DefaultSelenium过期了,那用什么代替呢？如图

The Selenium Interface and DefaultSelenium Class both belong to Selenium 1 and are deprecated. Selenium has advanced to Selenium 2 (WebDriver) and for this reason these warning messages are displayed to encourage users to stop using old Selenium 1 code and start using Selenium 2 (WebDriver) code.

To add: This has got nothing to do with your IDE (Eclipse) or your Java version.

You will want to use the following classes as these are part of Selenium 2 (WebDriver). WebDriver is an interface used by various Selenium 2 drivers.

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
Then you have various drivers that you can use. RemoteWebDriver / HtmlUnitDriver / FireFoxDriver / ChromeDriver / IEDriverServer etc. You will want to import the driver in your Java class.

Selenium selenium = new DefaultSelenium();
Becomes

WebDriver driver = new TheSpecificDriver();
