Question

我正在从一个多元化的课程（使用spring mvc构建Web应用程序）及其练习文件研究Spring MVC。通过使用原始项目，我发现我的项目无法在资源目录中加载.jsp文件。前缀和后缀已在bankAppContext.xml中设置，但是该项目永远无法加载正确的.jsp文件。

出于好奇，我在该项目下创建了一个新文件“ index.html”。事实证明，当我启动本地Tomcat服务器时，无论打算加载.jsp文件的前缀和后缀设置如何，它都将“ index.html”作为主页加载。如果我没有此“ index.html”，则主页返回“ 404未找到-源服务器未找到目标资源的当前表示或不愿意透露该资源的存在”。与其他端点（例如“ / new”）相同的404错误。

我的Intellij Ultimate版本是2019.1.2，Java 1.8.0-191，Tomcat 7.0.94。我还要附上我的屏幕截图和代码。

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";
    }
}

这是我的启动日志，它以“ index.html”作为主页启动。
