This is not strictly necessary when {@link RequestMapping} is * applied at the type level (since such a handler usually implements the * {@link org.springframework.web.servlet.mvc.Controller} interface). However, * {@link Controller} is required for detecting {@link RequestMapping} annotations * at the method level if {@link RequestMapping} is not present at the type level. * * <p>NOTE: Method-level mappings are only allowed to narrow the mapping * expressed at the class level (if any). HTTP paths need to uniquely map onto * specific handler beans, with any given HTTP path only allowed to be mapped * onto one specific handler bean (not spread across multiple handler beans). * It is strongly recommended to co-locate related handler methods into the same bean. * * <p>The {@link AnnotationMethodHandlerAdapter} is responsible for processing * annotated handler methods, as mapped by this HandlerMapping. For * {@link RequestMapping} at the type level, specific HandlerAdapters such as * {@link org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter} apply. * * @author Juergen Hoeller * @author Arjen Poutsma * @since 2.5 * @see RequestMapping * @see AnnotationMethodHandlerAdapter */ public class DefaultAnnotationHandlerMapping extends AbstractDetectingUrlHandlerMapping { private boolean useDefaultSuffixPattern = true; private final Map<Class, RequestMapping> cachedMappings = new HashMap Other Spring Framework examples (source code examples)Here is a short list of links related to this Spring Framework DefaultAnnotationHandlerMapping.java source code file: |
