所以当我尝试从 jconsole 连接到 jmx 时，我得到了这个异常:

Caused by: java.rmi.ConnectException: Connection refused to host: 78.84.17.116; nested exception is: 
    java.net.ConnectException: Connection timed out: connect
    at sun.rmi.transport.tcp.TCPEndpoint.newSocket(TCPEndpoint.java:601)
    at sun.rmi.transport.tcp.TCPChannel.createConnection(TCPChannel.java:198)
    ...

我试图在 jconsole 中连接到这样的 url:service:jmx:rmi:///jndi/rmi://78.84.17.116:43030/test

我的 jmx Spring 配置:

jconsole 不想连接到这个 jmx 服务器，我可能做错了什么？ jmx url 末尾的 test 是什么意思？我刚刚在教程中看到它是这样的，所以我在我的 url 中写了同样的内容。

编辑 1: 当我在服务器上运行 netstat -ntlp 时，我得到了这个: tcp6 0 0:::10099:::* 听 10754/java

其中 10754 是正确的 Java 应用程序。那是对的吗？在 10099 上运行 telnet ..*.* 我收到一条消息，它也连接到它。所以我想这不是服务器端的防火墙？

编辑 2: 好吧，我现在正在尝试(下面的异常也在服务器上抛出)在我的本地环境(在 Eclipse 中)上运行应用程序，我猜这不是服务器问题，因为所有相同的事情都会发生。

问题可能出在配置上吗？有人可以验证我的配置是否正确吗？

编辑 3: 我每次启动应用程序时都会收到此信息。我想这就是问题所在。它发生在服务器和我的机器上..

最佳答案

尝试添加以下系统属性以禁用安全性:

 -Dcom.sun.management.jmxremote.authenticate=false
 -Dcom.sun.management.jmxremote.ssl=false 
 -Dcom.sun.management.jmxremote.port=39600
