Grails 2.2.2 createCriteria抛出错误

我已经在互联网上搜索过了，但除了这个Im使用的Grails 2.2.2之外没有找到任何东西。这个问题影响1.7.10，但仍然没有

解决

问题

当我将情商（‘代码’、‘吉他’）更改为（‘代码’、[‘吉他’、‘贝司’、‘长笛’）

我得到错误信息：

org.codehaus.groovy.runtime.GStringImpl cannot be cast to java.lang.String

工作代码

//this code is working like expected 
def c = Project.createCriteria();
this.ids = c.list {
    projections {
        property 'id'
    }
    instruments{
        eq('code', 'guitar')
    }
}

//when I change the code to this one I get the error.
def c = Project.createCriteria();
this.ids = c.list {
    projections {
        property 'id'
    }
    instruments{
        //### This line create the problem!!
        'in'('code', ["guitar", "bass", "flute"])
    }
}

不工作代码

//this code is working like expected 
def c = Project.createCriteria();
this.ids = c.list {
    projections {
        property 'id'
    }
    instruments{
        eq('code', 'guitar')
    }
}

//when I change the code to this one I get the error.
def c = Project.createCriteria();
this.ids = c.list {
    projections {
        property 'id'
    }
    instruments{
        //### This line create the problem!!
        'in'('code', ["guitar", "bass", "flute"])
    }
}

任何帮助都将不胜感激

谢谢

问题似乎是您在列表中使用了双引号，请尝试以下方法：

this.ids = Project.withCriteria {

    projections {
        property 'id'
    }

    instruments{
        'in'('code', ['guitar', 'bass', 'flute'])
    }
}

是的！！！！！！！！！！！：））非常感谢。顺便说一句，数组是用params.entrySet（）.findAll{it.key.startsWith（“musicalStyles”）}动态创建的。每个{ms=“$it.value”；}

ms

是

数组

你知道如何用简单的代码更改双cote吗？这似乎是一个单独的问题，你能在这里写一篇新文章并粘贴链接吗？
