Hibernate GORM生成的看似随机的1=1 where子句'；什么地方关门

有问题的示例程序：

有问题的GORM代码 问题摘要 生成的SQL查询偶尔会生成一个where子句，其中包含1=1，而我希望在（？）中看到teams\u alia1\u.id

问题的详细描述 我编写了两个集成测试来说明这个问题：

请参见src/intrgeration test/groovy/ExampleITSpec.groovy 集成测试1 总是生成SQL

select count(*) as y0_ 
from user_data this_ inner join status status_ali2_ 
     on this_.status_id=status_ali2_.id 
     inner join workflow_role_teams teams5_ 
     on this_.id=teams5_.user_data_teams_id 
     inner join role teams_alia1_ 
     on teams5_.role_id=teams_alia1_.id 
where 
(((teams_alia1_.id in (?)) and (status_ali2_.is_open=?)) 
or 
(this_.owner_id=? and (status_ali2_.is_open=?))) limit ?

select count(*) as y0_ 
from user_data this_ inner join status status_ali2_ 
    on this_.status_id=status_ali2_.id 
    inner join workflow_role_teams teams5_ 
    on this_.id=teams5_.user_data_teams_id 
    inner join role teams_alia1_ 
    on teams5_.role_id=teams_alia1_.id 
where 
((1=1 and (status_ali2_.is_open=?)) 
or 
(this_.owner_id=? and (status_ali2_.is_open=?))) limit ?

集成测试2 偶尔会生成SQL

select count(*) as y0_ 
from user_data this_ inner join status status_ali2_ 
     on this_.status_id=status_ali2_.id 
     inner join workflow_role_teams teams5_ 
     on this_.id=teams5_.user_data_teams_id 
     inner join role teams_alia1_ 
     on teams5_.role_id=teams_alia1_.id 
where 
(((teams_alia1_.id in (?)) and (status_ali2_.is_open=?)) 
or 
(this_.owner_id=? and (status_ali2_.is_open=?))) limit ?

select count(*) as y0_ 
from user_data this_ inner join status status_ali2_ 
    on this_.status_id=status_ali2_.id 
    inner join workflow_role_teams teams5_ 
    on this_.id=teams5_.user_data_teams_id 
    inner join role teams_alia1_ 
    on teams5_.role_id=teams_alia1_.id 
where 
((1=1 and (status_ali2_.is_open=?)) 
or 
(this_.owner_id=? and (status_ali2_.is_open=?))) limit ?

1=1从何而来？

示例服务

def getMyOrMyTeamsData(User me) {
    // To fix the test Toggle these two lines
    def user = me
//        def user = User.get(me.id)

    def query = UserData.where {
        (
                teams { id in me.getAuthorities().id } && status { isOpen == true }
        ) || (
                owner == user && status { isOpen == true }
        )
    }

    return query

}

更新1 调试应用程序时，您可以清楚地看到authorities变量在工作版本中传递给DetachedCriteria#handleJunction（Closure callable），但从服务方法调用时消失

集成测试1-具有权限属性

集成测试2-无权限属性

对我来说，测试总是失败，我不知道为什么测试2和3显示不同的行为，但在我将UserData.groovy中的

列表团队

更改为

列表团队

后，测试3通过了

在GORM文档中，映射字段的声明经常被忽略，这在本例中也适用

希望这也适用于您。

什么版本的grails？grails版本：3.2.6当您使用静态类型而不是

def

时会发生什么？似乎很有希望。在my IDE（IntelliJ）中运行时，所有测试都通过。但是，从命令行运行：grailstest app-integration-Dgrails.env=test每次在ExampleITSpec.groovy的第99行都会失败。我将更新版本推送到静态类型分支。我的更改：在IntelliJ中再次运行了它，而“有时失败”测试今天早上再次失败。我必须运行grails clean一次。所有测试都通过了。非常感谢你！
