SpringBoot的多环境配置

There are 4 places to put configuration files in SpringBoot project;

1. file/application.yml
2. file/config/application.yml
3. classpath/application.yml
4. classpath/application.yml

different configuration files can coexist,but different configuration files have different priority from 1 to 4
for example:

1. file/application.yml config server.port: 8081
2. file/config/application.yml config server.port: 8082
3. classpath/application.yml config server.port: 8083
4. classpath/appliation.yml config server.port: 8084

if file/application.yml exist,this application will work in 8081 prot;if delete file/application.yml,this applcaition will work with 8082 port…etc
By default, configuration files is classpath/applicaiton.yml

properties配置文件实现多环境的配置/切换

now ,create multiple configuration files in resource path:

1. applicaton.propertiesconfig server.port=8080
2. application-test.properties config server.port=8081
3. application-dev.properties config server.port=8082

if run this application without any others conifguration file ,this application will run with 8080 port;
if you want make application-test.properties cover application.yml you can append a message in application.properties:
spring.profiles.active=test
In the same way, if you want to cover application.properties with application-dev.properties;you can append spring.profiles.active: dev to application.properties;

yml配置文件实现多环境的配置/切换

yml allow split A file to multiple areas with —- ;
for example:
application.yml:

server:
    port: 8080
---
server:
    port: 8081
spring:
    profiles: test
---
server:
    port: 8082
spring:
    profiles:dev

in this case,application will work with 8080;if you want to active test environment

server:
    port: 8080
spring:
    profiles:
      active: test
---
server:
    port: 8081
spring:
    profiles: test
---
server:
    port: 8082
spring:
    profiles:dev
