無法從命令行生成java：org.jooq.exception.DetachedException：無法執行查詢。沒有連接配置

Question

我試圖從我的數據庫生成JOOQ Java代碼。

當我執行

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) 

我不知道爲什麼它不會生成Java代碼。 的啓動表示：

      This value can be used to reverse-engineer standard jOOQ-meta XML formats

      You can also provide your own org.jooq.util.Database implementation 
      here, if your database is currently not supported -->

     <!-- All elements that are generated from your schema (A Java regular expression. 
      Use the pipe to separate several expressions) Watch out for 
      case-sensitivity. Depending on your database, this might be 
      important! 

      You can create case-insensitive regular expressions using this syntax: (?i:expr) 

      Whitespace is ignored and comments are possible. 
      --> 
     <includes>.*</includes> 

     <!-- All elements that are excluded from your schema (A Java regular expression.

      includes -->

您使用JTDS作爲驅動程序實現，但是一個SQL Server JDBC驅動程序URL：

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

的jTDS連接URL格式略有不同。從本質上講，你錯過了jtds:前綴和數據庫名稱是由前綴/：

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