通过Jconsole和Mbeans两种方式获取Tomcat核心线程参数

首先配置jmx参数（以下配置为不用密码登录的）：

-Dcom.sun.management.jmxremote.port=8004 
    -Dcom.sun.management.jmxremote.rmi.port=8004 
    -Dcom.sun.management.jmxremote.ssl=false 
    -Dcom.sun.management.jmxremote.authenticate=false

接下来可以自主选择Jconsole来获取tomcat核心参数，其中本地进程，在本地启动tomcat后可双击选择；远程进程根据是否设置用户名和 密码来设置（比较简单、自己查下，不再赘述）：

方法二：网上资料比较少，直接上代码：

// tomcat监控Mbeans
    try {
        final MBeanServer server = ManagementFactory.getPlatformMBeanServer();
        Set<ObjectName> names = server.queryNames(new ObjectName("Tomcat:type=ThreadPool,*"), null);
        if (names != null && !CollectionUtils.isEmpty(names)) {
            for (final ObjectName name : names) {
                System.out.print(server.getAttribute(name, "acceptCount"));
                System.out.print(server.getAttribute(name, "maxConnections"));
                System.out.print(server.getAttribute(name, "currentThreadCount"));
               System.out.print(server.getAttribute(name, "currentThreadsBusy"));
               
            }
        }
    }catch (Exception e) {
        logger.error("get_tomcatMonitor_error: ", e.getMessage());
    }
