Question

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hibernate时，我遇到了javassist的问题，即与osgi-weld捆绑的版本3.14.0-GA和我在pom.xml中定义的3.14.0-GA是不同的。我还尝试从我的pom.xml中删除条目（排除所有传递依赖关系到javassist），但它不起作用。例外有点奇怪。

我该如何解决这个问题？

Answer 1

将javassist-3.14.0-GA.jar放入GLASSFISH_HOME \ domains \ domain1 \ lib并且不要将其包含在应用程序类路径中，如果你使用maven标记依赖关系提供

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

以下故障单描述了问题： https://issues.jboss.org/browse/WELD-570

Javassist Classes存在上面提到的包：的glassfish /模块/焊接OSGi的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，本文建议您切换到备用字节代码提供程序CGLIB： http://www.java.net/node/705285

如果你在JPA上使用Hibernate，你可以使用Glassfish的Hibernate进行切换：https://blogs.oracle.com/GlassFishPersistence/entry/using_hibernate_as_jpa_provider
