Scenario: Adding handlers for operations around CRUD

Create a TextCreateHandler class implementing the ActionHandler interface in CorrespondenceManagementSolutionTemplate/Services project. This interface contains the preProcess() and postProcess() methods which are called before and after the create method respectively:

package com.adobe.icc; 
 
import java.util.Map; 
import com.adobe.icc.dbforms.obj.TextModule; 
import com.adobe.livecycle.content.repository.action.ActionHandler; 
import com.adobe.livecycle.content.repository.action.ActionType; 
 
/** 
 * TextCreateHandler is the handler associated with the Create operation of the Form. The preProcess() and postProcess() methods of 
 * this class are invoked just before and after the Create operation. 
 */ 
public class TextCreateHandler implements ActionHandler { 
 
        private static final String PREFIX = "PREFIX"; 
    /** 
     * This method is invoked just prior to the Create operation of TextModule. The first parameter of this API is the form object that 
     * is being Created. 
     */ 
    public void preProcess(String nodeType, ActionType actionType, Object obj, Map<String, Object> arg1) 
    { 
        TextModule text = (TextModule) obj; 
                text.setName(PREFIX + text.getName()); 
    } 
     
    /** 
     * This method is invoked just after to the Create operation of Text. The first parameter is the form object that has been 
     * Created. 
     */ 
    public void postProcess(String nodeType, ActionType actionType, Object arg0, Map<String, Object> arg1) { 
        // Do nothing 
    } 
}

Configuring the Handler by adding the following entry to the <bp:blueprint> section of CorrespondenceManagementSolutionTemplate\Services\resources\META-INF\spring\osgi-context.xml file:

<bp:reference interface="com.adobe.livecycle.content.repository.RepositoryService" />

Update the AssetDefinitionDeployer class to add a private variable repositoryService of class com.adobe.livecycle.content.repository.RepositoryService:

@Autowired 
private RepositoryService repositoryService;

and add the following code to the afterPropertiesSet() method:

List<ActionHandler> handlers = new ArrayList<ActionHandler>(); 
handlers = new ArrayList<ActionHandler>(); 
handlers.add(new TextCreateHandler()); 
repositoryService.addActionHandlers(ActionHandlerService.APP_ROOT_GLOBAL, TextModule.class.getName(), ActionType.CREATE, handlers);
