I am new to Spring and start with simple tutorials. I define a simple jsp and Controller, then match its xml document and run it, but only what I saw is my wev page without the values that I passed in the controller:
@Controller public class HomeController { @Autowired private ExampleService exampleService; @RequestMapping(value = "/", method = RequestMethod.GET) public String home(Model model) { model.addAttribute("serverTime", exampleService.getSystemTime()); model.addAttribute("appVersion", exampleService.getAppVersion()); return "home"; } } @Component public class ExampleService { @Value("#{appProperties.appVersion}") private String appVersion; /** * Returns formatted system time. * * @return */ public String getSystemTime() { DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG, DateFormat.LONG); return dateFormat.format(new Date()); } public String getAppVersion() { return appVersion; } } <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>Spring</display-name> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring-config.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <servlet> <servlet-name>appServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/servlet-context.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>appServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>

I learned a few guides and read the web part of the official documentation that is relevant to my work, but I still do not understand where the problem is in my code.
I am stuck. If you have any ideas, share it with me. Thank you
