14th Chapter Springboot + profile (different environments read different configurations)

Specific practices:

• Configurations for different environments set a profile, for example: The configuration configuration in the dev environment is in application-dev.properties, and the configuration in the PROD environment is configured in Application-prod.properties.
• Specify which file to use in Application.properties

1. Application-dev.properties(configuration under dev environment)

Profile = Dev_envrimont

2, Application-prod.properties(configuration under the PROD environment)

Profile = Prod_envrimont

3, Application.properties

1 Spring.data.mongodb.uri=mongodb://192.168.22.110:27017/myfirstmongodb2 3 # Spring.profiles.active4 Spring.profiles.active=dev

Description: The above configuration indicates the use of the configuration under the dev environment.

Note:spring.data.mongodb.uri=mongodb://192.168.22.110:27017/ Myfirstmongodb the configuration is application-dev.properties not configured

4. Controller

@Autowired     Private Environment env;            @RequestMapping ("/testprofile")    public  String testprofile () {         return env.getproperty ("Profile");    }

Test :

• The result of the above code execution is: Dev_envrimont and Mongodb://192.168.22.110:27017/myfirstmongodb
• If the application.properties configuration changes to: Spring.profiles.active=prod, the result is: Prod_envrimont
• If the configuration of application.properties is changed to: Spring.profiles.active=prod, profile= is also configured in Application.properties XXX (regardless of whether the configuration is above or below the Spring.profiles.active=prod), this time the result is: Prod_envrimont
• If the configuration of application.properties is changed to: Spring.profiles.active=prod, profile= is also configured in Application.properties XXX (regardless of whether the configuration is above or below Spring.profiles.active=prod), but application-prod.properties deleted the profile = Prod_envrimont, this time the result is: XXX

Conclusion:

• The public configuration of each environment is written in application.properties
• Each module's unique configuration is configured in its own application-{xxx}.properties file
• When the program reads, first read the configuration of the selected profile in Application.properties, if not read, it will be read from Application.properties.
