Answer 1

The fallback method should have the same parameters as the original method, or one more parameter of type Throwable. Example, if your original method is:

@Retry(name = "getUserFindById", fallbackMethod = "getDefaultUser")
public User getUserFindById(String id) {
    // some logic
}

Your fallback method should like this:

public User getDefaultUser(String id, Throwable ex) {
    // some logic
}

Notice that the fallback method should also return the same type as the original method. Otherwise FallbackExecutor won't be able to find a matching fallback method and throw a NoSuchMethodException.
