我认为我所做的一切都是正确的，但我的所有页面（如 /main/signup.htm）上仍然出现 404。我有点迷失在这里可能缺少的东西（与xml配置等效的东西，但我想用注释来做到这一点 - 这是一个教育项目，我团队的其他成员对spring等更不熟悉比我现在，所以我认为至少在 java 文件中进行一些配置将有助于缓解它们）。

MainController（省略导入）：

@Controller
@RequestMapping("/main")
public class MainController {

    @RequestMapping(value="/default.htm", method=RequestMethod.GET)
    public String defaultAfterLogin(HttpServletRequest request) {
        if(request.isUserInRole("ADMIN")) {
            return "redirect:/main/admin.htm";
        } else {
            return "redirect:/main/signup.htm";
        }
    }
    @RequestMapping(value="/signup.htm", method=RequestMethod.GET)
    public ModelAndView signup() {
        return new ModelAndView("signup");
    }

    @RequestMapping(value="/admin.htm", method=RequestMethod.GET)
    public ModelAndView admin() {
        return new ModelAndView("admin");
    }

}

将<context:component-scan base-package="your.package.controller" />标签添加到您的springapp-servlet.xml

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:mvc="http://www.springframework.org/schema/mvc"

    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans

    <mvc:annotation-driven />

    <context:component-scan base-package="your.package.controller" />

    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
