  返回:

  the MBeanServer if found

  抛出:

  MBeanServerNotFoundException - if no MBeanServer could be found

• locateMBeanServer

  public static MBeanServer locateMBeanServer​(@Nullable
                                              String agentId)
                                       throws MBeanServerNotFoundException

  Attempt to find a locally running MBeanServer. Fails if no MBeanServer can be found. Logs a warning if more than one MBeanServer found, returning the first one from the list.

  参数:

  agentId - the agent identifier of the MBeanServer to retrieve. If this parameter is null, all registered MBeanServers are considered. If the empty String is given, the platform MBeanServer will be returned.

  返回:

  the MBeanServer if found

  抛出:

  MBeanServerNotFoundException - if no MBeanServer could be found

  public static Class<?>[] parameterInfoToTypes​(@Nullable
                                                MBeanParameterInfo[] paramInfo)
                                         throws ClassNotFoundException

  Convert an array of MBeanParameterInfo into an array of Class instances corresponding to the parameters.

  参数:

  paramInfo - the JMX parameter info

  返回:

  the parameter types as classes

  抛出:

  ClassNotFoundException - if a parameter type could not be resolved

• parameterInfoToTypes

  @Nullable
  public static Class<?>[] parameterInfoToTypes​(@Nullable
                                                MBeanParameterInfo[] paramInfo,
                                                @Nullable
                                                ClassLoader classLoader)
                                         throws ClassNotFoundException

  Convert an array of MBeanParameterInfo into an array of Class instances corresponding to the parameters.

  参数:

  paramInfo - the JMX parameter info

  classLoader - the ClassLoader to use for loading parameter types

  返回:

  the parameter types as classes

  抛出:

  ClassNotFoundException - if a parameter type could not be resolved

• getMethodSignature

  public static String[] getMethodSignature​(Method method)

  Create a String[] representing the argument signature of a method. Each element in the array is the fully qualified class name of the corresponding argument in the methods signature.

  参数:

  method - the method to build an argument signature for

  返回:

  the signature as array of argument types

• getAttributeName

  public static String getAttributeName​(PropertyDescriptor property,
                                        boolean useStrictCasing)

  Return the JMX attribute name to use for the given JavaBeans property.

  When using strict casing, a JavaBean property with a getter method such as getFoo() translates to an attribute called Foo. With strict casing disabled, getFoo() would translate to just foo.

  参数:

  property - the JavaBeans property descriptor

  useStrictCasing - whether to use strict casing

  返回:

  the JMX attribute name to use

• appendIdentityToObjectName

  public static ObjectName appendIdentityToObjectName​(ObjectName objectName,
                                                      Object managedResource)
                                               throws MalformedObjectNameException

  Append an additional key/value pair to an existing ObjectName with the key being the static value identity and the value being the identity hash code of the managed resource being exposed on the supplied ObjectName. This can be used to provide a unique ObjectName for each distinct instance of a particular bean or class. Useful when generating ObjectNames at runtime for a set of managed resources based on the template value supplied by a ObjectNamingStrategy.

  参数:

  objectName - the original JMX ObjectName

  managedResource - the MBean instance

  返回:

  an ObjectName with the MBean identity added

  抛出:

  MalformedObjectNameException - in case of an invalid object name specification

• getClassToExpose

  public static 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).

  This implementation returns the superclass for a CGLIB proxy and the class of the given bean else (for a JDK proxy or a plain bean class).

  参数:

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

  返回:

  the bean class to expose

• getClassToExpose

  public static Class<?> getClassToExpose​(Class<?> clazz)

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

  This implementation returns the superclass for a CGLIB proxy and the class of the given bean else (for a JDK proxy or a plain bean class).

  参数:

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

  返回:

  the bean class to expose

• isMBean

  public static boolean isMBean​(@Nullable
                                Class<?> clazz)

  Determine whether the given bean class qualifies as an MBean as-is.

  This implementation checks for DynamicMBean classes as well as classes with corresponding "*MBean" interface (Standard MBeans) or corresponding "*MXBean" interface (Java 6 MXBeans).

  参数:

  clazz - the bean class to analyze

  返回:

  whether the class qualifies as an MBean

  Return the Standard MBean interface for the given class, if any (that is, an interface whose name matches the class name of the given class but with suffix "MBean").

  参数:

  clazz - the class to check

  返回:

  the Standard MBean interface for the given class

• getMXBeanInterface

  @Nullable
  public static Class<?> getMXBeanInterface​(@Nullable
