Grails指南摘要-303-自定义对象映射

domain对象如下

class Person {
    String frstName
    String lastName
    Integer age
}

属性和字段对应定义

class Person {
    String frstName
    String lastName
    Integer age
    static mapping = {
        id column:'person_id'
        frstName column:'person_frst_name'
        lastName column:'person_last_name'
        age column:'person_age'
        version false
    }
}

domain和表名对应定义

class Person {
    String frstName
    String lastName
    Integer age
    static mapping = {
          table 'people'
    }
}
