title: Don't spring-boot-starter-web and spring-boot-starter-webflux work together?
body: <p>When I start to learn the <code>spring-webflux</code>, I have the question about this component.</p>
  <p>I built a simple project, using maven to manage it. I addded the dependencies related to <code>spring-boot-starter-web</code> and <code>spring-boot-starter-webflux</code>, like :</p>
  <pre><code>    &lt;dependency&gt;
          &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
          &lt;artifactId&gt;spring-boot-starter-webflux&lt;/artifactId&gt;
      &lt;/dependency&gt;
  
      &lt;dependency&gt;
          &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
          &lt;artifactId&gt;spring-boot-starter-web&lt;/artifactId&gt;
      &lt;/dependency&gt;
  </code></pre>
  <p>But it doesn't work. When removing the <code>spring-boot-starter-web</code> dependency, it can work well.</p>
