OpenCms 如何读取图片文件字节流
OpenCms 如何在模版里面读取图片文件字节流呢？可以参考我下面这段代码：
首先是.xsd文件：
<?xml version="1.0" encoding="UTF-8"?><xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"> <xsd:include schemaLocation="opencms://opencms-xmlcontent.xsd"/> <xsd:element name="TestNewss" type="OpenCmsTestNewss"/> <xsd:complexType name="OpenCmsTestNewss"> <xsd:sequence> <xsd:element name="TestNews" type="OpenCmsTestNews" minOccurs="0" maxOccurs="unbounded"/> </xsd:sequence> </xsd:complexType> <xsd:complexType name="OpenCmsTestNews"> <xsd:sequence> <xsd:element name="Title" type="OpenCmsString" /> <xsd:element name="Date" type="OpenCmsDateTime" /> <xsd:element name="Text" type="OpenCmsHtml" /> <xsd:element name="Image" type="OpenCmsVfsFile" minOccurs="1" maxOccurs="3"/><xsd:element name="Wap" type="OpenCmsBoolean"/> </xsd:sequence> <xsd:attribute name="language" type="OpenCmsLocale" use="required"/> </xsd:complexType> <xsd:annotation> <xsd:appinfo> <resourcebundle name="org.opencms.testnews.workplace"/> <preview uri="${previewtempfile}" /><!-- 验证开始，验证标题（Title）不能为空 --> <validationrules> <rule element="Title" regex="^.*$"message="${key.editor.errormessage.TestNews.mustnotempty}"/> <!-- 验证结束 --> </validationrules> <mappings> <mapping element="Title" mapto="property:Title" /> </mappings> <defaults> <default element="Date" value="${currenttime}"/> </defaults> </xsd:appinfo> </xsd:annotation></xsd:schema> 可以看到image不止一个，所以就要使用cms:contentloop和cms：contentshow来获得所有图片的地址。
<cms:contentload collector="singleFile" param="%(opencms.uri)" editable="true"><!-- 循环获得所有图片的src --><cms:contentloop element="Image"><c:set var="imgSrc"><cms:contentshow /></c:set> <% String imgSrc = pageContext.getAttribute("imgSrc").toString(); imageArr.add(imgSrc); %> </cms:contentloop><%CmsJspActionElement cms = new CmsJspActionElement( pageContext, request, response );CmsObject cmso = cms.getCmsObject();//获得第一张图片的字节数组CmsFile file = ( CmsFile )cmso.readFile( imageArr.get(0).toString() );byte[] buf2 = file.getContents();%> 关键是: CmsFile file = ( CmsFile )cmso.readFile( imageArr.get(0).toString() ); 这一句。
