设置多个配置文件的弹簧配置

Question

I have more than one profile in my application configuration file, application.yml , like the following example:

spring:
  application:
    name: my-super-app
database:
  secret: "default secret"
this:
  that: "default value..."

---

spring:
  profiles: staging


---

spring:
  profiles: qa
database:
  secret: "foo bar"

---

spring:
  profiles: playground
database:
  secret: "foo bar"

---

spring:
  profiles: production
database:
  secret: "foo bar"

As it is obvious, I redundantly set the database.secret configuration for qa , playground and production profiles, except staging . Is there a way to set it once for these three profiles, something grouping the profiles or inheriting from a base profile?

Answer 1

You can combine the profiles in a comma separated list ( qa,playground,production ), like this:

spring:
  application:
    name: my-super-app
common-secret: "foo bar"
database:
  secret: "default secret"
this:
  that: "default value..."

---

spring:
  profiles: staging


---

spring:
  profiles: qa

---

spring:
  profiles: playground

---

spring:
  profiles: production

---

spring:
  profiles: qa,playground,production
database:
    secret: "foo bar"

Alternately you can set a "shared variable", something like this:

spring:
  application:
    name: my-super-app
common-secret: "foo bar"
database:
  secret: "default secret"
this:
  that: "default value..."

---

spring:
  profiles: staging


---

spring:
  profiles: qa
database:
  secret: ${common-secret}

---

spring:
  profiles: playground
database:
  secret: ${common-secret}

---

spring:
  profiles: production
database:
    secret: ${common-secret}
