【问题描述】：
我使用的是 Spring Boot 应用程序，可交付成果是一个 JAR 文件。该文件需要使用命令java -cp "parser.jar" com.ef.Parser 运行并执行一些超出本问题范围的操作。在这种情况下，我有 2 个问题。
当我输入命令时
java -jar target/parser-1.5.7.RELEASE.jar com.ef.Parser，我可以运行该应用程序。但是，当我输入命令java -cp target/parser-1.5.7.RELEASE.jar com.ef.Parser 时，出现错误
Error: Could not find or load main class com.ef.Parser
这里有什么问题？
我有 Parser.java 包名称为 com.ef
代码如下，
@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);
}
}

第二个问题是当我运行命令mvn clean package 时，我在target 文件夹中得到parser-1.5.7.RELEASE.jar。如何使用pom.xml 配置将JAR 文件重命名为parser.jar？
我曾尝试手动重命名它，但是，这不起作用。
【问题讨论】：
-
Parser.java的包名是什么？你能发布完全相同的代码吗？
