Class ConnectorServerFactoryBean

All Implemented Interfaces:
DisposableBean, FactoryBean<JMXConnectorServer>, InitializingBean

public class ConnectorServerFactoryBean extends MBeanRegistrationSupport implements FactoryBean<JMXConnectorServer>, InitializingBean, DisposableBean
FactoryBean that creates a JSR-160 JMXConnectorServer, optionally registers it with the MBeanServer, and then starts it.

The JMXConnectorServer can be started in a separate thread by setting the threaded property to true. You can configure this thread to be a daemon thread by setting the daemon property to true.

The JMXConnectorServer is correctly shut down when an instance of this class is destroyed on shutdown of the containing ApplicationContext.

    • setServiceUrl

      public void setServiceUrl(String serviceUrl)
      Set the service URL for the JMXConnectorServer.
    • setEnvironment

      public void setEnvironment(@Nullable Properties environment)
      Set the environment properties used to construct the JMXConnectorServer as java.util.Properties (String key/value pairs).
    • setEnvironmentMap

      public void setEnvironmentMap(@Nullable Map<String,?> environment)
      Set the environment properties used to construct the JMXConnector as a Map of String keys and arbitrary Object values.
    • setForwarder

      public void setForwarder(MBeanServerForwarder forwarder)
      Set an MBeanServerForwarder to be applied to the JMXConnectorServer.
    • setObjectName

      public void setObjectName(Object objectName) throws MalformedObjectNameException
      Set the ObjectName used to register the JMXConnectorServer itself with the MBeanServer, as ObjectName instance or as String.
      MalformedObjectNameException - if the ObjectName is malformed
    • setThreaded

      public void setThreaded(boolean threaded)
      Set whether the JMXConnectorServer should be started in a separate thread.
    • setDaemon

      public void setDaemon(boolean daemon)
      Set whether any threads started for the JMXConnectorServer should be started as daemon threads.
    • afterPropertiesSet

      public void afterPropertiesSet() throws JMException, IOException
      Start the connector server. If the threaded flag is set to true, the JMXConnectorServer will be started in a separate thread. If the daemon flag is set to true, that thread will be started as a daemon thread.
      Specified by:
      afterPropertiesSet in interface InitializingBean
      JMException - if a problem occurred when registering the connector server with the MBeanServer
      IOException - if there is a problem starting the connector server
    • getObject

      @Nullable public JMXConnectorServer getObject()
      Description copied from interface: FactoryBean
      Return an instance (possibly shared or independent) of the object managed by this factory.

      As with a BeanFactory, this allows support for both the Singleton and Prototype design pattern.

      If this FactoryBean is not fully initialized yet at the time of the call (for example because it is involved in a circular reference), throw a corresponding FactoryBeanNotInitializedException.

      As of Spring 2.0, FactoryBeans are allowed to return null objects. The factory will consider this as normal value to be used; it will not throw a FactoryBeanNotInitializedException in this case anymore. FactoryBean implementations are encouraged to throw FactoryBeanNotInitializedException themselves now, as appropriate.

      Specified by:
      getObject in interface FactoryBean<JMXConnectorServer>
      an instance of the bean (can be null)
      See Also:
    • getObjectType

      public Class<? extends JMXConnectorServer> getObjectType()
      Description copied from interface: FactoryBean
      Return the type of object that this FactoryBean creates, or null if not known in advance.

      This allows one to check for specific types of beans without instantiating objects, for example on autowiring.

      In the case of implementations that are creating a singleton object, this method should try to avoid singleton creation as far as possible; it should rather estimate the type in advance. For prototypes, returning a meaningful type here is advisable too.

      This method can be called before this FactoryBean has been fully initialized. It must not rely on state created during initialization; of course, it can still use such state if available.

      NOTE: Autowiring will simply ignore FactoryBeans that return null here. Therefore it is highly recommended to implement this method properly, using the current state of the FactoryBean.

      Specified by:
      getObjectType in interface FactoryBean<JMXConnectorServer>
      the type of object that this FactoryBean creates, or null if not known at the time of the call
      See Also:
    • isSingleton

      public boolean isSingleton()
      Description copied from interface: FactoryBean
      Is the object managed by this factory a singleton? That is, will FactoryBean.getObject() always return the same object (a reference that can be cached)?

      NOTE: If a FactoryBean indicates to hold a singleton object, the object returned from getObject() might get cached by the owning BeanFactory. Hence, do not return true unless the FactoryBean always exposes the same reference.

      The singleton status of the FactoryBean itself will generally be provided by the owning BeanFactory; usually, it has to be defined as singleton there.

      NOTE: This method returning false does not necessarily indicate that returned objects are independent instances. An implementation of the extended SmartFactoryBean interface may explicitly indicate independent instances through its SmartFactoryBean.isPrototype() method. Plain FactoryBean implementations which do not implement this extended interface are simply assumed to always return independent instances if the isSingleton() implementation returns false.

      The default implementation returns true, since a FactoryBean typically manages a singleton instance.

      Specified by:
      isSingleton in interface FactoryBean<JMXConnectorServer>
      whether the exposed object is a singleton

    • destroy

      public void destroy() throws IOException
      Stop the JMXConnectorServer managed by an instance of this class. Automatically called on ApplicationContext shutdown.
      Specified by:
      destroy in interface DisposableBean
      IOException - if there is an error stopping the connector server
