Class ValidatorExtensionPostProcessor

java.lang.Object

org.appfuse.webapp.spring.ValidatorExtensionPostProcessor

All Implemented Interfaces:

org.springframework.beans.factory.config.BeanFactoryPostProcessor

public class ValidatorExtensionPostProcessor
extends Object
implements org.springframework.beans.factory.config.BeanFactoryPostProcessor

Adds commons validator configuration files to an existing Spring commons Validator Factory bean, possibly defined within a seperate Spring configuration file in a seperate jar file. By using this extension factory developers can add validation configuration for their own persistent classes to an AppFuse application without modifying any of the existing AppFuse Spring configuration or jar distribution files.

As an example consider the following Spring bean configuration:

 <bean class="org.appfuse.webapp.spring.ValidatorExtensionPostProcessor">
   <property name="validationConfigLocations">
     <list>
       <value>/WEB-INF/foo-validation.xml</value>
     </list>
   </property>
 </bean>
 

The sample adds a single validation configuration file (foo-validation.xml) to an existing Spring commons Validator Factory bean (a bean of class org.springmodules.validation.commons.DefaultValidatorFactory). Assuming the validator extension is included in a Spring configuration file called applicationContext-foo-validation.xml, and that this configuration file is added directly below WEB-INF in the Foo web project, then the normal war overlay process coupled with AppFuse's configuration file auto detection will ensure that the validation extension is automatically included into the application without requiring any modification of AppFuse's existing config files.
