jdk1.7访问https报javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure问题解决
错误日志：
本地jdk版本java version "1.8.0_31",代码中已对https做了相应处理：信任所有来源证书，运行正常；上包到服务器（服务器jdk版本java version "1.7.0_80"），报以下ssl异常：
org.htmlparser.util.ParserException: Received fatal alert: protocol_version;

1. 如果代码还可以改动（代码未上线）,直接在网络请求前加上
System.setProperty("https.protocols", "TLSv1.2,TLSv1.1,SSLv3");
2.如果代码已上线，可以设置JVM参数如下，以提高客户端的TLS版本
-Dhttps.protocols=TLSv1.2,TLSv1.1,TLSv1.0,SSLv3,SSLv2Hello
已上两种解决方案对我无效，我采用的是第三种
3. 更换jdk中jce的jar包
网上资料说这个应该是旧版本jdkjce中安全机制的bug，要去oracle官网下载对应的jce包替换jdk中的jce包
jce所在jdk的路径： %JAVA_HOME%\jre\lib\security里的local_policy.jar,US_export_policy.jarJDK7 http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.htmlJDK8 http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html
4.升级 JDK到1.8版本
