      public class ControllerBeanNameHandlerMapping
      extends AbstractControllerUrlHandlerMapping

  Implementation of `HandlerMapping` that follows a simple convention for generating URL path mappings from the bean names of registered `Controller` beans as well as `@Controller` annotated beans.

  This is similar to `BeanNameUrlHandlerMapping` but doesn't expect bean names to follow the URL convention: It turns plain bean names into URLs by prepending a slash and optionally applying a specified prefix and/or suffix. However, it only does so for well-known `controller types`, as listed above (analogous to `ControllerClassNameHandlerMapping`).

  - ### Method Detail

    - #### setUrlPrefix

          public void setUrlPrefix(String urlPrefix)

      Set an optional prefix to prepend to generated URL mappings.

      By default this is an empty String. If you want a prefix like "/myapp/", you can set it for all beans mapped by this mapping.

    - #### setUrlSuffix

          public void setUrlSuffix(String urlSuffix)

      Set an optional suffix to append to generated URL mappings.

      By default this is an empty String. If you want a suffix like ".do", you can set it for all beans mapped by this mapping.

    - #### buildUrlsForHandler

          protected String[] buildUrlsForHandler(String beanName,
                                                 Class<?> beanClass)

      Description copied from class: `AbstractControllerUrlHandlerMapping`
      Abstract template method to be implemented by subclasses.
      Specified by:
        `buildUrlsForHandler` in class `AbstractControllerUrlHandlerMapping`
      Parameters:
        `beanName` - the name of the bean
        `beanClass` - the type of the bean
      Returns:
        the URLs determined for the bean

    - #### generatePathMapping

          protected String generatePathMapping(String beanName)

      Prepends a '/' if required and appends the URL suffix to the name.
