我正在尝试将命令行args传递给在Docker容器中运行的Spring Boot应用程序的main方法。从命令行运行，我将执行以下操作：
$ mvn spring-boot:run -Dspring-boot.run.arguments=--greeting=Hello,--recipient=World
该应用程序需要提取这些arg并对其进行一些处理：
public static void main(String[] args) {
Options options = new Options();
Option greeting = new Option("-g", "greeting", true, "Greeting");
greeting.setRequired(true);
greeting.addOption(greeting);
Option recipient = new Option("-r", "recipient", true, "Recipient");
recipient.setRequired(true);
recipient.addOption(recipient);
try {
cmd = parser.parse(options, args);
} catch (ParseException e) {
System.out.println(e.getMessage());
formatter.printHelp("utility-name", options);
System.exit(1);
}
// Do some processing using these args ...
// Run the Spring Boot app
SpringApplication.run(SpringBootApp.class, args);
}
我试过简单地使用-e标志传递它们：
docker run …
