You are creating a Web application for the book shop by using Spring MVC. When a user sends a request for theURL, /SearchBook.htm page in this Web application, the request needs to be handled by theSearchBookController class defined in the controller package of the Web application. For this, you used thefollowing code snippet:<beans> <bean id="ControllerHandlerMapping" class=org.springframework.web.servlet.mvcsupport,SimpleUrlHandlerMapping"/><bean class="controller SearchBookController"></beans> However, the preceding code snippet does not forward the request to the SearchBookController class. Analyze theproblem and provide the correct code snippet.

The code snippet provided in the question is incorrect because the `SimpleUrlHandlerMapping` bean is not properly configured to handle the URL mapping for the `SearchBookController`. To correctly map the URL `/SearchBook.htm` to the `SearchBookController`, you should use the following code snippet:
```xml
<beans>
<bean id="handlerMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="/SearchBook.htm">searchBookController</prop>
</props>
</property>
</bean>
<bean id="searchBookController" class="controller.SearchBookController"/>
</beans>
```
In this code snippet, we are using the `SimpleUrlHandlerMapping` bean to map the URL `/SearchBook.htm` to the `searchBookController` bean, which is an instance of the `SearchBookController` class. The `handlerMapping` bean is configured with a `mappings` property that contains a `props` element with a single URL mapping for `/SearchBook.htm`. The `searchBookController` bean is defined as an instance of the `SearchBookController` class and is mapped to the `searchBookController` bean ID. This configuration ensures that requests to the `/SearchBook.htm` URL are handled by the `SearchBookController` class.
