我是 Spring Tools Suite 3 的新手,我正在尝试实现 XSLT 视图。到目前为止,我只进行了以下更改:

servlet-context.xml

<bean class="org.springframework.web.servlet.view.xslt.XsltViewResolver">
    <property name="prefix" value="/WEB-INF/views/" />
    <property name="suffix" value=".xsl" />
</bean>

控制器.java

@Controller
public class HomeController
{
@RequestMapping(value = "/", method = RequestMethod.GET)
public String home(HttpSession session, Model model)
{
    return "home";
}
}

我的问题是如何创建 XML 数据源并将其传递给 XSLT?我想看代码示例。

也许用你的模型返回一个 DOMSource() ,如下所示:

@RequestMapping 
public String overview(Model model) {
model.addAttribute("obj", new DOMSource());
return "list";
}

您在SpringSource 论坛上有一个示例

不要忘记 SimpleFormController(来自我链接中的示例,在 Spring 3.0.x 中已弃用,但实现 XSL 视图的逻辑是相同的。

你可以在官方文档中找到一些非常有用的东西。

特别是以下部分: 17.5.1.3 将模型数据转换为 XML 17.5.1.4。定义视图属性 17.5.1.5。文档转换

你的控制器:

package xslt;

// 为简洁起见省略了导入

public class HomePage extends AbstractXsltView {

protected Source createXsltSource(Map model, String rootName, HttpServletRequest
    request, HttpServletResponse response) throws Exception {

    Document document = DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument();
    Element root = document.createElement(rootName);

    List words = (List) model.get("wordList");
    for (Iterator it = words.iterator(); it.hasNext();) {
        String nextWord = (String) it.next();
        Element wordNode = document.createElement("word");
        Text textNode = document.createTextNode(nextWord);
        wordNode.appendChild(textNode);
        root.appendChild(wordNode);
    }
    return new DOMSource(root);
}

你的view.properties文件:

home.(class)=xslt.HomePage
home.stylesheetLocation=/WEB-INF/xsl/home.xslt
home.root=words

您的 XSLT 样式表文件:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

    <xsl:output method="html" omit-xml-declaration="yes"/>

    <xsl:template match="/">
        <html>
            <head><title>Hello!</title></head>
            <body>
                <h1>My First Words</h1>
                <xsl:apply-templates/>
            </body>
        </html>
    </xsl:template>

    <xsl:template match="word">
        <xsl:value-of select="."/><br/>
    </xsl:template>

</xsl:stylesheet>

祝你好运!

添加了关于Apache FOP 项目和使用 Servlets 进行 XSL 转换的信息:

private FopFactory fopFactory = FopFactory.newInstance();
private TransformerFactory tFactory = TransformerFactory.newInstance();

public void init() throws ServletException {
    //Optionally customize the FopFactory and TransformerFactory here
}

[..]

//Setup a buffer to obtain the content length
ByteArrayOutputStream out = new ByteArrayOutputStream();

//Setup FOP
Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, out);

//Setup Transformer
Source xsltSrc = new StreamSource(new File("foo-xml2fo.xsl"));
Transformer transformer = tFactory.newTransformer(xsltSrc);

//Make sure the XSL transformation's result is piped through to FOP
Result res = new SAXResult(fop.getDefaultHandler());

//Setup input
Source src = new StreamSource(new File("foo.xml"));

//Start the transformation and rendering process
transformer.transform(src, res);

//Prepare response
response.setContentType("application/pdf");
response.setContentLength(out.size());

//Send content to Browser
response.getOutputStream().write(out.toByteArray());
response.getOutputStream().flush();
