我需要将学生数据插入学生表和学生地址联系表。

当我运行程序时，我收到以下错误。

HTTP状态500 - org.apache.jasper.JasperException： org.springframework.beans.NotReadablePropertyException：无效 bean类的属性'address'[com.techvision.model.Student]：Bean 属性“地址”不可读或具有无效的getter方法：

getter的返回类型是否与setter的参数类型匹配？

1 个答案:

答案 0 :(得分：0)

由于您的地址属性与联系人嵌套，因此您的路径信息应如下所示。

<td><form:label path="contact.address">Contact</form:label></td>
<td><form:input path="contact.address" /></td>
