Spring 引导：java.lang.IllegalArgumentException：找到多个名为 [spring_web] 的片段
Spring Boot : java.lang.IllegalArgumentException: More than one fragment with the name [spring_web] was found
我在 tomcat 上部署 spring 启动 war 时遇到了这个问题 9.I 尝试了很多解决方案，例如清理项目和我在 Whosebug 中找到的所有可能的解决方案，但没有任何效果，其中一个在 web.xml 中提供绝对排序，但它是一个 spring 启动应用程序，所以我不需要使用 web.xml file.The 应用程序与本地主机完美配合，当我在 server.Below 上部署 war 文件时出现问题是错误。

如果有人知道这个错误，请帮助我。
最后我找到了一些解决方案，看起来有一些 spring 依赖冲突是 there.So 我所做的很简单，用另一个名字重新创建了项目，然后它开始工作并且错误也消失了。
另一种可能的解决方案是以正确的方式清理您的服务器（我没有尝试过，但我认为它会起作用）。
清理服务器（在我的例子中是 tomcat）
要么
删除 tomcat 服务器和工件 ID。重新配置就可以了
