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"; 
      } 

   }

The following definitions explain the code in detail:

  • @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 incorporated into the model will be available for use in the View.
  • model.put("name", "XYZ"): This adds an attribute with the name name and the XYZ value to the model.
