本文整理了Java中io.netty.handler.ssl.OpenSsl.version()方法的一些代码示例，展示了OpenSsl.version()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。OpenSsl.version()方法的具体详情如下：
包路径：io.netty.handler.ssl.OpenSsl
类名称：OpenSsl
方法名：version

OpenSsl.version介绍

[英]Returns the version of the used available OpenSSL library or -1 if #isAvailable()returns false.
[中]返回已使用的可用OpenSSL库的版本，如果#isAvailable（）返回false，则返回-1。
