如何在spring boot中创建单个可执行war

Question

我们正在使用spring Boot进行spring云项目。我们的目标是创建一个可以使用java-jar运行的可执行war。

有没有办法只生成可执行的WAR？

为了便于参考，我附加了pom.xml

<artifactId>discovery-service</artifactId>
<version>1.0.0-SNAPSHOT</version>
<packaging>war</packaging>

Answer 1

感谢Stephane建议删除分类器并建议使用starter.io。

我最初的问题是在目标中得到两个war文件:1)root.war和另一个2)discovery-service-boot.war

我想，魔鬼是在maven-war-plugin配置中。删除warName和outputDirectory的xml标记后，我将获得可执行的war。

我发布最后的pom.xml是为了让其他面临类似情况的人受益：
