1. SpringBoot startup under idea: specify configuration file
2. The project has been packaged, run configuration
1). Use java -jar to start based on the configuration file under (1)
2) Specify other configuration files application-pro.yml in the project to start the project
3) Start the springboot project based on (3) on the Linux server
1. SpringBoot startup under idea: specify configuration file
The Springboot project has the following configuration files
The main configuration file application.yml,
Test environment: application-test.yml
Production environment: application-pro.yml
Development environment: application-dev.yml
During the development process, the actual configuration file used is usually specified in the main configuration file
spring:
profiles:
active: dev2. The project has been packaged, run configuration
You need to make sure that the project has been packaged as a jar package: springboot-demo.jar
1). Use java -jar to start based on the configuration file under (1)
java -jar springboot-demo.jar
2) Specify other configuration files application-pro.yml in the project to start the project
java -jar springboot-demo.jar --spring.profiles.active=test
Another startup command (when the previous startup command fails, use the following one, or just use this one)
java -jar -Dspring.profiles.active=test springboot-demo.jar
3) Start the springboot project based on (3) on the Linux server
How to run jar
java -jar xx.jar --spring.profiles.active=dev
example
java -jar -Dspring.profiles.active=test springboot-demo.jar
Startup that does not show log printing
nohup java -jar -Dspring.profiles.active=test springboot-demo.jar &
3. During the development process, idea specifies a configuration file in a certain environment to start the project
Method 1: multiple configuration files, when starting the project, you need to modify the configuration information in the upper right corner, as shown in the figure below
Select Configuration — "Environment —" Program arguments (the main method startup method: the priority is higher than the activation in the configuration file)
// 在IDE Arguments里面添加
--spring.profiles.active=dev
add configuration
Configure startup parameters
--spring.profiles.active=test
If you see the log shown in the figure below in the startup log, it means that the specified configuration file starts successfully.
Method 2: In addition to specifying the Profile in the configuration file and the command line, you can also specify it in the startup class, through the SpringApplication.setAdditionalProfiles method
public void setAdditionalProfiles(String... profiles) {
this.additionalProfiles = new LinkedHashSet<String>(Arrays.asList(profiles));
}Method 3: Select Configuration - "Environment -" VM options (JVM startup mode), and enter the following code:
-Dspring.profiles.active=dev
