【问题描述】：

我已将 Wildfly 10 中的 Jaybird 依赖项从 Jaybird 2.2.11 升级到 Jaybird 3.0.0-alpha-1。当我尝试创建连接时，现在出现以下异常。

启动后的第一次连接（在管理控制台中测试时）：

随后尝试测试连接：

我将以下 module.xml 用于 Jaybird 驱动程序：

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.0" name="org.firebirdsql">
  <resources>
    <resource-root path="jaybird-3.0.0-alpha-1.jar"/>
  </resources>
  <dependencies>
    <module name="javax.api"/>
    <module name="javax.transaction.api"/>
    <module name="javax.resource.api"/>
  </dependencies>
</module>

这是什么原因造成的，我该如何解决？

注意：这个问题/答案来自错误报告JDBC-449

【参考方案1】：

在提问时，Jaybird 3 的测试版本还依赖于 javax.xml.bind 中的类，如 java.lang.ClassNotFoundException: javax.xml.bind.JAXBException 所示。此异常会导致编码定义的加载失败，进而导致org.firebirdsql.encodings.EncodingFactory$DefaultEncodingFactory 的加载失败。结果，无法建立连接。

后续尝试的异常是因为无法加载EncodingFactory$DefaultEncodingFactory。

注意：对 javax.xml.bind 的依赖已在 Jaybird 3.0.0 最终版本中删除，因此对于 Jaybird 的最终版本不需要以下解决方法3 及更高版本（请参阅下面有关 Jaybird 3.0.4 及更高版本的说明）。

解决方案是将 javax.xml.bind.api 的依赖添加到 Jaybird 模块的依赖中：

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.0" name="org.firebirdsql">
  <resources>
    <resource-root path="jaybird-3.0.0-alpha-1.jar"/>
  </resources>
  <dependencies>
    <module name="javax.api"/>
    <module name="javax.transaction.api"/>
    <module name="javax.resource.api"/>
    <module name="javax.xml.bind.api"/> <!-- Add this -->
  </dependencies>
</module>

Jaybird 3.0.4 及更高版本的注意事项

Jaybird 3.0.4 for Java 7 只重新引入了对 JAXB 的依赖。如果可能，切换到 Java 8 版本的 Jaybird，否则应用此解决方案。
