跟据客户的要求，需要开发一套包括图形的报表，还需要导出WORD
图表需要这样：
这样：
这样：
还有这样：
接下来是实现思路:
以往用的最多的就是JFreechart,手上也有实现各种图形的资源，但是领导说用它做的图形太丑了, 所以没什么卵用。
FusionCharts到是漂亮，但是没有办法实现上述图表，客户也不能接受替代方案，同样没什么卵用
然后就是百度ECharts，漂亮、功能强大、灵活性强（JS/HTML5实现,可以随意更改源码）, 但是有些功能不支待IE8， 还是没什么卵用
想了很多方法，最后又回到了原点，客户要生成Office, 就让Office给我们做，虽然Java对操作图表还没有什么好的方法，但是jacob是可以操作宏，我们通过宏实现所有图表功能。
1、 制作Excel图表模板
制作图表看起来简单，但是做起来相当的慢，好在客户提供一些类似图表，我做了一些调整就可以了 膜拜。。。。。
还有就是网上一堆的制作图表的教程，就不记录了。
2、 通过POI填充数据到Excel
1 /** 2 * 通过填充excel 生成图表 3 * @param list 图标数据 4 * @param inFile 模板文件 5 * @param outFile 输出文件 6 * @return 7 * @throws Exception 8 */ 9 public static void createChart(List<Map> list, String inFile,String outFile) { 10 if(list == null) list = new ArrayList(); 11 12 System.out.println("图表个数" + list.size()); 13 System.out.println("源文件路径" + inFile); 14 System.out.println("图表个数" + outFile); 15 16 try { 17 // 读取模板 18 FileInputStream is = new FileInputStream(inFile); 19 HSSFWorkbook wbs = new HSSFWorkbook(is); 20 21 int sheetIndex; 22 HSSFSheet sheet; //sheet 23 int rowIndex; 24 HSSFRow row; //行 25 int cellIndex; 26 HSSFCell cell; //列 27 String value; 28 float fvalue; 29 String valStr = "^[-+]?(([0-9]+)([.]([0-9]+))?|([.]([0-9]+))?)$"; 30 31 List<Integer> sheetList = new ArrayList(); 32 for(Map tempMap:list) { 33 // 读取工作表(data) 34 sheetIndex = Integer.parseInt(tempMap.get("SHEETINDEX") + ""); 35 sheet = wbs.getSheetAt(sheetIndex-1); 36 sheetList.add(sheetIndex); 37 38 /* 39 int i = 0; 40 List<HSSFPictureData> pictures = wbs.getAllPictures(); 41 for (HSSFPictureData picData : pictures) { 42 String ext = picData.suggestFileExtension(); 43 byte[] data = picData.getData(); 44 System.out.println(data.length); 45 46 47 //savePic(row, picData); 48 /* 49 String ext = picData.suggestFileExtension(); 50 51 byte[] data = picData.getData(); 52 if (ext.equals("jpeg")) { 53 FileOutputStream out = new FileOutputStream( 54 "D:\Users\Fancy1_Fan\桌面\work\pict" + i + ".jpg"); 55 out.write(data); 56 out.close(); 57 } 58 if (ext.equals("png")) { 59 FileOutputStream out = new FileOutputStream( 60 "D:\Users\Fancy1_Fan\桌面\work\pict" + i + ".png"); 61 out.write(data); 62 out.close(); 63 }*//* 64 i++; 65 }*/ 66 67 //添加行 68 rowIndex = Integer.parseInt(tempMap.get("ROWINDEX") + ""); 69 row = sheet.getRow(rowIndex-1); 70 if(row == null) row = sheet.createRow(rowIndex-1); 71 72 //列 73 cellIndex = Integer.parseInt(tempMap.get("CELLINDEX") + ""); 74 cell = row.getCell(cellIndex-1); 75 76 value = tempMap.get("DATAINFO") + ""; 77 if(value.matches(valStr)) { 78 fvalue = Float.parseFloat(value); 79 80 cell.setCellValue(fvalue); 81 } else { 82 cell.setCellValue(value); 83 } 84 //cell.setCellValue(tempMap.get("DATAINFO") + ""); //数据列 85 } 86 for(int temp:sheetList) { 87 sheet = wbs.getSheetAt(temp-1); 88 sheet.setForceFormulaRecalculation(true); 89 } 90 91 // 输出文件 92 FileOutputStream os = new FileOutputStream(outFile); 93 wbs.write(os); 94 is.close(); 95 os.close(); 96 } catch (Exception e) { 97 e.printStackTrace(); 98 } 99 }
3、 生成宏
我的基本思路是把所有生成的图片复至到一个指定Sheet, 然后Java代码只要到这个Sheet里获取图形
Sheets("QPLJYFJWXSQK").Select ActiveSheet.ChartObjects("图表 1").Activate ActiveChart.PlotArea.Select ActiveChart.ChartArea.Copy Sheets("CHART").Select Range("A41").Select ActiveSheet.Pictures.Paste.Select ActiveCell.FormulaR1C1 = "QPLJYFJWXSQK"
Sheets("QGJYFJLXSQK").Select Range("J13:S20").Select ' 复制位图 Selection.CopyPicture Appearance:=xlScreen, Format:=xlBitmap Sheets("CHART").Select Range("AA1").Select '粘贴为图片(问题:复制的位图自动添加边框线，通过裁减的方式删除边框线) ActiveSheet.Paste Selection.ShapeRange.PictureFormat.Crop.PictureOffsetX = -1 Selection.ShapeRange.PictureFormat.Crop.PictureOffsetY = -1 Selection.Copy Range("A1").Select ActiveSheet.Pictures.Paste.Select ActiveCell.FormulaR1C1 = "QGJYFJLXSQK"
只要会VBA 基本语法，其它的如果不会，可以通过录制宏得到
4、 调用宏
先提供工具类
1 package com.wiseda.fc.utils; 2 3 import com.jacob.activeX.ActiveXComponent; 4 import com.jacob.com.ComThread; 5 import com.jacob.com.Dispatch; 6 import com.jacob.com.Variant; 7 8 public class JacobExcelUtils { 9 private static ActiveXComponent xl = null;

调用宏代码
1 public void excelPictureGrab() throws Exception { 2 this.targetFile = new File(targetFilePath); 3 4 //复制文件 5 FileUtils.copyFile(xlsFile, targetFile); 6 7 logger.info("文件复至完成"); 8 9 //生成带图形的 excel 10 JacobExcelUtils tool = new JacobExcelUtils(); 11 try { 12 tool.OpenExcel(targetFilePath, false, false); 13 14 logger.info("打开Excel"); 15 16 //执行宏 复制为图片 17 tool.callMacro("copyImg"); 18 19 logger.info("处理宏完成"); 20 } catch (Exception e) { 21 throw new Exception("执行宏出错," + e.getMessage()); 22 // TODO: handle exception 23 } finally { 24 // 关闭流 25 tool.CloseExcel(false, true); 26 } 27 }
5、 获取图表
1 //获取图片字节流 2 public static String getPic(String fileUrl,String backupUrl) throws Exception { 3 StringBuffer results = new StringBuffer(); 4 5 File tfdir = new File(backupUrl); 6 if (!tfdir.exists()) tfdir.mkdirs(); 7 8 InputStream inp = new FileInputStream(fileUrl); 9 HSSFWorkbook workbook = (HSSFWorkbook) WorkbookFactory.create(inp); 10 11 List<HSSFPictureData> pictures = workbook.getAllPictures(); 12 HSSFSheet sheet = (HSSFSheet) workbook.getSheetAt(0); //所有图片都存在第一页 13 14 int i = 0; 15 for (HSSFShape shape : sheet.getDrawingPatriarch().getChildren()) { 16 HSSFClientAnchor anchor = (HSSFClientAnchor) shape.getAnchor(); 17 18 if (shape instanceof HSSFPicture) { 19 HSSFPicture pic = (HSSFPicture) shape; 20 int pictureIndex = pic.getPictureIndex()-1; 21 22 //图片名称 23 int row = anchor.getRow1(); 24 25 System.out.println(anchor.getCol1()); 26 27 HSSFCell picCell = sheet.getRow(row).getCell(anchor.getCol1()); 28 29 String picName = ""; 30 if(picCell != null) { 31 picName = picCell.getStringCellValue(); 32 } 33 34 35 logger.info(i + "--->row." + anchor.getRow1() + ":cell." + anchor.getCol1() + ":pictureIndex." + pictureIndex); 36 37 HSSFPictureData picData = pictures.get(pictureIndex); 38 39 //备份并返回 图片 40 if(picName != null && !"".equals(picName)) { 41 String result = BackupPic(picName, picData,backupUrl); 42 results.append(result); 43 results.append(","); 44 } 45 } 46 i++; 47 } 48 49 return results.toString(); 50 } 51 52 //备份图片 53 private static String BackupPic(String picName,PictureData pic,String backupUrl) throws Exception { 54 String result = ""; 55 56 String pngImgUrl,jpgImgUrl; 57 String ext = pic.suggestFileExtension(); 58 byte[] data = pic.getData(); 59 if (ext.equals("png")) { 60 61 pngImgUrl = backupUrl + picName + "." + ext; 62 FileOutputStream out = new FileOutputStream( 63 pngImgUrl); 64 out.write(data); 65 out.close(); 66 67 //转为 jpg 68 jpgImgUrl = backupUrl + picName + ".jpg"; 69 ConvertPngToJpg(pngImgUrl,jpgImgUrl); 70 71 result = picName + ":" + DatatypeConverter.printBase64Binary(data); 72 } 73 74 return result; 75 } 76 77 //压缩图片 把PND图片转JPG 78 private static void ConvertPngToJpg(String pngImgUrl,String jpgImgUrl) { 79 BufferedImage bufferedImage; 80 try { 81 82 //read image file 83 bufferedImage = ImageIO.read(new File(pngImgUrl)); 84 85 // create a blank, RGB, same width and height, and a white background 86 BufferedImage newBufferedImage = new BufferedImage(bufferedImage.getWidth(), 87 bufferedImage.getHeight(), BufferedImage.TYPE_INT_RGB); 88 newBufferedImage.createGraphics().drawImage(bufferedImage, 0, 0, Color.WHITE, null); 89 90 // write to jpeg file 91 ImageIO.write(newBufferedImage, "jpg", new File(jpgImgUrl)); 92 93 } catch (IOException e) { 94 95 e.printStackTrace(); 96 97 } 98 }
