Here is my last attempt but it is still giving me the error above:
config.yml:
-----------
logging:
level: INFO
loggers:
br.com.tecnopon.phoenix: DEBUG
server:
rootPath: /api/*
PhoenixApplication.java:
-----------
public class PhoenixApplication extends Application<PhoenixConfiguration> {
public static void main(final String[] args) throws Exception {
new PhoenixApplication().run(args);
}
@Override
public String getName() {
return "Phoenix";
}
@Override
public void initialize(final Bootstrap<PhoenixConfiguration> bootstrap)
{
bootstrap.addBundle(new AssetsBundle("/assets", "/", "index.htm",
"static"));
}
@Override
public void run(final PhoenixConfiguration configuration,
final Environment environment) {
final HelloWorldResource resource = new HelloWorldResource(
configuration.getTemplate(),
configuration.getDefaultName()
);
final TemplateHealthCheck healthCheck =
new TemplateHealthCheck(configuration.getTemplate());
environment.healthChecks().register("template", healthCheck);
environment.jersey().register(resource);
}
}
