The InternalResourceViewResolver will have rules defined to resolve the view names. Notice how we're returning a ModelAndView object – which contains a model map and a view object; both will be used by the View Resolver for data rendering: First, we created a controller called TestController and mapped it to the “/test” path.
THE unique Spring Security education if you’re working with Java today. We have to configure it in web.xml file. The following important points are to be noted about the controller defined above −. (1.0, 1.1, 1.0.1, …), compile -> test -> package(.war) -> install -> deploy, web application의 설정을 위한 deployment descriptor.
