我试图使用"强制类型"对于使用jOOQ 3.7为我们的Oracle数据库生成类的BOOLEAN。

表格如下:

CREATE TABLE outable_name
(
  id INTEGER NOT NULL,
  -- ...
  some_boolean_field INTEGER DEFAULT 0  NOT NULL
);

使用生成Java类Gradle。相关部分如下所示:

database() {
  name('org.jooq.util.oracle.OracleDatabase')
  inputSchema(properties.getProperty('db.user'))
  includes('.*')   
  forcedTypes() {
    forcedType() {
      name('BOOLEAN')
      expression('some_boolean_field')
      types('.*')
    }
  }
}

使用info-output运行gradle-task时会抛出以下错误:

打电话&#34;姓名&#34;直接与invokeMethod

database() {
  name('org.jooq.util.oracle.OracleDatabase')
  inputSchema(properties.getProperty('db.user'))
  includes('.*')   
  forcedTypes() {
    forcedType() {
      delegate.invokeMethod('name', [
                                      'BOOLEAN'
                                    ]
      )
     expression('.*\\.is_.*|.*\\.has_.*')
     types('CHAR\\(1\\)')
    }
  }
}
