BindingResult result, HttpServletRequest req)
...
一个JSP页面

<table>
<tr>
<td class="formLabels"><form:label path="firstName">
<spring:message code="label.name" />
</form:label></td>

为什么对象字段不验证为AddressForm？
Why object fields are not validated AddressForm?
请帮忙。
推荐答案
您需要装饰地址 UserAddressesForm 与 @Valid 注释。请参见 JSR 303的3.1.3节和3.5.1：Bean验证的。正如我在我的答案来解释这个问题<一href=\"http://stackoverflow.com/questions/4900077/is-there-a-standard-way-to-enable-jsr-303-bean-validation-using-annotated-method\">Is有一个标准的方式使用注释的方法以使JSR 303 Bean验证，这才是真正的使用 @Valid 注释按照JSR 303。
You need to decorate addresses member of UserAddressesForm with @Valid annotation. See section 3.1.3 and 3.5.1 of JSR 303: Bean Validation. As I explained in my answer to the question Is there a standard way to enable JSR 303 Bean Validation using annotated method, this is the real use of @Valid annotation as per JSR 303.
修改
例如：code：<一href=\"http://docs.jboss.org/hibernate/validator/4.1/reference/en-US/html/validator-usingvalidator.html#d0e410\">Hibernate Validator-对象图。 （在车内乘客的名单）
