Introducing Spring Framework

Chapter 10
Showing Your Spring Application
on the Web
In this chapter, you are going to show your Spring application called My Documents on the Web. You are going to
use Spring annotations so the code is clean and easy to read. Also, you are going to continue to use the embedded
database and the RowMapper from Chapter 9 so you can see something real in action.
To put your Spring application on the Web, you need to know about the MVC design pattern. The MVC design
pattern is the most used pattern for web applications. Let’s start coding, and as we go along I will talk more about this
famous pattern.
Persistence Layer
First, let’s start with the Persistence layer. Listing 10-1 shows your modified DocumentDAO implementation (this class is
from Chapter 9).
Listing 10-1. DocumentRepository.java.
package com.apress.isf.spring.data;
import java.util.List;
import javax.sql.DataSource;
import org.springframework.beans.factory.annotation.Autowired;
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;
