后台接收图片处理时：
public String havePhotoToReport(){
try {
String a = jsonStr;
jsonStr =jsonStr.replace(""",""");
JSONObject obj = JSONObject.fromObject(jsonStr);
ClaimsImage[] claimsImages = null;
//获取ArrayObject
if (obj.has("images")) {
JSONArray imagesArray = obj.getJSONArray("images");
if (imagesArray.size()>0) {
SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd");
String dateStr = sdf.format(new Date(System.currentTimeMillis()));
String id =UUID.randomUUID().toString();
claimsImages = new ClaimsImage[ imagesArray.size()];
for (int i = 0; i < imagesArray.size(); i++) {
ClaimsImage ci = new ClaimsImage();
JSONObject img = JSONObject.fromObject(imagesArray.getString(i));
System.out.println("imageName"+i+":" + img.get("imageName"));
ci.setImageName(img.get("imageName").toString());
System.out.println("imageData"+i+":" + img.get("imageData"));
ci.setImageData(img.get("imageData").toString());
claimsImages[i]= ci;
String savePath="c:/imgupload/"+dateStr+"/";
String newFileName=id+"_"+ci.getImageName();
String thumbnail =id+"_"+ci.getImageName().substring(0, ci.getImageName().lastIndexOf(".") )+"_thumb"+ci.getImageName().substring(ci.getImageName().lastIndexOf(".")+1);
base64SaveFile(ci, savePath, newFileName, thumbnail);
}
message.put("errorMsg", "文件上传成功");
message.put("errorCode","0000");
//return "error";
return MESSAGE;
}
}
} catch (IOException e) {
e.printStackTrace();
message.put("errorMsg", "文件上传失败");//出参错误信息
message.put("errorCode","0001");
//return "error";
return MESSAGE;
}
return SUCCESS;
}
private static void base64SaveFile(ClaimsImage ci, String savePath, String newFileName, String thumbnail) throws IOException {
File f = new File(savePath, newFileName);
if (!f.getParentFile().exists()){
f.getParentFile().mkdirs();
}
//使用BASE64对图片文件数据进行解码操作
BASE64Decoder decoder = new sun.misc.BASE64Decoder();
//BASE64Decoder decoder = new BASE64Decoder();
//通过Base64解密，将图片数据解密成字节数组
byte[] bytes = decoder.decodeBuffer(ci.getImageData());
//构造字节数组输入流
ByteArrayInputStream bais = new ByteArrayInputStream(bytes);
//读取输入流的数据
BufferedImage bi = ImageIO.read(bais);
//将数据信息写进图片文件中
ImageIO.write(bi, "jpg", f);// 不管输出什么格式图片，此处不需改动
bais.close();
// 生成缩略图
Thumbnails.of(new File(savePath + newFileName))
.size(120, 90)
.toFile(new File(savePath, thumbnail));
}
