Unable to set up basic authentication with Spring Boot REST API - spring

Question

I'm trying to set up a RESTful API with Spring Boot and I'm trying to enable basic authentication. How come I keep hitting a 403 Access Denied error? I'm sending my credentials as a header in Postman (see image attached). If I remove .anyRequest.authenticated(), it works fine. I don't want to remove that though because I would like basic authentication for every endpoint. What am I doing wrong?
Application.java
#SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
SecurityConfiguration.java
#Configuration
#EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/h2-console/*").permitAll()
.anyRequest().authenticated();
http.csrf().disable();
http.headers().frameOptions().disable();
}
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth
.inMemoryAuthentication()
.withUser("user").password("password").roles("USER");
}
}
Controller.java
#RestController
public class Controller {
#RequestMapping("/test")
public String index() {
return "Greetings from Spring Boot!";
}
}

Answer 1

After digging around in the Spring docs, it seems I understand what each of the chained method calls are for.
Anyway, the simple answer is that I needed .and().httpBasic() to enable Basic HTTP Authentication over my REST API.
.anyRequest().authenticated() simply mandates that every request is authenticated, but did not specify what method. Adding basic authentication means we can use basic auth to authenticate a user.
