org.apache.struts2.convention.annotation.Action

This annotation can be used to control the URL that maps to a specific method in an Action class. By default, the method that is invoked is the execute method of the action and the URL is based on the package and class names. This annotation allows developers to change the URL or invoke a different method. This also allows developers to specify multiple URLs that will be handled by a single class or a single method.

This can also be used via the Actions annotation to associate multiple URLs with a single method.

Here's an example:

public class MyAction implements Action {
  {@code @Action("/foo/bar")}
  public String execute() {}
}

exceptionMappings, interceptorRefs, params, results, value

Method from org.apache.struts2.convention.annotation.Action Detail:
ExceptionMapping[] exceptionMappings() { }
InterceptorRef[] interceptorRefs() { } Allows action methods to specify what interceptors must be applied to it.
String[] params() { }
Result[] results() { } Allows action methods to specifically control the results for specific return values. These results are not used for other method/URL invocations on the action. These are only used for the URL that this action is associated with.
String value() { } Allows actions to specify different URLs rather than the default that is based on the package and action name. This also allows methods other than execute() to be invoked or multiple URLs to map to a single class or a single method to handle multiple URLs.
