多個(gè)變量進(jìn)行導(dǎo)出代碼如下：

@GetMapping("/export")public String varExport(@ModelAttribute FileSaveVars params ) throws IOException, InvalidRangeException { // 1° 設(shè)置原始文件路徑+轉(zhuǎn)存文件路徑String filePath = "/Users/caowei/workspace/jszone/大氣系統(tǒng)/ncdemo/src/main/resources/static/MERRA2_400.tavg1_2d_flx_Nx.20180101.SUB.nc";String savePath = "/Users/caowei/workspace/test.nc"; // 2° 讀取文件NetcdfFile ncFile = NetcdfFile.open(filePath, null);// 3° 構(gòu)造輸出保存文件NetcdfFileWriter ncWrite = NetcdfFileWriter.createNew(NetcdfFileWriter.Version.netcdf4, savePath); // 4° 文件緯度for(Dimension dimension : ncFile.getDimensions()){ncWrite.addDimension(null, dimension.getName(), dimension.getLength());} // 5° 設(shè)置需要轉(zhuǎn)存的變量List<String> varNames = Arrays.asList("lon","lat","time","QLML");List<Variable> varArray = new ArrayList<>();for(String varName : varNames){Variable varObject = ncFile.findVariable(varName);Variable varVar = ncWrite.addVariable(null, varObject.getName().toString(), varObject.getDataType(),varObject.getDimensionsString());varVar.addAll(ncFile.findVariable(varName).getAttributes());varArray.add(varVar);} // 6° 創(chuàng)建ncWrite.create(); // 7° 變量賦值for(Variable varItem:varArray){Array varData = ncFile.findVariable(varItem.getName()).read();ncWrite.write(varItem, varData);} // 8°關(guān)閉保存ncWrite.close();return "OK";}
