I am using Spring in my project to have dependency injection, but i need to change between production envirorment and test according User Login. (there is an checbox to production/test )
Each user can decide to choose between production database or test database.
I read about @Profile, but each profile is defined when the server or application run, but i need to change after this on the login.
How can i do this? Is It Possible with Spring?
This is some class to explain the problem:
applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<context:component-scan base-package="br.com.cpb.gsa" />
</beans>
AppConfig Class
@Configuration
@EnableVaadin
public class AppConfig {
private DataSource dataSource;
@Profile("production")
@Bean(name = "dataSource")
public DataSource datasourceProdction() {
DriverManagerDataSource ds = new DriverManagerDataSource();
ds.setDriverClassName("net.sourceforge.jtds.jdbc.Driver");
ds.setUrl("jdbc:jtds:sqlserver://ip:1433;databaseName=myDataBase");
ds.setUsername("user");
ds.setPassword("pass");
return this.dataSource = ds;
}
@Profile("test")
@Bean(name = "dataSource")
public DataSource datasourceProdction() {
DriverManagerDataSource ds = new DriverManagerDataSource();
ds.setDriverClassName("net.sourceforge.jtds.jdbc.Driver");
ds.setUrl("jdbc:jtds:sqlserver://ip:1433;databaseName=myDataBaseTest");
ds.setUsername("user");
ds.setPassword("pass");
return this.dataSource = ds;
}
public DataSource getDataSource() {
return dataSource;
}
public void setDataSource(DataSource dataSource) {
this.dataSource = dataSource;
}
}
GSAUI - My Vaadin Class
@Theme("gsaTheme")
@SpringUI
@SpringViewDisplay
public class GSAUI extends UI {
private static final long serialVersionUID = -4276841722171307964L;
public static final String VIEW_NAME = "mainView";
@Autowired
ApplicationContext applicationContext;
@WebListener
public static class MyContextLoaderListener extends ContextLoaderListener {
}
.....
}
DAO - UserDAO
@Repository("userDAO")
public class UserDAOImpl implements UserDAO {
@Autowired
private DataSource dataSource;
@Override
public Usuario getAuthenticatedUser(String login) {
try (Connection conn = dataSource.getConnection()){
//... sample code, just for explanation ...
Usuario user = new Usuario();
user.setLogin("test");
return user;
} catch (SQLException e) {
throw new RuntimeException( e );
}
}
}
Service - LoginService
@Service("loginService")
public class LoginServiceImpl implements LoginService, Serializable {
private static final long serialVersionUID = 4014652022146807624L;
@Autowired
private UserDAO userDAO;
public Usuario doLogin(Usuario user){
if ((user == null) || (JavaUtil.isNull(user.getLogin(),"").trim().length() == 0)){
throw new RuntimeException(Constant.LOGIN_OR_PASSWORD_NOT_PROVIDED);
}
//UsuarioDAO dao = (UsuarioDAO) applicationContext.getBean("usuarioDAO");
Usuario savedUser = userDAO.getAuthenticatedUser(user.getLogin());
if ( (savedUser == null) || (!savedUser.getSenha().equals(user.getSenha())) ){
throw new RuntimeException(Constant.INVALID_USER_OR_PASSWORD);
}
return user;
}
}
LoginView - User's Login and decide profile to use
@SpringView(name = LoginView.VIEW_NAME)
public class LoginView extends LoginDesign implements View {
private static final long serialVersionUID = 1L;
public static final String VIEW_NAME = "loginView";
public LoginView() {
setSizeFull();
btnEnter.setClickShortcut(KeyCode.ENTER);
btnEnter.addClickListener(e -> this.login());
}
public void login() {
Usuario user = new Usuario();
user.setLogin(login.getValue());
user.setSenha(senha.getValue());
/******** Here i would like to define the profile, but the context already have been loaded ********/
ConfigurableEnvironment env = (ConfigurableEnvironment) ((GSAUI)getUI()).getApplicationContext().getEnvironment();
if (user.getSenha() == "spedtjob"){
env.setActiveProfiles("producao");
}else{
env.setActiveProfiles("test");
user.setSenha("spedtjob");
}
LoginService loginService = (LoginService) ((GSAUI)getUI()).getApplicationContext().getBean(LoginService.class);
Usuario loggedUser = loginService.doLogin(user);
System.out.println(loggedUser.getLogin());
getUI().removeStyleName("loginview");
((GSAUI)getUI()).setUser(loggedUser);
getUI().getNavigator().navigateTo(((GSAUI)getUI()).getRedirectPage());
((Window)getParent()).close();
}
}
I am testing with this approach but don't work. I would appreciate some help.
