spring4采用JSR349标准校验数据

   Spring4.1内置支持了JSR349校验数据，相关配置如下

     <!-- spring validation -->
     <mvc:annotation-driven conversion-service="conversionService"  validator="validator"/>
    
        <bean id="conversionService"
          class="org.springframework.format.support.FormattingConversionServiceFactoryBean"/>
          <bean id="validator"
         class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean">
         	  <property name="providerClass"  value="org.hibernate.validator.HibernateValidator"/>
       		 <!--不设置则默认为classpath下的 ValidationMessages.properties -->
        	<property name="validationMessageSource" ref="validatemessageSource"/>
         </bean>
          <bean id="validatemessageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">  
	        <property name="basename" value="classpath:validatemessages"/>  
	        <property name="fileEncodings" value="utf-8"/>  
	        <property name="cacheSeconds" value="120"/>  
    	</bean>

      注意相关架包版本

     	<!--  javax.validation-->
		<groupId>javax.validation</groupId>
			<artifactId>validation-api</artifactId>
			<version>1.1.0.Final</version>
		</dependency>
			<!--  hibernate-validator-->	
		<dependency>
			<groupId>org.hibernate</groupId>
			<artifactId>hibernate-validator</artifactId>
			<version>5.2.2.Final</version>
			</dependency>

     controller演示

    	 @RequestMapping(value="/test", method=RequestMethod.GET) //json xml vm
	@ResponseStatus(HttpStatus.OK) //200
	 public String getUser(ModelMap  model,@Valid AccountQuery query,BindingResult bindingResult )   {
	 System.out.println(query.getUserName());
	if(bindingResult.hasErrors()){		
		for(FieldError o:bindingResult.getFieldErrors()){			
			model.put(o.getField(), o.getDefaultMessage());
		}
		model.put("error", true);
		model.remove("accountQuery");
		return "";
	}
		model.put("error", false);
		return "";

	 }
    

      model只需要在相关字段上添加注解就可以了，附件里面是JSR-349部分规范
