Direct Known Subclasses:

AnnotationMBeanExporter

public class MBeanExporter
extends MBeanRegistrationSupport
implements MBeanExportOperations, BeanClassLoaderAware, BeanFactoryAware, InitializingBean, DisposableBean

JMX exporter that allows for exposing any Spring-managed bean to a JMX MBeanServer, without the need to define any JMX-specific information in the bean classes.

If a bean implements one of the JMX management interfaces, MBeanExporter can simply register the MBean with the server through its autodetection process.

If a bean does not implement one of the JMX management interfaces, MBeanExporter will create the management information using the supplied MBeanInfoAssembler.

A list of MBeanExporterListeners can be registered via the listeners property, allowing application code to be notified of MBean registration and unregistration events.

This exporter is compatible with JMX 1.2 on Java 5 and above. As of Spring 2.5, it also autodetects and exports Java 6 MXBeans.

Since:

1.2

Method Detail

setBeans

public void setBeans(java.util.Map<java.lang.String,java.lang.Object> beans)

Supply a Map of beans to be registered with the JMX MBeanServer.

The String keys are the basis for the creation of JMX object names. By default, a JMX ObjectName will be created straight from the given key. This can be customized through specifying a custom NamingStrategy.

Both bean instances and bean names are allowed as values. Bean instances are typically linked in through bean references. Bean names will be resolved as beans in the current factory, respecting lazy-init markers (that is, not triggering initialization of such beans).

Parameters:

beans - Map with JMX names as keys and bean instances or bean names as values

See Also:

setNamingStrategy(org.springframework.jmx.export.naming.ObjectNamingStrategy), KeyNamingStrategy, ObjectName.ObjectName(String)

setAutodetect

public void setAutodetect(boolean autodetect)

Set whether to autodetect MBeans in the bean factory that this exporter runs in. Will also ask an AutodetectCapableMBeanInfoAssembler if available.

This feature is turned off by default. Explicitly specify true here to enable autodetection.

See Also:

setAssembler(org.springframework.jmx.export.assembler.MBeanInfoAssembler), AutodetectCapableMBeanInfoAssembler, isMBean(java.lang.Class)

setAutodetectMode

public void setAutodetectMode(int autodetectMode)

Set the autodetection mode to use.

Throws:

java.lang.IllegalArgumentException - if the supplied value is not one of the AUTODETECT_ constants

See Also:

setAutodetectModeName(String), AUTODETECT_ALL, AUTODETECT_ASSEMBLER, AUTODETECT_MBEAN, AUTODETECT_NONE

setAutodetectModeName

public void setAutodetectModeName(java.lang.String constantName)

Set the autodetection mode to use by name.

Throws:

java.lang.IllegalArgumentException - if the supplied value is not resolvable to one of the AUTODETECT_ constants or is null

See Also:

setAutodetectMode(int), AUTODETECT_ALL, AUTODETECT_ASSEMBLER, AUTODETECT_MBEAN, AUTODETECT_NONE

setAllowEagerInit

public void setAllowEagerInit(boolean allowEagerInit)

Specify whether to allow eager initialization of candidate beans when autodetecting MBeans in the Spring application context.

Default is "false", respecting lazy-init flags on bean definitions. Switch this to "true" in order to search lazy-init beans as well, including FactoryBean-produced objects that haven't been initialized yet.

setAssembler

public void setAssembler(MBeanInfoAssembler assembler)

Set the implementation of the MBeanInfoAssembler interface to use for this exporter. Default is a SimpleReflectiveMBeanInfoAssembler.

The passed-in assembler can optionally implement the AutodetectCapableMBeanInfoAssembler interface, which enables it to participate in the exporter's MBean autodetection process.

See Also:

SimpleReflectiveMBeanInfoAssembler, AutodetectCapableMBeanInfoAssembler, MetadataMBeanInfoAssembler, setAutodetect(boolean)

setNamingStrategy

public void setNamingStrategy(ObjectNamingStrategy namingStrategy)

Set the implementation of the ObjectNamingStrategy interface to use for this exporter. Default is a KeyNamingStrategy.

See Also:

KeyNamingStrategy, MetadataNamingStrategy

setListeners

public void setListeners(MBeanExporterListener[] listeners)

Set the MBeanExporterListeners that should be notified of MBean registration and unregistration events.

See Also:

MBeanExporterListener

setExcludedBeans

public void setExcludedBeans(java.lang.String[] excludedBeans)

Set the list of names for beans that should be excluded from autodetection.

setEnsureUniqueRuntimeObjectNames

public void setEnsureUniqueRuntimeObjectNames(boolean ensureUniqueRuntimeObjectNames)

Indicates whether Spring should ensure that ObjectNames generated by the configured ObjectNamingStrategy for runtime-registered MBeans (registerManagedResource(java.lang.Object)) should get modified: to ensure uniqueness for every instance of a managed Class.

The default value is true.

See Also:

registerManagedResource(java.lang.Object), JmxUtils.appendIdentityToObjectName(javax.management.ObjectName, Object)

setExposeManagedResourceClassLoader

public void setExposeManagedResourceClassLoader(boolean exposeManagedResourceClassLoader)

Indicates whether or not the managed resource should be exposed on the thread context ClassLoader before allowing any invocations on the MBean to occur.

The default value is true, exposing a SpringModelMBean which performs thread context ClassLoader management. Switch this flag off to expose a standard JMX RequiredModelMBean.

setNotificationListeners

public void setNotificationListeners(NotificationListenerBean[] notificationListeners)

Set the NotificationListenerBeans containing the NotificationListeners that will be registered with the MBeanServer.

See Also:

setNotificationListenerMappings(java.util.Map), NotificationListenerBean

setNotificationListenerMappings

public void setNotificationListenerMappings(java.util.Map<?,? extends javax.management.NotificationListener> listeners)

Set the NotificationListeners to register with the MBeanServer.

The key of each entry in the Map is a String representation of the ObjectName or the bean name of the MBean the listener should be registered for. Specifying an asterisk (*) for a key will cause the listener to be associated with all MBeans registered by this class at startup time.

The value of each entry is the NotificationListener to register. For more advanced options such as registering NotificationFilters and handback objects see setNotificationListeners(NotificationListenerBean[]).

setBeanClassLoader

public void setBeanClassLoader(java.lang.ClassLoader classLoader)

Description copied from interface: BeanClassLoaderAware

Callback that supplies the bean class loader to a bean instance.

Invoked after the population of normal bean properties but before an initialization callback such as InitializingBean's InitializingBean.afterPropertiesSet() method or a custom init-method.

Specified by:

setBeanClassLoader in interface BeanClassLoaderAware

Parameters:

classLoader - the owning class loader; may be null in which case a default ClassLoader must be used, for example the ClassLoader obtained via ClassUtils.getDefaultClassLoader()

setBeanFactory

public void setBeanFactory(BeanFactory beanFactory)

This callback is only required for resolution of bean names in the "beans" Map and for autodetection of MBeans (in the latter case, a ListableBeanFactory is required).

Specified by:

setBeanFactory in interface BeanFactoryAware

Parameters:

beanFactory - owning BeanFactory (never null). The bean can immediately call methods on the factory.

See Also:

setBeans(java.util.Map<java.lang.String, java.lang.Object>), setAutodetect(boolean)

afterPropertiesSet

public void afterPropertiesSet()

Start bean registration automatically when deployed in an ApplicationContext.

Specified by:

afterPropertiesSet in interface InitializingBean

See Also:

registerBeans()

destroy

public void destroy()

Unregisters all beans that this exported has exposed via JMX when the enclosing ApplicationContext is destroyed.

Specified by:

destroy in interface DisposableBean

registerManagedResource

public javax.management.ObjectName registerManagedResource(java.lang.Object managedResource)
                                                    throws MBeanExportException

Description copied from interface: MBeanExportOperations

Register the supplied resource with JMX. If the resource is not a valid MBean already, Spring will generate a management interface for it. The exact interface generated will depend on the implementation and its configuration. This call also generates an ObjectName for the managed resource and returns this to the caller.

Specified by:

registerManagedResource in interface MBeanExportOperations

Parameters:

managedResource - the resource to expose via JMX

Returns:

the ObjectName under which the resource was exposed

Throws:

MBeanExportException - if Spring is unable to generate an ObjectName or register the MBean

registerManagedResource

public void registerManagedResource(java.lang.Object managedResource,
                           javax.management.ObjectName objectName)
                             throws MBeanExportException

Description copied from interface: MBeanExportOperations

Register the supplied resource with JMX. If the resource is not a valid MBean already, Spring will generate a management interface for it. The exact interface generated will depend on the implementation and its configuration.

Specified by:

registerManagedResource in interface MBeanExportOperations

Parameters:

managedResource - the resource to expose via JMX

objectName - the ObjectName under which to expose the resource

Throws:

MBeanExportException - if Spring is unable to register the MBean

unregisterManagedResource

public void unregisterManagedResource(javax.management.ObjectName objectName)

Description copied from interface: MBeanExportOperations

Remove the specified MBean from the underlying MBeanServer registry.

Specified by:

unregisterManagedResource in interface MBeanExportOperations

Parameters:

objectName - the ObjectName of the resource to remove

registerBeans

protected void registerBeans()

Registers the defined beans with the MBeanServer.

Each bean is exposed to the MBeanServer via a ModelMBean. The actual implemetation of the ModelMBean interface used depends on the implementation of the ModelMBeanProvider interface that is configured. By default the RequiredModelMBean class that is supplied with all JMX implementations is used.

The management interface produced for each bean is dependent on the MBeanInfoAssembler implementation being used. The ObjectName given to each bean is dependent on the implementation of the ObjectNamingStrategy interface being used.

isBeanDefinitionLazyInit

protected boolean isBeanDefinitionLazyInit(ListableBeanFactory beanFactory,
                               java.lang.String beanName)

Return whether the specified bean definition should be considered as lazy-init.

Parameters:

beanFactory - the bean factory that is supposed to contain the bean definition

beanName - the name of the bean to check

See Also:

ConfigurableListableBeanFactory.getBeanDefinition(java.lang.String), BeanDefinition.isLazyInit()

registerBeanNameOrInstance

protected javax.management.ObjectName registerBeanNameOrInstance(java.lang.Object mapValue,
                                                     java.lang.String beanKey)
                                                          throws MBeanExportException

Registers an individual bean with the MBeanServer.

This method is responsible for deciding how a bean should be exposed to the MBeanServer. Specifically, if the supplied mapValue is the name of a bean that is configured for lazy initialization, then a proxy to the resource is registered with the MBeanServer so that the the lazy load behavior is honored. If the bean is already an MBean then it will be registered directly with the MBeanServer without any intervention. For all other beans or bean names, the resource itself is registered with the MBeanServer directly.

Parameters:

mapValue - the value configured for this bean in the beans map; may be either the String name of a bean, or the bean itself

beanKey - the key associated with this bean in the beans map

Returns:

the ObjectName under which the resource was registered

Throws:

MBeanExportException - if the export failed

Invoked when using an AutodetectCapableMBeanInfoAssembler. Gives the assembler the opportunity to add additional beans from the BeanFactory to the list of beans to be exposed via JMX.

This implementation prevents a bean from being added to the list automatically if it has already been added manually, and it prevents certain internal classes from being registered automatically.

autodetectMBeans

private void autodetectMBeans()

Attempts to detect any beans defined in the ApplicationContext that are valid MBeans and registers them automatically with the MBeanServer.

autodetect

private void autodetect(MBeanExporter.AutodetectCallback callback)

Performs the actual autodetection process, delegating to an AutodetectCallback instance to vote on the inclusion of a given bean.

Parameters:

callback - the AutodetectCallback to use when deciding whether to include a bean or not

isExcluded

private boolean isExcluded(java.lang.String beanName)

Indicates whether or not a particular bean name is present in the excluded beans list.

isBeanDefinitionAbstract

private boolean isBeanDefinitionAbstract(ListableBeanFactory beanFactory,
                               java.lang.String beanName)

Return whether the specified bean definition should be considered as abstract.

injectNotificationPublisherIfNecessary

private void injectNotificationPublisherIfNecessary(java.lang.Object managedResource,
                                          javax.management.modelmbean.ModelMBean modelMBean,
                                          javax.management.ObjectName objectName)

If the supplied managed resource implements the NotificationPublisherAware an instance of NotificationPublisher is injected.

registerNotificationListeners

private void registerNotificationListeners()
                                    throws MBeanExportException

Register the configured NotificationListeners with the MBeanServer.

Throws:

MBeanExportException

unregisterNotificationListeners

private void unregisterNotificationListeners()

Unregister the configured NotificationListeners from the MBeanServer.

onRegister

protected void onRegister(javax.management.ObjectName objectName)

Called when an MBean is registered. Notifies all registered MBeanExporterListeners of the registration event.

Please note that if an MBeanExporterListener throws a (runtime) exception when notified, this will essentially interrupt the notification process and any remaining listeners that have yet to be notified will not (obviously) receive the MBeanExporterListener.mbeanRegistered(javax.management.ObjectName) callback.

Overrides:

onRegister in class MBeanRegistrationSupport

Parameters:

objectName - the ObjectName of the registered MBean

onUnregister

protected void onUnregister(javax.management.ObjectName objectName)

Called when an MBean is unregistered. Notifies all registered MBeanExporterListeners of the unregistration event.

Please note that if an MBeanExporterListener throws a (runtime) exception when notified, this will essentially interrupt the notification process and any remaining listeners that have yet to be notified will not (obviously) receive the MBeanExporterListener.mbeanUnregistered(javax.management.ObjectName) callback.

Overrides:

onUnregister in class MBeanRegistrationSupport

Parameters:

objectName - the ObjectName of the unregistered MBean

notifyListenersOfRegistration

private void notifyListenersOfRegistration(javax.management.ObjectName objectName)

Notifies all registered MBeanExporterListeners of the registration of the MBean identified by the supplied ObjectName.

notifyListenersOfUnregistration

private void notifyListenersOfUnregistration(javax.management.ObjectName objectName)

Notifies all registered MBeanExporterListeners of the unregistration of the MBean identified by the supplied ObjectName.
