spring-boot run with environment

環境指定のspring-boot run

mvn spring-boot:run -Drun.jvmArguments="-Dspring.profiles.active=production"

環境を指定する

なんかまあこんな感じ。

src/main/java/Example.java

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.*;
import org.springframework.boot.autoconfigure.*;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.core.env.Environment;
import org.springframework.web.bind.annotation.*;

@RestController
@EnableAutoConfiguration
@Configuration
@PropertySource("classpath:/config/application.yml")
public class Example {

    @Autowired
    private Environment env;

    @RequestMapping("/")
    String home() {
        return env.getProperty("foo.bar");
    }

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

}

src/main/resources/config/application.yml

foo:
    bar: "hello, development!"
