springboot notes 05 - profile multi-environment configuration switch

Foreword

An application from development to on-line, often need to go through several stages, such as development, testing, on-line. The configuration used in each stage of the environment may have been different, Springboot applications can be easily configured to switch each environment. So, today introduces Springboot profiles multi-environment configuration switches.

Four ways to switch profiles multi-environment configuration

1. Profiles of more than
2. yml Multiple Document block the way
3. Setup parameters
4. Set up a virtual machine parameters

1, multiple configuration files

1.1, modify application.properties

server.port=8080

1.2, the master boot operation class

1.3, create application-dev.properties and application-prod.properties

application-dev.properties

server.port=8090

application-prod.properties

server.port=9090

1.4, the activation profiles in application.properties

server.port=8080
spring.profiles.active=prod

1.5, the master boot operation class

PS: If you activate dev, will use port 8090.

2, yml block mode multi-document

2.1, create application.yml

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

PS: yml to "---" to separate documents block

2.2, run the main startup class

3, program arguments

3.1, setup parameters

--spring-profiles.active=prod

PS:这条指令也可以用于程序被打包成jar包后，在命令行指定激活环境。并且优先级比配置文件中高。

3.2, run the main startup class

4, set the virtual machine parameters

4.1, set the virtual machine parameters

-Dspring-profiles.active=dev

4.2, run the main startup class

to sum up

By this in several ways, Springboot program can be in different environments using different configurations of.
