public class SimpleUrlHandlerMapping
extends AbstractUrlHandlerMapping
```
Implementation of the HandlerMapping interface that maps 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, 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 "*" pattern 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 on the pattern options, see the AntPathMatcher javadoc.

- Constructor Detail
  - SimpleUrlHandlerMapping
```
public SimpleUrlHandlerMapping()
```
    Create a SimpleUrlHandlerMapping with default settings.
  - SimpleUrlHandlerMapping
```
public SimpleUrlHandlerMapping(Map<String,?> urlMap)
```
    Create a SimpleUrlHandlerMapping using the supplied URL map.
    Parameters:
    urlMap - map with URL paths as keys and handler beans (or handler bean names) as values
    Since:
    5.2
    See Also:
    setUrlMap(Map)
  - SimpleUrlHandlerMapping
```
public SimpleUrlHandlerMapping(Map<String,?> urlMap,
                               int order)
```
    Create a SimpleUrlHandlerMapping using the supplied URL map and order.
    Parameters:
    urlMap - map with URL paths as keys and handler beans (or handler bean names) as values
    order - the order value for this SimpleUrlHandlerMapping
    Since:
    5.2
    See Also:
    setUrlMap(Map), AbstractHandlerMapping.setOrder(int)
- Method Detail
  - setMappings
```
public void setMappings(Properties mappings)
```
    Map URL paths to handler bean names. This is the typical way of configuring this HandlerMapping.
    Supports direct URL matches and Ant-style pattern matches. For syntax details, see the AntPathMatcher javadoc.
    Parameters:
    mappings - properties with URLs as keys and bean names as values
    See Also:
    setUrlMap(java.util.Map<java.lang.String, ?>)
  - setUrlMap
```
public void setUrlMap(Map<String,?> urlMap)
```
    Set a Map with URL paths as keys and handler beans (or handler bean names) as values. Convenient for population with bean references.
    Supports direct URL matches and Ant-style pattern matches. For syntax details, see the AntPathMatcher javadoc.
    Parameters:
    urlMap - map with URLs as keys and beans as values
    See Also:
    setMappings(java.util.Properties)
  - getUrlMap
```
public Map<String,?> getUrlMap()
```
    Allow Map access to the URL path mappings, with the option to add or override specific entries.
    Useful for specifying entries directly, for example via "urlMap[myKey]". This is particularly useful for adding or overriding entries in child bean definitions.
  - initApplicationContext
```
public void initApplicationContext()
                            throws BeansException
```
    Calls the registerHandlers(java.util.Map<java.lang.String, java.lang.Object>) method in addition to the superclass's initialization.
    Overrides:
    initApplicationContext in class AbstractHandlerMapping
    Throws:
    ApplicationContextException - in case of initialization errors
    BeansException - if thrown by ApplicationContext methods
    See Also:
    AbstractHandlerMapping.extendInterceptors(java.util.List), AbstractHandlerMapping.initInterceptors()
  - registerHandlers
```
protected void registerHandlers(Map<String,Object> urlMap)
                         throws BeansException
```
    Register all handlers specified in the URL map for the corresponding paths.
    Parameters:
    urlMap - a Map with URL paths as keys and handler beans or bean names as values
    Throws:
    BeansException - if a handler couldn't be registered
    IllegalStateException - if there is a conflicting handler registered
