# my-rpc 2 | >了解RPC的一些原理后，尝试自己造个轮子，加深了解。 3 | 如果你对RPC的原理和运行机制还不够了解，我更希望你从最简单的版本开始了解。 4 | [https://github.com/yuyufeng1994/my-rpc/tree/v1](https://github.com/yuyufeng1994/my-rpc/tree/v1) 5 | 6 | 个人对rpc原理的见解 7 | --- 8 | >rpc是一种远程过程调用协议。rpc主要功能：异构分布式项目之间的通信，使消费者只需要知道接口，远程调用方法就像调用本地方法一样。 9 | 要使得消费层只通过接口调用远程实现方法，那么其之间的传输数据肯定是：类、方法、参数、返回值，以及一些其它传输的信息。 10 | 之间涉及到通信，肯定要发布服务供客户端请求。客户端要执行未知实现的方法，是通过动态代理实现的。 11 | 在了解动态代理的使用后，就会发现，在动态代理的方法执行过程中，可以不用去执行真实方法（invoke方法中），你可以获取到上面所需要的类、方法、参数、返回值等执行方法的参数。 12 | 那么把这些参数传输到远程去。在提供层接收到消费层方法的传参后，通过反射执行已经注册的类方法。（提供层要把暴露接口的实现类的方法注册到容器中，供查找） 13 | 自己编写rpc之前的所需的准备 14 | -- 15 | >了解了常用rpc框架dubbo的流程。复习了动态代理。复习了java io通信。 16 | 17 | 模块说明 18 | ------ 19 | #### rpc-core 20

30 | >rpc-consumer、rpc-provider为rpc使用方，所以他们两个都依赖 rpc-core 模块。 31 | 因为提供层要为消费层暴露接口，所以提取了公共接口，因此，它们两个都依赖rpc-service 32 | 33 | 34 | 启动调试 35 | -- 36 | * 使用HelloService接口进行调试。首先运行zookeeper服务，默认本地ip。 37 | *
