我在red5做白板应用.示例代码如下

package com.free.whiteboard;

this.createSharedObject(app, "freehandSO", false); 
//Shared object for freehand drawing    
app.setAttribute("freehand" , new FreeHandDrawing(this));

我说,在最后一行我得到了错误

"The type org.springframework.core.io.support.ResourcePatternResolver 
cannot be resolved. It is indirectly referenced from   required 
.class files"..
