java - 从包含 WAR 文件的 EAR 文件中读取属性

Question

我的属性文件有一个小问题。我使用 maven 生成一个 dependency-tree.txt 文件并将其存储在我的 EAR 文件中

EAR
  /META-INF
     dependency-tree.txt
  /lib
     some libs
  restservice.war

现在我想使用 REST 服务显示 dependency-tree.txt 文件。我在restservice.war中开发了REST端点。

我可以访问存储在 war 文件外部但ear 文件内的 dependency-tree.txt 文件吗？

这个 REST 端点的原因是，我们想为测试团队提供一个接口(interface)。通过这种方法，我们可以描述部署的 Artifact ，而无需任何手动步骤。

或者有人可以为我提供更好的解决方案吗？

谢谢

The idea is to run the plugin maven-dependency-plugin:tree at validate phase (1 phase in maven Lifecycle ) , and copy the file (tree.txt) to the right place for your WAR that after the generation of the war / ear, the file must be in the right place to be deploy a REST service.
