## 9. JMX support

## 9.1. `@MBeanExport`

As an equivalent to Spring XML's `<context:mbean-export/>` element, JavaConfig provides the `@MBeanExport` annotation.

    /**
     * A performance monitor that implements a JMX MBean interface
     */
    public class PerformanceMonitor implements PerformanceMonitorMBean {
        public int getHitCount() {
            return hitCount;
        }
        // ...
    }

    public interface PerformanceMonitorMBean {
        int getHitCount();
        // ...
    }

    /**
     * A @Configuration class that wires up a PerformanceMonitor bean and ensures
     * it is registered with the local MBean server using @MBeanExport
     */
    @Configuration
    @MBeanExport
    public class Config {
        // declare the MBean class as a spring bean
        @Bean
        public PerformanceMonitor performanceMonitor() {
            return new PerformanceMonitor();
        }
    }

| Note
Like with `<context:mbean-export/>`, MBean classes can be defined in a number of ways - using traditional MBean interfaces as shown above, or with Spring's `@ManagedResource` and associated annotations, etc. See the core Spring Framework documentation on JMX support for details.
