Invalid parameters when springboot project starts

Today, I started an springboot project and found that all the parameters I entered when I started could not take effect, but the configuration of yaml file took effect. After checking for half a day, I finally found that there was a problem in the original startup class. The original code is as follows

public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class);
    }
}

Change the parameters of run method and add args parameters as follows

public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class,args);
    }
}

After startup, the specified parameters take effect.

springboot Project Startup Parameter Setting Problem

Several Commonly Used Startup Modes of Spring boot Project

Maven startup specifies that Profile passes through-P, such as mvn spring-boot: run-P test, but this is Profile of Maven.

If you want to specify spring. profiles. active for spring-boot, you must use mvn spring-boot: run-Drun. profiles=test If you run the jar file directly from the command line, use java-jar-Dspring. profiles. active = test demo-0. 0.1-SNAPSHOT. jar If you use the development tool and run the Application. java file to start, add the parameter spring. profiles. active=test

war package deployment mode

For war package deployment mode, you need to make the following configuration in the startup class

public class TestApplication extends SpringBootServletInitializer {
    public static void main(String[] args) {
        SpringApplication.run(TestApplication.class, args);
    }
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(TestApplication.class);
    }
}
