JSP中fckeditor控件表情修改以及文件上传

来源：互联网发布：mac os x 10.11.3 dmg 编辑：程序博客网时间：2024/05/21 07:59

（一）fckeditor控件表情修改

fckconfig.js中的后面几个参数控制表情，你可以将下面几个参数拷贝到myconfig.js，并进行修改就可以了。

FCKConfig.SmileyPath    = FCKConfig.BasePath + 'images/smiley/msn/' ; //图片的路径 
//图片的名字（数组） 
FCKConfig.SmileyImages  = ['aa.jpg','regular_smile.gif','sad_smile.gif','wink_smile.gif','teeth_smile.gif','confused_smile.gif','tounge_smile.gif','embaressed_smile.gif','omg_smile.gif','whatchutalkingabout_smile.gif','angry_smile.gif','angel_smile.gif','shades_smile.gif','devil_smile.gif','cry_smile.gif','lightbulb.gif','thumbs_down.gif','thumbs_up.gif','heart.gif','broken_heart.gif','kiss.gif','envelope.gif'] ;
FCKConfig.SmileyColumns = 8 ;// 每行显示的个数 
FCKConfig.SmileyWindowWidth     = 320 ;//弹出窗口宽度 
FCKConfig.SmileyWindowHeight    = 210 ;//弹出窗口高度

如果想修改弹出的标签页面可以去fckeditor/editor/dialog/fck_smiley.html文件。

//注释掉下面语句
//dialog.SetAutoSize( true ) ;//根据页面内容的大小，修改当前窗口的合适大小

以及修改下面样式

<!--将style类型更换
        <body style="overflow: hidden">
-->
<body style="overflow: auto">

（二）fckeditor控件实现文件文件上传

在web.xml中添加下面配置

    <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>

在src目录下建立文件fckeditor.properties，并输入如下内容

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

重新发布项目，就可以实现服务器文件上传与浏览。

（三）fckeditor控件文件上传中文问题

上面虽然已经实现上传问题，单仍然存在中文乱码问题，具体解决办法如下：
自己新建一个ConnectorServlet，将源代码中原来ConnectorServlet的内容复制过来，并做简单修改。
图片名中文问题，解决方式如下：

（1）在dopost()方法中添加
    upload.setHeaderEncoding("utf-8");
（2）在创建文件夹时，也存在中文问题,需要在doget()方法中
String newFolderStr = UtilsFile.sanitizeFolderName(request.getParameter("NewFolderName"));
修改成
     String tmpStr=request.getParameter("NewFolderName");
     tmpStr=new String(tmpStr.getBytes("iso8859-1"),"utf-8");
     String newFolderStr = UtilsFile.sanitizeFolderName(tmpStr);

（3）虽然上面已经可以正常上传中文图片和创建中文文件夹，但是，中文图片却无法正常显示。
这里可以采用如下方式解决问题。上传以后采用其它非中文名称进行保存，这里采用
filename=UUID.randomUUID().toString()+"."+extension;来解决问题；
当然很多网站是采用当前日期生成对应文件名，这个也比较好。

                                uplFile.write(pathToSave);
                            else {

            }
        }
        out.print(ur);
        out.flush();
        out.close();
        logger.debug("Exiting Connector#doPost");
    }
}

然后将web.xml中的servlet进行修改，具体修改如下：

    <servlet>
      <servlet-name>Connector</servlet-name>
        <servlet-class>
          jCuckoo.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>

重新部署，发布就可以实现该功能。
