java – 在spring中连接到JMX服务器抛出异常！

发布时间：2020-12-15 00:52:12 所属栏目：Java 来源：网络整理
导读：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.TCP
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弹簧配置：

    </bean>
</beans>

我认为jconsole不想连接到这个jmx服务器的错误是什么？ jmx url最后测试的是什么意思？我只是在教程中看到它,所以我在我的网址中写了相同的内容.

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

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异常)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发生了.

这个问题可能在配置中吗？有人可以验证我的配置是否正确？

编辑3：
每当我启动应用程序时,我都会得到这个.我猜这就是问题所在.它发生在服务器和我的机器上..

解决方法

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
