/**
* {@code AbstractReflectiveMBeanInfoAssembler} subclass that allows
* method names to be explicitly excluded as MBean operations and attributes.
*
* Any method not explicitly excluded from the management interface will be exposed to
* JMX. JavaBean getters and setters will automatically be exposed as JMX attributes.
*
*
You can supply an array of method names via the {@code ignoredMethods}
* property. If you have multiple beans and you wish each bean to use a different
* set of method names, then you can map bean keys (that is the name used to pass
* the bean to the {@code MBeanExporter}) to a list of method names using the
* {@code ignoredMethodMappings} property.
*
*
If you specify values for both {@code ignoredMethodMappings} and
* {@code ignoredMethods}, Spring will attempt to find method names in the
* mappings first. If no method names for the bean are found, it will use the
* method names defined by {@code ignoredMethods}.
