从命令行重写YML配置文件的Spring Boot

Question

我不想使用命令行覆盖现有的YML文件配置文件，所以我这样做了。

null

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

@Configuration
@EnableAutoConfiguration
@ComponentScan
public class SuchApplication implements CommandLineRunner {

    @Autowired
    private DogeService dogeService;

    @Override
    public void run(String... args) {
        System.out.println("AutoConfiguration should have wired up our stuff");
        System.out.println("Let's see if we are doge-worthy...");
        if (dogeService.requiresDogeness()) {
            System.out.println(dogeService.leDoge());
        } else {
            System.out.println("No Doge for us :(");
        }
    }

    public static void main(String[] args) throws Exception {
        SpringApplication.run(SuchApplication.class, args);
    }
}

spring:
  profiles.active: default
---
spring:
  profiles: default

doge:
  wow: 10
  such: so
  very: true

---
spring:
   profiles: unit-test
doge:
  wow: 4
  such: so
  very: true

我在Spring Boot上也遇到了类似的问题，并在配置类中用这个注释解决了这个问题...

@PropertySource("classpath:application.yml")

但是从正式的Spring文档来看，这个注释看起来是不必要的，这就是为什么我没有在第一次尝试中添加。
