Java 运行时错误 class 文件版本错误

Question

我几乎下载了每个 JDBC 驱动程序版本以及 JAVA 的多个版本。

每次我尝试运行 SchemaSpy 时，我都会收到以下错误：

关于如何解决这个问题有什么想法吗？

Answer 1

@texnoob 我在尝试使用旧数据库类型运行 SchemaSpy 时看到了这一点。对于更高版本的 SQL 服务器，请尝试使用 -t mssql08 而不是 -t mssql。

运行带有 -dbhelp 命令行开关的 SchemaSpy 应该 return 支持类型，但它对我不起作用。另一种查找类型的方法是在允许浏览存档的应用程序（WinZip、WinRAR 等）中打开 SchemaSpy JAR 文件。打开后，您将在路径“BOOT-INF\classes\org\schemaspy\types”中找到列出的数据库类型。

如果更改数据库类型仍然不起作用，请提供您发出的命令行语句以供进一步分析。
