title: What is the difference between a spring request mapping and url mapping?
body: <p>I stumbled across this question after reading the log of my spring boot applicaiton in debug mode. </p>
  
  <p>At startup, the While the spring <a href="http://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/web/servlet/mvc/method/annotation/RequestMappingHandlerMapping.html" rel="noreferrer"><code>RequestMappingHandlerMapping</code></a> is "Looking for request mappings in application context" and finds the resquest mappings defined  on my controllers. Later the <a href="http://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/web/servlet/handler/BeanNameUrlHandlerMapping.html" rel="noreferrer"><code>BeanNameUrlHandlerMapping</code></a> is "Looking for URL mappings in application context" and fails to find one for every bean defined in my context (no URL paths identified)</p>
  
  <p>My question is, what the difference between a request mapping and an url mapping, can someone link a documentation to read what the <code>BeanNameUrlHandlerMapping</code> is looking for?</p>
