今天在使用JSR-303 validation进行校验时出现了标题中的相关问题

po类相关代码：

    @Size(min=1,max=30,message="{items.name.length.error}")
    private String name;
    @NotNull(message="{items.createtime.isNUll}")
    private Date createtime;

springmvc.xml：

<mvc:annotation-driven validator="validator"></mvc:annotation-driven>
<!-- 校验器 -->
	<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean">
		<property name="providerClass" value="org.hibernate.validator.HibernateValidator" />
		<property name="validationMessageSource" ref="messageSource" />
	</bean>
	<bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
		<property name="basenames">
			<list>
				<value>classpath:CustomValidationMessages</value>
			</list>
		</property>
		<property name="fileEncodings" value="utf-8" />
		<property name="cacheSeconds" value="120" />
	</bean>	<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean">
		<property name="providerClass" value="org.hibernate.validator.HibernateValidator" />
		<property name="validationMessageSource" ref="messageSource" />
	</bean>
	<bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
		<property name="basenames">
			<list>
				<value>classpath:CustomValidationMessages</value>
			</list>
		</property>
		<property name="fileEncodings" value="utf-8" />
		<property name="cacheSeconds" value="120" />
	</bean>

controller.java:

@RequestMapping("/editItemsSubmit")
	public String editItemsSubmit(Model model, HttpServletRequest request, Integer id, @Validated ItemsCustom itemsCustom, BindingResult bindingResult) throws Exception {
		if (bindingResult.hasErrors()) {
			List<ObjectError> allErrors = bindingResult.getAllErrors();
			for (ObjectError objectError : allErrors) {
				System.out.println(objectError.getDefaultMessage());
			}
			model.addAttribute("allErrors", allErrors);
			model.addAttribute("items", itemsCustom);
			return "items/editItems";
		}

CustomValidationMessage.properties:

items.name.length.error=请输入1到30个字符的商品名称
items.createtime.isNULL=请输入商品的生产日期

第一个问题很明显是properties文件中的信息未正确加载导致的。经检查发现po类中非空校验的代号为items.createtime.isNUll,properties文件中为items.createtime.isNULL，二者不匹配导致了错误。

另附springmvc加载配置properties文件的几种方式以供学习http://blog.csdn.net/chinadim/article/details/40621671

第二个问题是由于编码问题导致的

经查询将springmvc.xml文件中的

<property name="fileEncodings" value="utf-8" />

更改为：

<property name="defaultEncoding" value="utf-8" />

或者利用jdk根目录bin文件夹下的native2ascii.exe文件将properties文件转为UTF-8也可解决。
