java - jsp servlet 无法使用 intelling ide 和 tomcat 505 内部错误服务器显示

问题描述

即使我已经使用 servlet 控制器配置了病房爆炸和 tomcat 服务器，我也无法打开我的 jsp 文件。我试图查看 stackoverflow 和其他网站中的不同错误，但找不到合适的错误解决程序。

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.List;

public class ControleurServlet extends HttpServlet {
    private IAccountDAO account;

    @Override
    public void init()  {
        account = new AccountDAOImpl();
    }

    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        String path = req.getServletPath();
        if (path.equals("/index.php")) {
            req.getRequestDispatcher("Accounts.jsp").forward(req, resp);
        }
        else if (path.equals("/search.php")){
            String keyWord=req.getParameter("keyWord");
            AccountModel model=new AccountModel();
            model.setKeyword(keyWord);
            List<Account> accounts= account.accountsValues("%"+keyWord+"%");
            model.setAccounts(accounts);
            req.setAttribute("model",model);
            req.getRequestDispatcher("Accounts.jsp").forward(req,resp);
        }
 } 
}

这是我的jsp文件

<%@ page contentType="text/html;charset=UTF-8" language="java" %>

    <div class="panel panel-primary">
        <div class="panel-heading">Search Users:</div>
        <div class="panel-body">
            <form action="search.php" method="get">
                <label>Keyword</label>
                <input type="text" name="keyWord">
                <button type="submit" class="btn btn-primary">Search</button>
            </form>
            <table class="table">
                <tr>
                    <th>User_Id</th><th>Creation_Date</th><th>Username</th><th>Password</th>
                </tr>
                <c:forEach items="${model.account}" var="acc">
                    <tr>
                        <td>${acc.user_id}</td>
                        <td>${acc.creation_date}</td>
                        <td>${acc.username}</td>
                        <td>${acc.password}</td>
                        <td><a onclick="return confirm("Are you sure?")" href="delete.php?id=${acc.user_id}">delete</a> </td>
                        <td><a href="Edit.php?id=${acc.user_id}">Edit</a> </td>
                    </tr>
                </c:forEach>
            </table>
        </div>
    </div>
</div>
</body>
</html>

尝试打开我的时，它一直向我显示 505 错误http://localhost:3030/Banque_war_exploded/index.php，这也是我的web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <servlet-name>cs</servlet-name>
