grails - grails为mysql View 创建域类

Question

我有结合多个表列的mysql View 。我只想从此 View 中选择数据以在html页面中显示Web。无需使用GORM创建/更新/删除。如何为该 View 定义域类？

我的看法是这样的。

view name: testview
col1 int,
col2 varchat(50),
col3 date

谢谢

Answer 1

假设col1是主键:

class View {
    Integer col1
    String col2
    Date col3

    static mapping = {
        table name: "testview"
        version false
        id name: "col1", generator: "assigned"

        // These are unnecessary unless you change the name of the fields
        col1 column: "col1"
        col2 column: "col2"
        col3 column: "col3"
    }
}
