Grails / GORM中的结果集映射

我想将本机SQL查询的结果映射到grails中的简单bean,类似于@SqlResultSetMapping注释所做的.

例如,给定一个查询

从//等选择x.foo,y.bar,z.baz …

将结果映射到

class FooBarBaz {
  String foo
  String bar
  String baz
}

任何人都可以提供如何在grails中执行此操作的示例吗?
提前致谢.

最佳答案 我在Grails控制台中成功测试了这个

import groovy.sql.Sql

class FooBarBaz {
  String foo
  String bar
  String baz
}

// Initialising the Sql object like this ensures that the SQL statement
// will participate in the current transaction (if one exists)          
// 'ctx' refers to the Spring ApplicationContext when using the Grails console  
def sessionFactory = ctx.getBean('sessionFactory')
Sql sql = new Sql(sessionFactory.currentSession.connection())

def query = 'select email, user_real_name, phone from user'
def results = []
sql.eachRow query, {row -> results << new FooBarBaz(foo: row.email, bar: row.user_real_name, baz: row.phone)}
