Introducing Spring Framework

Chapter 8 ■ Give Advice to Your Spring Application
Let’s start modifying your code and getting rid of the logs from your classes. Remember that you need to take care
of the logging concern by separating it from the classes to avoid scattering and tangling. You are going to start with the
SearchEngine.java class, adding a new method just for testing one of your advice types (see Listing 8-2), then your
SearchEngineService.java class (see Listing 8-3).
Listing 8-2. SearchEngine.java
package com.apress.isf.java.service;
import java.util.List;
import com.apress.isf.java.model.Document;
import com.apress.isf.java.model.Type;
public interface SearchEngine {
public List findByType(Type documentType);
public List listAll();
}
public List findByLocation(String location);
Listing 8-3. SearchEngineService.java
package com.apress.isf.spring.service;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import com.apress.isf.java.model.Document;
import com.apress.isf.java.model.Type;
import com.apress.isf.java.service.SearchEngine;
import com.apress.isf.spring.data.DocumentDAO;
public class SearchEngineService implements SearchEngine {
private DocumentDAO documentDAO;
public SearchEngineService(){
}
public DocumentDAO getDocumentDAO() {
return documentDAO;
}
public void setDocumentDAO(DocumentDAO documentDAO) {
this.documentDAO = documentDAO;
}
