【中文标题】jooq无法在游戏中生成类 - scala

【英文标题】：jooq unable to generate classes in play - scala

【问题描述】：

我在 scala play 框架应用程序中使用 jooq，我已从 mariadb 更改为 postgre 9.5.3，我正在尝试为 jooq 生成模型类，但在生成过程中收到错误消息。

在我的生成器设置中我的设置​​与application.conf中的设置相同，奇怪的是应用程序正常启动并且成功创建了hikari连接池，但是jooq生成器说无法访问架构。

来自游戏控制台的日志显示连接正常：

[info] 2017-02-27 22:12:27,501 play.api.Play - Application started (Dev)

applicatoin.conf 数据库设置：

  default.driver = org.postgresql.Driver
  default.url = "jdbc:postgresql://localhost:5432/footballgladiator"
  default.username = postgres
  default.password = admin
  default.maximumPoolSize=9

jook 生成器文件：

生成器错误：

【参考方案1】：

啊，我发现了，inputSchema 被命名为 public 而不是 footbalgladiator 这是我的数据库，postgres 有一个名为 public 的模式，你有你的数据库，所以生成器设置应该是

 <database>
        <name>org.jooq.util.postgres.PostgresDatabase</name>
        <inputSchema>public</inputSchema>
        <includes>.*</includes>
        <excludes></excludes>
    </database>

【讨论】：

对于 mysql 用户，inputSchema 将是 INFORMATION_SCHEMA
