Spring HandlerMapping Types

HandlerMapping is responsible for translating a URL pattern to a controller. There are several URL mappers:

• BeanNameUrlHandlerMapping: Maps a URL to a bean based on the name of the controller's bean, as defined in the bean's XML definition.
• SimpleUrlHandlerMapping: Maps a URL to a bean based on a list of properties. (In Listing 2, the SimpleUrlHandlerMapping class is used to map /home.htm to the bean with the ID of homePageController.)
• ControllerClassNameHandlerMapping: Maps a URL to a bean based on the bean's class name. For example, HomePageController would be mapped to /homePage*, such as /home.htm.
• ControllerBeanNameHandlerMapping: Similar to the BeanNameUrlHandlerMapping mapper, but does not expect bean names to follow the URL convention. Also supports Controller annotations.
• CommonsPathMapHandlerMapping: Maps URLs to a controller based on Jakarta Commons Attributes metadata.
• DefaultAnnotationHandlerMapping: Maps URLs to a controller for methods that implement the RequestMapping annotation.
