批量导入功能实现
批量导入功能《个人框架只作为参考》
颜色相同对应调用部分
1》在XXX-config.xml中定义xlsx文件保存路径
temp
2》在Util文件夹写一个PathUtil类来接收XXX-Config.xml文件中定义保存位置，
括号内容为XXX-Config.xml加粗斜体部分
public static String getFilesRealPath() throws Exception
{
String realPath = ConfigContext.getProperty( "business.files.real.path" ) ;
return getFilesPath( realPath ) ;
}
3》在Util文件夹中定义一个UploadUtil类来调用PathUtil中的方法
public static void uploadZip( HttpServletRequest request, HttpServletResponse response ) throws Exception
{
boolean isMultipart = ServletFileUpload.isMultipartContent( request ) ;
if( isMultipart )
{
FileItemFactory factory = new DiskFileItemFactory() ;
ServletFileUpload upload = new ServletFileUpload( factory ) ;
// 得到所有的表单域，它们目前都被当作FileItem
List fileItems = upload.parseRequest( request ) ;
String id = "" ;
String oldName = "" ;
String extName = "" ;
// 如果大于1说明是分片处理
int chunks = 1 ;
int chunk = 0 ;
FileItem tempFileItem = null ;
for( FileItem fileItem : fileItems )
{
if( fileItem.getFieldName().equals( "guid" ) )
{
id = fileItem.getString() ;
}
else if( fileItem.getFieldName().equals( "name" ) )
{
oldName = new String( fileItem.getString().getBytes( "ISO-8859-1" ), "UTF-8" ) ;
extName = oldName.substring( oldName.lastIndexOf( "." ) ) ;
}
else if( fileItem.getFieldName().equals( "chunks" ) )
{
chunks = NumberUtils.toInt( fileItem.getString() ) ;
}
else if( fileItem.getFieldName().equals( "chunk" ) )
{
chunk = NumberUtils.toInt( fileItem.getString() ) ;
}
else if( fileItem.getFieldName().equals( "file" ) )
{
tempFileItem = fileItem ;
}
}
String fileName = id + extName ;
// 临时目录用来存放所有分片文件
String tempDirPath = PathUtils.getFilesTempPath() + id ;
File tempDirFile = new File( tempDirPath ) ;
if( !tempDirFile.exists() )
{
tempDirFile.mkdirs() ;
}
// 分片处理时，前台会多次调用上传接口，每次都会上传文件的一部分到后台
File tempPartFile = new File( tempDirFile, fileName + "_" + chunk + ".part" ) ;
FileUtils.copyInputStreamToFile( tempFileItem.getInputStream(), tempPartFile ) ;
tempFileItem.delete() ;
// 所有分片都存在才说明整个文件上传完成
boolean uploadDone = true ;
for( int i = 0; i < chunks; i++ )
{
File partFile = new File( tempDirFile, fileName + "_" + i + ".part" ) ;
if( !partFile.exists() )
{
uploadDone = false ;
}
}
// 所有分片文件都上传完成，将所有分片文件合并到一个文件中
if( uploadDone )
{
// 创建上传文件最终存储目录
String destDirPath = PathUtils.getFilesTempPath() ;
File destDirFile = new File( destDirPath ) ;
if( !destDirFile.exists() )
destDirFile.mkdirs() ;
File destFile = new File( destDirPath, fileName ) ;
FileOutputStream destfos = new FileOutputStream( destFile, true ) ;
for( int i = 0; i < chunks; i++ )
{
File partFile = new File( tempDirFile, fileName + "_" + i + ".part" ) ;
FileUtils.copyFile( partFile, destfos ) ;
}
destfos.close() ;
// 删除临时目录中的分片文件
FileUtils.deleteQuietly( tempDirFile ) ;
Map resultMap = new HashMap() ;
resultMap.put( "fileId", id ) ;
resultMap.put( "fileName", oldName ) ;
resultMap.put( "fileType", extName.substring( 1 ).toUpperCase() ) ;
resultMap.put( "file_real_path", destFile.getPath() ) ;
response.getWriter().print( AjaxResult.withMap( resultMap ).getOutput() ) ;
}
}
}
4》在Action写一个写一个读取XLSX文件的方法并且把读取数据保存到rowMap中
public AjaxResult batchSave(AjaxParameter param){
Map result = new HashMap<>();
try{
List> fileDataList = param.getMapList( "filesData" ) ;
String filePath = "";
for( Map map : fileDataList )
{
filePath = FormatConvertor.parseString( map.get( "filePath" ) ) ;
}
File excelFile = new File( filePath ) ;
FileInputStream is = new FileInputStream( excelFile ) ;
Workbook workbook = WorkbookFactory.create( is ) ;
int sheetCount = 0 ; //获取第一个sheet的数据
Sheet sheet = workbook.getSheetAt( sheetCount ) ;
int rowCount = sheet.getLastRowNum() +1 ; // 获取总行数
List> rowMapList = new ArrayList>();
for( int r = 1; r < rowCount; r++ )
{
Map rowMap = new HashMap<>();
// 读取行
Row row = sheet.getRow( r ) ;
if(row == null)
continue;
int cellCount = row.getLastCellNum() ; // 获取总列数
// 遍历每一列
for( int c = 0; c < cellCount; c++ )
{
// 读取列
Cell cell = row.getCell( c ) ;
if( cell != null ){
String cellValue = BatchImportBase.getCellValue(cell);
if( c == 0)
rowMap.put("CostCode", cellValue); //对应实体类类名
if( c == 1 )
rowMap.put("CostRange", cellValue);//对应实体类类名
if( c == 2 )
rowMap.put("CostCompany", cellValue);//对应实体类类名
if( c == 3 )
rowMap.put("CostInstruction", cellValue);//对应实体类类名
/*if( c == 4)
rowMap.put("enable", cellValue);*/
}
}
rowMapList.add(rowMap);
}
int row = 0; //检索行
String resultMessage = "";
for( Map rowMap : rowMapList ){
boolean flag = true; //是否失败标志
String message = ""; //失败描述
row ++;
if(TextUtils.isBlank(rowMap.get("CostCode"))){
message += "字典目录为空";
flag = false;
}
if(TextUtils.isBlank(rowMap.get("CostRange"))){
message += "范围为空";
flag = false;
}
if(TextUtils.isBlank(rowMap.get("CostCompany"))){
message += "公司为空";
flag = false;
}
if(TextUtils.isBlank(rowMap.get("CostInstruction"))){
message += "简要说明为空";
flag = false;
}
if(!flag){
message = "第" + row + "行失败......" + message + "
";
resultMessage += message;
}
}
if(TextUtils.isBlank(resultMessage)){ //判断加载XLSX文件是否存在问题没有问题就导入，有问题就提示。
for( Map rowMap : rowMapList ){
BusinessCostCenterEntity detailEntity = new BusinessCostCenterEntity();
DataList list = businesscostcentermanager.List(rowMap.get("CostCode"), null);
if(null==list||list.size()==0){ //批量导入时没有的就新增，如果已经存在就覆盖，
detailEntity.setDelFlag(Constant.DEL_FLAG_NO);
detailEntity.setCostCode(rowMap.get("CostCode"));
detailEntity.setCostRange(rowMap.get("CostRange"));
detailEntity.setCostCompany(rowMap.get("CostCompany"));
detailEntity.setCostInstruction(rowMap.get("CostInstruction"));
detailEntity.setCreateUser(SecurityContext.getPrincipal().getIdentity());
} else {
detailEntity = list.get(0);
detailEntity.setCostRange(rowMap.get("CostRange"));
detailEntity.setCostCompany(rowMap.get("CostCompany"));
detailEntity.setCostInstruction(rowMap.get("CostInstruction"));
detailEntity.setModifyUser(SecurityContext.getPrincipal().getIdentity());
}
businesscostcentermanager.save(detailEntity);
}
result.put("result", "success");
result.put("message","导入成功
");
}else{
result.put("result", "fail");
result.put("message", resultMessage);
}
}catch (Exception e) {
e.printStackTrace();
}
return AjaxResult.withMap( result ) ;
}
}
Upload方法调用UploadUtil中的uploadZip方法
@RequestMapping(params="command=upload")
public void upload(HttpServletRequest request,HttpServletResponse response) throws Exception{
UploadUtils.uploadZip(request, response);
5》页面代码
