我尝试使用控制台构建应用程序（gradle 构建），构建成功但是 运行 war 给我一个错误: 无法启动嵌入式 Tomcat。有人可以帮我吗？
我能够启动您的应用程序 运行。我为获得它所做的唯一更改 运行 是在 build.gradle 文件中注释掉几个依赖项。
在下面的依赖块中，注释掉了 3 行。我注释掉的 spring-boot-start-jpa 行只是因为我没有配置数据源。
但是，如果您只注释掉 servlet-api 和 jstl 依赖项，您的应用应该可以正常启动，对我来说确实如此。

//compile('org.springframework.boot:spring-boot-starter-data-jpa')
compile('org.springframework.boot:spring-boot-starter-security')

我也有这个错误，它只发生在 Intellij 上。最后我通过注释掉它来让它工作：
<dependency>

<scope>provided</scope>
</dependency>
我确实花了很多时间才弄明白这一点。希望这对遇到类似错误的人有所帮助。
清理 C:\Users\Lenovo\.m2\repository 然后重新导入所有 Maven 依赖项对我有用。我还删除了 pom.xml.
中的所有重写依赖项
在主引导应用程序上添加注释 class 对我有用。
@EnableAutoConfiguration
public class ExampleApplication{.......
添加注释 @EnableAutoConfiguration 解决了我的问题。但我唯一的疑问是 @SpringBootApplication 应该在内部添加 @EnableAutoconfiguration。这是根据 spring 网站 https://spring.io/guides/gs/rest-service/
不知道该相信什么...花了 8 个小时才弄明白。
至少就我而言，这是一个 Intellij 特定问题，因为 Boot-app 在 运行 Eclipse/VSCode.
时工作得很好
我开始遇到这个问题 post 新的 Intellij 更新 2020 CE。在使用提供的范围选项选择依赖项后，这显然已解决。
