我需要将学生中的数据插入学生表，并将学生地址插入联系人表。
当我运行程序时，我会得到以下错误。
HTTP状态500-org.apache.jaster.jasper异常：org.springframework.beans.NotReadablePropertyException：无效bean类的属性"address"[com.techvision.model.Student]：bean属性"address"不可读或具有无效的getter方法：
getter的返回类型与setter的参数类型匹配吗？
由于您的地址属性嵌套在联系人中，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>
