我正在使用 Java EE 开发一个 Web 项目，它在我的计算机上运行顺畅，但是当我导出到战争并将其上传到服务器时，我收到以下错误：

在我的计算机中，它可以正常工作，稳定的内存使用量约为 450,000Kb - 服务器中 jvm 允许的内存为 512Mb，服务器是否有问题或可能是我的代码中的问题？因为我只能看到对 glassfish 和 sun 库的引用。

当您收到 OutOfMemoryError 时，堆栈跟踪根本不相关。堆栈跟踪中的代码只需要分配额外的内存，但内存可以被其他地方创建的对象消耗。

调查哪些对象消耗了内存，例如使用分析器、VisualGC 或分析堆转储。特别是，寻找在您的应用程序中定义的类，这些类在内存中具有异常多的实例。

另外，想想这两个环境之间可能有什么不同。应用程序在部署期间是否可能从数据库中读取数据，并且数据库中的数据不同？

本地计算机上 450MB 的使用量非常接近 512MB 的限制 - 由于服务器配置不同，服务器可能比本地服务器消耗更多内存。在尝试部署应用程序之前，比较服务器和本地服务器消耗的内存量。
