grails - grails:相同的物理表名称引用了多个逻辑表名称

Question

我对GORM映射有疑问。我得到这个错误

"Same physical table name [immunohistological_analysis] references several logical table > names: [STImmunoAnalysis], [GTImmunoAnalysis]"

我收到错误是因为我从来自两个数据源的两个pojo中映射了同一个表的名称，如下所示:

class GTImmunoAnalysis {

...

static mapping = {
        datasource 'generictracker'
        table "immunohistological_analysis"
        id generator: 'assigned', name: 'acc', column: 'acc'
        slideAcc column: "slide_acc"
        receptor column: "receptor"
        tumorReceptor column: "tumor_receptor"
        percent column: "percent"
        score column: "score"
        amplified column: "amplified"
        version false
        cache 'read-only'
    }
}

class STImmunoAnalysis { 

...

static mapping = {
        datasource 'sampletracker'
        table "immunohistological_analysis"
        id generator: 'assigned', name: 'acc', column: 'acc'
        slideAcc column: "slide_acc"
        receptor column: "receptor"
        tumorReceptor column: "tumor_receptor"
        percent column: "percent"
        score column: "score"
        amplified column: "amplified"
        version false
        cache 'read-only'
    }

}

谢谢你的帮助。

Answer 1

这是因为两个域都引用同一个表:

class GTImmunoAnalysis {    
    ...
    static mapping = {
        ...
        table "immunohistological_analysis"
        ...
    }
}

class STImmunoAnalysis {
    ...
    static mapping = { 
        ...
        table "immunohistological_analysis"
        ...
    }
}

尝试更改表名称:

class GTImmunoAnalysis {    
    ...
    static mapping = {
        ...
        table "gt_immunohistological_analysis"
        ...
    }
}

class STImmunoAnalysis {
    ...
    static mapping = { 
        ...
        table "st_immunohistological_analysis"
        ...
    }
}
