假设我要拥有3个Maven模块:
我想在两个模块(登录和Webapp)中都包含Java类和jsp文件。我的解决方法部分起作用,它构建了一个WAR文件,呈现了网页,看起来不错,但是当我尝试在webapp模块中使用API(登录模块的接口)时,找不到类。我认为POM文件有问题。
POM几乎相同,这是登录名和Webapp Poms之间的主要区别-Webapp依赖于登录。
来自webapp模块的POM来源:

根据您的描述,您应该考虑使用Maven覆盖。
WAR文件的覆盖图只是一个Maven项目,该项目使用另一个项目的WAR输出作为依赖项,而不是一个项目的JAR。生成覆盖项目后,基础项目的WAR文件将爆炸,并将覆盖项目中的文件添加到其中。如果覆盖项目的文件和路径与名称与基础WAR中的文件相同,则它将替换它。
您将以与现在相同的方式包含来自一个模块的战争,并覆盖当前模块中的文件(类或静态资源)。有关更多说明的博客以及逐步指南。
