java - 无法从命令行生成java : org. jooq.exception.DetachedException : Cannot execute query. 未配置连接

Question

我尝试从我的数据库生成 JOOQ Java 代码。

当我执行时

java -cp "bla.xml;jooq-3.5.0.jar;jooq-meta-3.5.0.jar;jooq-codegen-3.5.0.jar;jtds.jar" org.jooq.util.GenerationTool bla.xml

我得到:

org.jooq.exception.DetachedException: Cannot execute query. No Connection configured
        at org.jooq.impl.AbstractQuery.execute(AbstractQuery.java:303)

我不知道为什么它不生成java代码。初创公司说:

您使用 jTDS 作为驱动程序实现，但使用 SQL Server JDBC 驱动程序 URL:

jdbc:sqlserver://localhost:1433;databaseName=x

jTDS 连接 URL 格式略有不同。本质上，您缺少 jtds: 前缀，并且数据库名称以 /:

为前缀

jdbc:jtds:sqlserver://localhost:1433/x
