Hem Spring Boot 1.1.5 hem de 1.1.6'da bu sorunu yaşıyorum - Uygulamayı STS (3.6.0, Windows) içinden çalıştırdığımda gayet iyi çalışan bir @Value ek açıklamasını kullanarak bir sınıf yolu kaynağı yüklüyorum. Ancak, bir mvn paketi çalıştırıp daha sonra kavanozu çalıştırmayı denediğimde FileNotFound istisnaları alıyorum.
Kaynak, message.txt, src / main / kaynaklardadır. Jar'ı inceledim ve en üst düzeyde (application.properties ile aynı düzeyde) "message.txt" dosyasını içerdiğini doğruladım.
İşte uygulama:
@Configuration
@ComponentScan
@EnableAutoConfiguration
public class Application implements CommandLineRunner {
private static final Logger logger = Logger.getLogger(Application.class);
@Value("${message.file}")
private Resource messageResource;
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
@Override
public void run(String... arg0) throws Exception {
// both of these work when running as Spring boot app from STS, but
// fail after mvn package, and then running as java -jar
testResource(new ClassPathResource("message.txt"));
testResource(this.messageResource);
}
private void testResource(Resource resource) {
try {
resource.getFile();
logger.debug("Found the resource " + resource.getFilename());
} catch (IOException ex) {
logger.error(ex.toString());
}
}
}
İstisna:
