加入了@Valid注解 是為了實現JSR-303的驗證。

值得一提的是:SpringMVC为FreeMarker提供了支持。

首先要在頁面中引入:<#import "spring.ftl" as spring />,才會有對表單驗證的支援


<div class="form-group">                
    <label for="authorityDescription"><@spring.message "program.authority.description" /></label>
    <input type="text" class="form-control" id="authorityDescription" placeholder="<@spring.message "program.authority.description" />" name="description" value='${authority.description!""}' required>
    <#if authority??>  
        <@spring.bind "authority.description" />
        <@spring.showErrors "<br />" "color:red"/>
    </#if>
</div>

spring.bind 指定要校驗綁定的欄位。格式是: <@spring.bind 屬性名 />
spring.showErrors 指定顯示錯誤消息。格式是:<@spring.showErrors 分隔符號 樣式 />

編寫驗證配置文件: 在src/main/resources 目前下建立 ValidationMessages.properties , ValidationMessages_en_US.properties , ValidationMessages_zh_TW.properties 這三個檔案, 並放入

Size = Size must be between {2} and {1}.

這樣子運行起就可以了有多語言錯誤訊息的顯示了
