AbstractReflectiveMBeanInfoAssembler

public abstract class AbstractMBeanInfoAssembler
extends Object
implements MBeanInfoAssembler

Abstract implementation of the MBeanInfoAssembler interface that encapsulates the creation of a ModelMBeanInfo instance but delegates the creation of metadata to subclasses.

This class offers two flavors of Class extraction from a managed bean instance: getTargetClass(java.lang.Object), extracting the target class behind any kind of AOP proxy, and getClassToExpose(java.lang.Object), returning the class or interface that will be searched for annotations and exposed to the JMX runtime.

方法详细资料

getMBeanInfo

public ModelMBeanInfo getMBeanInfo(Object managedBean,
                                   String beanKey)
                            throws JMException

Create an instance of the ModelMBeanInfoSupport class supplied with all JMX implementations and populates the metadata through calls to the subclass.

指定者:

getMBeanInfo 在接口中 MBeanInfoAssembler

参数:

managedBean - the bean that will be exposed (might be an AOP proxy)

beanKey - the key associated with the managed bean

返回:

the populated ModelMBeanInfo instance

抛出:

JMException - in case of errors

另请参阅:

getDescription(Object, String), getAttributeInfo(Object, String), getConstructorInfo(Object, String), getOperationInfo(Object, String), getNotificationInfo(Object, String), populateMBeanDescriptor(javax.management.Descriptor, Object, String)

checkManagedBean

protected void checkManagedBean(Object managedBean)
                         throws IllegalArgumentException

Check the given bean instance, throwing an IllegalArgumentException if it is not eligible for exposure with this assembler.

Default implementation is empty, accepting every bean instance.

参数:

managedBean - the bean that will be exposed (might be an AOP proxy)

抛出:

IllegalArgumentException - the bean is not valid for exposure

getTargetClass

protected Class<?> getTargetClass(Object managedBean)

Return the actual bean class of the given bean instance. This is the class exposed to description-style JMX properties.

Default implementation returns the target class for an AOP proxy, and the plain bean class else.

参数:

managedBean - the bean instance (might be an AOP proxy)

返回:

the bean class to expose

另请参阅:

AopUtils.getTargetClass(Object)

getClassToExpose

protected Class<?> getClassToExpose(Object managedBean)

Return the class or interface to expose for the given bean. This is the class that will be searched for attributes and operations (for example, checked for annotations).

参数:

managedBean - the bean instance (might be an AOP proxy)

返回:

the bean class to expose

另请参阅:

JmxUtils.getClassToExpose(Object)

getClassToExpose

protected Class<?> getClassToExpose(Class<?> beanClass)

Return the class or interface to expose for the given bean class. This is the class that will be searched for attributes and operations

参数:

beanClass - the bean class (might be an AOP proxy class)

返回:

the bean class to expose

另请参阅:

JmxUtils.getClassToExpose(Class)

getClassName

protected String getClassName(Object managedBean,
                              String beanKey)
                       throws JMException

Get the class name of the MBean resource.

Default implementation returns a simple description for the MBean based on the class name.

参数:

managedBean - the bean instance (might be an AOP proxy)

beanKey - the key associated with the MBean in the beans map of the MBeanExporter

返回:

the MBean description

抛出:

JMException - in case of errors

getDescription

protected String getDescription(Object managedBean,
                                String beanKey)
                         throws JMException

Get the description of the MBean resource.

Default implementation returns a simple description for the MBean based on the class name.

参数:

managedBean - the bean instance (might be an AOP proxy)

beanKey - the key associated with the MBean in the beans map of the MBeanExporter

抛出:

JMException - in case of errors

populateMBeanDescriptor

protected void populateMBeanDescriptor(Descriptor descriptor,
                                       Object managedBean,

                                throws JMException

Called after the ModelMBeanInfo instance has been constructed but before it is passed to the MBeanExporter.
