我的主要问题是我想使用 myfaces jsf 实现，因此，我必须在 glassfish-web.xml 中使用 delegate=false。这最终会首先从我的应用程序加载类，然后查看服务器库。

当我使用休眠时，javassist 的问题是与 osgi-weld 捆绑的版本 3.14.0-GA 和我在 pom.xml 中定义的 3.14.0-GA 不同。我还尝试从我的 pom.xml 中删除该条目（排除了对 javassist 的所有传递依赖项），但它不起作用。例外有点奇怪。

只需将 javassist-3.14.0-GA.jar 放在 GLASSFISH_HOME\domains\domain1\lib 中，并且不要将其包含在您的应用程序类路径中，如果您使用 maven 将依赖项标记为提供

<dependency>
     <groupId>org.javassist</groupId>
     <artifactId>javassist</artifactId>
     <version>3.14.0-GA</version>
     <scope>provided</scope>
</dependency>

以下票证描述了该问题： https ://issues.jboss.org/browse/WELD-570

Javassist 类使用上面提到的包：glassfish/modules/weld-osgi-bundle.jar

我们的初步解决方案是改变

<class-loader delegate="true" />

在我们的 glassfish-web.xml 中。

如果您使用 javassist 进行休眠，本文建议您切换到替代字节码提供程序 CGLIB： http ://www.java.net/node/705285

如果您在 JPA 上使用 Hibernate，则可以使用 Glassfish 的 Hibernate 进行切换：https ://blogs.oracle.com/GlassFishPersistence/entry/using_hibernate_as_jpa_provider
