title: Can't find SecurityMockMvcConfigurers
body: <p>I'am trying to write a spring security test as described here <a href="http://docs.spring.io/spring-security/site/docs/4.0.x/reference/htmlsingle/#test-mockmvc-setup" rel="noreferrer">http://docs.spring.io/spring-security/site/docs/4.0.x/reference/htmlsingle/#test-mockmvc-setup</a>. I need to import <code>SecurityMockMvcConfigurers</code> as a static import, but my IDE does not find the class.</p>
  
  <p>My pom.xml looks as follows:</p>
  
  <pre><code>&lt;parent&gt;
      &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
      &lt;artifactId&gt;spring-boot-starter-parent&lt;/artifactId&gt;
      &lt;version&gt;1.4.0.M2&lt;/version&gt;
      &lt;relativePath/&gt; &lt;!-- lookup parent from repository --&gt;
  &lt;/parent&gt;
  
  &lt;properties&gt;
      &lt;project.build.sourceEncoding&gt;UTF-8&lt;/project.build.sourceEncoding&gt;
      &lt;java.version&gt;1.8&lt;/java.version&gt;
  &lt;/properties&gt;
  
  &lt;dependencies&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;
      &lt;dependency&gt;
          &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
          &lt;artifactId&gt;spring-boot-starter-security&lt;/artifactId&gt;
      &lt;/dependency&gt;
  
      &lt;dependency&gt;
          &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
          &lt;artifactId&gt;spring-boot-starter-test&lt;/artifactId&gt;
          &lt;scope&gt;test&lt;/scope&gt;
      &lt;/dependency&gt;
  &lt;/dependencies&gt;
  </code></pre>
  
  <p>Spring Boot 1.4.0.M2 imports Spring Security 4.0.4.RELEASE. I' can't find the class in this release. Which additional dependency do I need? Or what else I haven't considered?</p>
