java - JDK 11 Spring Boot 2 .TypeNotPresentException : Type javax. servlet.Filter 不存在

Question

我有以下 pom.xml，其中包含手动 jax deps jaxb-api、jaxb-impl 和 jaxb-core 由于其从 JDK 11 中删除:

在mvn clean:install之后，但是当尝试运行应用程序时，我不断收到有关过滤器的错误。

添加 3 个额外的依赖项后还有什么问题吗？

Answer 1

spring-security-oauth2 项目目前对 Spring MVC 和 Servlet API 具有很强的依赖性。请引用WebFlux oauth2 doc
