I've got my application.properties file in /resources. I just want to change the name to <my-project-name>.properties. According to this reference, I should be able to change the name by specifying spring.config.name as an environment property:
java -jar myproject.jar --spring.config.name=myproject
But is there a way I can do this with an annotation or within my codebase somehow?
What I believe to be the most simple way to do this is to set a system property in the main method of your Spring Boot application entry point:
@SpringBootApplication
public class MyApplication {
public static void main(String[] args) {
// Tell Boot to look for my-project.properties instead of application.properties
System.setProperty("spring.config.name", "my-project");
SpringApplication.run(MyApplication.class, args);
}
}
System.setProperty("spring.config.location", "../config/");spring.config.location - classpath:{myproject}.properties
It's worked for me.
And make sure the same classpath is be placed in the value of PropertySource if it(@PropertySource) exits in whereever in the app.
.
├src
| └main
| └resources
| └myproject.properties
You can set inline properties using SpringApplicationBuilder:
SpringApplicationBuilder()
.properties("spring.config.name=myproject")
.sources(MyApplication.class)
.run(args);
new in new SpringApplicationBuilder()
@PropertySourceWell, I'm not sure if this is the best approach (if a Spring guru sees this, please let me know if it is :), but I did the following:
@PropertySource(value={"classpath:my-project.properties"}, ignoreResourceNotFound = true)
application.properties, it adds a new property source to the environment. You ask a misleading question, then post a different answer and accept it, it's like a monkey scratching its own back :)
spring.config.name didn't worked for me 😒😒You can also provide the following System properties (or environment variables) to change the behavior:
spring.config.name (SPRING_CONFIG_NAME): Defaults to an application as the root of the file name.spring.config.location (SPRING_CONFIG_LOCATION): The file to load (such as a classpath resource or a URL). A separate Environment property source is set up for this document and it can be overridden by system properties, environment variables, or the command line.$ java -jar myproject.jar --spring.config.location=classpath:/default.properties,classpath:/override.properties
