Class MBeanServerConnectionFactoryBean

java.lang.Object
  extended by org.springframework.jmx.support.MBeanServerConnectionFactoryBean
All Implemented Interfaces:
DisposableBean, FactoryBean, InitializingBean

public class MBeanServerConnectionFactoryBean
extends Object
implements FactoryBean, InitializingBean, DisposableBean

FactoryBean implementation that creates an MBeanServerConnection to a remote MBeanServer exposed via a JMXServerConnector. Exposes the MBeanServer for bean references.

Constructor Detail

MBeanServerConnectionFactoryBean

public MBeanServerConnectionFactoryBean()
Method Detail

setServiceUrl

public void setServiceUrl(String url)
                   throws MalformedURLException
Set the service URL of the remote MBeanServer.

Throws:
MalformedURLException

setEnvironment

public void setEnvironment(Properties environment)
Set the environment properties used to construct the JMXConnector as java.util.Properties (String key/value pairs).


setEnvironmentMap

public void setEnvironmentMap(Map environment)
Set the environment properties used to construct the JMXConnector as a Map of String keys and arbitrary Object values.


setConnectOnStartup

public void setConnectOnStartup(boolean connectOnStartup)
Set whether to connect to the server on startup. Default is "true".

Can be turned off to allow for late start of the JMX server. In this case, the JMX connector will be fetched on first access.


afterPropertiesSet

public void afterPropertiesSet()
                        throws IOException
Creates a JMXConnector for the given settings and exposes the associated MBeanServerConnection.

Specified by:
afterPropertiesSet in interface InitializingBean
Throws:
IOException

getObject

public Object 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 method returns null, the factory will consider the FactoryBean as not fully initialized and throw a corresponding FactoryBeanNotInitializedException.

Specified by:
getObject in interface FactoryBean
Returns:
an instance of the bean (should not be null; a null value will be considered as an indication of incomplete initialization)
See Also:
FactoryBeanNotInitializedException

getObjectType

public Class getObjectType()
Description copied from interface: FactoryBean
Return the type of object that this FactoryBean creates, or null if not known in advance. This allows to check for specific types of beans without instantiating objects, for example on autowiring.

For a singleton, this 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
Returns:
the type of object that this FactoryBean creates, or null if not known at the time of the call

ListableBeanFactory.getBeansOfType(java.lang.Class)

isSingleton

public boolean isSingleton()
Description copied from interface: FactoryBean
Is the bean managed by this factory a singleton or a prototype? That is, will 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.

Specified by:
isSingleton in interface FactoryBean
Returns:
if this bean is a singleton
See Also:
FactoryBean.getObject()

destroy

public void destroy()
             throws IOException
Closes the underlying JMXConnector.

Specified by:
destroy in interface DisposableBean
Throws:
IOException
