title: Spring Boot TLS v1.2 enabled but package exchange not deteced with Wireshark
body: <p>I have enabled Spring Boot SSL/TLS with the following properties in the <strong>application.properies</strong> file:</p>
  
  <pre><code>server.port=8443
  server.ssl.key-store=classpath:security/keystore.p12
  server.ssl.key-store-password=springboot
  server.ssl.key-store-type=PKCS12
  server.ssl.key-alias=tomcat
  server.ssl.protocol=TLSv1.2
  server.ssl.enabled=true
  security.require-ssl=true
  server.ssl.ciphers=TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384,TLS_ECDHE-RSA-AES256-GCM-SHA384,TLS_ECDHE-ECDSA-CHACHA20-POLY1305,TLS_ECDHE-RSA-CHACHA20-POLY1305,TLS_ECDHE-ECDSA-AES128-GCM-SHA256,TLS_ECDHE-RSA-AES128-GCM-SHA256,TLS_ECDHE-ECDSA-AES256-SHA384TLS_ECDHE-RSA-AES256-SHA384,TLS_ECDHE-ECDSA-AES128-SHA256,TLS_ECDHE-RSA-AES128-SHA256
  </code></pre>
  
  <p>and I have also configured the HTTP connector to redirect traffic request on port 8080 to port 8443 with this lines in a configuration class
  </p>
  
  <pre><code>@Bean
      public EmbeddedServletContainerFactory servletFactory(){
          TomcatEmbeddedServletContainerFactory tomcat = new TomcatEmbeddedServletContainerFactory() {
  
              @Override
              protected void postProcessContext(Context context){
  
                  SecurityConstraint securityConstraint = new SecurityConstraint();
                  securityConstraint.setUserConstraint("CONFIDENTIAL");
                  SecurityCollection collection = new SecurityCollection();
                  collection.addPattern("/*");
                  securityConstraint.addCollection(collection);
                  context.addConstraint(securityConstraint);
              }
          };
  
          tomcat.addAdditionalTomcatConnectors(initiateHttpConnector());
          return tomcat;
      }
  
      private Connector initiateHttpConnector() {
  
          Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
          connector.setScheme("http");
          connector.setPort(8080);
          connector.setSecure(false);
          connector.setRedirectPort(8443);
          return connector;
      }
  </code></pre>
  
  <p>Everything works fine but if I scan my traffic using <strong>Wireshark</strong> I can't find TLSv1.2 protocol packages but only TCP packages. 
  Is this the correct behavior or is there anything wrong?</p>
  
  <p>Thanks to all.</p>

  These are the screenshots from Wireshark:
