java - 使用 jboss 工具/hibernate 配置连接到数据库时出错

Question

我正在尝试使用 jboss 工具 hibernate 代码生成来为我的 postgresql 数据库中的表生成 DAO 和 hibernate 映射。我已经设置了 hibernate 配置，但是当我尝试连接时出现此错误:

我查看了 StandardBasicTypes 的第 54 行，其中显示 public static final BooleanType BOOLEAN = BooleanType.INSTANCE; 并且我跟踪了 BooleanType 类中确实存在的字段 BooleanType.INSTANCE。

我正在使用 hibernate-core-4.1.8.Final.jar、hibernate-spatial-4.0-M1.jar，并且在我的 hibernate 配置中，“Hibernate 版本”是“4.0”。

Answer 1

检查类路径上是否没有两个 hibernate 版本
