23.6 Accessing Application Arguments（访问应用程序参数）

If you need to access the application arguments that were passed to SpringApplication.run(… ), you can inject a org.springframework.boot.ApplicationArguments bean. The ApplicationArguments interface provides access to both the raw String[] arguments as well as parsed option and non-option arguments,     
as shown in the following example:

您可以通过注入一个org.springframework.boot.ApplicationArguments bean去获取访问通过SpringApplication.run(… )传递的参数。ApplicationArguments参数接口即提供了访问原生String[]参数的方式，也提供了访问解析option（可选）和non-option（非可选）参数。举个例子：

import org.springframework.boot.*;
import org.springframework.beans.factory.annotation.*;
import org.springframework.stereotype.*;

@Component
public class MyBean {

	@Autowired
	public MyBean(ApplicationArguments args) {
		boolean debug = args.containsOption("debug");
		List<String> files = args.getNonOptionArgs();
		// if run with "--debug logfile.txt" debug=true, files=["logfile.txt"]
	}

}

Spring Boot also registers a CommandLinePropertySource with the    
 Spring Environment. This lets you also inject single application     
 arguments by using the @Value annotation.

Spring Boot还向Spring环境注册了一个CommandLinePropertySource。这使您同样能够通过使用注解@Value注入单应用参数。
