In many places, applications can use use Java 5 annotations as an alternative to XML and Java properties configuration. This page serves as a reference for all annotations across the framework.
Since 2.1, these annotations are provided by the Convention Plugin. Codebehind and Zero Config plugins are deprecated from 2.1 on.
Action annotations are available when the framework scans the classpath for Action classes, rather than specifying individual mappings through XML configuration. See the Zero Configuration Convention Plugin page for information on how to set up classpath scanning to allow the use of Action annotations.
Namespace Actions Annotation
Overrides the namespace Group of @Action annotations, maps multiple URLs to the same action
Defines the URL of an action
Defines an existing configuration package for the action's package to extend
Defines an action Result
Defines multiple Results InterceptorRefs Annotation
Gropup of @InterceptorRef annotations
Interceptor, or interceptor stack to be applied to at action
Group of @Result annotations
Defines a result for an action
Set the path of the action URL (used to overwrite the default)
Set where the results are located (used to overwrite the default)
Set the parent package of the actions (used to overwrite the default)
Group of @ExceptionMapping annotations
Defines an exception mapping
Defines what method to execute, or result to be returned if there are validation errors
To use these annotations, you have to specify the AnnotationWorkflowInterceptor to your interceptor stack.
Checks if there are any conversion errors for a field.
Checks that a date field has a value within a specified range.
Checks that a double field has a value within a specified range.
Checks that a field is a valid e-mail address.
Validates an expression.
Uses an OGNL expression to perform its validator.
Checks that a numeric field has a value within a specified range.
Validates a regular expression for a field.
Checks that a field is non-null.
Checks that a String field is not empty.
Checks that a String field is of the right length.
Invokes a regular expression to validate a String field.
Checks that a field is a valid URL.
Marker annotation for validation at Type level.
Used to group validation annotations.
Invokes the validation for a property's object type.
Use this annotation for your custom validator types.
In short, instead of specifying the types found in collections and maps as documented in Type Conversion, the collection's generic type is used. By using annotations, an application should be able to avoid using any
