[SPRING] 스프링 부트와 함께 실행 가능한 jar 명령을 사용할 때 Resource FileNotFoundException

스프링 부트와 함께 실행 가능한 jar 명령을 사용할 때 Resource FileNotFoundException

내 스프링 부팅 응용 프로그램에서 https를 사용하려면 다음을 수행했습니다.

@Bean
@Inject
public EmbeddedServletContainerCustomizer containerCustomizer() throws FileNotFoundException
{
    final String absoluteKeystoreFile = ZenoTuringServiceApp.class.getClassLoader().getResource("test.jks").getFile();

    return (ConfigurableEmbeddedServletContainer factory) -> {
        TomcatEmbeddedServletContainerFactory containerFactory = (TomcatEmbeddedServletContainerFactory) factory;
        containerFactory.addConnectorCustomizers((TomcatConnectorCustomizer) (Connector connector) -> {
            connector.setSecure(true);
            connector.setScheme("https");
            connector.setAttribute("keystoreFile", absoluteKeystoreFile);
            connector.setAttribute("keystorePass", "test");
            connector.setAttribute("keystoreType", "JKS");
            connector.setAttribute("clientAuth", "false");
            connector.setAttribute("sslProtocol", "TLS");
            connector.setAttribute("SSLEnabled", true);
        });
    };
}

mvn spring-boot를 사용하여 실행할 경우 : 예상대로 작동합니다.

하지만 java -jar target / xxx-xxx-service-0.1.17-SNAPSHOT.jar을 사용하여 실행 가능한 jar 파일을 실행하면 FileNotFoundException이 발생합니다.

해결법

1. ==============================

   1.위의 주석과이 코드는 나를 도왔습니다 ..

   위의 주석과이 코드는 나를 도왔습니다 ..

   // support loading the JKS from the classpath (to get around Tomcat limitation)
   private static File getTuringKeyStoreFile() throws IOException {
       ClassPathResource resource = new ClassPathResource("test.jks");
   
       // Tomcat won't allow reading File from classpath so read as InputStream into temp File
       File jks = File.createTempFile("ssl_keystore", ".jks");
       InputStream inputStream = resource.getInputStream();
       try {
           FileUtils.copyInputStreamToFile(inputStream, jks);
       } finally {
           IOUtils.closeQuietly(inputStream);
       }
   
       return jks;
   }
