只需在 pom 中包含 spring-cloud-starter-eureka-server ，部署到 WAS ，启动应用程序 --> 生成异常

如果你从 pom 中移除 starter 并部署应用程序，应用程序可以多次启动和停止并正常工作。

所以我不明白为什么 eureka server starter 会破坏 logback 并给出这个异常

如果有人有兴趣试一试，请附上项目demo application。

注意：部署应用程序后，停止所有服务器并启动它，应用程序启动成功，停止它并单独启动它，它再次产生异常。

我相信它与类路径加载器冲突或类似的东西有关，但我无法理解。

任何帮助！

感谢示例项目！

当我建立你的战争时，我看到了

$ jar tvf bootcallbackdemo-0.0.1-SNAPSHOT.war|grep logback

470782 Fri Apr 08 08:50:02 MDT 2016 WEB-INF/lib/logback-core-1.1.7.jar

ThrowableProxy 在logback-classic-1.1.7.jar 中。

不幸的是，我没有 websphere，但我猜 websphere 有一个旧版本的 logback，它不包含 ThrowableProxy，并且正在使用它而不是 WEB-INF/lib 中定义的那个。有没有可以改变优先级的设置（几年前的weblogic中有）？

【讨论】：

嗨，Spencer，是的，我最后尝试将类加载器更改为父级，但仍然是同样的问题。我也跟着猜测 jar 冲突，但我在 websphere 中找不到 logback jar，我会在下周再试一次，并用结果更新你。

以上是关于Spring boot，Eureka 服务器，IBM WAS：logback 给出 NoClassDefFoundError ch.qos.logback.classic.spi.ThrowableP的主要内容，如果未能解决你的问题，请参考以下文章
