jsp - Spring Web MVC在intellij中无法访问jsp文件

Question

我已经在 INTELLIJ ide 中配置了一个 spring web MVC 项目。我遵循的教程说 localhost:8080/dispatcher/hello 将显示 hello.jsp。但是在浏览器中我发现“找不到文件”。我已经检查了很多类似的问题，但没有一个对我有用。启动服务器后显示 index.jsp 并且服务器是 tomat。 Project Structure

你好 Controller

@Controller
@RequestMapping("/hello")
public class HelloController {

    @RequestMapping(method = RequestMethod.GET)
    public String printHello(ModelMap model) {
        model.addAttribute("message", "Hello Spring MVC Framework!");
        return "hello";
    }

}

我觉得..

你会如何换行

<servlet-mapping>
   <servlet-name>dispatcher</servlet-name>
   <url-pattern>/</url-pattern>
</servlet-mapping>

如果你想像“*.jsp”那样使用，你应该使用 <jsp-config>或者...您的 WAS 容器设置。(因为，如果您在 Webapp 中键入 <servlet-mapping>，WAS 容器的设置将被忽略)
