Spring Boot project shows the Login page

That is the default behavior. to change this, you have a few options:

You can remove the Spring Boot Security dependency:

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>

You can desable autoconfiguration. To do so; in your main class, to: @SpringBootApplication append: (exclude = { SecurityAutoConfiguration.class }) so that it looks like:

   @SpringBootApplication(exclude = { SecurityAutoConfiguration.class })
   public static void main(String[] args) {
            SpringApplication.run(SpringBootSecurityApplication.class, args);
        }
    }

you can also do this from the application.properties file

For more information on desableing Auto-Configuration and setting up your own. Reference: Spring Boot Security Auto-Configuration

If you don't want login page (from Spring-Security) remove the following dependency from your pom.xml and do maven update to refresh the dependencies on the class path.

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-security</artifactId>
</dependency>

Or if you want to use the Spring-Security then on console it will display the default password like below :
