title: My Tomcat connector configured to listen on a port failed to start?
body: <p>I am new to Spring boot, I am trying to build a simple CRUD application, but I get this error when I run my app and I dont know how to solve it. </p>
  
  <p>here is my application.properties file : </p>
  
  <pre><code>server.port = 8079
  spring.datasource.url=jdbc:mysql://localhost:8889/employee?useLegacyDatetimeCode=false&amp;serverTimezone=UTC
  spring.datasource.username = root
  spring.datasource.password = root
  spring.datasource.driver-class-name=com.mysql.jdbc.Driver
  spring.jpa.database-platform = org.hibernate.dialect.MySQL5Dialect
  spring.jpa.generate-ddl=true
  spring.jpa.hibernate.ddl-auto = update
  </code></pre>
  
  <p>But I get the error : </p>
  
  <pre><code>The Tomcat connector configured to listen on port 8079 failed to start. The port may already be in use or the connector may be misconfigured.
  </code></pre>
  
  <p>I changed the port many times but I still get the error so my connector must be misconfigured.</p>
  
  <p>Any help would be much much appreciated.</p>
