C#教程之zooland 新开源的RPC项目,希望大家在开发
zooland 我叫它动物园地,一个构思很长时间的一个项目。起初只是觉得各种通信框架都封装的很好了,但是就是差些兼容,防错,高可用。同时在使用上,不希望有多余的代码,像普通接口一样使用就可以了。
基于这些想法,看了很多资料,有了很多启发;也开发出这样一个版本,而且也在实际项目中应用起来了,算是小有成就吧。但同时深知一个人的力量有限,希望得到整个社区帮助。帮助我完善它,让它成为.net 平台下一个不错的选择。
首先,介绍一下这个项目。
项目中没有实现自己的通信层代码,因为大厂为我们提供了 比如 thrift、grpc、HTTP、wcf、akka.net、netty.net 等等。
其次既然我都支持了这么多种通信框架了,那么他们在同一个项目中进行混用也是可以的。比如你的.net 项目内使用wcf 或 netty通信,这个时候elk或者搜索引擎为你提供了thrift的接口,那么用这个框架会是不错的选择。
项目中 主要的精力放在了LoadBalace、调用错误隔离、重试、缓存,多种形式的Cluster、以及如何以最简单的方式让队员通过直链的方式进行开发。
服务注册和发现,现在还没有很好的实现想法,希望社区能帮忙,当然有接口性能监控的能手,和调用链或熟悉dapper的能加入我,那么我会更高兴。
ioc上无赖选择了Spring.net,希望spring.net 早点出.net core版本的,这样我会很省心的去开发.net core 版的zooland;
autofac 我正在尝试,希望能作为spring.net 的替代版本,可能是因为习惯了spring.net 感觉autofac我增加我的配置文档的数量,这是我不喜欢的
ioc 我也不喜欢对框架内部侵入太多的,它会让我觉得我的架构很臃肿,让我觉得ioc 不过是虚拟工厂来生产真正的实例,而且还要让我到处引用虚拟工厂的类库,想想都觉得烦。
计划还是有的:
准备在框架层加入过滤器,这样CAS 做分布式事务的开源框架也能整合进来,缓存也能独立成一个Filter 的实现
比较麻烦的是调用链,需要埋点,由于支持了多种通信框架,而基于dapper论文的追踪访问链条的方式,可能导致有些通信框架不支持,比较麻烦,一直在想,tcp/ip协议是不是也有想http一样的,可以在访问header里面添加调用链的内容。也希望社区有好的办法。当然能推动大厂们提供的通信框架的改进,那就更好了。
有代码有真相,下面是用于调用的代码,对使用来说绝对easy

目前只支持了spring.net ,有autofac的高手,欢迎加入
希望为一部分使用.net framework 的WCF做通信层框架,转微服务架构,作为一个不错的并且平滑的升级选择。
新技术不要怕不稳定,源码都有了,而且框架结构这么简单,大胆用,有问题了,可以联系技术支持啥。

现在还没有搞明白怎么编译好一个版本怎么弄到nuget上,而且版本管理经验也欠缺,也需要依赖社区了。
