工作的需要，用到了在jsp中调用xml、xslt生成静态页面，下面把自己写过的放到这，以后备用和学习。。。写的不好，尽管扔砖头。。。
第一种实现方式：：
xml从调用服务器端的方法返回字符串类型
<%@page language="java" import="java.util.*" pageEncoding="GB18030"%>
<%@page import="java.io.FileInputStream"%>
<%@page import="java.io.File"%>
<%@page import="org.springframework.web.context.support.WebApplicationContextUtils"%>
<%@page import="org.springframework.context.ApplicationContext"%>
<%@page import="java.io.ByteArrayOutputStream"%>
<%@page import="javax.xml.transform.TransformerFactory"%>
<%@page import="javax.xml.transform.stream.StreamResult"%>
<%@page import="javax.xml.transform.stream.StreamSource"%>
<%@page import="javax.xml.transform.Transformer"%>
<%@page import="服务器端bean"%>
<%@page import="java.io.StringReader"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path + "/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>XXX界面</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
</head>
<body>
<%
String topicName="";
if(request.getParameter("topic")!=null){topicName = request.getParameter("topic");}
ApplicationContext applicationContext = WebApplicationContextUtils.getWebApplicationContext(this.getServletContext());
//下面这句是加载服务器端bean
XXXService xxxService = (XXXService) applicationContext.getBean("xxxService");
//以下是调用服务器端方法发挥xml格式字符串
String xmlSource = xxxService.loadTopicDefineXmlByCn(topicName);
StreamSource xml = new StreamSource(new StringReader(xmlSource));
StreamSource xsl = new StreamSource(new File("d:\\Tomcat-6\\webapps\\项目\\info\\model.xslt"));
ByteArrayOutputStream resultByte = new ByteArrayOutputStream();
//response.setContentType("text/html; charset=UTF-8");
StreamResult result = new StreamResult(resultByte);
Transformer trans = TransformerFactory.newInstance().newTransformer(xsl);
trans.setParameter("entity_name",topicName);
//trans.setOutputProperty("encoding","UTF-8");
trans.setOutputProperty(javax.xml.transform.OutputKeys.ENCODING,
"GB2312");
trans.transform(xml, result);
out.print(resultByte.toString());
%>
</body>
</html>
第二种实现方法：：
--------xml文件以路径的方式获得
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>界面</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
</head>
<body>
<%
String topicName="";
if(request.getParameter("topic")!=null){topicName = request.getParameter("topic");}
ApplicationContext applicationContext = WebApplicationContextUtils.getWebApplicationContext(this.getServletContext());
//下面这句是加载服务器端bean
XXXService xxxService = (XXXService) applicationContext.getBean("xxxService");
FileInputStream sourceXml = new FileInputStream(resourceService.loadTopicDefineXmlByCn(topicName));
//FileInputStream sourceXml = new FileInputStream(new File("D:\\Tomcat-6\\webapps\\项目\\info\\model.xml"));
ByteArrayOutputStream resultByte = new ByteArrayOutputStream();
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer(new StreamSource(new File("d:\\Tomcat-6\\webapps\\项目\\info\\model.xslt")));
transformer.setParameter("entity_name",topicName);
StreamResult streamResult = new StreamResult(resultByte);
transformer.setOutputProperty(javax.xml.transform.OutputKeys.ENCODING,
"GB2312");
transformer.transform(new StreamSource(sourceXml), streamResult);
out.print(resultByte.toString());
%>
</body>
</html>
