Introducing Spring Framework

Chapter 6 ■ Using Resource Files
You are going to add a new interface, a Login class that can help you to authenticate a user providing an
e-mail and password and based on the environment you are working on. Let’s start by reviewing Listing 6-9 and
Listing 6-10. First, you will create your properties files and see how you can use them. Listing 6-9 shows some
Development environment values.
Listing 6-9. env_dev.properties
user.email=test@mydocuments.com
user.password=test123
Listing 6-10 shows some QA environment values.
Listing 6-10. env_qa.properties
user.email=qa@mydocuments.com
user.password=3$aqw1
Let’s continue creating your login interface and its implementation. See Listings 6-11 and 6-12. Listing 6-11
shows a simple interface with only one method that accepts an e-mail and a password. The idea is to authorize a user
if these values are correct.
Listing 6-11. Login.java
package com.apress.isf.java.service;
public interface Login {
public boolean isAuthorized(String email, String pass);
}
Listing 6-12. LoginService.java
package com.apress.isf.spring.service;
import com.apress.isf.java.service.Login;
public class LoginService implements Login {
private String username;
private String password;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
