    Proxy proxy = new Proxy();  
    //设置代理服务器地址  
    proxy.setHttpProxy("代理服务器地址:端口号");  
    DesiredCapabilities capabilities = DesiredCapabilities.htmlUnit();  
    capabilities.setCapability(CapabilityType.PROXY, proxy);  
    WebDriver driver = new HtmlUnitDriver(capabilities)  
    {  
        @Override  
        protected WebClient modifyWebClient(WebClient client)  
        {  
            DefaultCredentialsProvider creds = new DefaultCredentialsProvider();  
            creds.addCredentials("用户名", "密码");  
            client.setCredentialsProvider(creds);  
            return client;  
        }  
    };  
    driver.get("http://www.baidu.com");  
    System.out.println("[" + driver.getTitle() + "]");
