我的索引文件就像底层:
<html>
<head>
<title>App Store For Publish, Download Android Apps</title>
<meta name="layout" content="main" />
<parameter name="sideBarSetting" value="main"/>
</head>
<body>
<g:if test="${flash.message}">
<div class="message">${flash.message}</div>
</g:if>
<g:announcements/>
<g:include controller="cache" action="showFeatured"/>
<g:include controller="cache" action="latestProducts"/>
<div class="push"></div>
<g:include controller="cache" action="mostPopular"/>
<div class="push"></div>
<g:include controller="cache" action="allCategories"/>
</body>
它适用于 Grails 1.0、1.2.2 和现在的 1.3.7。
在您尝试包含的每个操作中,您不能渲染视图,而是渲染模板。模板文件只能包含 HTML 片段,不能包含头部、布局元数据等。
在我的缓存控制器中
def latestProducts = {
cache shared:true, validFor: 300
def htmlCacheManager = HtmlCacheManager.getInstance()
def key = 'latestProducts'
def content = htmlCacheManager.getHtmlContent(key)
if (!content) {
def products = productService.get5LatestProducts(params)
if (products){
content = g.render(template:'/common/product/productLatestListTemplate', model:['productInstanceList' : products, 'type':'latest'])
htmlCacheManager.store(key, content, Boolean.TRUE)
} else {
log.debug('No latest product found')
}
}
render content ?: ''
}
模板文件:
<div class="list">
<fieldset>
<legend><g:message code="product.latest"/> <g:link action="feed" controller="product" params="['type':type]" target="_blank"><img src="${resource(dir:'images', file:'feed-icon.gif')}" height='16' width='16' alt="Feeds"/></g:link></legend>
<g:each in="${productInstanceList}" var="product">
<div class="product">
<g:render template="/common/product/productSingleListTemplate" model="['product':product]" />
</div>
</g:each>
</fieldset>
</div>
