나는 스프링 부트 앱으로 작업하며 결과물은 JAR 파일이다. 이 파일은 java -cp "parser.jar" com.ef.Parser 명령으로 실행하고이 질문의 범위를 벗어나는 일부 작업을 실행해야합니다. 이 시나리오에서는 두 가지 질문이 있습니다.java -cp와 java -jar의 차이점
java -jar target/parser-1.5.7.RELEASE.jar com.ef.Parser과 같은 명령을 입력하면 앱을 실행할 수 있습니다. 그러나, 명령어 java -cp target/parser-1.5.7.RELEASE.jar com.ef.Parser을 입력하면 오류가 발생합니다. Error: Could not find or load main class com.ef.Parser
무엇이 문제입니까?
나는pom.xml 파일이 제공
@EnableJpaRepositories("com.ef.repository")
@SpringBootApplication(scanBasePackages = {"com.ef"}, exclude = JpaRepositoriesAutoConfiguration.class)
public class Parser implements CommandLineRunner {
@Autowired
private IpAddressService ipAddressService;
public Parser() {
}
public static void main(String[] args) throws Exception {
SpringApplication application = new SpringApplication(Parser.class);
application.run(args);
}
@Override
public void run(String... args) throws Exception {
System.out.println("\nHello, Spring Boot!");
exit(0);
}
}
코드는 아래에 나와 있습니다 com.ef

두 번째 질문은이 mvn clean package 명령을 입력하면 target 폴더에 parser-1.5.7.RELEASE.jar이 표시됩니다. pom.xml 구성을 사용하여 JAR 파일의 이름을 parser.jar으로 바꾸는 방법은 무엇입니까?
수동으로 이름을 바꾸려고했으나 제대로 작동하지 않습니다.
'Parser.java'의 패키지 이름은 무엇인가? 똑같은 코드를 게시 할 수 있습니까? – Ravi
