java - 如何使用 Maven "shade"插件将 Apache CXF 应用程序打包成一个整体 JAR

标签 java maven-2 maven cxf

我正在编写一个基于控制台的 Java 应用程序，旨在由 cron 以批处理方式运行。批处理应用程序使用适用于 JAX-WS 的 Apache CXF 框架调用 SOAP Web 服务。

为了使部署更容易，并防止 CLASSPATH 问题，我想将应用程序(及其所有依赖项)捆绑到一个单一的 JAR 文件中...使用 the "shade" plugin for Maven .

当我从我的 Eclipse 工作区运行它时，我的应用程序运行良好。但是，当我尝试执行带阴影的 JAR 文件时，我会得到一个堆栈跟踪，如下所示:

事实上，如果您查看 this discussion board message ，我遇到了和这个人完全相同的问题。正如另一个人在该线程中指出的那样，我的问题可能与 Maven“阴影”插件有关。

Apache CXF 包含许多 JAR 文件依赖项，显然不止一个 JAR 依赖于它们的 META-INF 目录中的内容。 Maven“阴影”插件显然将所有这些 META-INF 目录合并为一个，并覆盖必要的文件而不是将它们合并在一起。

该讨论帖中的某个人提供了指向 this Maven POM file 的链接，表明有配置选项和转换器可用于使“阴影”插件正确合并这些 CXF 依赖项。我将这些设置插入到我自己的 POM 中，如下所示:

有没有人曾在 Maven 遮蔽 JAR 的上下文中使用过 Apache CXF，并且可以提供一些关于如何使其正常工作的指导？

最佳答案

就我而言，我只需要添加:

<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
     <resource>META-INF/cxf/bus-extensions.txt</resource>
</transformer>

如果你看一下这个带有和不带transformer标签的文件，会有很大的不同(只有一行与~50行)，特别是几行:

org.apache.cxf.binding.soap.SoapBindingFactory::true
org.apache.cxf.binding.soap.SoapTransportFactory::true

缺少我认为是导致问题的原因。

关于java - 如何使用 Maven "shade"插件将 Apache CXF 应用程序打包成一个整体 JAR，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/6831954/
