Spring 配置使用@Valid注解

依赖jar包

[group: "org.hibernate", name: "hibernate-validator", version: "${vHibernateValidator}"]
[group: "org.springframework", name: "spring-webmvc", version: "${vSpringFramework}"],
[group: "org.springframework", name: "spring-context-support", version: "${vSpringFramework}"],

Spring配置

<context:annotation-config/>

<mvc:annotation-driven/>

<!-- 以下 validator  ConversionService 在使用 mvc:annotation-driven 会 自动注册-->
<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean">
  <property name="providerClass" value="org.hibernate.validator.HibernateValidator"/>
</bean>

Java代码

@RequestMapping(value = "/xxx", method = RequestMethod.POST)
public String add(@Valid @ModelAttribute Person person, BindingResult validResult, ModelMap modelMap) {
    ...
}

需要注意的是@Valid注解后面必须紧挨着BindingResult，否则Request会匹配不上，然后报404
