SpringBoot's custom configuration file

---

The configuration file of the SpringBoot project, by default, the file name is application, and the following three formats can be used as the configuration file of the SpringBoot project:

• application.properties

• application.yml

• application.yaml

• 

自定义配置文件：

In the SpringBoot project configuration column in the IDEA development environmentProgram arguments , specify the configuration file name by setting temporary properties, and identify the custom-named properties, yml, and yaml format files as SpringBoot configuration files:

--spring.config.name=MyApplication  #配置文件名

--spring.config.location=classpath:/Myapplication.yml #配置文件类路径、全路径

• ,If you want to configure multiple attributes in the above way, use separators between multiple attribute values .
• The name of the configuration file can be modified by setting the startup parameters
• The configuration file can modify the path by setting the startup parameters
• Configuration files in microservice development are dynamically configured through the configuration center (SpringCloud technology)

Custom configuration file:重要说明

---

• Single-server projects: The need to use custom configuration files is low.
• Multi-server projects: There is a high demand for custom configuration files, and all configurations are placed in one directory for unified management.
• Based on SpringCloud technology, all servers will no longer set configuration files, but set them through the configuration center and dynamically load configuration information.
