baseaction.java

一段很有意义的源码,看了就知道,不信试一试啊!

package com.sofmit.tools;
import javax.servlet.http.HttpServletRequest;

import org.apache.struts.actions.DispatchAction;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;

public abstract class BaseAction extends DispatchAction {
    
	/**
	 * 根据service名称取得service实例.
	 * @param serviceName
	 * @return
	 */
	public Object getService(String serviceName,HttpServletRequest res){
		
		WebApplicationContext context=WebApplicationContextUtils.getWebApplicationContext(res.getSession().getServletContext());	
		return context.getBean(serviceName);
	}
	
	
}
