java - 错误MVC org.springframework.validation.BeanPropertyBindingResult : 1 errors with array

嗨，我尝试将bean中的数组从jsp传递到java。

@ModelAttribute("areasActividadAdminBean")AreasActividadAdminBean areasActividadAdminBean

Agrupacion[] listaAgrupaciones = x;

model.addAttribute("areasActividadAdminBean",areasActividadAdminBean);

在JSP中，我有这个:

<form:form commandName="areasActividadAdminBean" .....>

<form:hidden path="listaAgrupaciones"/>

<input type="submit" value="Button"/>

但是我得到这个错误:

org.springframework.validation.BindException: org.springframework.validation.BeanPropertyBindingResult: 1 errors
Field error in object 'areasActividadAdminBean' on field 'listaAgrupaciones': rejected value

最佳答案

确保BindingResult方法参数跟随您要绑定(bind)到的对象。例子

public String add(@Valid DomainObject domainObj, BindingResult result, ModelMap model) {
