Class WebLogicJndiMBeanServerFactoryBean

java.lang.Object
  org.springframework.jndi.JndiAccessor
      org.springframework.jndi.JndiLocatorSupport
          org.springframework.jmx.support.WebLogicJndiMBeanServerFactoryBean

All Implemented Interfaces:

FactoryBean, InitializingBean

---

public class WebLogicJndiMBeanServerFactoryBean
extends JndiLocatorSupport
implements FactoryBean, InitializingBean

FactoryBean that obtains the WebLogic MBeanServer instance through a WebLogic MBeanHome obtained via a JNDI lookup. By default, the server's local MBeanHome will be obtained.

Exposes the MBeanServer for bean references. This FactoryBean is a direct alternative to MBeanServerFactoryBean, which uses standard JMX 1.2 API to access the platform's MBeanServer.

Note: There is also a more general WebLogicMBeanServerFactoryBean for accessing any specified WebLogic MBeanServer, potentially a remote one.

Since:

1.2.6

Method Detail

setMbeanHomeName

public void setMbeanHomeName(String mbeanHomeName)

Specify the JNDI name of the WebLogic MBeanHome object to use for creating the JMX MBeanServer reference.

Default is MBeanHome.LOCAL_JNDI_NAME

weblogic.management.MBeanHome#LOCAL_JNDI_NAME

afterPropertiesSet

public void afterPropertiesSet()
                        throws MBeanServerNotFoundException

Description copied from interface: InitializingBean

Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).

This method allows the bean instance to perform initialization only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.

Specified by:

afterPropertiesSet in interface InitializingBean

Throws:

MBeanServerNotFoundException

---

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

See Also:

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

FactoryBean.getObject()
