如何在spring mvc的1个控制器类中分离2个POST和2个GET方法

Question

我正在开发具有购买产品交易的网络应用程序，并且该交易需要客户数据。所以在那个交易表单中，我添加了一个模态表单供用户添加新的客户数据。

目前这里是这样的：

link to open the add new customer modal form

modal form to add customer

这里是我的完整控制器类：

@Controller

公共类 InvoiceProductController {

private static final Logger logger = LoggerFactory.getLogger(HomeController.class);

@Autowired
private MsEmployeeService msEmployeeService;

@Autowired
private MsCustomerService msCustomerService;

@Autowired
CustomerFormValidator customerFormValidator;

@Autowired
private MsLocationService msLocationService;

@Autowired
private MsReligionService msReligionService;

// Set a form validator
@InitBinder("msCustomer")
protected void initBinder(WebDataBinder binder) {
    binder.setValidator(customerFormValidator);
}

@RequestMapping(value = "/trproduct", method = RequestMethod.GET)
public ModelAndView trproduct(Locale locale, HttpSession session) {
    ModelAndView mav = new ModelAndView("entryinvoiceproduct");
    MsUser loggedInUser = (MsUser) session.getAttribute("loggedInUser");
    List<MsEmployee> msEmployee = msEmployeeService.findEmployeeByJobsAndLocation("BEAUTY CONSULTANT",
            (short) loggedInUser.getMsLocation().getId());

    List<MsCustomer> msCustomer = msCustomerService.findAll();

    mav.addObject("listCustomer", msCustomer);
    mav.addObject("beautyConsultant", msEmployee);
    mav.addObject("defaultLocation", loggedInUser);
    return mav;
}

@RequestMapping(value = "/trproduct", method = RequestMethod.POST)
public String saveCustomer(@ModelAttribute("customerForm") @Validated MsCustomer msCustomer, BindingResult result,
        Model model, final RedirectAttributes redirectAttributes) {

    logger.debug("saveOrUpdateUser() : {}", msCustomer);

    if (result.hasErrors()) {
        populateDefaultModel(model);
        return "/trproduct";
    } else {

        // Add message to flash scope
        redirectAttributes.addFlashAttribute("css", "success");
        if (msCustomer.isNew()) {
            redirectAttributes.addFlashAttribute("msg", "User added successfully!");
        } else {
            redirectAttributes.addFlashAttribute("msg", "User updated successfully!");
        }

        msCustomerService.persist(msCustomer);

        // POST/REDIRECT/GET
        return "/trproduct";
        // POST/FORWARD/GET
        // return "user/list";

    }
}

// show add customer form
@RequestMapping( method = RequestMethod.GET)
public String showAddCustomerForm(Model model, HttpSession session) {

    logger.debug("showAddCustomerForm()");

    MsCustomer msCustomer = new MsCustomer();

    MsUser loggedInUser = (MsUser) session.getAttribute("loggedInUser");

    msCustomer.setUpdateUserId(loggedInUser.getId());
    msCustomer.getMsLocation().setId(loggedInUser.getMsLocation().getId());

    model.addAttribute("customerForm", msCustomer);

    populateDefaultModel(model);

    return "";
}

private void populateDefaultModel(Model model) {

    List<MsLocation> msLocation = msLocationService.findAll();
    model.addAttribute("locationList", msLocation);

    List<MsReligion> msReligion = msReligionService.findAll();
    model.addAttribute("religionList", msReligion);

}

}

这里是我的 jsp，在其中调用模态表单：

		//		$("body").on("click", ".use-address", function() {

		//			var name = $(this).closest("tr").find(".custname").text();

我感到困惑的是，在控制器类中使用模态表单时，我无法分隔 @RequestMapping 值，因为该值将始终为“/trproduct”。在这个控制器类中，我想保存 2 个不同的表（SlInvoiceHdr 和 MsCustomer），但具有相同的 @RequestMapping 值。

我正在为添加客户模式使用相同的 jsp。

我怎样才能在我的控制器中做到这一点？

谢谢

Answer 1

将预期参数添加到您的请求映射中

@RequestMapping( method = RequestMethod.GET , params = { "expectedparam" })

1个控制器，2个方法，requestMapping相同，但参数不同

@RequestMapping(value = "/trproduct", method = RequestMethod.GET) public ModelAndView trproduct(Locale locale, HttpSession session) {

秒：

@RequestMapping( method = RequestMethod.GET, params = { "newform" }) public String showAddCustomerForm(Model model, HttpSession session) {

但是你必须在你的url中添加参数“newform”，比如/trproduct?newform=true
