如何设置 Spring Boot shell 的默认命令？

Question

如何为 Spring Boot Shell 应用程序定义默认命令？

现在我必须进入

java -jar app.jar calculate-cognitive-metrics ".\\src\\main\\java\\"

我想将其更改为

java -jar app.jar ".\\src\\main\\java\\"

，以便它默认执行此命令。

另外，当我尝试运行

java -jar app.jar --help

时，我得到这个

org.springframework.shell.CommandNotFound: No command found for '--help'

而不是帮助输出。我是 Java 和 Spring Shell 的新手，我已经检查过文档，但我真的不知道如何正确配置它来执行我想要的操作。

认知分析应用程序.java

@SpringBootApplication
public class CognitiveAnalysisApplication implements ApplicationRunner {

  public static void main(final String[] args) {
    SpringApplication.run(CognitiveAnalysisApplication.class, args);
  }

  @Override
  public void run(final ApplicationArguments args) throws Exception {
  }
}

ShellCommands.java（摘录）

  @ShellMethod(key = "calculate-cognitive-metrics")
  public void calculateCognitiveMetrics(
      final @ShellOption(defaultValue = "src/main/java") String directoryPath,
      final @ShellOption(defaultValue = "", value = "--html-report") String htmlReport,
      final @ShellOption(defaultValue = "", value = "--csv-report") String csvReport,
      final @ShellOption(defaultValue = "", value = "--json-report") String jsonReport
  ) throws IOException {

在终端中使用此命令：

java -jar app.jar calculate-cognitive-metrics --help

我本地的输出：
