public interface MethodBeforeAdvice extends BeforeAdvice {
Callback before a given method is invoked.
Params:
  • method – method being invoked
  • args – arguments to the method
  • target – target of the method invocation. May be null.
Throws:
  • Throwable – if this object wishes to abort the call. Any exception thrown will be returned to the caller if it's allowed by the method signature. Otherwise the exception will be wrapped as a runtime exception.
