我有以下属性文件:
title = Welcome to Home Page
total = 5
gallery1 = images/gallery/cs.png
text1 = <b>Counter Strike</b><br />
gallery2 = images/gallery/css.png
text2 = <b>Counter Strike Source Servers Available</b>
gallery3 = images/gallery/cs.png
text3 = <b>Counter Strike</b>
gallery4 = images/gallery/cs.png
text4 = <b>Counter Strike</b>
gallery5 = images/gallery/cs.png
text5 = <b>Counter Strike</b>
我按如下方式加载:
public static HashMap<String, String> getPropertyMap(String asPropBundle) throws ApplicationException {
HashMap<String, String> loMap = new HashMap<String, String>();
ResourceBundle loRB = (ResourceBundle) moHMProp.get(asPropBundle) ;
if (loRB == null) {
throw new ApplicationException("No property bundle loaded with name: " + asPropBundle);
}
Enumeration<String> loKeyEnum = loRB.getKeys();
while (loKeyEnum.hasMoreElements()) {
String key = (String) loKeyEnum.nextElement();
loMap.put(key, loRB.getString(key));
}
return loMap ;
}
返回的地图设置为HTTP请求属性。
我在JSP中生成HTML如下:
<li class="s3sliderImage">
<img src="${map.gallery1}" />
<span>${map.text1}</span>
</li>
.
.
.
<li class="s3sliderImage">
<img src="${map.gallery2}" />
<span>${map.text2}</span>
</li>
如何在循环中动态执行此操作?我在属性文件的total
属性中有总记录数。
答案 0 :(得分:2)
资源包已经是从键到值的映射,除了它具有回退机制。为什么要将其内容复制到另一个地图?
只需使用<fmt:message>
标记:其目标正是从资源包中获取消息并将其输出到JSP编写器。它当然可以参数化:
<fmt:setBundle basename="the.base.name.of.your.Bundle"/>
<fmt:message key="text2"/>
<img src="<fmt:message key="gallery2"/>" />
<fmt:message key="greeting">
<fmt:param value="${user.firstName}"/>
</fmt:message>
最后一段显示“欢迎约翰!”的片段。如果问候键的值是“欢迎{0}!”。
标记还可以将值存储在变量中,并将EL表达式作为参数,因此该片段应该可以实现循环:
<fmt:message var="total" key="total"/>
<c:forEach begin="1" end="${total}" varStatus="loopStatus">
<li class="s3sliderImage">
<img src="<fmt:message key="gallery${loopStatus.index}"/>" />
<span><fmt:message key="text${loopStatus.index}"/></span>
</li>
</c:forEach>
