The Spring MVC allows you to use the @RequestMapping annotation at the class level. This means we can annotate the controller class with @RequestMapping, as shown in the following code snippet:

    package com.packt.patterninspring.chapter10.bankapp.web.controller; 
 
    import org.springframework.stereotype.Controller; 
    import org.springframework.ui.ModelMap; 
    import org.springframework.web.bind.annotation.RequestMapping; 
    import org.springframework.web.bind.annotation.RequestMethod; 
 
    @Controller 
    @RequestMapping("/") 
    public class HomeController { 
    
     @RequestMapping(method=GET) 
     public String home() { 
         return "home"; 
     } 
   } 

As you have seen in the preceding code, the HomeController class is annotated with the @RequestMapping and @Controller annotations. But the HTTP method is still defined above the handler methods. Class-level mapping is applied with all the handler methods defined under this controller.

After the Spring MVC configuration, we created a controller class with the handler methods. Let's test this controller before moving ahead with more details. In this book, I haven't use any JUnit test cases, so here, I will just run this web application on the Tomcat container. You can see the output on the browser as follows:

In the next section, we'll see how to define the handler methods, and the return type and parameters allowed for the handler methods in Spring MVC.
