Spring boot 2.2 activemq jetty冲突

Question

我正在尝试将 Spring boot 与 jetty starter 一起升级到 2.2 版。由于码头版本冲突，我收到这些错误以下方法不存在：

'org.eclipse.jetty.websocket.server.NativeWebSocketConfiguration org.eclipse.jetty.websocket.server.NativeWebSocketServletContainerInitializer.initialize(org.eclipse.jetty.servlet.ServletContextHandler)'

方法的 class、org.eclipse.jetty.websocket.server.NativeWebSocketServletContainerInitializer 可从以下位置获得：

jar:file:/some-dir/target/p3.0.166-SNAPSHOT.war!/WEB-INF/lib/jetty-all-9.4.19.v20190610-uber.jar!/org/eclipse/jetty/websocket/server/NativeWebSocketServletContainerInitializer.class
jar:file:/some-dir/target/p3.0.166-SNAPSHOT.war!/WEB-INF/lib/websocket-server-9.4.20.v20190813.jar!/org/eclipse/jetty/websocket/server/NativeWebSocketServletContainerInitializer.class

我有 activemq 依赖项，它引入了它自己的 jetty-all 版本 9.4.19 依赖项，这与 spring-boot 2.2 jetty (9.4.20)

冲突

而我的部分 pom.xml 是：

知道如何解决这个问题吗？

Answer 1

这里ActiveMQ是错误的

jetty-all 不能用作项目中的依赖项。

见https://www.eclipse.org/lists/jetty-users/msg06030.html

它仅作为文档的命令行工具存在，用于向人们介绍 Jetty 的基本功能集。

它没有也不能包含所有 Jetty。

Jetty 生产的一切的单一工件是不可能的。

正如@Shilan 指出的那样，排除 jetty-all 是正确的解决方案。

使用其他适当的依赖项（似乎是 spring-boot-starter-jetty）将引入您需要的正确的 Jetty 传递依赖项。

你可以在命令行中使用$ mvn dependency:tree来查看这个（排除jetty-all之前和之后）

您可能想要运行重复的 class finder maven 插件之一，以查看您正在进行的其他重复 classes 并纠正那些。
