What is username and password when starting Spring Boot with Tomcat?
<p>When I deploy my Spring application via Spring Boot and access <code>localhost:8080</code> I have to authenticate, but what is the username and password or how can I set it?  I tried to add this to my <code>tomcat-users</code> file but it didn't work: </p>

<pre><code>&lt;role rolename="manager-gui"/&gt;
    &lt;user username="admin" password="admin" roles="manager-gui"/&gt;
</code></pre>

<p>This is the starting point of the application:</p>

<pre><code>@SpringBootApplication
public class Application extends SpringBootServletInitializer {

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

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }
}
</code></pre>

<p>And this is the Tomcat dependency:</p>

<pre><code>&lt;dependency&gt;
    &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
    &lt;artifactId&gt;spring-boot-starter-tomcat&lt;/artifactId&gt;
    &lt;scope&gt;provided&lt;/scope&gt;
&lt;/dependency&gt;
</code></pre>

<p>How do I authenticate on <code>localhost:8080</code>?</p>
