在spring中连接到JMX服务器会引发exception！
所以当我尝试从jconsole连接到jmx时，我得到了这个exception：
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弹簧配置：
我认为jconsole不想连接到这个jmx服务器的错误是什么？ jmx url最后test的是什么意思？ 我只是在教程中看到它，所以我在我的url中写了相同的内容。
编辑1：当我在服务器上运行netstat -ntlp时我得到这个：tcp6 0 0 ::: 10099 ::: * LISTEN 10754 / java
10754是正确的java应用程序。 那是对的吗？ 运行telnet 。 。*。*在10099上我得到一条消息，它也连接到它。 所以我猜这不是服务器端的防火墙？
编辑2：好吧，我现在正在尝试（并且在服务器上也抛出exception）在我的本地环境（在Eclipse中）运行应用程序，我猜测它不是服务器问题，因为所有相同的事情都会发生。

这个问题可能在配置中吗？ 有人可以validation我的配置是否正确？
编辑3：每次启动应用程序时都会得到这个。 我猜这就是问题所在。 它发生在服务器和我的机器上..

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
正确的答案是在你的RMI bean上设置alwaysCreate，如下所示：
这可以防止bean尝试连接以查找现有的RMI注册表。
