Question

我的目标是将战争纳入另一场战争。请参阅我的项目结构：

+ test-parent（这里是spring和amp; hibernate框架的所有常见依赖项） - test-core（所有常见类的集合类型：jar） - test-web（应该作为单独的webapp运行的webapp，取决于test-core，类型：war） - test-web-2（webapp取决于测试网，测试核心，类型：战争）

我使用了maven war插件来实现这一目标。

由于我的test-web-2依赖于test-web，我想合并test-web-2中的所有类和资源。当我运行mvn install时，我的所有构建都成功了，但是当我在服务器上运行test-web或test-web-2时，它在WEB-INF下没有lib文件夹，所有必需的spring jar都来自于父。

我给了包＆amp;两个项目中的jsp文件名都不同。我甚至能够根据需要看到正确的合并构建。

如何在test-web和amp;中生成此lib文件夹？ test-web-2项目包含来自父母的所有依赖罐子？

Answer 1

简化项目配置。将java源代码从WAR分隔为JAR。在此之后，您只需将此JAR添加到另一个WAR作为依赖项。在这种情况下，合并 java代码并不是一个好主意。

用于合并来自WAR的资源使用maven overlays。

样品溶液

* test-parent.pom
  * test-core (test-core.jar)         - shared code
  * test-web-parent (test-web-parent.pom)   - first project
    * core (test-web-core.jar)
    * web (test-web.war)
  * test-web-2-parent (test-web-2-parent.pom) - second project
    * core (test-web-2-core.jar)
    * web (test-web-2.war)

test-web.war有依赖关系：

测试的web-core.jar添加
测试core.jar添加

test-web-2.war有依赖关系：

测试的web -2- core.jar添加
测试core.jar添加

Answer 2

我认为问题在于你正在尝试做一些不符合J2EE标准的事情。将war文件包含在另一个war文件中是没有意义的。

处理此类依赖关系的“标准”方法是将您的部署打包为.ear文件，将共享资源打包为耳内的jar文件，以及使用这些共享依赖项的war文件也在ear文件中。

看看maven包装插件的“耳朵”包装选项。

Maven war插件，没有从父pom获得依赖
