我试图在Java中使用phantomjsdriver来构建Webspider。我正在使用Selenium版本3.11.0，PhantomJS 2.1.1和phantomjsdriver版本1.2.1。
当我执行代码时，出现以下错误消息。
线程“主”中的异常java.lang.NoSuchMethodError：org.openqa.selenium.os.CommandLine.find（Ljava / lang / String;）Ljava / lang / String;
package Masterarbeit.Crawler;
import java.io.File;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.phantomjs.PhantomJSDriver;
public class Test {
public String Test(){
File path=new File("/usr/local/bin/phantomjs");
System.setProperty("phantomjs.binary.path",path.getAbsolutePath());
WebDriver driver = new PhantomJSDriver();
return "successful";
}
}
我的操作系统是Linux Mint 18 Sarah，有人知道原因吗？
最佳答案
直到几天前，PhantomJSDriver与selenium-server-standalone-v.v.v.jar捆绑在一起发布，因此我们能够从selenium-server-standalone-x.y.z.jar中解析PhantomJSDriver()到import org.openqa.selenium.phantomjs.PhantomJSDriver;的方法。
但是现在，selenium-server-standalone-v.v.v.jar不再捆绑PhantomJSDriver依赖的jar了。因此，您必须从（com.codeborne:phantomjsdriver:jar:1.4.4）获得phantomjsdriver的版本，该版本似乎与最新的Selenium版本保持最新。
下载并将phantomjsdriver-1.4.4.jar添加到您的项目中。
使用以下代码块并执行您的@Test：
import java.io.File;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.phantomjs.PhantomJSDriver;
public class phantomJS_launch {
public static void main(String[] args) {
File path=new File("C:\\Utility\\phantomjs-2.1.1-windows\\bin\\phantomjs.exe");
System.setProperty("phantomjs.binary.path",path.getAbsolutePath());
WebDriver driver= new PhantomJSDriver();
driver.get("https://www.google.co.in");
System.out.println(driver.getTitle());
driver.quit();
}
}
重要提示：
PhantomJSDriver()仍通过import org.openqa.selenium.phantomjs.PhantomJSDriver;解析控制台输出：
