使用SSL双向认证和JMXMP实现对系统状态的监控
在实际生产环境下，使用RMI实现JMX会受到来自防火墙的诸多限制，替代的方案就是使用JMXMP协议。核心代码实现如下：
JMX服务端：
final String protocol = "jmxmp";
final String host = "192.168.1.6";
final int port = 12345;
final String serverKeyStoreFile = appBase + "/config/jmxkey/server.keystore";
final String serverKeyStorePwd = "storepass";
final String serverKeyPwd = "keypass";
final String serverTrustKeyStoreFile = appBase + "/config/jmxkey/servertrust.keystore";
final String serverTrustKeyStorePwd = "truststorepass";
// 创建MBeanServer
MBeanServer mbs = ManagementFactory.getPlatformMBeanServer();
// 创建并注册MBean
final String domain = "app";
final String className = AppInfo.class.getName();
final String name = domain + ":" + "name=" + className;
final ObjectName objectName = ObjectName.getInstance(name);
mbs.createMBean(className, objectName);
// 创建SSLSocketFactory
KeyStore serverKeyStore = KeyStore.getInstance("JKS");
serverKeyStore.load(new FileInputStream(serverKeyStoreFile),
serverKeyStorePwd.toCharArray());
KeyStore serverTrustKeyStore = KeyStore.getInstance("JKS");
serverTrustKeyStore.load(new FileInputStream(serverTrustKeyStoreFile),
serverTrustKeyStorePwd.toCharArray());
KeyManagerFactory kmf = KeyManagerFactory
.getInstance(KeyManagerFactory.getDefaultAlgorithm());
kmf.init(serverKeyStore, serverKeyPwd.toCharArray());
TrustManagerFactory tmf = TrustManagerFactory
.getInstance(TrustManagerFactory.getDefaultAlgorithm());
tmf.init(serverTrustKeyStore);
SSLContext sslContext = SSLContext.getInstance("TLSv1");
sslContext.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);
SSLSocketFactory ssf = sslContext.getSocketFactory();
// 创建JMX服务器
Map<String, Object> env = new HashMap<>();
env.put("jmx.remote.profiles", "TLS");
env.put("jmx.remote.tls.socket.factory", ssf);
env.put("jmx.remote.tls.enabled.protocols", "TLSv1");
env.put("jmx.remote.tls.enabled.cipher.suites",
"SSL_RSA_WITH_3DES_EDE_CBC_SHA");
JMXServiceURL url = new JMXServiceURL(protocol, host, port);
JMXConnectorServer cs = JMXConnectorServerFactory
.newJMXConnectorServer(url, env, mbs);
cs.start();
JMX客户端：
final String protocol = "jmxmp";
final String host = "192.168.1.6";
final int port = 12345;
final String clientKeyStoreFile = appBase + "/config/jmxkey/client.keystore";
final String clientKeyStorePwd = "storepass";
final String foxclientKeyPwd = "keypass";
final String clientTrustKeyStoreFile = appBase + "/config/jmxkey/clienttrust.keystore";
final String clientTrustKeyStorePwd = "truststorepass";
// 创建SSLSocketFactory
KeyStore clientKeyStore = KeyStore.getInstance("JKS");
clientKeyStore.load(new FileInputStream(clientKeyStoreFile), clientKeyStorePwd.toCharArray());
KeyStore clientTrustKeyStore = KeyStore.getInstance("JKS");
clientTrustKeyStore.load(new FileInputStream(clientTrustKeyStoreFile), clientTrustKeyStorePwd.toCharArray());
KeyManagerFactory kmf = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
kmf.init(clientKeyStore, foxclientKeyPwd.toCharArray());
TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
tmf.init(clientTrustKeyStore);
SSLContext sslContext = SSLContext.getInstance("TLSv1");
sslContext.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);
SSLSocketFactory ssf = sslContext.getSocketFactory();
// 创建JMX客户端
HashMap<String, Object> env = new HashMap<>();
env.put("jmx.remote.profiles", "TLS");
env.put("jmx.remote.tls.socket.factory", ssf);
env.put("jmx.remote.tls.enabled.protocols", "TLSv1");
env.put("jmx.remote.tls.enabled.cipher.suites",
"SSL_RSA_WITH_3DES_EDE_CBC_SHA");
JMXServiceURL url = new JMXServiceURL(protocol, host, port);
JMXConnector jmxc = JMXConnectorFactory.connect(url, env);
MBeanServerConnection mbsc = jmxc.getMBeanServerConnection();
// 获取所有的域
final String domains[] = mbsc.getDomains();
for (int i = 0; i < domains.length; i++)
{
System.out.println("Domain[" + i + "] = " + domains[i]);
}
// 调用方法
final String domain = "app";
final String className = AppInfo.class.getName();
final String name = domain + ":" + "name=" + className;
final ObjectName objectName = ObjectName.getInstance(name);
AppInfoMXBean appInfo = JMX.newMBeanProxy(
mbsc, objectName, AppInfoMXBean.class);
System.out.println(appInfo.getAppName());
System.out.println(appInfo.getAppVersion());
jmxc.close();
