Introducing Spring Framework

Chapter 11 ■ Integrating Your Spring Application with External Systems
Listing 11-3 uses XStream, a library that serializes/deserializes objects into an XML String back and forth.
Because you need to save an actual document object, it is necessary to add this helper to the application. Note
in Listing 11-2 that there is a documentDAO.save(document)call. This is a new method that you will add to the
DocumentDAO implementation that will save a Document object. See Listing 11-4, the DocumentRepository class.
Listing 11-4. DocumentRepository.java
package com.apress.isf.spring.data;
import java.util.Date;
import java.util.List;
import javax.sql.DataSource;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.dao.EmptyResultDataAccessException;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Repository;
import com.apress.isf.java.model.Document;
@Repository("documentDAO")
public class DocumentRepository implements DocumentDAO {
@Autowired
private DataSource dataSource;
@Autowired
private String query;
@Autowired
private String insert;
@Autowired
private String find;
@Autowired
private String update;
public List getAll() {
return new JdbcTemplate(dataSource).query(query,
new DocumentRowMapper());
}
public Document findById(String id) {
Document updateDocument = null;
JdbcTemplate template = new JdbcTemplate(dataSource);
}
try {
updateDocument = template.queryForObject(find,
new Object[] { id },
new DocumentRowMapper());
} catch (EmptyResultDataAccessException ex) {}
return updateDocument;
