这可能已被问过很多次，但在过去的两天里我一直无法找到具体的答案。使用 Spring 3.2。

我有两种方法。一种用于创建表单，另一种用于发布表单。表单创建工作正常。但是当我尝试发布/提交表单时，我看不到日志语句在该login()方法中被执行，并且我收到一个 404 错误 HTTP Status 404 - /sample/login.

我认为问题是表单无法提交到 URL，但我不知道如何修复映射以使其工作。

如果还有其他需要的文件，请告诉我。BTW 以下示例来自 sprin/mvc-basic 和 spring/petclinic

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import example.domain.User;
import example.service.UserValidator;


@Controller
@RequestMapping(value="/login")
public class LoginFormController {  

   protected final Log logger = LogFactory.getLog(getClass());

   @RequestMapping(method=RequestMethod.GET)
   public String loadForm(Model model) {
        logger.info("LoginFormController login");
        model.addAttribute("user", User.getUserInstance());
        return "login";
   }

   @RequestMapping(method=RequestMethod.POST)
   public String login(@ModelAttribute User user, BindingResult result) {
        logger.info("post");
        new UserValidator().validate(user, result);
        if (result.hasErrors()) {
            return "login";
         } else {
            logger.info("Email Id: " + user.getEmailId());
            //this.clinic.storeOwner(owner);
            //status.setComplete();
            return "redirect:/landing/" + user.getEmailId();
         }
   }
}

似乎您已将*.htmURL 映射到DispatcherServlet（从 猜测/signup.htm）。将表单标记中的操作更改为，login.htm而不是login：

<form:form method="post" modelAttribute="user" action="login.htm">
