步一：建立ArticleDao.java類

public class ArticleDao {
    public Integer getAllObjectNum(String keywords) throws Exception{
        QueryParser queryParser = new QueryParser(LuceneUtil.getVersion(),"content",LuceneUtil.getAnalyzer());
        Query query = queryParser.parse(keywords);
        IndexSearcher indexSearcher 
 
= new IndexSearcher(LuceneUtil.getDirectory());
        TopDocs topDocs = indexSearcher.search(query,3);
        return topDocs.totalHits;
    }
    public List<Article> findAllObjectWithFY(String keywords,Integer start,Integer size) throws Exception{
        List<Article> articleList = new
 
 ArrayList<Article>();
        QueryParser queryParser = new QueryParser(LuceneUtil.getVersion(),"content",LuceneUtil.getAnalyzer());
        Query query = queryParser.parse(keywords);
        IndexSearcher indexSearcher = new IndexSearcher(LuceneUtil.getDirectory());
        TopDocs topDocs 
 
= indexSearcher.search(query,100000000);
        int middle = Math.min(start+size,topDocs.totalHits);
        for(int i=start;i<middle;i++){
            ScoreDoc scoreDoc = topDocs.scoreDocs[i];
            int no = scoreDoc.doc;
            Document document = indexSearcher.doc(no);
            Article article = (Article) LuceneUtil.document2javabean(document,Article.class);
            articleList.add(article);
        }
        return articleList;
    }
}

   步二：建立PageBean.java類

public class PageBean {
    private Integer allObjectNum;
    private Integer allPageNum;
    private Integer currPageNum;
    private Integer perPageNum = 2;
    private List<Article> articleList = new ArrayList<Article>();
    public PageBean(){}
    public Integer getAllObjectNum() {
        return allObjectNum;
    }
    public void setAllObjectNum(Integer allObjectNum) {
        this.allObjectNum = allObjectNum;
        if(this.allObjectNum % this.perPageNum == 0){
            this.allPageNum = this.allObjectNum / this.perPageNum;
        }else{
            this.allPageNum = this.allObjectNum / this.perPageNum + 1;
        }
    }
    public Integer getAllPageNum() {
        return allPageNum;
    }
    public void setAllPageNum(Integer allPageNum) {
        this.allPageNum = allPageNum;
    }
    public Integer getCurrPageNum() {
        return currPageNum;
    }
    public void setCurrPageNum(Integer currPageNum) {
        this.currPageNum = currPageNum;
    }
    public Integer getPerPageNum() {
        return perPageNum;
    }
    public void setPerPageNum(Integer perPageNum) {
        this.perPageNum = perPageNum;
    }
    public List<Article> getArticleList() {
        return articleList;
    }
    public void setArticleList(List<Article> articleList) {
        this.articleList = articleList;
    }
}

步三：建立ArticleService.java類

public class ArticleService {
    private ArticleDao articleDao = new ArticleDao();
    public PageBean fy(String keywords,Integer currPageNum) throws Exception{
        PageBean pageBean = new PageBean();
        pageBean.setCurrPageNum(currPageNum);
        Integer allObjectNum = articleDao.getAllObjectNum(keywords);
        pageBean.setAllObjectNum(allObjectNum);
        Integer size = pageBean.getPerPageNum();
        Integer start = (pageBean.getCurrPageNum()-1) * size;
        List<Article> articleList = articleDao.findAllObjectWithFY(keywords,start,size);
        pageBean.setArticleList(articleList);
        return pageBean;
    }
}

步四：建立ArticleServlet.java類

public class ArticleServlet extends HttpServlet {
    public void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {
        try {
            request.setCharacterEncoding("UTF-8");
            Integer currPageNum = Integer.parseInt(request.getParameter("currPageNum"));
            String keywords = request.getParameter("keywords");
            ArticleService articleService = new ArticleService();
            PageBean pageBean = articleService.fy(keywords,currPageNum);
            request.setAttribute("pageBean",pageBean);
            request.getRequestDispatcher("/list.jsp").forward(request,response);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

步五：匯入EasyUI相關的js包的目錄

步六：在WebRoot目錄下建立list.jsp

<%@ page language="java" pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

  <body>
  
  
      <!-- 輸入區 -->
    <form action="${pageContext.request.contextPath}/ArticleServlet?currPageNum=1" method="POST">
        輸入關健字：<input type="text" name="keywords" value="傳智" maxlength="4"/>
        <input type="button" value="提交"/>
    </form>
     
     
     <!-- 顯示區 -->
    <table border="2" align="center" width="70%">
        <tr>
            <th>編號</th>
            <th>標題</th>
            <th>內容</th>
        </tr>
        <c:forEach var="article" items="${pageBean.articleList}">
            <tr>
                <td>${article.id}</td>
                <td>${article.title}</td>
                <td>${article.content}</td>
            </tr>        
        </c:forEach>
    </table>


    <!-- 分頁元件區 -->
    <center>    
        <div id="pp" style="background:#efefef;border:1px solid #ccc;width:600px"></div> 
    </center>
    <script type="text/javascript">
        $("#pp").pagination({ 
            total:${pageBean.allObjectNum}, 
            pageSize:${pageBean.perPageNum},
            showPageList:false,
            showRefresh:false,
            pageNumber:${pageBean.currPageNum}
        }); 
        $("#pp").pagination({
            onSelectPage:function(pageNumber){
    $("form").attr("action","${pageContext.request.contextPath}/ArticleServlet?currPageNum="+pageNumber);
            $("form").submit();    
            }
        });
    </script>
    <script type="text/javascript">
             $(":button").click(function(){
             $("form").submit();    
         });
     </script>
  </body>
</html>

步六：在WebRoot目錄下建立list2.jsp

<%@ page language="java" pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

        <input id="currPageNOID" type="hidden" name="currPageNO" value="1">
        <table border="2" align="center">
            <tr>
                <th>輸入關鍵字：</th>
                <th><input type="text" name="keywords" maxlength="4" value="${requestScope.keywords}"/></th>
                <th><input type="submit" value="站內搜尋"/></th>
            </tr>
        </table>
    </form>
    
    
    <!-- 輸出區 -->
    <table border="2" align="center" width="60%">
        <tr>
            <th>編號</th>
