如何更改Liferay context path

来源：互联网发布：天天炫斗开挂软件编辑：程序博客网时间：2024/05/01 02:22

首先参考 Howto：windows上如何快速体验 liferay(http://liferay.javaeye.com/group/topic/325)
确保liferay能够正常运行，假设新的context为myportal
将liferay关闭后准备按照以下步骤修改

1.将${TOMCAT_HOME}/webapps下ROOT目录改名为myportal

2.修改myportal下index.html

代码

<meta content="0; url=/c" http-equiv="refresh">
<body onLoad="javascript:location.replace('/c')">
->
<meta content="0; url=c" http-equiv="refresh">
<body onLoad="javascript:location.replace('c')">

3.修改myportal/WEB-INF/web.xml

代码

<context-param>
<param-name>root_path</param-name>
<param-value>/</param-value>
</context-param>
->
<context-param>
<param-name>root_path</param-name>
<param-value>/myportal</param-value>
</context-param>

4.修改myportal/WEB-INF/classes/portal-ext.properties

代码

portal.ctx=/
->
portal.ctx=/myportal

5.修改myportal/html/js/editor/fckeditor/fckconfig.jsp

代码

FCKConfig.LinkBrowserURL = FCKConfig.BasePath + "filemanager/browser/liferay/browser.html?Connector=/html/js/editor/fckeditor/editor/filemanager/browser/liferay/connectors/jsp/connector?p_l_id=<%= plid %>";
FCKConfig.ImageBrowserURL = FCKConfig.BasePath + "filemanager/browser/liferay/browser.html?Type=Image&Connector=/html/js/editor/fckeditor/editor/filemanager/browser/liferay/connectors/jsp/connector?p_l_id=<%= plid %>";
->
FCKConfig.LinkBrowserURL = FCKConfig.BasePath + "filemanager/browser/liferay/browser.html?Connector=/myportal/html/js/editor/fckeditor/editor/filemanager/browser/liferay/connectors/jsp/connector?p_l_id=<%= plid %>";
FCKConfig.ImageBrowserURL = FCKConfig.BasePath + "filemanager/browser/liferay/browser.html?Type=Image&Connector=/myportal/html/js/editor/fckeditor/editor/filemanager/browser/liferay/connectors/jsp/connector?p_l_id=<%= plid %>";

重新启动liferay
http://localhost:8080/myportal查看新设置是否正常

另：
由于fckeditor中的某些代码被硬编码在java文件中，所以使用fckeditor时浏览服务器图像和浏览器文件时返回的url不正确
比如某个图像url是/myportal/image/image_gallery?img_id=1001，但是在使用fckeditor时返回的是/image/image_gallery?img_id=1001
见ImageCommandReceiver.java

代码

fileEl.setAttribute("url", "/image/image_gallery?img_id=" + image.getImageId());
