'String' 类型不支持验证“[object Object]”

Question

当我尝试使用 jHipster 重新生成模型时，出现以下错误：

The validation '[object Object]' isn't supported for the type 'String'.

对我做错了什么有什么想法吗？

我使用的jHipster版本是3.6.1。

        MetricActual{timeDimensionId} to TimeDimension
    }

}

Answer 1

首先删除所有包含的花括号。他们不应该在那里。其次将整个内容粘贴到 JDL studio 并确保它通过语法检查。它会在顶部用红色告诉你哪一行有问题（如果有的话）。

Answer 2

第一个错误是JDL开头和结尾的大括号。
第二个错误是 max(35) 个元素。您应该改为 maxlength(35)。
第三个错误是MetricTarget和MetricDimension之间以及MetricActual和MetricDimension之间的关系。这些是单向关系（ManyToOne）所以你应该写例如MetricTarget{hierarchyLeafCode} to HierarchyServiceCenter 而不是 MetricTarget{hierarchyLeafCode} to HierarchyServiceCenter{hrchyLeafCode}.
