JMX代码编写

public class Controller implements ControllerMBean{
  private boolean forbiddenBrand = false;
  @Override
  public boolean isForbiddenBrand() {
    return forbiddenBrand;
  }
  @Override
  public void setForbiddenBrand(boolean forbiddenBrand) {
    this.forbiddenBrand = forbiddenBrand;
  }
  @Override
  public String status() {
    // TODO Auto-generated method stub
    return null;
  }
  @Override
  public void start() {
    // TODO Auto-generated method stub
    
  }
  @Override
  public void stop() {
    // TODO Auto-generated method stub
    
  }
}

Controller ，ControllerMBean 类名称不能修改，必须固定

public interface ControllerMBean {  
    public boolean isForbiddenBrand();
    public void setForbiddenBrand(boolean forbiddenBrand);  
      
    //操作  
    /** 
     * 获取当前信息 
     * @return 
     */  
    public String status();  
    public void start();  
    public void stop();  
      
}  

动态修改BrandPackageValidator.FORBIDDEN_BRAND字段

public class JmxExecutor {
  /**
   * 默认生成的该类的LOG记录器，使用slf4j组件。避免产生编译警告，使用protected修饰符。
   */
  protected final static Logger LOG = LoggerFactory.getLogger(JmxExecutor.class);
  private final static ControllerMBean controller = new Controller();
  static {
    Executors.newScheduledThreadPool(1).scheduleAtFixedRate(new Runnable() {
      @Override
      public void run() {
        BrandPackageValidator.FORBIDDEN_BRAND = controller.isForbiddenBrand();
      }
    }, 2, 5, TimeUnit.SECONDS);
  }
  public void executor() {
    // 获得MBeanServer实例
    MBeanServer mbs = ManagementFactory.getPlatformMBeanServer();
    try {
      mbs.registerMBean(controller, new ObjectName("apiJmx:name=controller"));
      // 创建适配器，用于能够通过浏览器访问MBean
      HtmlAdaptorServer adapter = new HtmlAdaptorServer();
      adapter.setPort(9797);
      mbs.registerMBean(adapter, new ObjectName("apiJmx:name=htmladapter,port=9797"));
      adapter.start();
    } catch (Exception e) {
      LOG.error("jxm运行出错", e);
    }
  }
}
