Question

我正在开发一个项目，我有两个模块，一个是处理客户端操作的Web模块和一个将进行其他处理的java模块，还将使用Web模块创建的war来初始化嵌入式jetty 。我正在使用Intellij进行开发。

以下是模块信息：

WebServiceViewer
       |
       --> CoreService - java module
       --> ClientDashboard - web module ( doesn't have pom as created as web project)

我在ClientDashboard上添加了CoreService的依赖项。但是当我打印classpath时，我没有在classpath中看到war文件。

这是我的pom.xml文件。 Web Project pom.xml：

<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            </plugin>

        </plugins>
    </build>
</project>

这是我用来打印类路径的java类，我将使用它来用web war启动jetty。 EntryMain.java 公共类EntryMain {

public static void main(String[] args) {
    EntryMain entryPoint = new EntryMain();
    ClassLoader cl = ClassLoader.getSystemClassLoader();

    URL[] urls = ((URLClassLoader)cl).getURLs();

    for(URL url: urls){
        System.out.println(url.getFile());
    }
}

}

以下是我的类路径的输出：

如何将生成的战争带到类路径？

Answer 1

WAR文件永远不会放在类路径中。

您需要了解如何使用嵌入式Jetty 部署 WAR文件。

作为此过程的一部分，Jetty将使用SystemClassLoader创建一个新的隔离类加载器，您将其作为父级（或祖父母或其他任何东西，具体取决于Jetty的工作方式）。在委托给父类之前，这个类加载器首先会查找类。
