## org.springframework.jmx.export.naming
Class MetadataNamingStrategy

    java.lang.Object
      org.springframework.jmx.export.naming.MetadataNamingStrategy

All Implemented Interfaces:
  InitializingBean, ObjectNamingStrategy

    public class MetadataNamingStrategy

extends Object
implements ObjectNamingStrategy, InitializingBean

An implementation of the `ObjectNamingStrategy` interface that reads the `ObjectName` from the source-level metadata. Falls back to the bean key (bean name) if no `ObjectName` can be found in source-level metadata.

Uses the `JmxAttributeSource` strategy interface, so that metadata can be read using any supported implementation. Out of the box, two strategies are included:

- `AttributesJmxAttributeSource`, for Commons Attributes
- `AnnotationJmxAttributeSource`, for JDK 1.5+ annotations

Since:
  1.2

Constructor Summary
`MetadataNamingStrategy()` Create a new `MetadataNamingStrategy`which needs to be configured through the `setAttributeSource(org.springframework.jmx.export.metadata.JmxAttributeSource)` method.``
`MetadataNamingStrategy(JmxAttributeSource attributeSource)` Create a new `MetadataNamingStrategy`for the given `JmxAttributeSource`.``

Method Summary
`void` `afterPropertiesSet()` Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).
`ObjectName` `getObjectName(Object managedBean, String beanKey)` Reads the `ObjectName` from the source-level metadata associated with the managed resource's `Class`.
`void` `setAttributeSource(JmxAttributeSource attributeSource)` Set the implementation of the `JmxAttributeSource` interface to use when reading the source-level metadata.
`void` `setDefaultDomain(String defaultDomain)` Specify the default domain to be used for generating ObjectNames when no source-level metadata has been specified.

Constructor Detail

### MetadataNamingStrategy

    public MetadataNamingStrategy()

  Create a new `MetadataNamingStrategy`which needs to be configured through the `setAttributeSource(org.springframework.jmx.export.metadata.JmxAttributeSource)` method.

  ``

### MetadataNamingStrategy

    public MetadataNamingStrategy(JmxAttributeSource attributeSource)

  Create a new `MetadataNamingStrategy`for the given `JmxAttributeSource`.

  Parameters:
    `attributeSource` - the JmxAttributeSource to use
  ``

Method Detail

### setAttributeSource

    public void setAttributeSource(JmxAttributeSource attributeSource)

  Set the implementation of the `JmxAttributeSource` interface to use when reading the source-level metadata.

### setDefaultDomain

    public void setDefaultDomain(String defaultDomain)

  Specify the default domain to be used for generating ObjectNames when no source-level metadata has been specified.

  The default is to use the domain specified in the bean name (if the bean name follows the JMX ObjectName syntax); else, the package name of the managed bean class.

### afterPropertiesSet

    public void afterPropertiesSet()

  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`

### getObjectName

    public ObjectName getObjectName(Object managedBean,
                                    String beanKey)
                             throws MalformedObjectNameException

  Reads the `ObjectName` from the source-level metadata associated with the managed resource's `Class`.

  Specified by:
    `getObjectName` in interface `ObjectNamingStrategy`
  Parameters:
    `managedBean` - the bean that will be exposed under the returned `ObjectName`
    `beanKey` - the key associated with this bean in the beans map passed to the `MBeanExporter`
  Returns:
    the `ObjectName` instance
  Throws:
    `MalformedObjectNameException` - if the resulting `ObjectName` is invalid
