Springboot (3): Configuration file-Multi-environment configuration

Source: Internet
Author: User

I. Benefits of multi-environment configuration

1. Different environment configuration can be configured with different parameters

2. Easy to deploy, improve efficiency, reduce errors

Second, the properties of multi-environment configuration

1. Configure activation options


Description: The development environment is activated here.

2. Add additional Profiles

Such as:

Development environment: Application-dev.properties

Test environment: Application-test.properties

Production environment: Application-prod.properties

Public Environment: Application.properties

Warm tips:

1, generally we put the public configuration in the public environment, each environment is unique in the corresponding environment, configuration activation options are generally configured in the public environment.

2. If the configuration of the public environment is in conflict with the configuration of the activation options environment, the other environment will overwrite the public environment configuration.

Three, YAML Multi-environment configuration

1. Configure activation options


2. In the configuration file add three in the English state of the dash to distinguish between different configuration environment





Server:  port: 80  tomcat:    uri-enconding: utf-8spring:   profiles:    active: dev  jackson:     date-format: yyyy-mm-dd hh:mm:ss    time-zone: asia/chongqingroncoo:   secret: ${random.value}  number: ${random.int}  number2:     less:      than:        ten:  ${random.int (}  number3:    in:      range):  ${random.int[1024,65536]}  name: zhangsan  desc: ${roncoo.name} is  a domain name---spring:  profiles:    active: testserver:   port: 9090---spring:  profiles:    active: devserver:   port: 8989

Comparison of two configuration modes

1, the Properties configuration multi-environment, need to add multiple configuration files, Yaml only need one accessory file

2, the difference in writing format, Yaml relatively concise, elegant

3, the disadvantage of Yaml: Can not be loaded by @propertysource annotations. If you need to load values using @propertysource annotations, use the properties file.

Five, after packaging, run

Such as:

Application-dev.properties Port: 8080

Application-test.properties Port: 9090

Application.properties Port: 80

Java-jar running the jar--spring.profiles.active=dev

Such as:

Java-jar Spring-boot-demo-2-1-0.0.1-snapshot.jar--spring.profiles.active=dev

Note: If the jar is run directly "Java-jar", then the configuration inside the application.properties is used, if the configuration inside the application.properties has a specified environment, then the specified environment is run.
