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);

}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，不然一章东西太多写不下。
