我正在使用 Jaspersoft Studio 5.5.1 中的数据适配器向导来设置 Hibernate 连接。

该向导要求提供hibernate.cfg.xml我提供的 Hibernate 配置 ( )。我的 Hibernate 配置在其他设置中正常运行...

在向导中测试连接时，出现以下错误：

net.sf.jasperreports.engine.JRException: java.lang.ClassNotFoundException: org.hibernate.cfg.Configuration

该向导似乎缺少 Hibernate 二进制文件。我的问题是；如何正确地将这些二进制文件附加到 Jaspersoft Studio 的类路径？

编辑

可以使用“数据库 JDBC 连接”选项将 JAR 添加到类路径：

但这对于“休眠会话”选项是不可能的：

我工作了我的 pom 被添加到这一行

 <dependency>
<groupId>net.sf.jasperreports</groupId>
<artifactId>jasperreports</artifactId>
<version>5.6.0</version>
<type>jar</type>
</dependency>

Jaspersoft studio 类路径似乎位于：

Jaspersoft Studio-5.5.1.final\features\jre.win32.win32.x86_64.feature_1.7.0.u25\jre\lib\ext

当我将 Hibernate JAR 复制到上面的类路径时，我在答案中发布的异常变为：

新异常是由于缺少 SQL Server JDBC 驱动程序。所以我将此驱动程序复制到相同的类路径中。异常变为：

这次异常是由于缺少Bean Validation API造成的。所以我复制validation-api-1.1.0.Final.jar到 Jaspersoft 类路径。这最终足以连接到 Hibernate。

观察。我的休眠是 4.3.1。
