Question

我有一个Spring Boot应用程序，我有application.yml作为属性。我在同一个文件中有多个配置文件，如下所示：

private static URL getVertexConfiguration() throws MalformedURLException {
    try {
        // Code omitted
    } catch ( Throwable th ) {
        th.printStackTrace();
        return null;
    }
}

所以我的问题是，当我仅使用spring: profiles: dev property: one: bla two: blabla --- spring: profiles: preProd, prod another-property: fist: bla secong: blabla --- spring: profiles: prod property: one: prod-bla two: prod-blabla个配置文件运行应用程序时，Spring会合并两个配置文件，并且我可以在应用程序中同时看到prod和property ？

合并效果很好！

给定：

@SpringBootApplication
public class SoYamlSpringProfileMergeApplication {

    private final Data data;

    public SoYamlSpringProfileMergeApplication(Data data) {
        this.data = data;
    }

    @EventListener(ApplicationReadyEvent.class)
    public void showData() {
      System.err.println(data.getOne());
      System.err.println(data.getTwo());
      System.err.println(data.getThree());
    }

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

}

@Component
@ConfigurationProperties(prefix = "data")
class Data {

    private String one = "one default";

    private String two = "two default";

    private String three = "three default";

    public String getOne() {
        return one;
    }

    public String getTwo() {
        return two;
    }

    public String getThree() {
        return three;
    }

    public void setOne(String one) {
        this.one = one;
    }

    public void setTwo(String two) {
        this.two = two;
    }

    public void setThree(String three) {
        this.three = three;
    }
}

和

spring:
  profiles:
    active: "other"

---

spring:
  profiles: dev

data:
  one: one dev
  two: two dev

---

spring:
  profiles: prod

data:
  one: one prod
  two: two prod

---

spring:
  profiles: other

data:
  three: three other

将打印：

one dev
two dev
three other

并带有：

spring:
  profiles:
    active: "other,prod"

one prod
two prod
three other

重要的有效顺序：“其他产品” 很重要！

使用

spring:
  profiles:
    active: "prod,other"

将输出

one dev
two dev
three other

从“产品”中加载道具
与道具“ other”合并合并dev-values

多个具有相同名称的Spring配置文件
