对grid数据进行修改时有字段不能识别错误

 

 

错误再现：

Unrecognized field "fkSiteId" (class com.whaty.bean.PeClass), not marked as ignorable; nested exception is com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "fkSiteId" (class com.whaty.bean.PeClass), not marked as ignorable (12 known properties

解决办法：

对于字符串类型对grid的dataColumn字段进行驼峰命名转换

 

 

• dataColumn：在sql类查询时，用于指定此字段在实体类中的成员名称，在集成功能中使用。

对于封装对象类型要进行对内部对象的.引用
