public class InvocableHandlerMethod
extends HandlerMethod
```
Provides a method for invoking the handler method for a given message after resolving its method argument values through registered HandlerMethodArgumentResolvers.
Use setMessageMethodArgumentResolvers(org.springframework.messaging.handler.invocation.HandlerMethodArgumentResolverComposite) to customize the list of argument resolvers.

```
public InvocableHandlerMethod(HandlerMethod handlerMethod)
```
    Create an instance from a HandlerMethod.
  - InvocableHandlerMethod
```
public InvocableHandlerMethod(Object bean,
                              Method method)
```
    Create an instance from a bean instance and a method.
  - InvocableHandlerMethod
```
public InvocableHandlerMethod(Object bean,
                              String methodName,
                              Class<?>... parameterTypes)
                       throws NoSuchMethodException
```
    Construct a new handler method with the given bean instance, method name and parameters.
    参数:
    bean - the object bean
    methodName - the method name
    parameterTypes - the method parameter types
    抛出:
    NoSuchMethodException - when the method cannot be found

  - setMessageMethodArgumentResolvers
```
public void setMessageMethodArgumentResolvers(HandlerMethodArgumentResolverComposite argumentResolvers)
```
    Set HandlerMethodArgumentResolvers to use to use for resolving method argument values.
  - setParameterNameDiscoverer
```
public void setParameterNameDiscoverer(ParameterNameDiscoverer parameterNameDiscoverer)
```
    Set the ParameterNameDiscoverer for resolving parameter names when needed (e.g. default request attribute name).
    Default is a DefaultParameterNameDiscoverer.
  - invoke
```
public Object invoke(Message<?> message,
                     Object... providedArgs)
              throws Exception
```
    Invoke the method after resolving its argument values in the context of the given message.
    Argument values are commonly resolved through HandlerMethodArgumentResolvers. The providedArgs parameter however may supply argument values to be used directly, i.e. without argument resolution.
    参数:
    message - the current message being processed
    providedArgs - "given" arguments matched by type, not resolved
    返回:
    the raw value returned by the invoked method
    抛出:
    Exception - raised if no suitable argument resolver can be found, or if the method raised an exception
  - doInvoke
```
protected Object doInvoke(Object... args)
                   throws Exception
```
    Invoke the handler method with the given argument values.
    抛出:
    Exception
  - getDetailedErrorMessage
```
protected String getDetailedErrorMessage(String text)
```
    Adds HandlerMethod details such as the bean type and method signature to the message.
    参数:
    text - error message to append the HandlerMethod details to
