public class SimpleUrlHandlerMapping extends AbstractUrlHandlerMapping
HandlerMapping
interface to map from URLs to request handler beans. Supports both mapping to bean
instances and mapping to bean names; the latter is required for non-singleton handlers.
The "urlMap" property is suitable for populating the handler map with bean references, e.g. via the map element in XML bean definitions.
Mappings to bean names can be set via the "mappings" property, in a form
accepted by the java.util.Properties
class, like as follows:
/welcome.html=ticketController
/show.html=ticketController
The syntax is PATH=HANDLER_BEAN_NAME
.
If the path doesn't begin with a slash, one is prepended.
Supports direct matches (given "/test" -> registered "/test") and "*"
matches (given "/test" -> registered "/t*"). Note that the default is
to map within the current servlet mapping if applicable; see the
"alwaysUseFullPath"
property for details.
For details on the pattern options, see the
AntPathMatcher
javadoc.

Useful for specifying entries directly, for example via "urlMap[myKey]". This is particularly useful for adding or overriding entries in child bean definitions.
