Spring MVC controller

Let's create a simple Controller. Consider the following example controller:

    @Controller 
    public class BasicModelMapController { 
      @RequestMapping(value = "/welcome-model-map") 
      public String welcome(ModelMap model) { 
        model.put("name", "XYZ"); 
      return "welcome-model-map"; 
     } 
   }

A few important things to note are as follows:

• @RequestMapping(value = "/welcome-model-map"): The URI mapped is /welcome-model-map.
• public String welcome(ModelMap model): The new parameter added is ModelMap model. Spring MVC will instantiate a model and make it available for this method. The attributes put into the model will be available for use in the view.
• model.put("name", "XYZ"): This adds an attribute with the name name and XYZ value to the model.
