关于java+selenium启动报错问题，求大神指导

rongxiah

package com.selenium.base;
import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.*;

public class fist {
  
   private static String url="http://www.baidu.com/";
  
   public static void main(String args[]){
     
           System.setProperty("webdriver.chrome.driver", "D:\\chromedriver\\chromedriver.exe");
           WebDriver driver = new ChromeDriver();   
    driver.get(url);
    String targeturl=driver.getCurrentUrl();
    System.out.println(targeturl);
    //String pagesource = driver.getPageSource();
    //System.out.println(pagesource);
    driver.manage().window().maximize();
    driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
   
    WebElement element = driver.findElement(By.xpath(".//*[@id='su']"));   

eclipse运行后报错，可是xpath的路径根本就不是我程序中配置的，是从哪里读取的？

driver.findElement(By.xpath(".//*[@id='su']")) 改成
driver.findElement(By.xpath("//*[@id='su']"));

可以使用ID去定位啊，不一定所有的元素都要使用xpath去定位，如果有ID，name等属性的时候可以考虑直接用这些定位。
