我正在使用html，thymeleaf，Spring MVC处理应用程序，我想将表数据发送到spring控制器，但是当我点击应用程序的保存按钮时，在控制台上出错：
java.lang.IllegalStateException：既不是BindingResult也不是plain bean名称的目标对象＆＃39; salesProduct [0]＆＃39;可根据要求提供 属性
在org.springframework.web.servlet.support.BindStatus。（BindStatus.java:144）
at org.thymeleaf.spring4.util.FieldUtils.getBindStatusFromParsedExpression（FieldUtils.java:396）
浏览器错误：
HTTP状态500 - 请求处理失败;嵌套异常是 org.thymeleaf.exceptions.TemplateProcessingException：期间出错 执行处理器 ＆＃39; org.thymeleaf.spring4.processor.attr.SpringInputGeneralFieldAttrProcessor＆＃39; （销售：290）
我在控制器中添加了三个属性，如salesBean，paymentBean和salesProductFormBean，你可以在下面的spring控制器代码中看到这是html中我没有添加的原因：object =＆＃34; $ {...}＆ ＃34;在表格标签中。

我陷入了这个问题，但不知道我错过了什么。有谁知道我做错了什么？
