Spring MVC не может загрузить файлы .jsp, но возвращает ошибку 404

0 голосов
/ 05 июня 2019

Я изучаю Spring MVC из курса множественного взгляда (создание веб-приложения с использованием Spring mvc) с файлами упражнений.Используя оригинальный проект, я обнаружил, что мой проект не может загрузить файлы .jsp в каталог ресурсов.Префикс и суффикс были настроены в bankAppContext.xml, но проект никогда не сможет загрузить правильный файл .jsp.

Для любопытства я создал новый файл "index.html" прямо под этим проектом.Оказалось, что когда я запустил свой локальный сервер Tomcat, он загрузил этот «index.html» в качестве домашней страницы независимо от настроек префикса и суффикса, как я намеревался загрузить файлы .jsp.Если у меня нет этого «index.html», домашняя страница возвращает «404 Not Found - исходный сервер не нашел текущего представления для целевого ресурса или не хочет раскрыть, что он существует».Та же ошибка 404 для других конечных точек, таких как "/new".

Моя версия Intellij Ultimate: 2019.1.2, Java 1.8.0-191, Tomcat 7.0.94.Я также прилагаю свои скриншоты и коды.

AccountController.java 

package com.ps.springmvc.psbankapp.controllers;

import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import com.ps.springmvc.psbankapp.model.Account;

@Controller
public class AccountController {

    @RequestMapping("/")
    public String showHomePage() {
        return "index";
    }

    @RequestMapping("/new")
    public String newAccount() {
        return "newAccount";
    }

    @RequestMapping("/showAccount")
    public String showAccount() {
        return "showAccount";
    }

    @RequestMapping(value="/saveAccount",method=RequestMethod.POST)
    public String saveAccount(Model model,HttpServletRequest request) {
        String acNo = request.getParameter("accountNo");
        String customerName = request.getParameter("accountHolderName");
        String balance = request.getParameter("balance");

        /*model.addAttribute("accountNumber", acNo);
        model.addAttribute("accountHolderName", customerName);
        model.addAttribute("balance", balance); */

        Account account = new Account();
        account.setAccountNo(Integer.parseInt(acNo));
        account.setAccountHolderName(customerName);
        account.setBalance(Integer.parseInt(balance));

        model.addAttribute("account",account);
        return "showAccount";
    }
}
