tomcat - Spring 引导项目因 NoSuchMethodError : javax. servlet.ServletContext.getVirtualServerName()Ljava/lang/String 失败

Question

我有一个简单的 Spring Boot 项目，我已经在下面显示了 pom 文件

</project>

项目运行良好，但是当我在 eclipse 中运行这个 Spring boot 项目时，突然出现异常

我看过这个问题Getting NoSuchMethodError:javax.servlet.ServletContext.getVirtualServerName()

并尝试了解决方案中提到的大部分选项，但没有任何效果。最初我认为这可能是 servlet-api 问题，所以切换到 jetty，但随后 addServlet 开始出现另一个异常，但现在切换回 Tomcat。

Answer 1

对我来说，我能够通过删除另一个似乎仍然在我的 pom.xml 中的 servlet-api 依赖项来解决这个问题。它与我使用的另一个库引用的 servlet-api 冲突。

因此对于遇到此问题的其他人:尝试从 pom.xml 中删除 servlet-api 依赖项。
