最近新入职了一家公司，果然一进去就给了一个很大的坑。模拟用户登录 XX 网站。这是要玩图像识别的节奏啊。。。吓尿了 赶紧度娘一波。

Selemium

1：引入 maven

`

    <dependency>
        <groupId>org.sele~~~~niumhq.selenium</groupId>
        <artifactId>selenium-java</artifactId>
        <version>3.141.0</version>
    </dependency>
    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-server</artifactId>
        <version>3.141.0</version>
    </dependency>
    <dependency>~~~~
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-chrome-driver</artifactId>
        <version>2.41.0</version>
    </dependency>`

2：引入 chrome 插件 chromedriver.exe

其中 chromedriver.exe 可以在网址 http://chromedriver.storage.g… 注意版本问题, 查看本地 chrom 版本并下载对应的 chromedriver.exe, 版本对应可在版本明细中的 notes.txt 页面查看

3：封装 SelemiumUtil 工具类

public class SeleniumUtil {private static final ChromeOptions chromeOptions = new ChromeOptions();

    static {System.setProperty("webdriver.chrome.driver", "src\\main\\resources\\chromedriver.exe");
        Map<String, Object> chromePrefs = CollUtil.newHashMap();
        // 禁止弹窗
        chromePrefs.put("profile.default_content_settings.popups", 0);
        // 下载地址
//        chromePrefs.put("download.default_directory", "C://xx//");
        // 禁止图片加载
//        chromePrefs.put("profile.managed_default_content_settings.images", 2);
        //userAgent=ie11
        String userAgentIE11="Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.117 Safari/537.36";
        chromePrefs.put("profile.general_useragent_override", userAgentIE11);

        HashMap<String, Object> mobileEmulation = new HashMap<String, Object>();
        // 用 iPhone X 屏幕启动
//        mobileEmulation.put("deviceName","iPhone X");

        chromeOptions.setExperimentalOption("prefs",chromePrefs);
        chromeOptions.setExperimentalOption("mobileEmulation",mobileEmulation);
        /*********************************** 以下设置启动参数 ******************************************/
        // 消除安全校验

Tess4j OCR 图像识别框架集成

1：引入 maven

`

    <dependency>
        <groupId>net.java.dev.jna</groupId>
        <artifactId>jna</artifactId>
        <version>5.1.0</version>
    </dependency>
    <dependency>
        <groupId>net.sourceforge.tess4j</groupId>
        <artifactId>tess4j</artifactId>
        <version>4.3.1</version>
        <exclusions>
            <exclusion>
                <groupId>com.sun.jna</groupId>
                <artifactId>jna</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

`

2：导入训练库

训练库下载地址：https://sourceforge.net/projects/tess4j/files/

下载完之后解压 将 tessdata 复制到 resource 目录下

3：初始化 tess4j

Opencv 集成

1：下载 opencv

下载地址：https://sourceforge.net/projects/opencvlibrary/files/4.1.1/opencv-4.1.1-vc14_vc15.exe/download
下载完是一个.exe 文件 直接安装之后会生成一个目录

将 jar 包引入项目
`

<dependency>
        <groupId>org.opencv</groupId>
        <artifactId>opencv</artifactId>
        <version>4.1.1</version>
        <scope>system</scope>
        <systemPath>${project.basedir}/lib/opencv-411.jar</systemPath>
    </dependency>`

还没完 将刚才目录下的 x64 目录下有个 opencv_java411.dll 文件，放到项目的 resource 目录下，然后在项目初始化中引入
`

    String opencvLib = System.getProperty("user.dir") + "\\src\\main\\resources\\opencv";
    addLibraryDir(opencvLib);
    System.load(opencvLib+"\\opencv_java411.dll");

`
addLibraryDir 代码也贴一下

public void addLibraryDir(String libraryPath) throws IOException {
        try {Field field = ClassLoader.class.getDeclaredField("usr_paths");
            field.setAccessible(true);
            String[] paths = (String[]) field.get(null);
            for (int i = 0; i < paths.length; i++) {if (libraryPath.equals(paths[i])) {return;}
            }

            String[] tmp = new String[paths.length + 1];
            System.arraycopy(paths, 0, tmp, 0, paths.length);
            tmp[paths.length] = libraryPath;
            field.set(null, tmp);
        } catch (IllegalAccessException e) {
            throw new IOException("Failedto get permissions to set library path");
        } catch (NoSuchFieldException e) {
            throw new IOException("Failedto get field handle to set library path");
        }
    }

好了，到这边算是初始化完成。图像识别的代码下一章贴一下，不然一张东西太多写不下。
