如何在 Spring Boot 中创建单个可执行战争

Question

我们正在使用 Spring Boot 开发 Spring Cloud 项目。我们的目标是创建一个可以使用 java -jar 运行的可执行战争。

我关注了一些关于 SO 的帖子，并且能够通过 1) 在 . 2) spring-boot-maven-plugin在执行阶段添加Repackage目标

现在通过这种方法，我得到了两个战争文件： 一场不可执行但可部署的战争 以及适合我要求的引导分类器的另一场战争

有没有办法只生成可执行的战争？

我附上 pom.xml 以方便参考

Failed to load Main-Class manifest attribute while running java -jar

Answer 1

感谢 Stephane 建议删除分类器并建议使用 starter.io。

我最初的问题是我在目标中获得了两个战争文件：

1. Root.war 和其他
2. discovery-service-boot.war

我猜，魔鬼在 maven-war-plugin 配置中。在我删除了 warName 和 outputDirectory 的 xml 标签后，我得到了可执行的战争。

我发布最终的 pom.xml 以帮助面临类似情况的其他人：
