Error deploy spring-boot 2.5.x app in Websphere 8.5.5 throw java.lang.NoClassDefFoundError: javax.servlet.http.HttpSessionIdListener

Question

我在 websphere 8.5.5 上部署了一个 spring-boot 应用程序。使用 spring-boot 2.3.x 它可以正常工作，而在更新到版本 2.5.x 之后。简单的堆栈跟踪是：

Answer 1

Spring Boot 2.5 需要 Servlet 3.1 / Java EE 7.

WebSphere 8.5 是 Servlet 3.0/Java 仅限 EE 6。

您需要 WebSphere 9.0 来支持 Servlet 3.1。 / Java Spring Boot 2.5.

要求的 EE 7
