[5]AMQP(高级消息队列协议) ----如何创建自己的SSLContext对象

在[4]AMQP(高级消息队列协议) ----改造QPID JMS-0.9 API 对 SSLContext的
支持(http://blog.csdn.net/chancein007/article/category/6294435)的一文中，提到了如何让QPID JMS 0.9 Java对自定义的SSLContext的支持，那么该如何测试呢？其实测试的核心就是如何创建SSLContext对象。

假设我们的KeyStore和TrustStore的相关证书都保存在了相应的JKS文件里面

String truststore_File_Path="D:/QpidSSL/clientts.jks";
String truststore_password="123456";
String keystore_File_Path="D:/QpidSSL/clientks.jks";
String keystore_Password="123456";
System.setProperty("javax.net.ssl.keyStore",keystore_File_Path);
System.setProperty("javax.net.ssl.keyStorePassword",keystore_Password);
System.setProperty("javax.net.ssl.trustStore",truststore_File_Path);
System.setProperty("javax.net.ssl.trustStorePassword",truststore_password);

那么该如何创建SSLContext的对象呢？
#1 首先大家来看一下客户端API的调用

String truststore_File_Path="D:/QpidSSL/clientts.jks";
String truststore_password="123456";
String keystore_File_Path="D:/QpidSSL/clientks.jks";
String keystore_Password="123456";
String aliasPassword="123456";
SSLFactory sslFactory=new SSLFactory(keystore_File_Path,keystore_Password,truststore_File_Path,truststore_password,aliasPassword);
try {
SSLContext sslContext=sslFactory.buildSSLContext();
CustomTransportSupport.mapSSLContext.put("amqps://stevenGu:5674", sslContext);
} catch (UnrecoverableKeyException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (KeyManagementException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (KeyStoreException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (NoSuchAlgorithmException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (CertificateException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (FileNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}

#2 SSLFactory的代码如下
package com.test.amqp.ssl.sslcontext;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.security.KeyManagementException;
import java.security.KeyStore;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;
import java.security.UnrecoverableKeyException;
import java.security.cert.CertificateException;
import java.util.Arrays;

import javax.net.ssl.KeyManagerFactory;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManagerFactory;

public class SSLFactory {
private String keystorePath;
private String keystorePassword;
private String trustStorePath;
private String trustStorePassword;
private String aliasPassword;
public SSLFactory(String keystorePath,String keystorePassword,String trustStorePath,String trustStorePassword,String aliasPassword){
this.keystorePath=keystorePath;
this.keystorePassword=keystorePassword;
this.trustStorePath=trustStorePath;
this.trustStorePassword=trustStorePassword;
this.aliasPassword=aliasPassword;
}
private SSLContext getSSLContext() throws NoSuchAlgorithmException {
SSLContext c = null;

// pick the first protocol available, preferring TLSv1.2, then TLSv1,
// falling back to SSLv3 if running on an ancient/crippled JDK
for(String proto : Arrays.asList("TLSv1.2", "TLSv1", "SSLv3")) {
try {
c = SSLContext.getInstance(proto);
return c;
} catch (NoSuchAlgorithmException x) {
// keep trying
}
}
throw new NoSuchAlgorithmException();
}
public SSLContext buildSSLContext() throws KeyStoreException, NoSuchAlgorithmException, CertificateException, FileNotFoundException,
IOException, UnrecoverableKeyException, KeyManagementException{

KeyStore ks = KeyStore.getInstance("JKS");
ks.load(new FileInputStream(keystorePath), keystorePassword.toCharArray());
KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
kmf.init(ks, aliasPassword.toCharArray());

KeyStore tks = KeyStore.getInstance("JKS");
tks.load(new FileInputStream(trustStorePath), trustStorePassword.toCharArray());
TrustManagerFactory tmf = TrustManagerFactory.getInstance("SunX509");
tmf.init(tks);

SSLContext c = getSSLContext();
c.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);

return c;
}
}


是不是瞬间感觉高大上了，原来我们自己也能获得SSLContext的对象了。
