jspx传递变量

我正在使用Spring Roo和jspx建立一个管理房地产投资组合的系统。

在我的“propertys / show.jspx”文件中,我使用Google Maps API嵌入了地图,现在我希望将属性的post / zip代码传递到地理编码方法,以显示属性的位置地图。

我对jsp(x)相对较新,但是我尝试了各种选项,例如使用邮政编码“id”值或使用$ {property.postcode} / $ {property.getPostcode()}但这些都不起作用。肯定有可能我想做的事情,我在网上搜索了几个小时,但一直在努力寻找有用的东西。

这是我的代码:

如果有人能给我任何可以提及的提示或提示,因为我认为这是一个基本问题而且我无法解决它真的很令人沮丧!

如果您查看display.tagx,您可以看到如下所示的对象值:

<spring:eval expression="object[field]" />

据推测,你应该能够使用这是你的jspx:

来访问邮政编码
<spring:eval expression="property[postcode]" />

例如:

<script type="text/javascript">
        //<![CDATA[
            var map;
            var post_code = <spring:eval expression="property[postcode]" />;
            ...
