java<cms:include不带<p>标记

Question

有没有类似<cms:include type="OpenCmsString" element="text1" />的解决方案？因为我的<cms:include element="text1">的输出总是给我带有<p>标记的数据

感谢您的帮助

我曾经为此创建了自己的标签（StripPTag）。您可以编译该类并将其包装在jar文件中，然后将其部署到opencms webapp lib文件夹中

package com.opencmsserver.taglib;

import org.opencms.flex.CmsFlexController;
import org.opencms.jsp.Messages;
import org.opencms.main.CmsLog;

import javax.servlet.ServletRequest;
import javax.servlet.jsp.JspException;
import javax.servlet.jsp.tagext.BodyTagSupport;

import org.apache.commons.logging.Log;

/**
 * Removes the <p> tag from the surrounded content, 
 * because FCKEditor always add <p> tag to content at 
 * the beginning and end when using the html editor component  
 *
 * @author  Mathias Lin 
 * 
 * @version $Revision: 0.1 $ 
 * 
 * @since 0.4 
 */
public class StripPTag extends BodyTagSupport {

    /** Serial version UID required for safe serialization. */
    private static final long serialVersionUID = -2361021288258405388L;

    /** The log object for this class. */
    private static final Log LOG = CmsLog.getLog(StripPTag.class);


    /**
     * @see javax.servlet.jsp.tagext.Tag#doEndTag()
     * @return EVAL_PAGE
     * @throws JspException in case soemthing goes wrong
     */
    public int doEndTag() throws JspException {

        ServletRequest req = pageContext.getRequest();

        // This will always be true if the page is called through OpenCms 
        if (CmsFlexController.isCmsRequest(req)) {
            try {
                // Get link-string from the body and reset body 
                String content = getBodyContent().getString();
                content = content.replaceAll("<p>", "");
                content = content.replaceAll("</p>", "");
                getBodyContent().clear();
                getBodyContent().print(content);
                getBodyContent().writeOut(pageContext.getOut());

            } catch (Exception ex) {
                if (LOG.isErrorEnabled()) {
                    LOG.error("Failed using StripPTag. ", ex);
                }
                throw new JspException(ex);
            }
        }
        return EVAL_PAGE;
    }
}

还有我自己的OpenCMS服务器。tld：

<?xml version="1.0" encoding="ISO-8859-1"?>

<!DOCTYPE taglib
  PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.2//EN"
  "http://java.sun.com/dtd/web-jsptaglibrary_1_2.dtd">

<taglib>
    <tlib-version>0.1</tlib-version>
    <jsp-version>1.2</jsp-version>
    <short-name>opencmsserver</short-name>
    <uri>http://www.opencmsserver.com/taglib/cms</uri>
    <display-name>OpenCms JSP standard taglib</display-name>
    <description>

    </description>

    <tag>
        <name>stripPTag</name>
        <tag-class>com.opencmsserver.taglib.StripPTag</tag-class>
        <body-content>JSP</body-content>
        <description>
            This tag stripts the p-tag from the surrounded content.
        </description>
    </tag>         

</taglib>

然后我在我的网站上引用它。xml:

<!  Begin: Custom SYSVISION OpenCmsServer lib  >      
<taglib>
    <taglib-uri>http://www.opencmsserver.com/taglib/opencmsserver</taglib-uri>
<taglib-location>/WEB-INF/opencmsserver.tld</taglib-location>
</taglib>

在jsp中，您只需用以下内容将其包围：

<opencmsserver:stripPTag>Some content<p>with a paragraph</opencmsserver:stripPTag>

（别忘了在jsp标题部分中引用这个标记库）
