InternetExplorerDriver 在不指定任何参数的情况下，启动监听端口会随机变化。如果需要保证其端口固定不变，可通过InternetExplorerDriverService 达到目的。示例代码：
public class testInternetExplorerService{
public static void main(String[] args){
System.setProperty("webdriver.ie.driver", "D:\Driver\IEDriverServer_Win32_2.37.0_latest\IEDriverServer.exe");
InternetExplorerDriverService.Builder builder = new InternetExplorerDriverService.Builder();
InternetExplorerDriverService internetExplorerService = builder.usingPort(5678).withHost("127.0.0.1").build();
DesiredCapabilities capab = DesiredCapabilities.internetExplorer();
capab.setCapability(InternetExplorerDriver.IE_ENSURE_CLEAN_SESSION, true);
capab.setCapability(InternetExplorerDriver.INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS, true);
WebDriver driver = new InternetExplorerDriver(internetExplorerService, capab);
driver.get("http://www.baidu.com");
}
}
