本文主要記錄如果解決weblogic使用URL.openConnection出現javax.net.ssl.SSLKeyException: [Security:090504]Certificate chain received from：xxx.com。。。。。。。的異常，tomcat下一切正常。

在解決問題之前查看了http://blog.csdn.net/arvinrong/article/details/7715334和http://winters1224.blog.51cto.com/3021203/1313111這兩篇文章的建議（感謝兩位作者），原因這兩位分析的很清晰了，最終採用一種簡單的方式（無須修改weblogic代理配置），如下：

URL url = new URL(null,urlStr,new sun.net.www.protocol.https.Handler());//重點在這裡，需要使用帶有URLStreamHandler引數的URL構造方法
HttpsURLConnection httpConnection = (HttpsURLConnection) url.openConnection();//由於我呼叫的是官方給微信API介面，所以採用HTTPS連線
int responseCode = httpConnection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
	InputStream urlStream = httpConnection.getInputStream();
	BufferedReader bufferedReader = new BufferedReader(
			new InputStreamReader(urlStream));
	String lineStr = "";
	while ((lineStr = bufferedReader.readLine()) != null) {
		......
	}
	.....
}
