Question

我想向我的客户数据库添加付款，但是当我添加付款时，我收到此错误“GET NOT SUPPORTED”我不知道问题是什么。你们能帮助我吗？

@Controller
public class PaymentsController {

    @Autowired
    private UsersService usersService;
    @Autowired
    private PaymentsService paymentsService;

    @RequestMapping(value = "/addPayments", method = RequestMethod.POST)
    public String addPayments(HttpServletRequest request, ModelMap map) {
        String user = request.getParameter("userId"); // this is the identifier for the user of this payment
        String transactName = request.getParameter("transactName");
        String paid = request.getParameter("paid");
        String unpaid = request.getParameter("unpaid");
        String balance = request.getParameter("balance");
        String total = request.getParameter("total");
        //.... get all other attributes you've passed from the form through request.getParameter("");

        //next, check whether or not a user with the userId from the screen exists in the db
        Users userObject = usersService.getUsers(user);
        //.getUsersByUserId(user);
        if (userObject != null) {
            // this means that we have a valid user to insert the payment to
            UsersPayments payment = new UsersPayments();
            payment.setUsers(userObject);
            payment.setTransactName(transactName);
            payment.setPaid(paid);
            payment.setUnpaid(unpaid);
            payment.setBalance(balance);
            payment.setTotal(total);
            //....  set the other properties of UsersPayment object

            paymentsService.addPayments(payment);
        }
        else {
            // you have an error right here
        }
        map.put("paymentsList", paymentsService.getAllPayments());
        return "payments";
    }
}

Answer 1

您似乎只有一个处理程序映射，它的POST。使用GET为同一个url路径添加另一个处理程序映射。考虑＆＃34; POST Redirect GET＆＃34;模式也是如此。

HTTP状态405 - 请求方法＆＃39; GET＆＃39;不支持
