hibernate - Grails单元测试失败:此实现GORM当前不支持基于字符串的查询，例如[executeQuery]

Question

SO上还有其他问题，但是它们已经很老了，没有一个可以解决我的问题。

我从单元测试中收到以下错误:

java.lang.UnsupportedOperationException: String-based queries like [executeQuery] are currently not supported in this implementation of GORM. Use criteria instead.

打破测试的行是:

def something = SomeDomain.executeQuery("some HQL string")

当前测试如下(仅跟踪当前数据):

    @TestFor(SomeService)
    @Mock(SomeDomain)
    class SomeServiceSpec extends Specification {

        def setup() {
        }

        def cleanup() {
        }

        void "nominal getSomeThing"() {
            setup:
            def args = ['thingId':1l]

            when:
            def something = service.getSomething(args)

            then:
            println "Thing: ${something}"
        }
    }

我的设置:

Grails 3.1.12
Hibernate 4 (I upgraded to 5 with no change in behavior)
Java 1.8
Groovy 2.4.7

尝试使用HibernateTestMixin。它在Hibernate 4中支持基于字符串的HQL查询。

import grails.test.mixin.TestMixin
import grails.test.mixin.gorm.Domain
import grails.test.mixin.hibernate.HibernateTestMixin

@TestFor(SomeService)
@Domain(SomeDomain)
@TestMixin(HibernateTestMixin)
class SomeServiceSpec extends Specification {

    def setup() {
    }

    def cleanup() {
    }

    void "nominal getSomeThing"() {
        setup:
        def args = ['thingId':1l]

        when:
        def something = service.getSomething(args)

        then:
        println "THING: ${something}"
    }
}

您还需要添加到build.gradle:

dependencies {
    testCompile 'org.grails:grails-datastore-test-support'
}
