Result Annotation

The `@Result` annotation allows the definition of `Action` results in the `Action` class rather than an XML file.

| The `@Result` annotation lives at the `Action` class level and not the method level. This matches what is found in an XML-based `Action` configuration. Do not be tempted to annotate your `Action`'s methods; it will not work.

In order for `@Result` and `@Results` annotations to be configured correctly you must set the `actionPackages` filter `init-param` to a comma-separated list of packages containing the annotated `Action` classes. See Zero Configuration for further information; there are `Action` class naming conventions if you don't implement the `Action` interface and other tidbits there.

## `@Result` Annotation Parameters

| See org.apache.struts2.config.Result annotation JavaDocs.

- name - Result name; default `Action.SUCCESS`
- value - Value of result (result destination)
- type - Type of result; default `NullResult`. For example:
  - `ServletRedirectResult`
  - `ServletActionRedirectResult` - Equivalent to `redirect-action` type in XML config.
  - `TilesResult`
- params

## `@Result` – Defining a Single Result

Map the "success" result (explicitly named) to a Tile definition named "/home.page".

Defining a Single Result

    @Result(name="success", value="/home.page", type=TilesResult.class)
    public class HomeAction extends ActionSupport {
        // ...
    }

## `@Results` – Defining Multiple Results

Defines a set of results for an `Action`.

Defining Multiple Results

    @Results({
        @Result(name="success", value="/home.page", type=TilesResult.class),
        @Result(name="homeError", value="/homeError.page", type=tilesResult.class)
    })
    public class HomeAction extends ActionSupport {
        // ....
    }
