奥米特。因此，响应可能具有错误的状态代码。错误日志非常清楚，该对象在您的请求下不可用 试着在全身使用同一型号的钥匙 将方法参数从e更改为EcoleProvanceEcole
但是，如果您想使用不同的名称，请使用@modeldattribute注释。您需要指定将命令对象放入GET处理程序中的模型时使用的模型属性名称 改为 @邮戳/存档 公共字符串saveEcole@Valid@modelattributeecoleprovence， BindingResult BindingResult， 模型抛出异常{ //你的代码在这里 } 或 @邮戳/存档 公共字符串saveEcole@Valid@modeldattribute EcoleProvenance ecole， BindingResult BindingResult， 模型抛出异常{ //你的代码在这里 }
