在WebSocket中添加ssl遇到的问题

[toc] 做个记录

错误日志及解决方案

可以从复制下自己的错误,在网页中找下,看下能不能找到。

// System.setProperty("javax.net.debug", "all");

问题1:javax.net.ssl.SSLHandshakeException: No appropriate protocol

io.netty.handler.codec.DecoderException: javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate) Caused by: javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate) io.netty.handler.codec.DecoderException: javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate)

方案:权限问题

过一阵瞎搞,最后才发现是因为jdk1.8版本导致SSL调用权限上有问题。 解决办法:找到jdk 1.8安装目录,找到jdk里面的lib\security 下面有个java.security。找到对应的SSLv3,删除掉,重启项目就好了。(删掉SSLv3就是允许SSL调用)

问题2:protocol_version、 ERR_CERT_COMMON_NAME_INVALID、 ERR_CERT_AUTHORITY_INVALID

Caused by: javax.net.ssl.SSLException: Received fatal alert: protocol_version io.netty.handler.codec.DecoderException: javax.net.ssl.SSLException: Received fatal alert: protocol_version Caused by: javax.net.ssl.SSLException: Received fatal alert: protocol_version

方案:网页客户端需要信任证书

internal_error

问题3:io.netty.handler.ssl.NotSslRecordException: not an SSL/TLS record:

io.netty.handler.ssl.NotSslRecordException: not an SSL/TLS record:

方案:

客户端中pipeline.addLast("ssl", new SslHandler(sslEngine));

问题4:PKIX path building failed、General SSLEngine problem、unable to find valid certification path to requested target

方案:

  • 自己生成的证书,没有经过验证,jdk不认可
    • 启动服务器
    • 使用SSLCre请求生成一个jssecacerts
    • 将jssecacerts替换成D:\Program Files\Java\jdk1.8.0_171\jre\lib\security下的cacerts
    • 要记得改名字
