jmx - 如何将 JMX 集成到 tomcat 应用程序或我做错了什么？

Question

我尝试配置 JMX，但没有成功。我做了什么？

1. 创建类：

   public class JmxTestBean implements IJmxTestBean {
   
       private String name;
       private int age;
       private boolean isSuperman;
   
       public int getAge() {
           return age;
       }
   
       public void setAge(int age) {
           this.age = age;
       }
   
       public void setName(String name) {
           this.name = name;
       }
   
       public String getName() {
           return name;
       }
   
       public int add(int x, int y) {
           return x + y;
       }
   
       public void dontExposeMe() {
           throw new RuntimeException();
       }
   }
   

2. 之后，我在 spring 配置中添加了以下几行：

   <bean id="mbeanServer" class="org.springframework.jmx.support.MBeanServerFactoryBean"/>
   
   <bean id="exporter" class="org.springframework.jmx.export.MBeanExporter">
       <property name="beans">
           <map>
               <entry key="bean:name=testBean1" value-ref="testBean"/>
           </map>
       </property>
       <property name="server" ref="mbeanServer"/>
   </bean>    
   <bean id="testBean" class="com.db.gbs.jmx.simulator.JmxTestBean">
       <property name="name" value="TEST"/>
       <property name="age" value="100"/>
   </bean>
   

3. 作为最后一步，我尝试如下设置 env 变量：

   set CATALONA_OPTS="-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9010"
   

   并启动tomcat7：

   mvn jetty:run-exploded -Dorg.eclipse.jetty.server.Request.maxFormContentSize=100000000 
   

   使用 JConsole 尝试连接并收到以下错误：

   Could not connect to localhost:9010 : Failed to retrieve 
   RMIServer stub: javax.naming.ServiceUnavailableException 
   [Root exception is java.rmi.ConnectException: Connection 
   refused to host: localhost; nested exception is:         
   java.net.ConnectException: Connection refused: connect]
   Could not connect to localhost:9010. Make sure the JVM 
   is running and that you are using the correct protocol 
   in the Service URL service:jmx:rmi:///jndi/rmi://localhost:9010/jmxrmi).
   

我做错了什么？
