基于netty, spring,轻量的高性能分布式RPC服务框架。简单，易用，高效。
- 服务端支持多种序列化方式：fastjson，hession，kryo
- 服务端支持多种压缩方式：gzip，snappy
- 服务端可根据group进行线程隔离，支持基于spring对不同的group配置不同的业务线程池
- 支持注解配置，也支持spring xml配置
- 支持服务发现服务注册
- client端支持多种负载均衡策略和容灾策略
- client内置连接池
- 基于netty 4.x版本实现，高性能（win 8cpu单机8w+）
通过注解
@ServiceProvider暴露服务，通过@MethodProvide暴露方法默认配置，如：压缩方式，序列化方式，客户端超时时间
@ServiceProvider(serviceName = "sampleService", haStrategyType = HaStrategyType.FAIL_FAST,
loadBalanceType = LoadBalanceType.RANDOM, connectionTimeout = Constants.CONNECTION_TIMEOUT, port = 8888)
public interface SampleService {
@MethodProvider(methodName = "say")
String say(String str);
@MethodProvider(methodName = "echo", serializeType = SerializeType.fastjson, compressType = CompressType.gzip)
String echo(String msg);
}基于注解
@ServiceExport发布服务，基于注解@MethodExport发布方法，
@ServiceExport
public class SampleServiceImpl implements SampleService {
@MethodExport
@Rate(2)
@Override
public String say(String str) {
return "say " + str;
}
@Interceptor("metricInterceptor")
@MethodExport
@Override
public String echo(String msg) {
return "echo " + msg;
}

}###基于spring配置
application-client.xml
可以使用api注解暴露的默认配置，也可以通过spring为每个方法定义配置
