1)I have a web.xml with this content
<
servlet>
<servlet-name>springapp</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springapp</servlet-name>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>
2) I have a file SpringappController.java
public class SpringappController implements Controller {
/** Logger for this class and subclasses */
protected final Log logger = LogFactory.getLog("SpringappController.class");
private ProductManager prodMan;
public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String now = (new Date()).toString();
logger.info("SpringappController - returning hello view"+now);
Map myModel = new HashMap();
myModel.put("now", now);
myModel.put("products", getProductManager().getProducts());
return new ModelAndView("hello", "model", myModel);
}
public void setProductManager(ProductManager pm) {
prodMan = pm;
}
public ProductManager getProductManager() {
return prodMan;
}
}
My Doubt: In the web.xml <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> is called to handle requests, but indirectly the SpringappController class handles the requests.
How does the servlet container know that SpringappController is the DispatcherServlet?.
