The controller annotated with can have custom class argument(s) annotated with Spring MVC, we refer to this as data binding, a common mechanism that saves us from having to parse each form field individually. Later in this article, we'll see a complete example of how to use the employee object to populate the employeeView template. Spring MVC does this behind the scenes before invoking the submit method: = "/addEmployee", method = RequestMethod.POST) In the following code snippet, we'll populate the employee model attribute with data from a form submitted to the addEmployee endpoint. appfuse gives template application on which you can build your own. But this example uses maven, i guess that is not a problem for you. Once present in the model, the arguments fields should populate from all request parameters that have matching names. (I would suggest getting spring 3.1.M2 and hibernate 3.6.x - they are the latest versions) This is a good example to get started with spring+hibernate with annotations. When the annotation isn't present, it should first be instantiated, and then added to the model. When we use the annotation as a method argument, it indicates to retrieve the argument from the model. So far, EVERY page on the internet has only driven me crazy with confusing configurations and bloated code that I did not find portable at all. PS : And yes Spring 3.1+ automatically expose to the model. 86 I have a ReSTFul API written in simple Spring (no Spring Boot, no fancy stuff). I am not going to explain these :) as they each are long answers themselves, so google it for more info. There are other infrastructure beans that are instantiated by these tag ( chained in addition to defaults) like - MappedInterceptor, ConfigurableWebBindingInitializer, SessionFlashManager, ContentNegociationManager etc. The Controller annotation marks this class as Controller. Therefore the request is directly mapped right to the method. To create the controller class, we are using two annotations Controller and RequestMapping. RequestMappingHandlerMapping does both the tasks. These are deprecated in Spring 3.1 and if you use above mentioned tag it will be replaced by -ÄefaultAnnotationHandlerMapping decided which controller to use and the AnnotationMethodHandlerAdapter selected the actual method that handled the request. AnnotationMethodHandlerExceptionResolver.Prior to Spring 3.1 default beans used where Now lets come to what this tag actually does. ( Do not use it if you want backward compatibility, especially if you are using old controller based classes like MultiActionController, SimpleFormController) This tag can be used Spring 3.0+ to enable new feature introduced from Spring 3.0 For example, if spring-webmvc is on the classpath, this annotation flags the application as a web application and activates key behaviors, such as setting up a DispatcherServlet. In this post, I’d love to share what it is and when it is used with some code examples. Next is the web module page, provide the context root of application as spring-mvc. With Spring, we have two options for these configurations, a Java-based and an XML-based way. All we have to do is to define some beans as well as a few parameters. You might have to remove src folder from the list before adding this. As mentioned before, Spring supports us with bootstrapping the Hibernate SessionFactory. On next page, provide the source folder as src/main/java. You don't have to provide mvc:annotation-driven tag to instantiate default beans. You know, Controller is a very popular annotation in Spring framework. Provide name as spring-mvc-example in the next popup page, rest of the things should not required to be changed. Before I provide certain points let me clear up the answer provided by Roy is not accurate.
