springMvc 中 Excel批量数据上传，利用POI解析数据保存入数据库 及模板文件下载

Jsp页面：

<div id="ss" style="padding:5px; width:410px; height:220px">
<form id="addequipForm" class="formee"  name="addequipForm" action="${pageContext.request.contextPath}/equip/save.do" method="post"  enctype="multipart/form-data">
<table align="left">
<tr><td style="height: 15px;"></td></tr>
<tr>
导入数据需先下载<a href="${pageContext.request.contextPath }/equip/download.do"><span style="color:red">【模板数据】</span></a>，并认真填写后再进行添加，</br>否则有可能导致添加失败！
<td>文件地址：</td>
<td><input name="file" id="addequip" type="file" value="" /></td>
</tr>
<tr><td style="height: 10px;"></td></tr>
<tr>
<td colspan="1"><a href="javascript: void(0);" class="easyui-linkbutton" data-options="toggle:true,group:'g1'" onclick="save();">添  加</a></td>
</tr>
</table>
</form>
</div>

Js代码：

//修改
function save(){
document.forms.addequipForm.submit( );
}

Equipment实体类：

@Entity
@Table(name = "T_EQUIPMENT")
public class Equipment  extends UUIDEntity {	//uuid自动生成，可以不写
private static final long serialVersionUID = 3283027241644822122L;
@Column(name="CODE")
private String code;	//设备编号
@Column(name="TYPE")
private String type;	//设备类型
@Column(name="USERNAME")
private String username;		//用户名字
@Column(name="ADDRESS")
private String address;		//用户住址
@Column(name="DISDATE")
private Date disDate;		//发放时间
@Column(name="MEMO")
private String memo;		//备注
//提供getter 和setter方法，快捷键alt+shift+ s 再按 r键
//重写tostring方法，快捷键alt+shift+ s 再按 s键
}
@MappedSuperclass
@AttributeOverride(name="id",column=@Column(name="id"))
public abstract class UUIDEntity extends IDEntity {

@Id
@Column(name="id")
@GenericGenerator(name="genericID", strategy="uuid")
@GeneratedValue(generator="genericID")
private String id;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
}

Controller 层：

@RequestMapping("/save")
public String savefile(@RequestParam(value = "file", required = false) MultipartFile file, HttpServletRequest request, ModelMap model) {
String fileName = file.getOriginalFilename();		//原始文件名
//System.out.println("原始文件名------->"+fileName);
String uploadPath = PropertiesUtil.getProperty("xlsxUploadSavePath");	//这里可以写死一个本地磁盘路径： 如 d:/upload/xlsx等（具体到xlsx文件夹下面）

System.out.println("配置文件uploadPath------>"+uploadPath);
//	String ss = request.getSession().getServletContext().getRealPath(uploadPath);
String newFileName = null;
String newFilePath = null;
if(!file.isEmpty()){
//加上分隔符号
String newDatePath =  File.separator+ DateUtil.getStringDateYMD()+ File.separator;	//加上分隔符号
//  System.out.println("日期格式的文件夹------->"+newDatePath);
String savepath = uploadPath + newDatePath;
// System.out.println("保存路径------->"+savepath);
String fileType = fileName.substring(fileName.lastIndexOf("."), fileName.length());
// System.out.println("后缀名------->"+fileType);
//如过是 2007 文件开始保存
if(".xlsx".equals(fileType)){

附：

注：excel中所有的内容必须为文字字符：在excel的下发时间栏目表格内加一个英文的“’”号，

上文中的form 是 Equipment 的具体实例。小心被误导.....

批量保存的源码：

@Transactional(propagation=Propagation.REQUIRED)
public void addBatch(List<T> list) {
for(T t:list){
baseDao.add(t);
}
}

baseDao中：

public void add(T entity) {
getHibernateTemplate().save(entity);
}

DateUtil：

public static String getStringDateYMD(){
SimpleDateFormat format=new SimpleDateFormat("yyyy-MM-dd");
String newDate=format.format(new Date());
return newDate;
}

文件下载：

jsp 页面：

<td id="downfile" colspan="3"><a href="${pageContext.request.contextPath }/equip/download.do" class="easyui-linkbutton"
 data-options="toggle:true,group:'g1'">点击下载</a></td>

Controller：

@RequestMapping("/download")
public void downloadFile(String fileName,HttpServletRequest  request,HttpServletResponse response){

response.setContentType("application/x-download; charset=utf-8");//1
String xlsxDemoName = PropertiesUtil.getProperty("xlsxDemoName");		//这里是要下载的模板文件名，可以写死
String xlsxUploadSavePath =  PropertiesUtil.getProperty("xlsxUploadSavePath");//这是要下载文件的路径，上线后就是另外的服务器地址，调试是本地磁盘，如d:/XXX
//	String ss = request.getSession().getServletContext().getRealPath(uploadPath);
try {
if (request.getHeader("User-Agent").toLowerCase().indexOf("firefox") > 0) {
xlsxDemoName = new String(xlsxDemoName.getBytes("UTF-8"), "ISO8859-1"); // firefox浏览器
response.setHeader("Content-disposition", "attachment; filename="+xlsxDemoName);
xlsxDemoName = new String(xlsxDemoName.getBytes("ISO-8859-1"),"UTF-8");
} else if (request.getHeader("User-Agent").toUpperCase().indexOf("MSIE") > 0) {
response.setHeader("Content-disposition", "attachment; filename="+xlsxDemoName);
xlsxDemoName = URLEncoder.encode(xlsxDemoName, "UTF-8");// IE浏览器
xlsxDemoName = new String(xlsxDemoName.getBytes("ISO-8859-1"),"UTF-8");
}else if (request.getHeader("User-Agent").toUpperCase().indexOf("CHROME") > 0) {
xlsxDemoName = new String(xlsxDemoName.getBytes("UTF-8"), "ISO8859-1");// 谷歌
response.setHeader("Content-disposition", "attachment; filename="+xlsxDemoName);
xlsxDemoName = new String(xlsxDemoName.getBytes("ISO-8859-1"),"UTF-8");
}else{
response.setHeader("Content-disposition", "attachment; filename="+URLEncoder.encode(xlsxDemoName,"utf-8"));
}

//	response.setHeader("Content-disposition", "attachment; filename="+URLEncoder.encode(xlsxDemoName,"utf-8"));
} catch (Exception e1) {
e1.printStackTrace();
}

try {
File file=new File(xlsxUploadSavePath+File.separator+xlsxDemoName);
InputStream inputStream=new FileInputStream(file);
OutputStream os=response.getOutputStream();
byte[] b=new byte[1024];
int length;
while((length=inputStream.read(b))>0){
os.write(b,0,length);  //os会自动关流
}
inputStream.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}

}

注：

访问浏览器的判断有点冗余：读者自行改善，我的这个项目，没法改，IE8就是不进它的循环里面，所有没办法，瞎写了，不过还是能正常下载.....

本人菜鸟一枚。有不正之处，希望大家指正交流，Q我：326082040，thanks ！
