How to override default Spring Boot Login page? - spring-boot

Question

I'm totally new with Spring Boot 2 and I have this simple application that I'm trying to run. Unfortunately, each time I run my service, I end up with this login form from Spring Boot. Is there any way I can override this?
I've already tried the solution from this question but it didn't work for me:

public static void main(String[] args){
SpringApplication.run(Application.class, args);
}
#RequestMapping(value="/greeting", method=RequestMethod.GET)
public String sayHello () {
return "Hello from Spring Boot!";
}
}

I tried the solution of excluding the SecurityAutoConfiguration.class but I somehow got this error message when I tried to access my endpoint:

Answer 1

I'm assuming you're using Spring Boot 2, as you did not mention which version of Spring you are using. In spring boot 2, you cannot disable the default login via properties files as you could in spring boot 1. There's a few ways of doing this depending on what you're trying to achieve.
Permit All Access, Secure Endpoints Later
Add a class titled SecurityConfig that looks like this:
#Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests().antMatchers("/**").permitAll();
}
}
This removes authentication on all endpoints in your service. Later on, you can configure security further via this class.
Remove Security Auto Configuration
When Spring Security is found on the classpath, Spring Boot automatically configures security. You can remove it all together if you don't want it auto configured by changing your #SpringBootApplication annotation.
#SpringBootApplication(exclude = {SecurityAutoConfiguration.class})
