我知道有很多问题都有相同的问题，但是经过3天的研究，我无法解决问题。
如果有人在其他地方找到答案，请随时将其标记为重复并带我到那里。
我正在尝试在控制器中映射请求，然后将我的默认视图文件夹下的子文件夹重定向。但是，我遇到了404错误。

如您所见，我的默认视图文件夹是Web-Inf/Views。到目前为止，一切都很好。我做了这样的子文件夹：
WEB-INF/
|-views/
|-admin/
|-default.jsp
在我的控制器中，我无法访问Web-Inf/views/admin/default.jsp，因为我会遇到此404错误。
我的控制器：
package br.com.sigcom.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class SpringController {
@RequestMapping(value = {"", "/", "home", "default", "index"})
public String redirectDefaultPage() {
return "default";
}
@RequestMapping("admin")
public String redirectAdminPage() {
return "admin/default";
}
}
我尝试了很多，搜索了很多，但是没有成功。我知道这一定是一个简单的细节，但我很累。预先感谢您！

我尝试了一个设置一个带有相同设置的项目，除非没有过滤器，过滤器映射，错误页面，web.xml中的侦听器，我可以访问没有404的访问URL。
控制器也能够解析模板。您是否也使用上下文路径正确输入URL？例如http：//localhost：8080/ sigcom /admin
我已经使用您的代码创建了一个新项目。但最后，我得到了正确的东西。也许您可以像一楼所说的那样检查您的URL。
已解决。当你们没有过滤器的情况下运行时，我评论了我的工作。现在我知道该怎么办。感谢您的帮助，伙计们！
