Spring Boot 2.2 activemq 码头冲突

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)'

该方法的类 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，它引入了自己的码头所有版本 9.4.19 依赖项，这与 spring-boot 2.2 码头 (9.4.20) 冲突

我的 pom.xml 的一部分是：

        The one we used had an Apache implementation, so going with that.

知道我该如何解决这个问题吗？

Answer 1

ActiveMQ 在这里是错误的。

jetty-all不打算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。

它没有也不可能包含 Jetty 的所有内容。

一个拥有 Jetty 生产的所有东西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 ）将已经引入您需要的正确 Jetty 传递依赖项。

您可以从命令行使用$ mvn dependency:tree来查看这一点（在排除jetty-all之前和之后）

您可能希望运行其中一个重复类查找器 maven 插件，以查看您正在执行的其他重复类并对其进行更正。
