请慷慨和告诉我们为什么我有这个愚蠢的问题
一切正常，没有映射！但我有一个简单的问题。我已经设置了一个父映射@“ / hello”并子映射了一个方法@“ / showForm”，Dispatcher被设置为“ /” 但是我得到404 （参见代码图3）。我找不到要解决的问题[[类似。
请参阅下面的代码和我的设置的标签
Controller图1
@Controller
@RequestMapping("/hello")
public class HelloWorldController {
@RequestMapping("/showForm")
public String showForm() {
return "hello-world";
}

/hello的请求将由whatever()处理，而对/hello/showForm的请求将由showForm()处理
