mysql - 数据截断 : Truncated incorrect DOUBLE value: '3ML80909540'

Question

我有一个遗留数据库，相应的领域类是

class Assets{
    String id
    AssetsFinancial assetsFinancial = new AssetsFinancial()
    static constraints = {
        assetsFinancial(nullable: true)
    }
    static mapping = {
        version false
        id generator: "assigned", column: '`id`'
        assetsFinancial column: '`id`', insertable: false, updateable: false
    }
}

和

class AssetsFinancial{
    Integer appraisal
    Boolean doubleTerVar
    static mapping = {
        version false
        id generator: "assigned"
    }
    static constraints = {
        appraisal nullable: true
        doubleTerVar nullable: true
    }
}

当我更新 AssetsFinancial 实例的属性时，例如 assetsFinancialInstance.appraisal=2222 并且 hibernate 尝试“提交”它给我的更改

我花了很多时间来查找原因，但无法找出原因，任何线索都会对我有所帮助。如果需要更多信息，请询问。

更新: hibernate 日志

2014-12-26 14:51:35,099 [http-bio-8080-exec-3] DEBUG hibernate.SQL  - update assets_financial set appraisal=?,  double_ter_var=? where id=?
2014-12-26 14:51:35,100 [http-bio-8080-exec-3] TRACE sql.BasicBinder  - binding parameter [1] as [INTEGER] - [1003]
2014-12-26 14:51:35,100 [http-bio-8080-exec-3] TRACE sql.BasicBinder  - binding parameter [2] as [BOOLEAN] - [false]

Answer 1

终于找到了罪魁祸首

从SQL日志中我们可以看出2014-12-26 14:51:35,101 [http-bio-8080-exec-3] TRACE sql.BasicBinder - 绑定(bind)参数 [3] 为 [BIGINT] - [1298944] 这里的数据类型是BIGINT 但它应该是 VARCHAR 然后我在我的 AssetsFinancial

中添加 String id

class AssetsFinancial{
String id
//rest of code
}

现在一切都很好:)
