java - 为什么 Spring Boot 会生成一个无法为其单元测试加载上下文的项目？
问题描述
我对 Spring Boot 还很陌生，所以如果这个问题已经在其他地方得到有效回答，请原谅我，因为我仍在学习所涉及的术语。
我已经在我的新笔记本电脑上设置了 Spring Tool Suite 和 Open JDK 14，我正在尝试创建一些基本项目并尝试一些教科书示例来探索 Spring Boot 的能力。当我尝试使用 Maven 运行包任务时，我遇到了很多测试和构建问题，通常以 ClassNotFoundException 的形式出现。此类问题的一些论坛答案表明 POM 文件中缺少依赖项，因此 Maven 不知道在何时何地需要安排依赖项。为了弄清楚我哪里出错了，我从一个新生成的项目重新开始，并计划从那里扩展。但是，即使在执行单元测试时，这也会给我一个 ClassNotFoundException 。
我用来重现此问题的步骤：
- 启动一个新的 Spring Boot 项目。我正在关注的书籍示例说选择 web、thymeleaf 和 dev 工具作为依赖项。
- 项目生成后，运行默认的 JUnit 测试 contextLoads()。JUnit 将测试标记为通过，但控制台日志中显然抛出了异常。
这是生成的 pom.xml：

这是测试，如果有人真的很好奇：
package tacos;
import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;
@SpringBootTest
class TacoCloudApplicationTests {
@Test
void contextLoads() {
}
}
我不明白为什么在一个全新的项目中加载上下文会存在问题。如果我需要采取任何进一步的步骤来使开箱即用的项目测试正确运行，有人可以指出我在哪里学习答案的方向吗？或者我的整体设置中是否有可能导致这个问题的东西？
在此先感谢您的帮助！
