我正在尝试在 OpenIG 上实现我自己的过滤器/处理程序版本。
我在 Eclipse 上创建了它自己的 maven 项目,编译了示例并将其打包到一个 jar 中。
我在 Jetty 8 上运行 OpenIG 2.1.0。
openig 战争部署在 $JETTY_HOME/webapps 下,而我创建的 jar 在 $JETTY_HOME/lib/ext 下。
我面临的例外是 NoClassDefFound 我的过滤器扩展的 GenericFilter 类。GenericFilter 存在于 openig 战争中,作为“内联”jar
我知道这是类加载的问题。Plugin Jar 和 OpenIG 战争不共享同一个类加载器。
我的问题是:什么形式的包装适合这种情况?
- 我可以用我的新班级重建战争 - 似乎不合逻辑,应该将战争和插件脱钩
- 我可以将插件包装为战争 - 仍然没有意义。
- 使用 OSGI - 方式过大,openIG 不是 OSGI 包
有任何想法吗 ?
