특별히 문제가 없어보이는데 아래의 로그와 같이 Exception 이 발생한 경우가 있었다.

응답이 늦어 JAVA default Timeout 시간을 초과했나보다.

아래와 같이 SpringBoot 기동 시 JAVA로 시간을 셋팅해 줬더니 이후 문제가 발생하지 않았다.
@SpringBootApplication @EnableScheduling @EnableAsync public class MainApplication extends SpringBootServletInitializer implements CommandLineRunner { @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) { System.setProperty("sun.net.client.defaultConnectTimeout", "10000"); System.setProperty("sun.net.client.defaultReadTimeout", "10000"); return builder.sources(MainApplication.class); } ... }
java, jackson, timeout,
