红帽全球峰会3.7.3. 在 EAR 中启用子部署类加载器隔离
此任务演示了如何在 EAR 部署中使用特殊的部署描述符在 EAR 部署中启用子部署类加载器隔离。这不需要对应用服务器进行任何更改，也不会影响任何其他部署。
重要
即使子部署类加载器隔离已被禁用，也无法添加 WAR 部署作为依赖项。
添加部署描述符文件。
将
jboss-deployment-structure.xml部署描述符文件添加到 EAR 的META-INF目录中（如果它尚不存在），并添加以下内容：<jboss-deployment-structure> </jboss-deployment-structure>
<jboss-deployment-structure> </jboss-deployment-structure>Copy to Clipboard Copied! Toggle word wrap Toggle overflow 添加
<ear-subdeployments-isolated>元素。如果 jboss-
deployment-structure.xml 文件的内容不存在，请将 <ear文件中-subdeployments-isolated> 元素添加到 jboss-deployment-structure.xml。<ear-subdeployments-isolated>true</ear-subdeployments-isolated>
<ear-subdeployments-isolated>true</ear-subdeployments-isolated>Copy to Clipboard Copied! Toggle word wrap Toggle overflow
现在，为这个 EAR 部署启用了 Subdeployment 类装载程序隔离。这意味着，EAR 的子部署不会对每个非 WAR 子部署具有自动依赖项。
