }    /* (non-Javadoc)     * @see javax.net.ssl.X509TrustManager#checkServerTrusted(java.security.cert.X509Certificate[], java.lang.String)     */    public void checkServerTrusted(X509Certificate[] arg0, String arg1)            throws CertificateException {    }    /* (non-Javadoc)     * @see javax.net.ssl.X509TrustManager#getAcceptedIssuers()     */    public X509Certificate[] getAcceptedIssuers() {        return null;    }}

2、MySecureProtocolSocketFactory（这里我们需要用到SSLContext，还需要改写一个实现SecureProtocolSocketFactory的方法）

import java.io.IOException;import java.net.InetAddress;import java.net.Socket;import java.net.UnknownHostException;import javax.net.ssl.SSLContext;import javax.net.ssl.TrustManager;import org.apache.commons.httpclient.ConnectTimeoutException;import org.apache.commons.httpclient.HttpClientError;import org.apache.commons.httpclient.params.HttpConnectionParams;import org.apache.commons.httpclient.protocol.ControllerThreadSocketFactory;import org.apache.commons.httpclient.protocol.SecureProtocolSocketFactory;public class MySecureProtocolSocketFactory implements SecureProtocolSocketFactory {    //这里添加一个属性，主要目的就是来获取ssl跳过验证    private SSLContext sslContext = null;    /**     * Constructor for MySecureProtocolSocketFactory.     */    public MySecureProtocolSocketFactory() {    }    /**     * 这个创建一个获取SSLContext的方法，导入MyX509TrustManager进行初始化     * @return     */    private static SSLContext createEasySSLContext() {        try {            SSLContext context = SSLContext.getInstance("SSL");            context.init(null, new TrustManager[] { new MyX509TrustManager() },                    null);            return context;        } catch (Exception e) {            throw new HttpClientError(e.toString());        }    }    /**     * 判断获取SSLContext     * @return     */    private SSLContext getSSLContext() {        if (this.sslContext == null) {            this.sslContext = createEasySSLContext();        }        return this.sslContext;    }    //后面的方法基本上就是带入相关参数就可以了    /*     * (non-Javadoc)     *     * @see org.apache.commons.httpclient.protocol.ProtocolSocketFactory#createSocket(java.lang.String,     *      int, java.net.InetAddress, int)     */    public Socket createSocket(String host, int port, InetAddress clientHost,int clientPort) throws IOException, UnknownHostException {        return getSSLContext().getSocketFactory().createSocket(host, port,clientHost, clientPort);    }    /*     * (non-Javadoc)     *     * @see org.apache.commons.httpclient.protocol.ProtocolSocketFactory#createSocket(java.lang.String,     *      int, java.net.InetAddress, int,     *      org.apache.commons.httpclient.params.HttpConnectionParams)     */    public Socket createSocket(final String host, final int port,final InetAddress localAddress, final int localPort,                               final HttpConnectionParams params) throws IOException,UnknownHostException, ConnectTimeoutException {        if (params == null) {            throw new IllegalArgumentException("Parameters may not be null");        }        int timeout = params.getConnectionTimeout();        if (timeout == 0) {            return createSocket(host, port, localAddress, localPort);        } else {            return ControllerThreadSocketFactory.createSocket(this, host, port,localAddress, localPort, timeout);        }    }    /*     * (non-Javadoc)     *     * @see SecureProtocolSocketFactory#createSocket(java.lang.String,int)     */    public Socket createSocket(String host, int port) throws IOException,UnknownHostException {        return getSSLContext().getSocketFactory().createSocket(host, port);    }    /*     * (non-Javadoc)     *     * @see SecureProtocolSocketFactory#createSocket(java.net.Socket,java.lang.String,int,boolean)     */    public Socket createSocket(Socket socket, String host, int port,boolean autoClose) throws IOException, UnknownHostException {        return getSSLContext().getSocketFactory().createSocket(socket, host,port, autoClose);    }}

3、然后就是httpclient了，这里实现的方式很单间了，只要声明MySecureProtocolSocketFactory加入就可以了Protocol

import org.apache.commons.httpclient.methods.GetMethod;import org.apache.commons.httpclient.protocol.Protocol;import org.apache.commons.httpclient.protocol.ProtocolSocketFactory;/* * 利用HttpClient进行post请求的工具类 */public class HttpClientUtil {    public static String doGet(String url) throws Exception {        //声明        ProtocolSocketFactory fcty = new MySecureProtocolSocketFactory();        //加入相关的https请求方式        Protocol.registerProtocol("https", new Protocol("https", fcty, 443));        //发送请求即可        org.apache.commons.httpclient.HttpClient httpclient = new org.apache.commons.httpclient.HttpClient();        GetMethod httpget = new GetMethod(url);        System.out.println("======url:" + url);        try {            httpclient.executeMethod(httpget);            return httpget.getResponseBodyAsString();        } catch (Exception ex) {            ex.printStackTrace();            throw new Exception(ex.getMessage());        } finally {            httpget.releaseConnection();        }    }}

四、这里基本上就完成了，在会用的时候只要声明MySecureProtocolSocketFactory加入就可以了Protocol，然后就可以实现验证的跳过过了
