Question

我正在尝试将Apache Ignite设置为我项目中的二级Hibernate缓存提供程序，但我遇到了一个奇怪的异常。配置如下：

的pom.xml

加

<spring.version>4.3.0.RELEASE</spring.version>
<hibernate.version>4.3.8.Final</hibernate.version>
<ignite.version>1.6.0</ignite.version>

ignite-hibernate的版本必须与其他工件相同（在您的情况下为1.6.0）。

请注意，由于许可限制（Hibernate根据LGPL许可），Apache Central中未部署ignite-hibernate。您可以使用GridGain提供的存储库：

    <repository>
        <id>GridGain External Repository</id>
        <url>http://www.gridgainsystems.com/nexus/content/repositories/external</url>
