Question

请帮助解决以下问题。

我正在使用Eclipse.My主类调用下面的类/ java文件。

1）Invoke_SoapUI_Project.java（这会执行SOAP UI项目） 2）Run_Selenium_Script.java（这会打开Firefox中的一个URL）。

我的main函数调用上面的Invoke_SoapUI_Project.java并触发“SOAP UI XML Project”的执行，运行良好。

然后我的第二个函数“Run_Selenium_Script.java”调用并尝试打开网页。但在我定义webdriver对象的行处得到以下错误。即driver= new firefoxDriver();

但是，如果我评论Invoke_SoapUI_Project.java，那么我将不会得到异常，firefox对象正确创建并打开我的URL。

我得到以下异常：

我们偶然发现了同样的问题（花了我们很长时间），但我们设法解决了这个问题：

问题似乎是SoapUI将默认的proxyselector设置为null，而Apache httpclient并不期望这样。

重现问题：

WsdlProject wsdlProject = new WsdlProject("");
WebDriver driver = new FirefoxDriver();

解决方法：

ProxySelector proxy = ProxySelector.getDefault();
WsdlProject wsdlProject = new WsdlProject("");
ProxySelector.setDefault(proxy);
WebDriver driver = new FirefoxDriver();

两天前，peidong-hu发送了一个独立补丁（从那里拿出解决方案）： https://github.com/Ardesco/selenium-standalone-server-plugin/issues/23

我已经为selenium提交了错误报告，会使用以下详细信息对其进行更新：https://github.com/SeleniumHQ/selenium/issues/388

我也要为SoapUI提交一份报告。

根据link

您需要设置firefox驱动程序并将其作为系统属性提供。例如： System.setProperty("webdriver.firefox.driver", "c:/webdriver/firefoxdriverpath");

我在使用SoapUI 5时也发现了这个问题。我检查了源代码。在课程ProxyUtils中，如果您未设置代理或将代理设置为自动，则setGlobalProxy()方法会将proxySelector设置为空。

 public static void setGlobalProxy( Settings settings )
    {
    ProxySelector proxySelector = null;
    ProxySettingsAuthenticator authenticator = null;
    if( proxyEnabled )
    {
        if( autoProxy )
        {
        proxySelector = new ProxyVoleUtil().createAutoProxySearch().getProxySelector();
        }
        else
        {
            proxySelector = getManualProxySelector( settings );
        }
        if( proxySelector != null )
        {
            // Don't register any proxies for other schemes
            proxySelector = filterHttpHttpsProxy( proxySelector );
        }
        authenticator = new ProxySettingsAuthenticator();
    }
    *ProxySelector.setDefault( proxySelector );*
    Authenticator.setDefault( authenticator );
    HttpClientSupport.setProxySelector( proxySelector );
    HttpClientSupport.getHttpClient().setCredentialsProvider( getProxyCredentials( settings ) );
    }

在Windows操作系统中，proxySelector = new ProxyVoleUtil().createAutoProxySearch().getProxySelector();也将为空。

 if (PlatformUtil.getCurrentPlattform() != PlatformUtil.Platform.WIN) {
            proxySearch.addStrategy(ProxySearch.Strategy.BROWSER);
            // For Windows both BROWSER and OS_DEFAULT will end up with an IEProxySearchStrategy.
            // The call in createPacSelector to winHttpDetectAutoProxyConfigUrl is quite slow and we don't want to do it twice.
        }

我的解决方案是修改ProxyUtils类。将ProxySelector.setDefault( proxySelector );更改为

    if(proxySelector != null){
        ProxySelector.setDefault(proxySelector);
    }
    else{
        proxySelector = ProxySelector.getDefault();
    }

然后我使用自己的ProxyUtils.class，通过WinRAR或7Z更新ProxyUtils.class（soapui-xxx.jar）中的SOAPUI_HOME\bin\。现在我的SoapUI工作得非常好。
