Tomcat配置SSL支持出现java.lang.IllegalArgumentException: None of the [protocols] specified are supported by the SSL engine : [[TLS]] 问题解决
一个Java的应用要配置TLS支持，按照软件的安装说明，给Tomcat的Server.xml中添加
重新启动Tomcat后，提示如下严重出错信息
严重 [main] org.apache.coyote.AbstractProtocol.init Failed to initialize end point associated with ProtocolHandler ["https-jsse-nio2-9443"]
java.lang.IllegalArgumentException: None of the [protocols] specified are supported by the SSL engine : [[TLS]]
at org.apache.tomcat.util.net
.SSLUtilBase.getEnabled(SSLUtilBase.java:90)
经过一番网上搜索和尝试，发现添加如下几行内容到端口8443的配置中，重启Tomcat后问题解决
SSLProtocol="TLSv1+TLSv1.1+TLSv1.2" ciphers="TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256" SSLCipherSuite="ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4"
