我想为我的应用程序构建一个注册和登录模块，但遇到了标题中的错误。
我的登录. html

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
  <meta charset="UTF-8">
  <title>Login</title>
</head>
<body>

<h1>Login</h1>
<form th:action="@{/login}" th:object="${login}" method="post">
  Username: <input type="text" th:field="*{username}"><br/>
  <p th:if="${#fields.hasErrors('username')}" th:errors="*{username}"></p>
  Password: <input type="password" th:field="*{password}"><br/>
  <p th:if="${#fields.hasErrors('password')}" th:errors="*{password}"></p>

到目前为止，我可能尝试了所有通过谷歌找到的解决方案，但没有得到一个解决方案。这是我第一次使用像Lombok和HttpServletResponse这样的技术。我知道我不能用java示例化一个接口，但我不知道如何解决它。提前感谢你们。

Sping Boot 3（和Spring Framework 6）需要Jakarte EE 10的基线。您不能将其用于Java EE或低于Jakarte EE 10的版本。
您必须从pom.xml中删除对jakarta.servlet-api的显式依赖。Java Servlet 4低于基线，特别是仍然使用以javax.servlet开头的包名称。
如果你删除了显式的依赖关系，Spring将传递性地拉入正确的依赖关系，然后你需要用jakarta替换javax来替换所有以javax.servlet开头的导入，例如：

import jakarta.servlet.http.Cookie;
import jakarta.servlet.http.HttpServletResponse;
