#1

Boa tarde,

preciso ler um arquivo properties que está na minha pasta /WEB-INF/empresas.properties

Tentei da seguinte forma:


@Resource
public class IndexController {

	private UsuarioLogado user;
	private final Result result;
	private List<String> lojas = new ArrayList<>();
	
	public IndexController(UsuarioLogado user, Result result) {

		this.user = user;
		this.result = result;
	
	}
	@Path("/index/index")
	public void index(){
	
		System.out.println("oi");
		try {
			Properties props = new Properties();
			FileInputStream inStream = new FileInputStream("/WEB-INF/empresas.properties");
			props.load(inStream);
			
                        System.out.println(props.getProperty("empresa"));
		
			
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
		
	}

}

porém não obitive sucesso a mensagem que apareceu no meu console foi:

java.io.FileNotFoundException: /WEB-INF/empresas.properties (No such file or directory)

Desde já agradeço a ajuda!!!

Faça assim:

[code]
@Component
@ApplicationScoped
public class ApplicationService {

private final Logger logger = LoggerFactory.getLogger(this.getClass());
private ServletContext context;

public ApplicationService(ServletContext context) {
	this.context = context;
}

public String getURI(String dir) {
	if (dir == null)
		dir = "";

	String uri = context.getInitParameter("vraptor.reports.path");
	return context.getRealPath(uri != null ? uri.trim() : "WEB-INF") + dir;
}

public Properties getProperties(String dir) {
	try {
		Properties prop = new Properties();
		InputStream in = new FileInputStream(getURI(dir));
		prop.load(in);
		in.close();

		return prop;
	} catch (Exception e) {
		logger.error("Unable to get properties file.", e);
		throw new RuntimeException(e);
	}
}[/code]

Daí basta você receber o ApplicationService no seu construtor e chamar o getProperties("/empresas.properties")…
O segredo está na ServletContext…
