我正在运行RabbitMQ 3.6.1 / Erlang 18.3，并发现我无法使用Spring AMQP 1.5.4.RELEASE Java客户端与代理建立TLSv1或TLSv1.1会话。但是，我能够与代理建立TLSv1.2会话。我的RabbitMQ代理配置为支持tlsv1，tlsv1.1和tlsv1.2中的所有三个。我在OS X上使用Java 1.8.0_77-b03。
这是我的RabbitMQ配置：
https://gist.github.com/ae6rt/de06d1efecf62fbe8cef31774d9be3d7
代理上的Erlang报告ssl版本
# erl
Eshell V7.3 (abort with ^G)

[{ssl_app,"7.3"},
{supported,['tlsv1.2','tlsv1.1',tlsv1]},
{available,['tlsv1.2','tlsv1.1',tlsv1,sslv3]}]
这是RabbitMQ在失败时记录的错误：
=ERROR REPORT==== 22-Apr-2016::03:19:02 ===
SSL: hello: tls_handshake.erl:167:Fatal error: insufficient security
在TLS设置期间，我使用tcpdump来嗅探安全端口5671上的流量。这是tshark对该数据的格式化：

我的RabbitMQ代理配置为协商tlsv1，tlsv1.1和tlsv1.2。为什么在代理应支持tlsv1和tlsv1.1时TLS设置失败？相同的Java客户端可以与RabbitMQ 3.3.1 / Erlang R16B02代理协商TLSv1。
谢谢。
答案 0 :(得分：1)
18.3.x系列中的Erlang ssl应用程序中存在一些回归。其中一个导致您所看到的内容：客户端在握手期间拒绝，服务器端登录insufficient security。如果我没记错的话，这出现在补丁18.3.3中，并在18.3.4中修复。这不是客户的问题。
在18.3.2中有一个回归，修正在18.3.3中，这阻止了RabbitMQ的启动（由于密码套件的表示发生了变化）。
因此建议保持18.3（初始版本）或更新到19.x。
