我正在尝试通过代理使用camel https4组件连接到外部httpsendpoint。为此，我在linux（18.04）中设置了squid代理。
根据参考文献[http://camel.apache.org/http4.html]，我注意到这可以使用proxyAuthHost和proxyAuthPort参数来完成。所以我试着用下面给出的URL来检查它
http：//endpoint-ssl-url.com/path/to/resource?proxyAuthPort=xxxx
但是它不断地给出“javax.net. ssl.SSLException：无法识别的SSL消息，明文连接？”。我尝试了下面提到的许多方法，但结果是一样的。
有人能根据你的经验/专业知识给出一点提示吗？
尝试1：使用PoolingHttpClientConnectionManager
代码：
@ApplicationScoped
@ContextName("camel_cdi_context")
public class HTTPRouter extends RouteBuilder {
@Override
public void configure() throws Exception {
errorHandler(deadLetterChannel("direct:error"));
try {
SSLContext sslContext = new SSLContextBuilder()
.loadTrustMaterial(null, new TrustStrategy() {
public boolean isTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {
System.out.println("HTTPRouter.configure().new TrustStrategy() {...}.isTrusted()");
return true;
}
})
.build();
final SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext);
HttpComponent http4 = getContext().getComponent("https4", HttpComponent.class);
http4.setHttpClientConfigurer(new HttpClientConfigurer() {
@Override
public void configureHttpClient(HttpClientBuilder builder) {
builder.setSSLSocketFactory(sslsf);
System.out.println("HTTPRouter.configure().new HttpClientConfigurer() {...}.configureHttpClient()-1");
Registry<ConnectionSocketFactory> r = RegistryBuilder.<ConnectionSocketFactory>create()
.register("http", PlainConnectionSocketFactory.getSocketFactory())
.register("https", sslsf)
.build();
System.out.println("HTTPRouter.configure().new HttpClientConfigurer() {...}.configureHttpClient()-2");
HttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(r);
System.out.println("HTTPRouter.configure().new HttpClientConfigurer() {...}.configureHttpClient()-3");
builder.setConnectionManager(cm);
System.out.println("HTTPRouter.configure().new HttpClientConfigurer() {...}.configureHttpClient()-4");
}
});
} catch (Exception e) {
e.printStackTrace();
}
from("direct:http")
// prepare request payload
// set url to header
// set other connection properties (eg : Connection Method, Header etc)
.choice()
.when(header("url").contains("?"))
.toD("${header.url}&throwExceptionOnFailure=false")
.endChoice()
.otherwise()
.toD("${header.url}?throwExceptionOnFailure=false")
.endChoice()
.end()
.convertBodyTo(String.class)
// process on the response
}
}

尝试-8：以同样的方式尝试了另一个带有http4组件的超文本传输协议endpoint，并成功了。
尝试-9：尝试直接使用to（）组件，但结果相同。
尝试10：在系统属性的尝试中成功了。但是我一直在通过系统外属性寻找解决方案。在这里为社区发帖。所以，如果有任何进一步的发现，请留下答案/评论
将代理设置添加到syetem属性，如下所述。
System.setProperty("http.proxyHost", "192.168.xxx.xxx");
System.setProperty("http.proxyPort", "xxxx");
System.setProperty("https.proxyHost", "192.168.xxx.xxx");
System.setProperty("https.proxyPort", "xxxx");
或
-Dhttp.proxyHost=192.168.xxx.xxx -Dhttp.proxyPort=xxxx -Dhttps.proxyHost=192.168.xxx.xxx -Dhttps.proxyPort=xxxx
将useSystemProperties标志true放入URL如下。
https4://endpoint-ssl-url.com/path/to/resource?useSystemProperties=true
然后它可以正常工作，如下面的日志所述
