Here you can just use MethodUtil.getMethodName(method) to get its method representation, which will cache the method name for better performance.

Suggested change
buf.append(method.getDeclaringClass().getName())
return MethodUtil.getMethodName(method);

.append(":")
.append(method.getName())
.append("(");
boolean isFirst = true;
for (Class<?> clazz : method.getParameterTypes()) {
if (!isFirst) {
buf.append(",");
}
buf.append(clazz.getName());
isFirst = false;
}
buf.append(")");
return buf.toString();
}
