Web Figure的用法：Matlab官方教程

Implement a WebFigure

This example implements a WebFigure. It deploys the WebFigure service and the page that has the WebFigure embedded in it on a single server. This configuration   allows you to quickly reference your WebFigure from a JSP page with minimal configuration.

此示例实现WebFigure。 它在单个 服务器  上部署WebFigure服务和嵌入了WebFigure的页面。 此配置允许您使用最少的配置从JSP页面快速引用WebFigure。

1. Configure the web server.

• Install the MATLAB® Runtime in a location where it is accessible to the web server.
• Add matlabroot\toolbox\javabuilder\jar\javabuilder.jar to the classpath of the web server.

警告此文件使用本机资源。 至关重要的是，它只存在于Web服务器的classPATH中一次。 将此文件嵌入 Web应用 程序会导致错误。

     2. Verify that your web server is properly configured by deploying the WebFigureQuickStart application.

通过 部署  WebFigureQuickStart应用程序验证是否正确配置了Web服务器

• Deploy matlabroot\toolbox\javabuilder\jar\WebFigureQuickStart.war to your web server.
• Open http://hostName:portNumber/WebFigureQuickStart/WebFigureExample.jsp in a web browser.

The following default figure page appears:

• c.Click and drag to manipulate the figure.

For example, to zoom in the figure, click the magnifying glass icon, then hover over the figure.

例如，要放大图形，请单击放大镜图标，然后将鼠标悬停在图形上方。

验证Web服务器配置正确后，即可取消部署默认WebFigure。

    3.   Compile the getPlot function as a Java® package.

function df = getPlot()  f = figure('Visible','off');  x = -2:0.25:2;  [X,Y] = meshgrid(x);  Z = X.*exp(-X.^2-Y.^2);  contour3(X,Y,Z,30);  df = webfigure(f);  close(f);end

    4.   Create a web application containing the jar file generated by MATLAB Compiler SDK™ and a JSP file to display   the figure.

The generated jar file should be placed in the WEB-INF\lib folder of the web application. The JSP file should be in the root folder of the web application.

   5.  Open the WEB-INF\web.xml file and add the reference to WebFigureServlet.

<servlet>  <servlet-name>WebFigures</servlet-name>  <servlet-class>		com.mathworks.toolbox.javabuilder.webfigures.WebFiguresServlet	</servlet-class></servlet><servlet-mapping>    <servlet-name>WebFigures</servlet-name>    <url-pattern>/WebFigures/*</url-pattern></servlet-mapping>

     6. Copy MATLABROOT/toolbox/javabuilder/webfigures/webfigures.tld, the WebFigures customer tag handler file, to the WEB-INF folder of your web application.

    7. In the JSP file, add a reference to the WebFigure tag by including the following line of code at the beginning of the file.

<%@ taglib prefix="wf" uri="http://www.mathworks.com/builderja/webfigures.tld" %>

    8. In the JSP file, add a reference to the package you created using MATLAB Compiler SDK.

<%@ page import="getPlot.Class1" %>

    9. In the JSP file, add references to the MATLAB Compiler SDK packages that implement WebFigures.

<%@ page import="com.mathworks.toolbox.javabuilder.webfigures.WebFigure" %><%@ page import="com.mathworks.toolbox.javabuilder.*" %>

    10. In the JSP file, add code to instantiate the deployed class.

<%! Class1 myDeployedComponent; %><%!      public void jspInit()   {          try {    	    //Instantiate the Deployed Component            myDeployedComponent = new Class1();       } catch (Exception e)       {          e.printStackTrace();       }   }%><%!   public void jspDestroy()   {        if (myDeployedComponent!=null)        {            myDeployedComponent.dispose();        }        myDeployedComponent = null;   }%>

  11. Return the WebFigure and attach it to tag for display.

<%    if (myDeployedComponent!=null)    {        try        {          // Get the WebFigure from your function's output   	      WebFigure webFigure = (WebFigure)          ((MWJavaObjectRef)myDeployedComponent.getPlot(1)[0]).get();          // set it to the tag            request.getSession().setAttribute("MyFigure", webFigure);        } catch(ClassCastException e)        {            throw new Exception("Issue casting deployed components outputs to WebFigure",                                e);        } catch (Exception e)        {    	    e.printStackTrace();        }   } else {        out.println("no go");   }%><wf:web-figure name="MyFigure" scope="session"/>

  12. Run your application.

Your custom WebFigure appears:
