# 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 ###

*  ERR\_CERT\_COMMON\_NAME\_INVALID
 *  ERR\_CERT\_AUTHORITY\_INVALID
 *  解决方案  
    
    
    1.  chrome访问chrome://flags/\#show-cert-link
    2.  找到Allow invalid certificates for resources loaded from localhost.
    3.  改成Enabled

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
