思路：
1、action獲取到數據，封裝成list
2、通過ACtionContext或者Request將list放入其中
3、在jsp頁面讀取
底層的代碼這裏不講述了，用的是mybatis與spring
Action代碼：
package com.bs.view.action;
import java.io.UnsupportedEncodingException;
import java.util.List;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts2.ServletActionContext;
import com.bs.container.ServiceProvider;
import com.bs.po.DataList;
import com.bs.service.DataService;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
/*
*@Author swxctx
*@time 2017年5月1日
*@Explain:獲取所有數據信息
*/
public class DataAllAction extends ActionSupport{
private static final long serialVersionUID = 1L;
/*加載applicationContext.xml*/
private DataService dataService = (DataService)ServiceProvider.getService(DataService.SERVICE_NAME);
private List<DataList> dataLists;
public List<DataList> getDataLists() {
return dataLists;
}
public void setDataLists(List<DataList> dataLists) {
this.dataLists = dataLists;
}
@Override
public String execute() throws Exception {
HttpServletRequest request = ServletActionContext.getRequest();
HttpServletResponse response = ServletActionContext.getResponse();
try {
request.setCharacterEncoding("utf-8");
response.setCharacterEncoding("utf-8");
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
/*獲取所有數據信息*/
dataLists = dataService.findAllData();//(調用service層的代碼)
//request.setAttribute("dataLists", dataLists);
ActionContext.getContext().put("dataLists", dataLists);
return "success";
}
}Jsp代碼：

pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
