如何解决NoClassDefFoundError：SELEnium中的org / apache / http / httpEntity for ChromeDriver吗？？

开发过程中遇到NoClassDefFoundError：SELEnium中的org / apache / http / httpEntity for ChromeDriver吗？的问题如何解决？下面主要结合日常开发的经验，给出你关于NoClassDefFoundError：SELEnium中的org / apache / http / httpEntity for ChromeDriver吗？的解决方法建议，希望对你解决NoClassDefFoundError：SELEnium中的org / apache / http / httpEntity for ChromeDriver吗？有所启发或帮助；

为了检查您的代码，我尝试了以下操作：

@H_607_4@

@Test
public voID test1() throws Exception {
    System.setProperty("webdriver.Chrome.driver", "t:\\Others\\chromedriver.exe");
    WebDriver driver = new ChromeDriver();

    String url = "http://www.upmandiparishad.in/commodityWiseAll.aspx";

    driver.get(url);
    Thread.sleep(5000);

    new SELEct(driver.findElement(By.ID("ctl00_ContentPlaceHolder1_ddl_commodity"))).SELEctByVisibleText("Paddy");
    Thread.sleep(5000);

    driver.findElement(By.ID("ctl00_ContentPlaceHolder1_txt_rate")).sendKeys("27/03/2014");
    Thread.sleep(5000);

    driver.findElement(By.ID("ctl00_ContentPlaceHolder1_btn_show")).click();
    Thread.sleep(5000);

    driver.close();

}

它可以与firefox（29.0）和Chrome（34.0）驱动程序正常工作。我使用了以下jar-s：

SELE

您应该检查项目的构建路径并添加适当的jar。但是，如果打开它，则可以在SELEnium-server- standalone-2.XY.0.jar中找到丢失的类文件：SELEnium-server-standalone-2.41.0.jar \ org \ apache \ http \ entity \ ContentType

另一种方法是使用包含缺少的类文件的httpcore.jar（httpcore-4.3.jar）。

解决方法

当我尝试从该网站访问数据时，我尝试使用SELEnium自动化从网站中获取数据
