私はリモートのjvmでThreadMXBeanで操作を呼び出そうとしています。 I動作たinvoke使用コードスニペットは、は、getRemote（）メソッドは、MBeanServerConnectionをリモートjvmのスレッドダンプをプログラムで作成する
IスタブのメソッドgetThreadInfo（）を呼び出すことはできませんを返すこと
bean = new ObjectName("java.lang:type=Threading");
memoryInfo = RemoteConnector.getRemote().getMBeanInfo(bean);
RemoteConnector.getRemote().getObjectInstance(bean);
MBeanOperationInfo [] mBeanAttributeInfos = memoryInfo.getOperations();
for(MBeanOperationInfo mBeanAttributeInfo : mBeanAttributeInfos){
System.out.println(mBeanAttributeInfo.getName());
}
long [] allThreadIds = (long [])RemoteConnector.getRemote().getAttribute(bean,"AllThreadIds");
Object [] params = new Object[2];
int maxDepth = 100;
params[0] = allThreadIds;
params[1] = maxDepth;
String [] opSigs = {allThreadIds.getClass().getName(),"I"};
RemoteConnector.getRemote().invoke(bean,"getThreadInfo",params,opSigs);
注以下です。私はこのメッセージに
2016-05-05 00:17:37 ERROR ThreadDumpCreator:67 - Operation getThreadInfo exists but not with this signature: ([J, I)
を取得し、私はこの問題を解決してください:)
以下ています私は、リモートのMBeanServer

private static MBeanServerConnection remote = null;

//for passing credentials for password
Map<String, String[]> env = new HashMap<String, String[]>();
String[] credentials = {"admin", "admin"};
env.put(JMXConnector.CREDENTIALS, credentials);
connector = JMXConnectorFactory.connect(target, env);
remote = connector.getMBeanServerConnection();
}catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
public static MBeanServerConnection getRemote() {
return remote;
}
public static void setRemote(MBeanServerConnection remote) {
RemoteConnector.remote = remote;
}
public static void closeConnection() throws IOException {
if(connector != null){
connector.close();
}
}
