attachlistaction.java

一段很有意义的源码,看了就知道,不信试一试啊!

package com.wondersgroup.basemodule.attachmentmanage.web.action;

import java.util.HashMap;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.ActionForm;

import com.wondersgroup.framework.core.bo.Page;

public class AttachListAction  extends BaseAction {

	private AttachService attachService;
	public ActionForward execute(ActionMapping mapping, ActionForm form,
			   HttpServletRequest request, HttpServletResponse response) {
		
			AttachForm attachForm = (AttachForm) form; 
			String Action=request.getParameter("action");
			attachService=(AttachService)this.getService("attachService", request);
			if("seefile".equals(Action)){

			}else if("deletefile".equals(Action)){

				attachBO.setId(Long.valueOf(request.getParameter("id")).longValue());
				attachService.deleteAttach(attachBO);
