这是我的代码,用于根据上下文读取活动会话

尝试{

字符串serviceUrl =“ service:jmx:rmi:/// jndi / rmi:// localhost:9001 / jmxrmi”;

JMXServiceURL jmxServiceUrl =新的JMXServiceURL(serviceUrl);

JMXConnector jmxc = JMXConnectorFactory.connect(jmxServiceUrl,null);

MBeanServerConnection conn = jmxc.getMBeanServerConnection();

ObjectName名称=新的ObjectName(“ Catalina:type = Manager,context = / generateBill,host = localhost,port = 8080”);
System.out.println(“ sessionCounter generateBill”);
System.out.println(conn.getAttribute(name,“ sessionCounter”));;

ObjectName name2 = new ObjectName(“ Catalina:type = Manager,context = / generateBillService,host = localhost,port = 8080”);
System.out.println(“ sessionCounter generateBillService”);
System.out.println(conn.getAttribute(name2,“ sessionCounter”));
}
捕获(e例外){
e.printStackTrace();
}


但是我正在获取javax.management.InstanceNotFoundException。这个问题有什么解决方案?

最佳答案

ObjectName名称=新的ObjectName(“ Catalina:type = Manager,context = / examples,host = localhost”); System.out.println(conn.getAttribute(name,“ activeSessions”));

无需指定端口。
