  Description:
  
  Failed to bind properties under 'server' to org.springframework.boot.autoconfigure.web.ServerProperties:
  
      Property: server
      Value: 
      Origin: class path resource [application.properties]:2:0
      Reason: No converter found capable of converting from type [java.lang.String] to type [@org.springframework.boot.context.properties.ConfigurationProperties org.springframework.boot.autoconfigure.web.ServerProperties]
  
  Action:
  
  Update your application's configuration
  </code></pre>
  
  <p>My application.properties file look like this:</p>
  
  <pre><code>server:
    port: ${PORT:9191}
  
  spring:
  
    datasource:
      url: jdbc:sqlserver://PC382682:1433;databaseName=imvenkat 
      username: imvenkat
      password: imvenkat
      driverClassName: com.microsoft.sqlserver.jdbc.SQLServerDriver
  </code></pre>
  
  <p>I know the issue is related to Spring boot, but how should I change my application.properties file to address this issue?</p>
