我正在尝试在 Eclipse 中设置一个 spring mvc 项目。我创建了一个动态 Web 项目，并创建了源代码和配置文件。当我在由 eclipse 启动的 tomcat 上运行项目时，我总是遇到 404 错误。这是我的弹簧配置文件：

如果要打开名称为“index.jsp”的页面：在配置中添加以下行（/WEB-INF/jsp 中必须有 index.jsp 文件）：

<mvc:view-controller path="/" view-name="index" />

如果你想在页面中添加一些对象，你必须编写简单的类，使用 @Controller 注释对其进行注释并添加带有映射的方法：

@Controller
public class IndexController {

    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String showRegistration(Model model) {
        Integer usersCount = 1; // replace with service code
        model.addAttribute("usersCount", usersCount);
        return "index";
    }
}
