TLS版本1.2.由于Tomcat使用JSSE作为基础SSL库，因此从JDK版本1.7开始应支持它.还要检查在Tomcat中启用的SSL密码套件.

TLS version 1.2 is supported by the Oracle JDK version 7, in the JSSE implementation. As Tomcat uses JSSE as underlying SSL library, it should be supported from JDK version 1.7 onwards. Also check your enabled SSL cipher suites in Tomcat.

如果您使用Apache作为代理，请检查Apache和基础OpenSSL文档.

If you are using Apache as a proxy, please check the Apache and underlying OpenSSL documentation.
