推荐答案import com.acme.domain.* def sessionFactory sessionFactory = ctx.sessionFactory // this only necessary if your are working with the Grails console/shell def session = sessionFactory.currentSession def query = session.createSQLQuery("select f.* from Foo where f.id = :filter)) order by f.name"); query.addEntity(com.acme.domain.Foo.class); // this defines the result type of the query query.setInteger("filter", 88); query.list()*.name;
