FCKeditor的详细配置

1，下载FCKeditor 2.6.3
2，下载fckeditor-java-2.4.1-bin.zip
3，下载fckeditor-java-demo-2.4.1.war （可作为参考）

第一步是fckeditor使用配置文件
在FCKeditor文件夹里新建一个myconfig.js（它可覆盖fckconfig.js 的配置）
以后可根据实际的需要来配置

第二部是文件上传的配置
FCKeditor默认是不支持文件上传的，需要我们手动配置
1，在web.xml 输入

Java代码

1. <servlet>   
2.       <servlet-name>Connector</servlet-name>   
3.         <servlet-class>   
4.           net.fckeditor.connector.ConnectorServlet   
5.       </servlet-class>   
6.       <load-on-startup>1</load-on-startup>   
7.     </servlet>   
8.     ...   
9.     <servlet-mapping>   
10.       <servlet-name>Connector</servlet-name>   
11.       <url-pattern>   
12.         /fckeditor/editor/filemanager/connectors/*   
13.       </url-pattern>   
14.     </servlet-mapping>  

<servlet>      <servlet-name>Connector</servlet-name>        <servlet-class>          net.fckeditor.connector.ConnectorServlet      </servlet-class>      <load-on-startup>1</load-on-startup>    </servlet>    ...    <servlet-mapping>      <servlet-name>Connector</servlet-name>      <url-pattern>        /fckeditor/editor/filemanager/connectors/*      </url-pattern>    </servlet-mapping>

2，新建一个 fckeditor.properties 文件 in your classpath :
输入

Java代码

1. connector.userActionImpl=net.fckeditor.requestcycle.impl.UserActionImpl  

connector.userActionImpl=net.fckeditor.requestcycle.impl.UserActionImpl

第三步是解决上传中文乱码的问题
我们新建一个类 比如 com.fck.fckeditor.ConnectorServlet

Java代码

1. package com.fck.fckeditor;

然后在WEB.XML 里修改为

Java代码

第四步是：限制上传文件类型，
根据 net.fckeditor.handlers  包下的default.properties 的配置
在我们新建的fckeditor.properties设置，用以覆盖defualt.properties里的设置
