a thrift pool
- 指定多个服务地址
- 负载均衡
- 自动检测后段存活
- 如果服务离线，自动检测如果恢复那么自动上线
- 如果服务故障，自动剔除
- 连接池配置
- 使用javassist字节码生成实现iface类，性能比反射调用高。且iface的实现是多线程安全、只需要单例
ThriftConnectionPool pool = new ThriftConnectionPool(
ThriftConnectionPool.config);
final Iface face = SimpleClientProxyFactory.
makeClientFramedTransport(SegService.Iface.class, new SegService.Client.Factory(),
"127.0.0.1:9091,127.0.0.1:9090", pool, new TBinaryProtocol.Factory());
face.dosomeing();
face.dosomeing2();
