Examples of ValidationInterceptor

com.opensymphony.xwork2.validator.ValidationInterceptor
This interceptor runs the action through the standard validation framework, which in turn checks the action against any validation rules (found in files such as ActionClass-validation.xml) and adds field-level and action-level error messages (provided that the action implements {@link com.opensymphony.xwork2.ValidationAware}). This interceptor is often one of the last (or second to last) interceptors applied in a stack, as it assumes that all values have already been set on the action.
This interceptor does nothing if the name of the method being invoked is specified in the excludeMethods parameter. excludeMethods accepts a comma-delimited list of method names. For example, requests to foo!input.action and foo!back.action will be skipped by this interceptor if you set the excludeMethods parameter to "input, back".
The workflow of the action request does not change due to this interceptor. Rather, this interceptor is often used in conjuction with the workflow interceptor.
NOTE: As this method extends off MethodFilterInterceptor, it is capable of deciding if it is applicable only to selective methods in the action class. See MethodFilterInterceptor for more info.
Interceptor parameters:
- alwaysInvokeValidate - Defaults to true. If true validate() method will always be invoked, otherwise it will not.
- programmatic - Defaults to true. If true and the action is Validateable call validate(), and any method that starts with "validate".
- declarative - Defaults to true. Perform validation based on xml or annotations.
Extending the interceptor:
There are no known extension points for this interceptor.
Example code:
```
  <action name="someAction" class="com.examples.SomeAction"> <interceptor-ref name="params"/> <interceptor-ref name="validation"/> <interceptor-ref name="workflow"/> <result name="success">good_result.ftl</result> </action> <-- in the following case myMethod of the action class will not get validated --> <action name="someAction" class="com.examples.SomeAction"> <interceptor-ref name="params"/> <interceptor-ref name="validation"> <param name="excludeMethods">myMethod</param> </interceptor-ref> <interceptor-ref name="workflow"/> <result name="success">good_result.ftl</result> </action> <-- in the following case only annotated methods of the action class will be validated --> <action name="someAction" class="com.examples.SomeAction"> <interceptor-ref name="params"/> <interceptor-ref name="validation"> <param name="validateAnnotatedMethodOnly">true</param> </interceptor-ref> <interceptor-ref name="workflow"/> <result name="success">good_result.ftl</result> </action>

Validate the method receiver using Hibernate validator before invoking the method. If a validation failure occurs, put information about the failure in the request context and return a different outcome, without invoking the method. @deprecated @author Gavin King
