“程序包com.sun.image.codec.jpeg不存在“ 正解

问题现象

开发环境：jdk1.8 工具：idea、maven

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.7.0:compile (default-compile) on project center-strategy-facade-impl: Compilation failure: Compilation failure: *****:程序包com.sun.image.codec.jpeg不存在 问题代码 FileOutputStream out=null; try { //outPath文件输入绝对路径 out=new FileOutputStream(outPath); JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out); //bufferedImage JPEGEncodeParam param = encoder.getDefaultJPEGEncodeParam(bufferedImage); param.setQuality(100, true); encoder.encode(bufferedImage, param); out.close(); } catch(Exception e) { return false; }finally { try { out.close(); } catch (IOException e) { e.printStackTrace(); } }

解决后代码变为

程序包com.sun.image.codec.jpeg在jdk1.7之后都不支持。使用变通方法，使用ImageIO.write方法生成图片

FileOutputStream out=null; try { //outPath文件输入绝对路径 out=new FileOutputStream(outPath); ImageIO.setUseCache(false); ImageIO.write(bufferedImage,"jpg",out); out.close(); } catch(Exception e) { return false; }finally { try { out.close(); } catch (IOException e) { e.printStackTrace(); } } 获取文件绝对路径 上述的outPath可以通过以下方法获取，例如outPath=getFilePath(“classpath:static/images”)+"/temp.jpg"; private String getFilePath(String filePath){ File file = null; try { file = ResourceUtils.getFile(filePath); if (file==null){ return ""; } System.err.println(file.getPath()); return file.getPath(); } catch (FileNotFoundException e) { e.printStackTrace(); return ""; } }
