java - 连接到 Tomcat JMX 服务器失败

Question

未能连接到 Tomcat JMX 实例

好的，我现在卡住了 - 我正在尝试按如下方式使用 Tomcat 配置 JMX

$CATALINA_BASE/setenv.sh:

CATALINA_OPTS="-Dcom.sun.management.jmxremote.port=18070 -Dcom.sun.management.jmxremote.password.file=$CATALINA_BASE/conf/jmxremote.password -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=true -Dcom.sun.management.jmxremote.access.file=$CATALINA_BASE/conf/jmxremote.access"
export CATALINA_OPTS

$CATALINA_BASE/conf/jmxremote.password

    monitorRole monitorpass
    controlRole controlpass

$CATALINA_BASE/conf/jmxremote.access

    monitorRole readonly
    controlRole readwrite

我用来访问 Tomcat JMX 服务器的客户端工具与 Tomcat 实例在同一台机器上运行。当我启动 tomcat 时，我可以看到在端口 18070 上有东西在监听，但是当我尝试连接时，出现以下错误

    Exception in thread "main" java.lang.SecurityException: Authentication failed! Credentials required
            at com.sun.jmx.remote.security.JMXPluggableAuthenticator.authenticationFailure(JMXPluggableAuthenticator.java:193)
            at com.sun.jmx.remote.security.JMXPluggableAuthenticator.authenticate(JMXPluggableAuthenticator.java:145)
            at sun.management.jmxremote.ConnectorBootstrap$AccessFileCheckerAuthenticator.authenticate(ConnectorBootstrap.java:185)
            at javax.management.remote.rmi.RMIServerImpl.doNewClient(RMIServerImpl.java:213)

我使用以下代码连接

            try {
                url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://localhost:18070/jmxrmi");
                jmxc = JMXConnectorFactory.connect(url,null); 
                mbsc = jmxc.getMBeanServerConnection();             
            } catch (MalformedURLException e) {
                throw new Exception(methodName + ":" + e);
            } catch (IOException e) {
                throw new Exception(methodName + ":" + "Failed to connect to the Tomcat Server " + e);
            }

如果我将 com.sun.management.jmxremote.authenticate=true 设置为 false，它工作正常。除此之外，它只是失败了。客户端工具与 tomcat 实例在同一台机器上运行，因此防火墙应该没有任何问题。任何线索

这个

JMXServiceURL url = ...;
Map env = ...;
String[] creds = {"monitorRole", "mrpasswd"};
env.put(JMXConnector.CREDENTIALS, creds);
JMXConnector cc = JMXConnectorFactory.connect(url, env);
MBeanServerConnection mbsc = cc.getMBeanServerConnection();
