JSP 不显示验证错误

Question

<spring:bind path="aDepartment">
                <div class="form-group ${status.error ? 'has-error' : ''}">
                    <label class="col-lg-4 control-label">Department  *</label>
                    <div class="col-lg-8">
                    <form:input class="form-control" path="aDepartment" required="true"
                        placeholder="Department" />
                    <form:errors path="aDepartment" class="control-label" />
                    </div>
                </div>
</spring:bind>

PATH是当前页面的路径。当我（故意）违反验证规则时，错误不会绑定到模型并且 jsp 不会显示错误。我应该手动将错误绑定到模型吗？如果可以，我该怎么做？

@RequestMapping(value = "/admin/adepartement/add", method = RequestMethod.POST)
    public String add(
            @ModelAttribute(value = "addadepartment") @Valid ADepartment pADepartment,
            final BindingResult pBindingResult, final ModelMap pModel) {
        if (!pBindingResult.hasErrors()) {
            ///
            }
        }else{
            return PATH;
        }
    }

Answer 1

它应该工作得很好！确保路径中的 "aDepartment" 指的是 "ADepartment" Class.

中名为 "aDepartment" 的属性
