Question

我正在使用GWT + GAE在我的MAC上构建应用程序。在这个应用程序中，我有DTO的，并从DTO转换为持久实体，我使用它的Mapper对象Dozer Library。一切编译和的Windows运行良好，但是当我试图在MAC我得到以下警告运行我的托管模式的应用程序：

是否有可能解决这个警告？

Answer 1

是的，禁用JMX bean的自动注册。从Dozer configuration页面，dozer.autoregister.jmx.beans默认为true。将其设置为false。现在这是通过一个属性文件完成的，我不确定你可以用GAE来做到这一点。如果你不能，你必须获得源代码的副本，禁用它并重新编译它。

这就是说，它看起来像一个警告，但我不知道如何推土机会对此作出反应，所以你只需要尝试看看。这可能是好的，但即使它是，我仍然会修复它。
