Description

  • I have searched the release notes of this repository and believe that this is not a duplicate.

Describe the feature

org.apache.dubbo.remoting.transport.netty4.ExtNettyConnectionClient#initBootstrap org.apache.dubbo.remoting.transport.netty4.NettyClient#initBootstrap SslContext均在ChannelInitializer外部构建初始化, 在开启MTls认证时, 客户端证书可能因为轮换或者禁用发生变更, 此时重新建连 是无法使用最新的证书进行认证的. 建议将SslContext sslContext = SslContexts.buildClientSslContext(getUrl()); 迁移到ChannelInitializer内部.

Contributor guide

Research direction
Locate the initBootstrap methods in NettyClient and ExtNettyConnectionClient, and move the SSL context building logic into the ChannelInitializer to allow per connection SSL context creation on reconnect.
