Eight, profile multi-environment configuration

Usually our program has multiple environments:

1. Development environment;

2. Production environment.

Wait

The configuration of the environment is different, we hope to switch the environment through a simple configuration, and springboot easily achieves this function:

1. Multiple environments require multiple configuration files

Generally, we have: application.properties configuration file by default , now we add two environment files , the file name format is: application-{profile}.properties :

1) application-dev.properties; // for development environment

2) application-prod.properties. // for production

The following configuration data source is an example:

The contents of application-dev.properties are as follows:

# development environment
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://本地IP:3306/test
spring.datasource.username=root
spring.datasource.password =Password

The contents of application-prod.properties are as follows:

# Production Environment
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://服务器IP:3306/test
spring.datasource.username=root
spring.datasource.password =Password

 

After configuring the file, we need to activate one of the configuration files and add the following configuration in application.properties:

# Environment configuration
spring.profiles.active=prod

As above, we activated the configuration file of the prod production environment, then when the program starts, it will naturally load the content of the application-prod.properties file
