我是Spring MVC的新手。我想在我的网页上显示Matlab WebFigure。我使用Matlab javabuilder将我的程序部署到java类中。 Java类返回Webfigure。在我的web项目的控制器中，我想将WebFiggure html字符串添加到模型中。然后，我想它显示：matlab webfigure in spring mvc
Object[] result = transformace.transformace(4);
MWJavaObjectRef ref;
ref = (MWJavaObjectRef)result[0];
obrazek = (WebFigure)ref.get();
webFigures = new WebFigures("WebFigures",getServletContext());
String webFig = webFigures.getHtmlEmbedString(obrazek,"obrazek", "session", "", "", "");
model.addObject("webFig", webFig);
在HelloWorldPage.jsp我希望得到的数字，它dislay：* .JSP页面上引用webFig时
${webFig}
不过，我得到一个错误：
Spring MVC Hello World Example
hello world mod2
HTTP Status 404 - /spring2-mvc-xml-hello-world/WebFigures/interface
type Status report
message /spring2-mvc-xml-hello-world/WebFigures/interface
description The requested resource is not available.

你能帮我吗？

去找服务文件的春天服务器的一个例子，更改文件和完成的。这里根本就不需要谈论matlab，它不相关。 – Snickers3192
Thx置评。我编辑了这篇文章。我忘了提及我使用Matlab Javabuilder从Matlab程序创建类。 Matlab程序返回Webfigure。使用WebFigure函数getHtmlEmbedString我应该得到一个字符串，它将以某种方式在网页上显示为Matlab图形。然而，当我将它添加到模型然后从* .jsp页面调用它来显示它时，这不起作用...你知道它为什么不起作用吗？ Thx很多 –
就像我说的去找个地方的例子。看起来你从mkyong找到一个...所以我没有看到你在寻找另一个问题。我的建议是使用SpringBoot找到一个，Spring中的XML已经死了。您可以使用@ResponseBody返回一个字符串HTML。仍然在谈论Matlab，请在发布问题时专注于您的问题。这不仅仅是我在做什么使它工作。如果你这样做的可能性很大，你会在右侧看到与你寻求的答案相关的问题。否则你会混淆SO。 – Snickers3192
