form的search.do在struts-confgi.xml中如下定義
<action path="/search" type="net.skycity.action.SearchLogAction">
???????? <forward name="show" path="/search.jsp" redirect="true"/>
?</action>
SearchLogAction實現：
package net.skycity.action;

import java.util.List;

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

import net.skycity.blog.LogManager;
import net.skycity.util.WellsoonUtil;

import org.apache.commons.lang.StringUtils;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

public class SearchLogAction extends Action {
?
?public ActionForward execute(ActionMapping mapping,
??????????? ActionForm form, HttpServletRequest request,
??????????? HttpServletResponse response) throws Exception
??? {
??String author=request.getParameter("author");
??? ?String logTypeId=request.getParameter("logTypeId");
??? ?String state=request.getParameter("state");
??? ?String query=WellsoonUtil.transfer(request.getParameter("query")==null?"":request.getParameter("query"));
??? ?List logs=null;
??? ?if(!StringUtils.isEmpty(query)){
??? ??logs=LogManager.searchFor(logTypeId,state,author,query);
??? ?}else{
??? ??logs=LogManager.searchFor(logTypeId,state,author);
??? ?}
??? ?request.getSession().setAttribute("logs",logs);
??????? return mapping.findForward("show");
??? }

}

請自己添加jar文件：struts包,pg74.215.jdbc3.jar(我用的postgresql數據庫),lucene-1.4-final.jar,lucene-demos-1.4-final.jar,log4j,dom4j,hibernate2.jar,commons-pool-1.1.jar，commons-dbcp-1.1.jar，cglib-full-2.0.2.jar
