public class MBeanProxyFactoryBean extends MBeanClientInterceptor implements FactoryBean<Object>, BeanClassLoaderAware, InitializingBean
Creates a proxy to a managed resource running either locally or remotely. The "proxyInterface" property defines the interface that the generated proxy is supposed to implement. This interface should define methods and properties that correspond to operations and attributes in the management interface of the resource you wish to proxy.There is no need for the managed resource to implement the proxy interface, although you may find it convenient to do. It is not required that every operation and attribute in the management interface is matched by a corresponding property or method in the proxy interface.
Attempting to invoke or access any method or property on the proxy interface that does not correspond to the management interface will lead to an

方法详细资料
setProxyInterface
public void setProxyInterface(Class<?> proxyInterface)
Set the interface that the generated proxy will implement.This will usually be a management interface that matches the target MBean, exposing bean property setters and getters for MBean attributes and conventional Java methods for MBean operations.
setBeanClassLoader
public void setBeanClassLoader(ClassLoader classLoader)
从接口复制的说明:BeanClassLoaderAware
Callback that supplies the beanclass 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.- 指定者:
setBeanClassLoader
在接口中BeanClassLoaderAware
- 覆盖:
setBeanClassLoader
在类中MBeanClientInterceptor
- 参数:
classLoader
- the owning class loader
afterPropertiesSet
public void afterPropertiesSet() throws MBeanServerNotFoundException, MBeanInfoRetrievalException
Checks that theproxyInterface
has been specified and then generates the proxy for the target MBean.
getObject
@Nullable public Object getObject()
从接口复制的说明: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 FactoryBean is not fully initialized yet at the time of the call (for example because it is involved in a circular reference), throw a corresponding
FactoryBeanNotInitializedException
.As of Spring 2.0, FactoryBeans are allowed to return
null
objects. The factory will consider this as normal value to be used; it will not throw a FactoryBeanNotInitializedException in this case anymore. FactoryBean implementations are encouraged to throw FactoryBeanNotInitializedException themselves now, as appropriate.- 指定者:
getObject
在接口中FactoryBean<Object>
- 返回:
- an instance of the bean (can be
null
) - 另请参阅:
FactoryBeanNotInitializedException
getObjectType
public Class<?> getObjectType()
从接口复制的说明:FactoryBean
Return the type of object that this FactoryBean creates, ornull
if not known in advance.This allows one to check for specific types of beans without instantiating objects, for example on autowiring.
In the case of implementations that are creating a singleton object, this method 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.- 指定者:
getObjectType
在接口中FactoryBean<Object>
- 返回:
- the type of object that this FactoryBean creates, or
null
if not known at the time of the call - 另请参阅:
ListableBeanFactory.getBeansOfType(java.lang.Class<T>)
isSingleton
public boolean isSingleton()
从接口复制的说明:FactoryBean
Is the object managed by this factory a singleton? That is, willFactoryBean.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 returntrue
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.
NOTE: This method returning
false
does not necessarily indicate that returned objects are independent instances. An implementation of the extendedSmartFactoryBean
interface may explicitly indicate independent instances through itsSmartFactoryBean.isPrototype()
method. PlainFactoryBean
implementations which do not implement this extended interface are simply assumed to always return independent instances if theisSingleton()
implementation returnsfalse
.The default implementation returns
true
, since aFactoryBean
typically manages a singleton instance.- 指定者:
isSingleton
在接口中FactoryBean<Object>
- 返回:
- whether the exposed object is a singleton
