jakarta-ee - 有没有办法让嵌入式 EJB 容器启动得更快？

Question

我正在使用 glassfish 和 netbeans 做我的第一个 Java EE Web 应用程序。当我创建一个需要嵌入式 EJB 容器的单元测试时，它可能需要大约 30 秒才能加载。我认为这是完全可以理解的，因为它“模仿”了 glassfish 服务器。
但是后来我从 Adam Bien 那里看到了这篇文章，它说:

The entire test, with booting the container, takes on my machine about 5 seconds.

http://www.adam-bien.com/roller/abien/entry/embedding_ejb_3_1_container

所以我必须假设某些东西没有正确配置。我正在运行 Linux Mint 12，我的项目使用的是 MySQL 数据库，我的 PC 是 2Ghz 双核，4 GB 内存。大多数一切都使用 netbeans 安装中的默认设置。 (我确实订购了一个新处理器，根据 cpubenchmark.net，它将 CPU 基准测试从 1700 移动到 7800)

如何提高嵌入式 EJB 容器的启动速度？

在查看输出时，罪魁祸首似乎是:

org.hibernate.validator.engine.resolver.DefaultTraversableResolver detectJPA

这是完整的输出:

您可以尝试另一个 EJBContainer impl。

OpenEJB Embedded EJBContainer 的测试时间在 1 秒范围内。它支持 GlassFish 描述符——我们在运行 Java EE TCK 时使用它们而不是我们自己的描述符，因为我们懒得编写我们需要的数千个描述符，而 TCK 已经带有完整的 GlassFish 描述符。

或者，也许可以完全尝试不同的方法。
