Spring语言环境消息仅在spring:form标记中不起作用 [英] Spring locale messages don't work only within spring:form tag

问题描述

您好，我有一个表单输入按钮，如下所示:

Hello I have a form input button as follows :

<form:input path="creationUsr.lastName" type="text" name="creationUsr.lastName" id="creationUsr.lastName" class="login-text" placeholder="<spring:message code='tile.form.lastName'/>" value=""/>

这是我的spring上下文语言环境设置:

Here is my spring context locale setting :

  <mvc:interceptors>   

                <bean id="localeChangeInterceptor" class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor"/>

        </mvc:interceptors>



        <bean id="localeResolver" class="org.springframework.web.servlet.i18n.CookieLocaleResolver">

                <property name="defaultLocale" value="en" />

        </bean>

如果我将其放在表单标签之外:

If I put this out of form tag :

<spring:message code='tile.form.lastName'/>

值是我应该的.

我有办法解决这个问题，但这有点丑陋.我可以不使用spring和常规的<input type="text" name="lastname">而不是<form:input ..恢复到常规形式，然后将表单序列化为json并使用javascript做文章.

I have a way around this but it's kind of ugly. I could revert to normal forms without using spring and regular <input type="text" name="lastname"> instead of <form:input .. and then serialize form to json and do a post with javascript.

我敢肯定，必须有一种使用Spring MVC做到这一点的方法.

I'm sure there must be a way to do this with spring mvc.

推荐答案

您不能在另一个JSP标记的属性内使用JSP标记.要执行您想要的操作，请将消息保存在page-scope属性中，然后使用EL将消息传递到输入标签:

You can't use a JSP tag inside an attribute of another JSP tag. To do what you want, save the message in a page-scope attribute, and use the EL to pass the message to the input tag:

<spring:message code='tile.form.lastName' var="lastNameMessage"/>
<form:input path="creationUsr.lastName" 
            type="text" 
            name="creationUsr.lastName" 
            id="creationUsr.lastName" 
            class="login-text" 
            placeholder="${lastNameMessage}" 
            value=""/>
