在 websphere 中部署 Spring Boot 应用程序的 Guava 问题

Question

我有 Spring Boot 应用程序，当我作为 Java 应用程序运行时，它运行良好。

现在我按照以下网址中的步骤尝试部署到 websphere 中： How to deploy Spring Boot application in IBM Liberty and WAS 8.5

我注意到此链接中很少有人遇到类似问题：Exception caused by Guava library?

下面是我最新的带有番石榴依赖的依赖层次树：

我尝试了以下解决方案：

1) Updating springfox to various versions and see if it helps
2) Adding Guava 19.0 as dependency.

Answer 1

看起来您的 springfox 和 google-collections jar 不兼容。 NoSuchMethodError 意味着一个类正在调用目标类中根本不存在的方法。根据异常消息，这个类：

springfox.documentation.spring.web.ObjectMapperConfigurer

正在调用这个方法：

com.google.common.collect.Lists.reverse

在已加载的类版本中不存在该签名。

异常显示这些类来自哪些 jar（两者都在您的 WAR 的 WEB-INF/lib 中）：

来自 springfox-spring-web-2.7.0.jar 的 ObjectMapperConfigurer

来自 google-collections-1.0.jar 的列表

鉴于您的应用中有番石榴，我认为解决方案就是取出旧的 google-collections jar。
