Spring如何將jsp的url映射到其各自的控制器？

Question

我正在一個Spring Web項目上工作，我有很多JSP文件和很多控制器，但是我不知道如何做到這一點。

<form:form action="updateCustomer" autocomplete="true"  commandName="customer">

表單自動映射到在其中定義updateCustomer的各個控制器。 還有其他控制器，但是url updateCustomer如何准確地傳遞給相應的控制器。

Customer.jsp文件如下：

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
<%@ taglib uri="http://www.springframework.org/tags" prefix="spring"%>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>

            </div>
            <!-- /container -->
        </section>
    </form:form>

</body>

</html>

控制器文件如下：

    package com.htss.web.controller;

//assume all imports

@Controller
@RequestMapping("/buyer")
public class BuyerController {


    @Autowired
    private BuyerService customerService;

    @Autowired
    private UserService userService;

    @Autowired
    private CommonService commonService;
    @Autowired
    private MessageSource messageSource;

    @RequestMapping(value = "/open/customer")
    public String customerInfo() {
        return "customer";
    }



    @RequestMapping(value = "/edit_profile")
    public String editCustomerProfile(HttpSession session, Model model) {
        Integer buyerId = (Integer) session.getAttribute("entityId");
        BuyerFormBean bean = customerService.retrieveCustomer(buyerId);
        Long userId = (Long) session.getAttribute("userId");
        try {
            UserFormBean user = userService.getUser(userId);
            bean.setUser(user);
        } catch (IllegalAccessException | InvocationTargetException e) {
        }
        model.addAttribute("customer", bean);
        model.addAttribute("countries", commonService.getCountryDropdown());
        model.addAttribute("action", "updateCustomer");
        return "buyerProfile";
    }



    @RequestMapping(value = "/updateCustomer")
    public String updateCustomerProfile(Model model, HttpSession session, BuyerFormBean customer) {

        try {
            if (action == 1 || action == 2) {
                customer = customerService.modifyCustomer(customer);

            }

            }
            catch (Exception e) {
            e.printStackTrace();
            model.addAttribute("error",messageSource.getMessage("msg.Error",null,Locale.US));
        }
        Integer buyerId = (Integer) session.getAttribute("entityId");
        BuyerFormBean bean = customerService.retrieveCustomer(buyerId);
        Long userId = (Long) session.getAttribute("userId");        
        try {
            UserFormBean user = userService.getUser(userId);
            bean.setUser(user);
        } catch (IllegalAccessException | InvocationTargetException e) {
        }

        model.addAttribute("customer", bean);
        model.addAttribute("message",messageSource.getMessage("msg.Success",null,Locale.US));
        return "Customer";
    }


}

現在的問題是，當我單擊“保存”按鈕時，形成的網址是：
http：// localhost：8080 / 82ism / buyer / updateCustomer

這是怎么發生的？ 現在，當我需要某個其他控制器的按鈕時，我需要給出整個URL，如下所示：

${pageContext.request.contextPath}/seller/edit_profile

這個項目一切正常，我只是想了解這個概念。

春天的重點是讓您不必擔心這些東西。 在應用程序中找到jsp的屬性的原因。

spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp

對於形式和方法...並非如此。 您必須按名稱校准的表單，方法被八義映射到url或action

喜歡：

@RequestMapping("/")
or
@RequestMapping(method=RequestMethod.POST)

要從控制器中調用表單的值，您首先必須將表單的字段作為變量將它們綁定到實體模型。 該方法如下所示：

@RequestMapping(method = RequestMethod.POST)    
public String processRegister(@ModelAttribute("userForm") User user,   
Map<String, Object> model) {
    ...
    return "view";
}
