camelContext错误：INFO：`没有可用于NTLM的凭据<any realm =“”> @ myProxyHostUrl.com:8080`

Question

我想通过驼峰在http://anyPublicWebsite.url.com拨打其他API。此连接需要通过网络配置代理主机。我已经按如下方式配置了camelContext：

public class CamelTester {
    static {
        camelContext = new DefaultCamelContext();
        camelContext.getProperties().put("http.proxyAuthMethod", "Basic");
        camelContext.getProperties().put("http.proxyAuthUsername", "usernameForproxy");
        camelContext.getProperties().put("http.proxyAuthPassword", "passwordforProxy");
        camelContext.getProperties().put("http.proxyHost", "myProxyHostUrl.com");
        camelContext.getProperties().put("http.proxyPort", "8080");
        try {
            camelContext.addRoutes(new SpringRouteBuilder() {
                @Override
                public void configure() throws Exception {
                    from("direct:starthttp").to("http://anyPublicWebsite.url.com").end();
                }
            });
            camelContext.start();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

然后通过

访问它

camelContext.createProducerTemplate().sendBody("direct:starthttp", ExchangePattern.InOut,"");

启动此程序时，发生了下面提到的错误

Aug 23, 2017 4:50:38 PM org.apache.commons.httpclient.auth.AuthChallengeProcessor selectAuthScheme
INFO: ntlm authentication scheme selected
Aug 23, 2017 4:50:38 PM org.apache.commons.httpclient.HttpMethodDirector processProxyAuthChallenge
INFO: No credentials available for NTLM <any realm>@myProxyHostUrl.com:8080

我想知道为什么camel无法捕获为proxyAuth提供的用户名和密码？

*注意：这些代理设置适用于其他地方，如cmd，eclipse IDE，maven设置等。
