使用相同版本的JVM,它在OSX上成功握手,在TLSv1.2
上失败,失败的原因是它只尝试使用TLSv1.2
(JVM 8中的默认值)并且不尝试使用较低的协议
调试说明:
-Ddeployment.security.TLSv1.0=true
-Ddeployment.security.TLSv1=true
-Ddeployment.security.TLSv1.1=false
-Ddeployment.security.TLSv1.2=false
-Djavax.net.debug=ssl:handshake:verbose
题:
为什么它能够在OSX上而不是在CentOS上选择TLSv1
?
如何告诉JVM按特定顺序使用协议,或者如果它按版本考虑顺序,那么我怎么能告诉它也尝试使用v1
编辑:
我有无限强度JCE策略与JRE一起安装,导致这种情况,它没有这个,所以OSX和CentOS差异消失了,我怎么能让它工作?

尝试使用以下方法将协议限制为TLSv1
:
-Djdk.tls.client.protocols=TLSv1
