java - Maven war 插件，没有从父 pom 获取依赖项

Question

我的目标是将一场 war 包含到另一场 war 中。查看我的项目结构:

+test-parent(这里是 spring 和 hibernate 框架的所有常见依赖项)-- test-core(所有常用类的集合type:jar)-- test-web(应作为单独的 webapp 运行的 webapp，取决于 test-core，类型:war)-- test-web-2 (依赖于test-web,test-core, type:war的webapp)

我使用了 maven war 插件来实现这一点。

由于我的 test-web-2 依赖于 test-web，所以我想合并 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 下没有包含父级所需的所有 spring jar 的 lib 文件夹.

我在两个项目中给了不同的包和 jsp 文件名。我什至能够根据需要看到正确的合并构建。

我怎样才能在 test-web 和 test-web-2 项目中生成这个 lib 文件夹以及来自父级的所有依赖 jar？

Answer 1

简化项目配置。将 java 源代码从 WAR 分离到 JAR。在此之后，您可以简单地将此 JAR 添加到另一个 WAR 作为依赖项。 合并 Java 代码在这种情况下不是一个好主意。

要合并来自 WAR 的资源，请使用 maven overlays .

示例解决方案

* 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:

• test-web-core.jar
• 测试核心.jar

test-web-2.war 有依赖:

• test-web-2-core.jar
• 测试核心.jar
