    }

    public void setContenttype(String contenttype) {
        this.contenttype = contenttype;
    }
}

视图做完之后做如下配置运行测试

package com.customer.action;

import com.opensymphony.xwork.ActionContext;
import com.opensymphony.xwork.ActionSupport;
import com.opensymphony.webwork.ServletActionContext;
import com.dboperate.ResultGather;
import org.apache.poi.hssf.usermodel.*;
import org.apache.poi.hssf.util.HSSFColor;

import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.ByteArrayInputStream;
import java.util.List;
import java.util.Map;

public class ExportExcelAction extends ActionSupport {
    private HSSFWorkbook workbook;

    public String execute() throws Exception {
        return SUCCESS;
    }

    public String product() throws Exception {
        try {
            workbook = new HSSFWorkbook();
            HSSFSheet sheet = workbook.createSheet();

            workbook.setSheetName(0, "厂商产品", (short) 1);
            HSSFRow row = sheet.createRow((short) 0);

            HSSFCell cell0 = row.createCell((short) 0);
            HSSFCell cell1 = row.createCell((short) 1);
            HSSFCell cell2 = row.createCell((short) 2);
            HSSFCell cell3 = row.createCell((short) 3);
            HSSFCell cell4 = row.createCell((short) 4);
            HSSFCell cell5 = row.createCell((short) 5);
            HSSFCell cell6 = row.createCell((short) 6);
            HSSFCell cell7 = row.createCell((short) 7);
            HSSFCell cell8 = row.createCell((short) 8);
            HSSFCell cell9 = row.createCell((short) 9);

            cell0.setEncoding(HSSFCell.ENCODING_UTF_16);//这里是设置编码保证中文正常显示
            cell1.setEncoding(HSSFCell.ENCODING_UTF_16);
            cell2.setEncoding(HSSFCell.ENCODING_UTF_16);
            cell3.setEncoding(HSSFCell.ENCODING_UTF_16);
            cell4.setEncoding(HSSFCell.ENCODING_UTF_16);
            cell5.setEncoding(HSSFCell.ENCODING_UTF_16);
            cell6.setEncoding(HSSFCell.ENCODING_UTF_16);
            cell7.setEncoding(HSSFCell.ENCODING_UTF_16);
            cell8.setEncoding(HSSFCell.ENCODING_UTF_16);
            cell9.setEncoding(HSSFCell.ENCODING_UTF_16);

            cell0.setCellValue("厂商名");
            cell1.setCellValue("产品名");
            cell2.setCellValue("重量");
            cell3.setCellValue("星级");
            cell4.setCellValue("parama");
            cell5.setCellValue("paramb");
            cell6.setCellValue("paramc");
            cell7.setCellValue("paramd");
            cell8.setCellValue("状态");
            cell9.setCellValue("备注");

        } catch (Exception e) {
        }
        return SUCCESS;
    }

    public HSSFWorkbook getWorkbook() {
        return workbook;
    }

}

Xwork.xml中配置加入

        <result-type default="true" name="freemarker"
            <result-type name="excel" class="com.customer.resulttype.ExcelResult"/>
        </result-types>

 <action name="exportExcel" class="com.customer.action.ExportExcelAction">

            <result name="success" type="excel">
                <param name="filename">productparam>
               
            </result>

        </action>

    public String update() throws Exception {
        ....
    }

    public String delete() throws Exception {
        ....
    }

    public String list() throws Exception {
        ....
    }

DAO
下面是DAO接口
public interface BaseDao {
    public int insert(Object form);
    public int update(Object form);
    public int delete(Object form);
    public int delete(int[] id);//这里是为了支持批量删除
    public Map getInfo(Object form);
    public List getList();
    public void getList(Pagination page);//这里没有返回值，内详。。。。
}

EXTENDS
扩展部分
1 BaseAction
这里增加了一些公用方便的功能，便于其他ACTION继承，共用
2 DaoSupport
这里也是一些公用的功能，Dao中用的大部分SQL都是配置在外部配置文件中


3DaoFactory
public class DaoFactory {
    public static BaseDao getDao(String daoKey){
        if("user".equals(daoKey)) //这样的方式可以通过在XWORK.XML中配置ACTION使用哪个DAO（静态注入）
            return new UserDao();
        else
            return null;

    }
}


数据库是MYSQL5

CREATE TABLE `usertbl` (                                                                                                                                                                                                                                                                                                                
           `User_ID` int(11) NOT NULL auto_increment,                                                                                                                                                                                                                                                                                            
           `username` varchar(50) default NULL,                                                                                                                                                                                                                                                                                                  
           `password` varchar(50) default NULL,

           PRIMARY KEY  (`User_ID`)

学习的时候看了网上的一些配置教程，没有达到想要的结果
查了好多资料才弄出来，随后后自己整理出一个配置方法

web.xml 
// 这里不需要配置字符过滤，网上有的例子加了，实际上
webwork.properties里设置如下就可以了页面也是GBK
webwork.locale=zh_CN
webwork.i18n.encoding=GBK

BlogUserDao.java
---------------------------------------------------------------------------
package com.jsblog.dao;

import org.springframework.orm.hibernate.support.HibernateDaoSupport;
import org.springframework.orm.hibernate.HibernateCallback;
import org.springframework.orm.hibernate.SessionFactoryUtils;
import com.jsblog.BlogUserForm;

import java.io.Serializable;
import java.util.List;

import net.sf.hibernate.HibernateException;
import net.sf.hibernate.Session;

public class BlogUserDao extends HibernateDaoSupport implements BaseDao {

    public void insert(BlogUserForm bloguser) {
        getHibernateTemplate().save(bloguser);
    }

}

第一种用ActionContext类，所有的参数都从这里ActionContext.getContext().getParameters()取
他返回的是一个Map类型
Map param= ActionContext.getContext().getParameters();
如果有一个提交过来的username
那就可以这样写
param.get("username");不过这里要注意一下param.get("username")是一个String数组(为什么要返回数据我也不知道，我从weblogic窗口看到param.get("username")被out出来Ljava.lang.String，忙活了半天)

  String value[] = (String[])param.get("username");
  String username = "";
  for(int i=0;i<value.length;i++)
  {
   username +=value[i];
  }
这样就可以得到正确的username了

第二种方法是直接把request引用进来

ServletActionContext.getRequest().getParameter("username")
ServletActionContext.getRequest()就是httpservletrequest
这个类再import com.opensymphony.webwork.ServletActionContext
用起来方便些

刚刚接触了FreeMarker觉得不错

做了个小例子
刚刚接触了FreeMarker觉得不错做了个小例子,没有用到jsp和jsptag

首先建立个数据表里面有username,password两个字段自己随便加几条数据
建立一个webwork  action    TestAction.java
在xwork.xml里加入如下内容
----------------------------------------
     
      /test.flt
    
----------------------------------------
TestAction.java代码如下
--------------------------------------------------
package com.action;

import com.opensymphony.xwork.ActionSupport;
import java.util.*;
import com.ResultGather;

public class TestAction extends ActionSupport
{
 private List lis;
 private ResultGather rs;
 public List getLis()
 {
  return this.lis;
 }
 public String execute() throws Exception
 {
  rs = new ResultGather();
  lis = rs.selectRS("select * from userbasedatum");//数据结果我是用List,HashMap封装的,HashMap存的是单条记录
  return SUCCESS;
 }
}

-------------------------------------------------------------------------------------------------------------------
ResultGather.java代码如下
----------------------------------------------------------
package com;

import conn.DBConnManager;//数据库连接池
import java.sql.*;
import java.util.*;

public class ResultGather
{
 private String sql;
 public ResultGather()
 { 
 }
 public ResultGather(String sqlcom)
 {
  this.sql=sqlcom;
 }
 public List selectRS(String sqlStr)
 {
  this.sql = sqlStr;
  return selectRS();
 }
 public List selectRS() //数据结果在这里装入List和Map
 {
  List rsall = new ArrayList();
  DBConnManager conn = null;
  Connection  con = null;
  Statement stmt = null;
  ResultSet rs = null;
  Map rsTree;
  try{
   conn = DBConnManager.getInstance();
   con = conn.getConnection("mssql");
   stmt = con.createStatement();
   rs = stmt.executeQuery(sql);
   ResultSetMetaData rsmd = rs.getMetaData();
   int numberOfColumns = rsmd.getColumnCount();
   while(rs.next())
   {
   rsTree = new HashMap(numberOfColumns);
    for(int r=1;r    {
     rsTree.put(rsmd.getColumnName(r),rs.getObject(r)); 
     
    }
    rsall.add(rsTree);
   }
   
  }catch(java.lang.Exception ex){
   ex.printStackTrace();
  }finally{
   try{
    if(rs!=null)
     rs.close();
    if(stmt!=null)
     stmt.close();
    if(conn!=null)
     conn.releaseConnection("mssql",con);
   }catch(Exception e){
    System.out.println(e);
   } 
  }
  return rsall;
 }
 }
-----------------------------------------------------------------------------------------------
test.flt代码如下
-----------------------------------------------------------------------------------------
<#list lis as x>
${x.username},
${x.password}

</#list>
     //freemarker用法网上有相关介绍
-------------------------------------------------------------------------------------

OK 完成了 没有用到jsp<%.....%>和jsptag
用这个例子做一点修改就可以具有分页用能了
