Java 在JMXJConsole中使用不带XML的Spring实现MBean

我想使用Spring注释创建Bean，而不需要任何XML配置。我有一些类似于

的公共类WebAppInitializer实现WebApplicationInitializer

，它加载所有应用程序上下文

我将bean作为一个类：

@ManagedResource(objectName = "myBean.example:name=MonitoringService")
@Component
public class MonitoringService implements IMonitoringService {

    public static final Logger LOG = LoggerFactory.getLogger(MonitoringService.class);

    private boolean isDbServicesEnabled = true;

    @ManagedAttribute(description = "DBServices configurator")
    public boolean isDbServicesEnabled() {
        return isDbServicesEnabled;
    }

    @ManagedAttribute(description = "DBServices configurator")
    public void setDbServicesEnabled(boolean dbServicesEnabled) {
        LOG.info("DBServices " + (isDbServicesEnabled ? "enabled" : "disabled"));
        isDbServicesEnabled = dbServicesEnabled;
    }

}

和简单的界面：

public interface IMonitoringService {

    public boolean isDbServicesEnabled();
    public void setDbServicesEnabled(boolean dbServicesEnabled);

}

我将它部署到GlassFish3服务器上，一切正常，但我看不到它是JConsole。 问题在哪里

我还使用SimonXbeanManager进行统计，它的包装器工作正常

我必须在MBeanServer中注册吗

这是SimonManager配置的一个类：

@Configuration
public class MonitoringConfiguration {

@Bean
public Manager simonManager() throws Exception {
    ManagerFactoryBean managerFactoryBean = new ManagerFactoryBean();
    Callback jmxRegisterCallback = new JmxRegisterCallback(mBeanServer(), "myBean.example");
    managerFactoryBean.setCallbacks(Lists.newArrayList(jmxRegisterCallback));
    return managerFactoryBean.getObject();
}

@Bean
public SimonManagerMXBeanWrapper simonManagerMXBean() throws Exception {
    return new WebApplicationSimonManagerMXBeanWrapper(new SimonManagerMXBeanImpl(simonManager()));
}

@Bean
public MBeanServer mBeanServer() {
    MBeanServerFactoryBean mBeanServerFactoryBean = new MBeanServerFactoryBean();
    mBeanServerFactoryBean.setLocateExistingServerIfPossible(true);
    mBeanServerFactoryBean.afterPropertiesSet();
    return mBeanServerFactoryBean.getObject();
}

@Bean
public AnnotationMBeanExporter annotationMBeanExporter() {
    return new AnnotationMBeanExporter();
}

@ManagedResource(objectName = "myBean.example:name=SimonManager")
private class WebApplicationSimonManagerMXBeanWrapper extends SimonManagerMXBeanWrapper                  {

    public WebApplicationSimonManagerMXBeanWrapper(SimonManagerMXBean delegate) {
        super(delegate);
    }
}

以及加载应用程序上下文的类：

public class WebAppInitializer implements WebApplicationInitializer {

String[] locations = new String[] {
    "myBean.example"
};

public void onStartup(ServletContext container) throws ServletException {

    AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
    rootContext.register(
        RootContextConfig.class
    );
    rootContext.scan(locations);
    rootContext.refresh();

    container.addListener(new RequestContextListener());
    container.addListener(new ContextLoaderListener(rootContext));

    AnnotationConfigWebApplicationContext dispatcherContext = new AnnotationConfigWebApplicationContext();
    dispatcherContext.register(WebAppConfig.class);

    ServletRegistration.Dynamic dispatcher = container.addServlet(
        "dispatcher", new DispatcherServlet(dispatcherContext)
    );

    dispatcher.setLoadOnStartup(1);
    dispatcher.addMapping("/");

    createSimonWebConsole(container);
}

private void createSimonWebConsole(ServletContext container) {
    ServletRegistration.Dynamic dn =
        container.addServlet("simon-webconsole", new SimonConsoleServlet());
    dn.setInitParameter("url-prefix", "/javasimon-console");
    dn.addMapping("/javasimon-console/*");
}

}

好的，我想，我必须添加

@ComponentScan

注释，并使用

“myBean.example”

名称空间将其添加到类

监视配置

。现在我可以在JConsole中配置我的服务了
