Pager類記錄頁面信息，用于和jsp頁面進行交互！
Action類如下。主要是給出sql，把page信息放到request中，提供給頁面使用。

package bu3.actionImpl;

import java.util.List;
import java.util.Map;

import bu3.action.OqcBadMessageAction;
import bu3.service.OqcBadService;
import bu3.tools.Pager;

import com.opensymphony.xwork.ActionContext;
import com.opensymphony.xwork.ActionSupport;

public class OqcBadMessageActionImpl extends ActionSupport implements
		OqcBadMessageAction {

	public Pager page;

	public String qcNo = "";
//qcMessage頁面列表數據
	public List qcMessage;

	public String qcDetial() {

		String hql = "from bu3.vo.VQcFromRepairInfo vf where vf.id.qcNo='"
				+ qcNo + "'";
		page.setHql(hql);
		page.setPageSize(3);
		Map map = (Map) ActionContext.getContext().get("request");
		map.put("page", page);
		qcMessage=page.getDataList();
		return SUCCESS;
	}

	public String getQcNo() {
		return qcNo;
	}

	public void setQcNo(String qcNo) {
		this.qcNo = qcNo;
	}

	public List getQcMessage() {
		return qcMessage;
	}

	public Pager getPage() {
		return page;
	}

	public void setPage(Pager page) {
		this.page = page;
	}

}

applicationContext中設定page和action的依賴關系

<bean id="OqcBadMessageAction"
		class="bu3.actionImpl.OqcBadMessageActionImpl" abstract="false"
		lazy-init="default" autowire="autodetect"
		dependency-check="default">
		<property name="page">
			<ref bean="page" />
		</property>
	</bean>

xwork.xml

<action name="OqcBadDetialMessage" class="OqcBadMessageAction"
			method="qcDetial">
			<result name="success">oqcBadDetial.jsp</result>

		</action>

最后jsp頁面

<%@ page language="java" import="java.util.*" pageEncoding="BIG5"%>
<%@ taglib prefix="ww" uri="/webwork"%>

<html>
	<head>
		<link rel=stylesheet href="../styles/main.css" type="text/css">
	</head>

	<body>
		<br>
		<table border>
			<ww:iterator value="qcMessage" status="away">

		</table>
		<center>
			<ww:if test="qcMessage.size()<1">

			</ww:if>
		</center>
		<br>
//根據request中Pager類的信息生成鏈接
		<ww:if test="#request.page.hasFirst">

		</ww:if>
		<br>
