Activemq 使用 SSL

activeqm 使用ssl 除了配置服务端外客户端连接的时候也需要使用ssl,网上的和官方的资料都比较散，因此收集到一起做写例子，共两个部分。第一部分是配置服务端，第二部分是客户端测试连接。

http://activemq.apache.org/download.html

先到官方下载activemq 目前版本是5.2.0，

第一部分配置服务端

按官方http://activemq.apache.org/how-do-i-use-ssl.html

的4步分生成ks,和ts文件。

Also see Tomcat's SSL instructions for more info. The following was provided by Colin Kilburn. Thanks Colin!

Using keytool, create a certificate for the broker:

keytool -genkey -alias broker -keyalg RSA -keystore broker.ks

Export the broker's certificate so it can be shared with clients:

keytool -export -alias broker -keystore broker.ks -file broker_cert

Create a certificate/keystore for the client:

keytool -genkey -alias client -keyalg RSA -keystore client.ks

Create a truststore for the client, and import the broker's certificate. This establishes that the client "trusts" the broker:
```
keytool -import -alias broker -keystore client.ts -file broker_cert
```

配置activemq.xml sslContext配好生成文件的路径和密码

配置ssl端口

启动 activemq 服务端配置完毕。

第二部分是客户端测试连接。

需要服务端生成的client.ks和client.ts文件

测试发送Message。。。
