Listing 12-2. DocumentServiceFacade.java
package com.apress.isf.spring.service;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import com.apress.isf.java.model.Document;
import com.apress.isf.java.service.DocumentService;
import com.apress.isf.spring.data.DocumentDAO;
@Component("documentFacade")
public class DocumetServiceFacade implements DocumentService {
}
@Autowired
DocumentDAO documentDAO;
public List getAllDocuments(){
return documentDAO.getAll();
}
public Document saveDocument(String id, Document document) {
return documentDAO.save(id, document);
}
public Document removeDocumentById(String id) {
return documentDAO.removeById(id);
}
public Document findDocumentById(String id){
return documentDAO.findById(id);
}
public boolean updateLocationFromDocumentId(String documentId, String location) {
Document document = documentDAO.findById(documentId);
if(null == document)
return false;
document.setLocation(location);
saveDocument(documentId, document);
return true;
}
Listing 12-2 shows the DocumentServiceFacade class. This class is using the DocumentDAO implementation
that takes care of persistence because it has direct access to the database. Listing 12-3 shows the DocumentDAO
implementation class that needs to be modified as well.
