Spring BindingResult和bean名称的普通目标对象都不能作为请求属性使用
各位专家， 我有一个抛出上述错误的控制器代码。直到昨天，它还可以正常工作，我不知道同事对此代码做了什么，今天我看到了错误： bean名称“sideForm”的BindingResult和普通目标对象都不能作为请求属性使用 你能建议我在哪里查找这种错误吗。我是否在POST或GET方法声明中出错或返回了错误的内容 非常感谢您的帮助：）Spring BindingResult和bean名称的普通目标对象都不能作为请求属性使用,spring,spring-mvc,Spring,Spring Mvc,各位专家， 我有一个抛出上述错误的控制器代码。直到昨天，它还可以正常工作，我不知道同事对此代码做了什么，今天我看到了错误： bean名称“sideForm”的BindingResult和普通目标对象都不能作为请求属性使用 你能建议我在哪里查找这种错误吗。我是否在POST或GET方法声明中出错或返回了错误的内容 非常感谢您的帮助：） package com.att.analytics.ui； 导入java.util.array； 导入java.util.Collection； 导入java.uti
