java - spring中如何在html和jsp页面之间导航

Question

我在 WEB-INF 目录中有一个名为 kind.html 的 Html 页面，在 WEB-INF 文件夹中有另一个名为 Registration.jsp 的 jsp 页面。我需要将此 Registration.jsp 页面放入 WEB-INF 目录中，这样，如果用户尝试通过键入其 URL 来访问它，则无法访问该页面。所以我的问题是如何使用名为 home 的链接从 kind.html 导航到 Registration.jsp 我是新手，谢谢。下面是我的代码片段和 png 文件

kind.html...................................................... ..

<li class='active'><a href='kind.html'><span>Home</span></a></li>
<li class='has-sub'><a href="registration.jsp"><span>Register</span></a>

@RequestMapping(value="/registration",method = RequestMethod.POST)
    public @ResponseBody
    String firstRegistration(HttpServletRequest req,
            HttpServletResponse response) {
        response.setContentType("text/html");

        RegistrationModel registrationModel = new RegistrationModel();
        registrationModel.setFirstName(req.getParameter("first_name"));
        System.out.println("controller " + req.getParameter("first_name") );
        registrationModel.setLastName(req.getParameter("last_name"));
        registrationModel.setPassword(req.getParameter("password"));
        registrationModel.setEmailID(req.getParameter("email"));
        System.out.println("controller email " + req.getParameter("email"));
        SimpleDateFormat format = new SimpleDateFormat("yyyy-mm-dd");
        try {
            Date date = format.parse(req.getParameter("BirthDate"));
            registrationModel.setDOB(date);
        } catch (Exception e) {
            e.printStackTrace();
        }
        String phoneno=req.getParameter("phoneNo");
        Integer phoneNo = Integer.parseInt(phoneno);
        System.out.println("phone no ...."+phoneNo);
        registrationModel.setPhoneNo(phoneNo);
        registrationModel.setGender(req.getParameter("gender"));
        String age=req.getParameter("Age");
        Long AGE = Long.parseLong(age);
        registrationModel.setAge(AGE);
        registrationModel.setAvtar(req.getParameter("Avtar"));
        System.out.println("avtar"+ req.getParameter("Avtar"));

        Address address = new Address();
        address.setAddressline(req.getParameter("Full-Address"));
        address.setCity(req.getParameter("city"));
        address.setLandmark(req.getParameter("landmark"));
        address.setState(req.getParameter("state"));
        String zipCode =req.getParameter("Zipcode");
        Long zipcode = Long.parseLong(zipCode);
        address.setZipcode(zipcode);
        registrationModel.setAddress(address);

        registrationService.resgistration(registrationModel);

        return "registration.jsp";

    }

第一个调用你的页面的html是静态的，所以你可以使用mvc资源“”，对于jsp，你必须使用ViewResolver，对于jSTL，在其配置中使用InternalResourceViewResolver:

<bean id="viewResolver"
          class="org.springframework.web.servlet.view.InternalResourceViewResolver" >
          <property name="prefix">
              <value>/WEB-INF/view/</value>
           </property>
          <property name="suffix">
             <value>.jsp</value>
          </property>
</bean>

然后在你的 Controller 中使用

return "registration";

您还需要方法来处理 GET 请求并更改以下行

<li class='has-sub'><a href="registration"><span>Register</span></a>

如果您使用 Spring boot，您会发现这些配置是自动化的。
