为了使用preferred-application-packages，preferred-web-inf-class必须设置为false。
WebLogic文档中的示例：
<?xml version="1.0" encoding="UTF-8"?><weblogic-web-app xmlns="http://xmlns.oracle.com/weblogic/weblogic-web-app"> <container-descriptor> <prefer-web-inf-classes>false</prefer-web-inf-classes> <prefer-application-packages> <package-name>javax.faces.*</package-name> <package-name>com.sun.faces.*</package-name> <package-name>com.bea.faces.*</package-name> </prefer-application-packages> <prefer-application-resources> <resource-name>javax.faces.*</resource-name> <resource-name>com.sun.faces.*</resource-name> <resource-name>com.bea.faces.*</resource-name> <resource-name>meta-INF/services/javax.servlet.ServletContainerInitializer</resource-name> </prefer-application-resources> </container-descriptor></weblogic-web-app>
