最近遇到个需求需要web服务器应用通过https方式请求外部Internet服务器的接口，一开始本地测试时使用以下代码：

String businessCode = "SH30580";
GenerateXml xml = new GenerateXml();
String xmlContent = xml.writeXmlString(businessCode);
// 创建SSLContext对象，并使用我们指定的信任管理器初始化
SSLContext sslContext = SSLContext.getInstance("SSL", "SunJSSE");
sslContext.init(null, new TrustManager[] {new X509TrustForMSL()},new java.security.SecureRandom());
// 从上述SSLContext对象中得到SSLSocketFactory对象
SSLSocketFactory ssf = sslContext.getSocketFactory();

// 创建URL对象
URL myURL = new URL("https://211.144.221.138/mslws/Services/rsa/RsaWebService.svc/security/validateagencyqualification");


System.setProperty("java.protocol.handler.pkgs", "javax.net.ssl");
HostnameVerifier hv = new HostnameVerifier() {
public boolean verify(String urlHostName, SSLSession session) {
return true;
}
};
HttpsURLConnection.setDefaultHostnameVerifier(hv);

// 创建HttpsURLConnection对象，并设置其SSLSocketFactory对象
Proxy proxy = new Proxy(Proxy.Type.HTTP,new InetSocketAddress("10.38.194.30", 8080));//因为服务器使用代理上Internet,设置代理的ip和端口号
HttpsURLConnection httpsConn = (HttpsURLConnection) myURL.openConnection();
httpsConn.setRequestProperty( "Proxy-Authorization", "Basic " + new sun.misc.BASE64Encoder().encode("用户名:密码".getBytes()) );//设置用户名和密码
httpsConn.setSSLSocketFactory(ssf);
// 以POST方式提交
httpsConn.setRequestMethod("POST");
// 设置连接输出
httpsConn.setDoInput(true);
httpsConn.setDoOutput(true);
// Post 请求不能使用缓存
httpsConn.setUseCaches(false);
httpsConn.setRequestProperty("Content-Type","application/xml");
// httpsConn.connect();

//获取输出流
OutputStream os = httpsConn.getOutputStream();
// // 设置输出流字符集
os.write(xmlContent.getBytes("UTF-8"));
os.flush();
os.close();

// 取得该连接的输入流，以读取响应内容
InputStreamReader insr = new InputStreamReader(httpsConn.getInputStream());
// 读取服务器的响应内容并显示
int respInt = insr.read();
while (respInt != -1) {
System.out.print((char) respInt);
respInt = insr.read();
}

import java.io.FileInputStream;
import java.security.KeyStore;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

import javax.net.ssl.TrustManager;
import javax.net.ssl.TrustManagerFactory;
import javax.net.ssl.X509TrustManager;
public class X509TrustForMSL implements X509TrustManager {
/*
* The default X509TrustManager returned by SunX509. We‘ll delegate
* decisions to it, and fall back to the logic in this class if the

*/
X509TrustManager sunJSSEX509TrustManager;
X509TrustForMSL() throws Exception {
// create a "default" JSSE X509TrustManager.
KeyStore ks = KeyStore.getInstance("JKS");
ks.load(new FileInputStream("D:\\jssecacerts"),
"changeit".toCharArray());
TrustManagerFactory tmf =
TrustManagerFactory.getInstance("SunX509");//, "SunJSSE"
tmf.init(ks);
TrustManager tms [] = tmf.getTrustManagers();
/*
* Iterate over the returned trustmanagers, look
* for an instance of X509TrustManager. If found,
* use that as our "default" trust manager.
*/
for (int i = 0; i < tms.length; i++) {
if (tms[i] instanceof X509TrustManager) {
sunJSSEX509TrustManager = (X509TrustManager) tms[i];
return;
}
}
/*
* Find some other way to initialize, or else we have to fail the
* constructor.
*/
throw new Exception("Couldn‘t initialize");
}
/*
* Delegate to the default trust manager.
*/
public void checkClientTrusted(X509Certificate[] chain, String authType)
throws CertificateException {
try {
sunJSSEX509TrustManager.checkClientTrusted(chain, authType);
} catch (CertificateException excep) {
// do any special handling here, or rethrow exception.
}
}
/*
* Delegate to the default trust manager.
*/
public void checkServerTrusted(X509Certificate[] chain, String authType)
throws CertificateException {
try {
sunJSSEX509TrustManager.checkServerTrusted(chain, authType);
} catch (CertificateException excep) {
/*
* Possibly pop up a dialog box asking whether to trust the
* cert chain.
*/
}
}
/*
* Merely pass this through.
*/
public X509Certificate[] getAcceptedIssuers() {
return sunJSSEX509TrustManager.getAcceptedIssuers();
}
}

Eclipse测试没问题，但是发布到WebSphere中报错，说不支持SunJSSE，查了半天，原来IBM不支持sun公司的jdk中的jsse.jar包，网上说有自己添加的，也有说把证书加入哪里的，或许因为本人愚笨，搞了大半天，p用没有，最后终于悟得以下方法：

public static void main(String args[]) throws Exception{
// 创建SSLContext对象，并使用我们指定的信任管理器初始化
SSLContext sslContext = SSLContext.getInstance("SSL", "SunJSSE");

sslContext.init(null, new TrustManager[] {new TrustAnyTrustManager()},new java.security.SecureRandom());
// 从上述SSLContext对象中得到SSLSocketFactory对象
SSLSocketFactory ssf = sslContext.getSocketFactory();
// 创建URL对象
URL myURL = new URL("https://211.144.221.138/mslws/Services/rsa/RsaWebService.svc/security/validateagencyqualification");

String businessCode = "SH30580";
GenerateXml xml = new GenerateXml();
String xmlContent = xml.writeXmlString(businessCode);

// 创建HttpsURLConnection对象，并设置其SSLSocketFactory对象
Proxy proxy = new Proxy(Proxy.Type.HTTP,new InetSocketAddress("10.38.194.30", 8080));
HttpsURLConnection httpsConn = (HttpsURLConnection) myURL.openConnection();
httpsConn.setRequestProperty( "Proxy-Authorization", "Basic " + new sun.misc.BASE64Encoder().encode("dajiang:Abcd1234".getBytes()) );
httpsConn.setSSLSocketFactory(ssf);
httpsConn.setHostnameVerifier(new TrustAnyHostnameVerifier());
// 以POST方式提交
httpsConn.setRequestMethod("POST");
// 设置连接输出
httpsConn.setDoInput(true);
httpsConn.setDoOutput(true);
// Post 请求不能使用缓存
httpsConn.setUseCaches(false);
httpsConn.setRequestProperty("Content-Type","application/xml");
// httpsConn.connect();

//获取输出流
OutputStream os = httpsConn.getOutputStream();
// // 设置输出流字符集
os.write(xmlContent.getBytes("UTF-8"));
os.flush();
os.close();

// 取得该连接的输入流，以读取响应内容
InputStreamReader insr = new InputStreamReader(httpsConn.getInputStream());
// 读取服务器的响应内容并显示
int respInt = insr.read();
while (respInt != -1) {
System.out.print((char) respInt);
respInt = insr.read();
}

}

/*
* 用于连接https使用
*/
private static class TrustAnyTrustManager implements X509TrustManager {
public void checkClientTrusted(X509Certificate[] chain, String authType)throws CertificateException {
}

public void checkServerTrusted(X509Certificate[] chain, String authType)throws CertificateException {
}

public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return new java.security.cert.X509Certificate[] {};
}

public void checkClientTrusted(java.security.cert.X509Certificate[] arg0, String arg1)
throws java.security.cert.CertificateException {
}

public void checkServerTrusted(java.security.cert.X509Certificate[] arg0, String arg1)
throws java.security.cert.CertificateException {
}
}

private static class TrustAnyHostnameVerifier implements HostnameVerifier {

public boolean verify(String hostname, SSLSession session) {
return true;
}
}

按这种方法，终于链接成功，大石头落地~！
