JAVA WEB 实现google suggest的功能 前台使用AJAX 后台是action 使用MYSQL数据库 ECLIPSE导入直接可以进行测试

package org.hnylj.ajax.action;

import java.io.PrintWriter;

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

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.hnylj.db.DbManager;

/**
 * 根据前台输入异步从后台获取数据的Action
 * @编写者：hnylj
 *
 */
public class SuggestAction extends Action {

	private DbManager dbManager;
	
	public ActionForward execute(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response)
			throws Exception {
		String param = request.getParameter("txtValue");
		dbManager = new DbManager();
		String result = dbManager.searchSuggest(param);
		PrintWriter out = response.getWriter();
		out.print(result);
		out.flush();
