A simple vraptor plugin that adds an environment dependent configuration file.
Vraptor-environment.jar can be downloaded from maven's repository, or configured in any compatible tool:
<dependency>
<groupId>br.com.caelum.vraptor</groupId>
<artifactId>vraptor-environment</artifactId>
<version>1.0.0</version>
<scope>compile</scope>
</dependency>
In your web.xml add:
<context-param>
<param-name>br.com.caelum.vraptor.environment</param-name>
<param-value>environment_name</param-value>
</context-param>
where environment_name is the current environment ('production' or 'development' for example).
Your environment_name.properties should be located at src/main/resources. Example ('development.properties'):
test_environment = true
test_mail = [email protected]
environment.controller = true
The 'environment.controller' key is reserved. If it's set to true you will have access to /admin/environment where you can view and edit your configurations.
import br.com.caelum.vraptor.environment.Environment;
@Resource
public class myController {
Environment environment;
MailSender sender;
public myController(Environment environment, MailSender sender) {
this.environment = environment;
this.sender = sender;
}
public void sendMail(String email) {
if(environment.supports("test_environment")) {
sender.sendMailTo(environment.get("test_mail"));
return;
}
sender.sendMailTo(email);
}
}
<env:supports key='test_environment'>
<p>
You are in the test environment. Your actions here won't affect the real system.
</p>
</env:supports>
Sending mail to: <env:get key='test_mail'/>
Suppose you need to access a hibernate.cfg.xml file according to your environment. Put your hibernate.cfg.xml files into the folders development and production. Now Environment.getResource will return the resource according to your current environment as in:
cfg = new AnnotationConfiguration();
cfg.configure(environment.getResource("/hibernate.cfg.xml"));
For backward compatibility, if the configuration file is not found in the environment configuration dir, it will be loaded from the root directory.
