我有一个带有外部化Elasticsearch服务器的Spring Boot应用程序，它可以正常启动。一旦我将Selenium添加到POM中，我就会收到以下错误。任何帮助如何解决将不胜感激。

Answer 1

看起来Selenium正在推出一款旧版的netty-3.5.7.Final.jar。没有Selenium的Spring一直在使用netty-3.10.6.Final.jar。我无法用Maven解决这个问题。我使用Gradle创建了一个新项目，并复制到我的所有代码中。现在一切都有效。

Answer 2

谢谢@Joe Reymann，你救了我的一天。

我将我的弹簧靴从1.3.5升级到1.4.3并且我遇到了与你相同的问题，Selenium正在使用旧的netty.jar。

对于Maven，将netty从selenium中排除，maven将拉动spring boot的netty
