All Implemented Interfaces:
  BeanClassLoaderAware, InitializingBean, MBeanInfoAssembler

    public class InterfaceBasedMBeanInfoAssembler

extends AbstractConfigurableMBeanInfoAssembler
implements BeanClassLoaderAware, InitializingBean

Subclass of `AbstractReflectiveMBeanInfoAssembler` that allows for the management interface of a bean to be defined using arbitrary interfaces. Any methods or properties that are defined in those interfaces are exposed as MBean operations and attributes.

By default, this class votes on the inclusion of each operation or attribute based on the interfaces implemented by the bean class. However, you can supply an array of interfaces via the `managedInterfaces` property that will be used instead. If you have multiple beans and you wish each bean to use a different set of interfaces, then you can map bean keys (that is the name used to pass the bean to the `MBeanExporter`) to a list of interface names using the `interfaceMappings` property.

If you specify values for both `interfaceMappings` and `managedInterfaces`, Spring will attempt to find interfaces in the mappings first. If no interfaces for the bean are found, it will use the interfaces defined by `managedInterfaces`.

Constructor Detail

### InterfaceBasedMBeanInfoAssembler

    public InterfaceBasedMBeanInfoAssembler()

Method Detail

### setManagedInterfaces

    public void setManagedInterfaces(Class[] managedInterfaces)

  Set the array of interfaces to use for creating the management info. These interfaces will be used for a bean if no entry corresponding to that bean is found in the `interfaceMappings` property.

  Parameters:
    `managedInterfaces` - an array of classes indicating the interfaces to use. Each entry MUST be an interface.
  See Also:
    `setInterfaceMappings(java.util.Properties)`

### setInterfaceMappings

    public void setInterfaceMappings(Properties mappings)

  Set the mappings of bean keys to a comma-separated list of interface names. The property key should match the bean key and the property value should match the list of interface names. When searching for interfaces for a bean, Spring will check these mappings first.

  Parameters:
    `mappings` - the mappins of bean keys to interface names

### setBeanClassLoader

    public void setBeanClassLoader(ClassLoader beanClassLoader)

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

### 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`

### includeReadAttribute

    protected boolean includeReadAttribute(Method method,
                                           String beanKey)

  Check to see if the `Method` is declared in one of the configured interfaces and that it is public.

  Specified by:
    `includeReadAttribute` in class `AbstractReflectiveMBeanInfoAssembler`
  Parameters:
    `method` - the accessor `Method`.
    `beanKey` - the key associated with the MBean in the `beans` `Map`.
  Returns:
    `true` if the `Method` is declared in one of the configured interfaces, otherwise `false`.

### includeWriteAttribute

    protected boolean includeWriteAttribute(Method method,
                                            String beanKey)

  Check to see if the `Method` is declared in one of the configured interfaces and that it is public.

  Specified by:
    `includeWriteAttribute` in class `AbstractReflectiveMBeanInfoAssembler`
  Parameters:
    `method` - the mutator `Method`.
    `beanKey` - the key associated with the MBean in the `beans` `Map`.
  Returns:
    `true` if the `Method` is declared in one of the configured interfaces, otherwise `false`.

### includeOperation

    protected boolean includeOperation(Method method,
                                       String beanKey)

  Check to see if the `Method` is declared in one of the configured interfaces and that it is public.

  Specified by:
    `includeOperation` in class `AbstractReflectiveMBeanInfoAssembler`
  Parameters:
    `method` - the operation `Method`.
    `beanKey` - the key associated with the MBean in the `beans` `Map`.
  Returns:
    `true` if the `Method` is declared in one of the configured interfaces, otherwise `false`.
