在spring mvc中的web.xml中使用“ / *”作为url模式时,我没有重定向到页面。 每当我尝试使用以下url时,我都会在控制器方法中获取记录器,但无法获取该页面。
尝试了网址:http://localhost:8080/mvc-example
记录器:请求主页

尝试了网址:http://localhost:8080/mvc-example/hello
记录器:已请求首页问候页面

这是我的项目结构:
我的控制器:
@Controller
public class HelloController {
@RequestMapping(value = "/hello", method = RequestMethod.GET)
public String printHello(Locale locale, Model model) {
System.out.println("Home hello Page Requested");
model.addAttribute("message", "Hello Spring MVC Framework!");
return "hello";
}
@RequestMapping(value = "/", method = RequestMethod.GET)
public String printAgainHello(Locale locale, Model model) {
System.out.println("Home Page Requested");
model.addAttribute("message", "Hello Again Spring MVC Framework!");
return "helloAgain";
}
}
Web.xml:

当我仅使用“ /”时,它可以按预期工作,但“ / *”无法正常工作。我猜是在犯一些错误。
有人请给我解释一下吗?
谢谢。
