今天在使用JSR-303 validation進行校驗時出現(xiàn)了標(biāo)題中的相關(guān)問題

po類相關(guān)代碼：

    @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>
<!-- 校驗器 -->
    <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=請輸入1到30個字符的商品名稱
items.createtime.isNULL=請輸入商品的生產(chǎn)日期

第一個問題很明顯是properties文件中的信息未正確加載導(dǎo)致的。經(jīng)檢查發(fā)現(xiàn)po類中非空校驗的代號為items.createtime.isNUll,properties文件中為items.createtime.isNULL，二者不匹配導(dǎo)致了錯誤。

另附springmvc加載配置properties文件的幾種方式以供學(xué)習(xí)http://blog.csdn.net/chinadim/article/details/40621671

第二個問題是由于編碼問題導(dǎo)致的

經(jīng)查詢將springmvc.xml文件中的

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

更改為：

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

或者利用jdk根目錄bin文件夾下的native2ascii.exe文件將properties文件轉(zhuǎn)為UTF-8也可解決。
