本系列文章将介绍一个使用OCR技术批量识别护照的桌面小工具的编写过程。使用到的主要技术为java、JavaFx、pdfbox等。最终代码将上传Github和Gitee。

OCR识别护照（二）：护照识别及数据导出

需求描述

一个在国际学校做HR的朋友跟我说总是需要在OA系统或excel中录入外籍人员的护照信息，每次都需要打开pdf文件或图片对照填写，一旦遇到大批外籍员工入职或更换护照、签证信息时，工作量较大且容易出错。于是我利用业余时间给她写了一个小工具，可以批量识别护照。

新建javafx项目

在Idea中新建JavaFxApplication，取名passportScanner。

设置界面大小、图标、标题

在resources/images文件夹中添加passport.png。

idea怎么创建java项目并运行，idea如何运行java项目

在Main.java的start方法中添加以下代码。

package org.xy.passportScanner;

import javafx.scene.image.Image;
import org.xy.passportScanner.config.GlobalData;
import org.xy.passportScanner.config.Settings;
import javafx.application.Application;
import javafx.event.EventHandler;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
import javafx.stage.WindowEvent;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.yaml.snakeyaml.Yaml;
import org.yaml.snakeyaml.Constructor.Constructor;
import java.io.InputStream;

public class Main extends Application {

    private static final Logger logger = LoggerFactory.getLogger(Main.class);

    @Override
    public void start(Stage primaryStage) throws Exception {

        //加载界面文件
        Parent load = FXMLLoader.load(getClass().getClassLoader().getResource("main.fxml"));
        //设置窗口大小
        Scene scene = new Scene(load, 1024, 500);
        primaryStage.setScene(scene);
        //设置标题和logo
        primaryStage.setTitle("PassportScanner");
        primaryStage.getIcons().add(new Image("images/passport.png"));
        //显示页面
        primaryStage.show();
        //关闭事件处理
        primaryStage.setOnCloseRequest(new EventHandler<WindowEvent>() {
            @Override
            public void handle(WindowEvent event) {
                System.exit(0);
            }
        });
    }

    public static void main(String[] args) {
        launch(args);
    }
}

tableview绑定数据

新建PassportBean.java类，与不同javabean不同，所有属性均使用StringProperty，以便与javafx组件绑定数据。

package org.xy.passportScanner.data;


import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.StringProperty;

public class PassportBean {
    //文件序号
    private StringProperty id = new SimpleStringProperty();
    //文件名
    private StringProperty file = new SimpleStringProperty();
    //护照号
    private StringProperty number = new SimpleStringProperty();
    //姓名
    private StringProperty name = new SimpleStringProperty();
    //性别
    private StringProperty gender = new SimpleStringProperty();
    //出生日期
    private StringProperty birthday = new SimpleStringProperty();
    //有效期
    private StringProperty expireDate = new SimpleStringProperty();
    //签发国
    private StringProperty issuingCountry = new SimpleStringProperty();
    //国籍
    private StringProperty nationality = new SimpleStringProperty();
    //备注
    private StringProperty comments = new SimpleStringProperty();

    public PassportBean(String id, String file, String number, String name, String gender, String birthday, String expireDate, String issuingCountry, String nationality, String comments){
        this.id.set(id);
        this.file.set(file);
        this.number.set(number);
        this.name.set(name);
        this.gender.set(gender);
        this.birthday.set(birthday);
        this.expireDate.set(expireDate);
        this.issuingCountry.set(issuingCountry);
        this.nationality.set(nationality);
        this.comments.set(comments);
    }
    public PassportBean(){}

    public String getId() {
        return id.get();
    }

    public StringProperty idProperty() {
        return id;
    }

    public void setId(String id) {
        this.id.set(id);
    }

    public String getFile() {
        return file.get();
    }

    public StringProperty fileProperty() {
        return file;
    }

    public void setFile(String file) {
        this.file.set(file);
    }

    public String getNumber() {
        return number.get();
    }

    public StringProperty numberProperty() {
        return number;
    }

    public void setNumber(String number) {
        this.number.set(number);
    }

    public String getName() {
        return name.get();
    }

    public StringProperty nameProperty() {
        return name;
    }

    public void setName(String name) {
        this.name.set(name);
    }

    public String getGender() {
        return gender.get();
    }

    public StringProperty genderProperty() {
        return gender;
    }

    public void setGender(String gender) {
        this.gender.set(gender);
    }

    public String getBirthday() {
        return birthday.get();
    }

    public StringProperty birthdayProperty() {
        return birthday;
    }

    public void setBirthday(String birthday) {
        this.birthday.set(birthday);
    }

    public String getExpireDate() {
        return expireDate.get();
    }

    public StringProperty expireDateProperty() {
        return expireDate;
    }

    public void setExpireDate(String expireDate) {
        this.expireDate.set(expireDate);
    }

    public String getIssuingCountry() {
        return issuingCountry.get();
    }

    public StringProperty issuingCountryProperty() {
        return issuingCountry;
    }

    public void setIssuingCountry(String issuingCountry) {
        this.issuingCountry.set(issuingCountry);
    }

    public String getNationality() {
        return nationality.get();
    }

    public StringProperty nationalityProperty() {
        return nationality;
    }

    public void setNationality(String nationality) {
        this.nationality.set(nationality);
    }

    public String getComments() {
        return comments.get();
    }

    public StringProperty commentsProperty() {
        return comments;
    }

    public void setComments(String comments) {
        this.comments.set(comments);
    }
}

在MainController的initialize方法中为tableview绑定数据

//初始化结果表
resultTable.setItems(data);

TableColumn<PassportBean,String> id = new TableColumn<PassportBean,String>("序号");
id.prefWidthProperty().bind(resultTable.widthProperty().multiply(0.05));
id.setCellFactory(TextFieldTableCell.forTableColumn());
id.setCellValueFactory(new PropertyValueFactory<PassportBean, String>("id"));
id.getStyleClass().add("alarm-table");
resultTable.getColumns().add(id);

TableColumn<PassportBean,String> file = new TableColumn<PassportBean,String>("文件");
file.prefWidthProperty().bind(resultTable.widthProperty().multiply(0.15));
file.setCellValueFactory(new PropertyValueFactory<PassportBean,String>("file"));
file.getStyleClass().add("alarm-table");
resultTable.getColumns().add(file);

TableColumn<PassportBean,String> number = new TableColumn<PassportBean,String>("护照号");
number.prefWidthProperty().bind(resultTable.widthProperty().multiply(0.1));
number.setCellValueFactory(new PropertyValueFactory<PassportBean,String>("number"));
number.getStyleClass().add("alarm-table");
resultTable.getColumns().add(number);

TableColumn<PassportBean,String> name = new TableColumn<PassportBean,String>("姓名");
name.prefWidthProperty().bind(resultTable.widthProperty().multiply(0.25));
name.setCellValueFactory(new PropertyValueFactory<PassportBean,String>("name"));
name.getStyleClass().add("alarm-table");
resultTable.getColumns().add(name);

TableColumn<PassportBean,String> gender = new TableColumn<PassportBean,String>("性别");
gender.prefWidthProperty().bind(resultTable.widthProperty().multiply(0.05));
gender.setCellValueFactory(new PropertyValueFactory<PassportBean,String>("gender"));
gender.getStyleClass().add("alarm-table");
resultTable.getColumns().add(gender);

TableColumn<PassportBean,String> birthday = new TableColumn<PassportBean,String>("出生日期");
birthday.prefWidthProperty().bind(resultTable.widthProperty().multiply(0.1));
birthday.setCellValueFactory(new PropertyValueFactory<PassportBean,String>("birthday"));
birthday.getStyleClass().add("alarm-table");
resultTable.getColumns().add(birthday);

TableColumn<PassportBean,String> expireDate = new TableColumn<PassportBean,String>("有效期");
expireDate.prefWidthProperty().bind(resultTable.widthProperty().multiply(0.1));
expireDate.setCellValueFactory(new PropertyValueFactory<PassportBean,String>("expireDate"));
expireDate.getStyleClass().add("alarm-table");
resultTable.getColumns().add(expireDate);

TableColumn<PassportBean,String> issuingCountry = new TableColumn<PassportBean,String>("签发国");
issuingCountry.prefWidthProperty().bind(resultTable.widthProperty().multiply(0.05));
issuingCountry.setCellValueFactory(new PropertyValueFactory<PassportBean,String>("issuingCountry"));
issuingCountry.getStyleClass().add("alarm-table");
resultTable.getColumns().add(issuingCountry);

TableColumn<PassportBean,String> nationality = new TableColumn<PassportBean,String>("国籍");
nationality.prefWidthProperty().bind(resultTable.widthProperty().multiply(0.05));
nationality.setCellValueFactory(new PropertyValueFactory<PassportBean,String>("nationality"));
nationality.getStyleClass().add("alarm-table");
resultTable.getColumns().add(nationality);

TableColumn<PassportBean,String> comments = new TableColumn<PassportBean,String>("备注");
comments.prefWidthProperty().bind(resultTable.widthProperty().multiply(0.1));
comments.setCellValueFactory(new PropertyValueFactory<PassportBean,String>("comments"));
comments.getStyleClass().add("alarm-table");
resultTable.getColumns().add(comments);

//模拟数据
data.add(new PassportBean("1", "c:/123", "12345", "LI SI", "M", "20010302", "20250909", "CHN", "CHN", ""));
data.add(new PassportBean("2", "c:/123", "12345", "LI SI", "M", "20010302", "20250909", "CHN", "CHN", ""));

运行Main看看效果

至此，界面已经可以运行了。运行Main.main后，界面如下图。

javafx打包为exe程序

javafx打包使用的plugin为com.zenjava，详细配置如下：

如果需要修改默认的exe图标，则需要制作相应的ico图片，并放到指定目录下，如resources/images/passport.ico。

<plugin>
    <groupId>com.zenjava</groupId>
    <artifactId>javafx-maven-plugin</artifactId>
    <version>8.8.3</version>
    <configuration>
        <!--运行类-->
        <mainClass>org.xy.passportScanner.Main</mainClass>
        <vendor>pegasus</vendor>
        <bundleArguments>
            <!-- 指示用户是否可以选择应用程序安装目录 -->
            <installdirChooser>true</installdirChooser>
            <!--exe图标-->
            <icon>${project.basedir}/src/main/resources/images/passport.ico</icon>
        </bundleArguments>
        <allPermissions>true</allPermissions>
        <!--添加到程序列表-->
        <needMenu>true</needMenu>
        <!--桌面快捷方式-->
        <needShortcut>true</needShortcut>
    </configuration>
</plugin>

配置好以后，执行maven clean package和jfx:build-native即可将javafx程序打包生成exe文件，同时将java运行环境一起打包。
