初始界面
项目结构
SpringBootApplication——SpringBoot启动类
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class IdCardorcApplication {
public static void main(String[] args) {
SpringApplication.run(IdCardorcApplication.class, args);
}
}
MainController——控制进程
异常情况下clear
if != backImages.size) {
faceImages.clear;
backImages.clear;
faceResults.clear;
backResults.clear;
}
刷新页面重新加载已识别结果
if (!CollectionUtils.isEmpty(faceImages) && faceImages.size() == backImages.size()) {
model.addAttribute("faceImage", faceImages.get(faceImages.size() - 1));
model.addAttribute("faceResult", faceResults.get(faceResults.size() - 1));
model.addAttribute("backImage", backImages.get(backImages.size() - 1));
model.addAttribute("backResult", backResults.get(backResults.size() - 1));
}
上传文件判定
public String upload(@RequestParam("face") MultipartFile face, @RequestParam("back") MultipartFile back,
RedirectAttributes redirectAttributes) {
if (face.isEmpty() || back.isEmpty()) {
redirectAttributes.addFlashAttribute("messages", "请选择一个文件进行上传。");
return "redirect:/index";
}
String errorMessages = null;
Path dir = Paths.get(uploadDir);
if (!Files.exists(dir)) {
try {
Files.createDirectories(dir);
} catch (IOException e) {
e.printStackTrace();
errorMessages += e.getMessage() + "\n";
}
}
try {
if (!face.isEmpty()) {
String filename = saveFile(face);
Map<String, String> faceResult = ocrService.RecognizeIdCard(uploadDir + filename, "face");
faceImages.add("/images/" + filename);
faceResults.add(faceResult);
}
if (!back.isEmpty()) {
String filename = saveFile(back);
Map<String, String> faceResult = ocrService.RecognizeIdCard(uploadDir + filename, "back");
backImages.add("/images/" + filename);
backResults.add(faceResult);
}
} catch (Exception e) {
e.printStackTrace();
errorMessages += e.getMessage() + "\n";
}
if (StringUtils.isNoneBlank(errorMessages)) {
redirectAttributes.addFlashAttribute("messages", errorMessages);
}
return "redirect:/index";
}
存储逻辑
public String saveFile(MultipartFile file) {
String filename = UUID.randomUUID().toString() + "."
+ StringUtils.substringAfterLast(file.getOriginalFilename(), ".");
Path path = Paths.get(uploadDir + filename);
System.out.println(faceResults);
try {
Files.copy(file.getInputStream(), path, StandardCopyOption.REPLACE_EXISTING);
} catch (IOException e) {
return null;
}
return filename;
}
OcrService——通过SDK调用视觉开放平台的OCR
初始化config
private void init() throws Exception {
Config config = new Config()
config.endpointType = "access_key"
config.regionId = "cn-shanghai"
config.accessKeyId = accessKeyId
config.accessKeySecret = accessKeySecret
config.endpoint = "ocr.cn-shanghai.aliyuncs.com"
orcClient = new Client(config)
runtimeOptions = new RuntimeOptions()
}
调用逻辑
public Map<String, String> RecognizeIdCard(String fielpath, String side) throws Exception {
RecognizeIdentityCardAdvanceRequest request = new RecognizeIdentityCardAdvanceRequest();
request.imageURLObject = Files.newInputStream(Paths.get(fielpath));
request.side = side;
RecognizeIdentityCardResponse response = orcClient.recognizeIdentityCardAdvance(request, runtimeOptions);
return "face".equals(side) ?
JSON.parseObject(JSON.toJSONString(response.data.frontResult), new TypeReference<Map<String, String>>(){})
: JSON.parseObject(JSON.toJSONString(response.data.backResult), new TypeReference<Map<String, String>>(){});
}
index.html——前端模板
