zooland 新開源的RPC項目，希望大家在開發的微服務的時候多一種選擇，讓微服務開發簡單，并且容易上手。...

zooland 我叫它動物園地，一個構思很長時間的一個項目。起初只是覺得各種通信框架都封裝的很好了，但是就是差些兼容，防錯，高可用。同時在使用上，不希望有多余的代碼，像普通接口一樣使用就可以了。

基于這些想法，看了很多資料，有了很多啟發；也開發出這樣一個版本，而且也在實際項目中應用起來了，算是小有成就吧。但同時深知一個人的力量有限，希望得到整個社區幫助。幫助我完善它，讓它成為.net 平臺下一個不錯的選擇。

首先，介紹一下這個項目。

項目中沒有實現自己的通信層代碼，因為大廠為我們提供了比如 thrift、grpc、HTTP、wcf、akka.net、netty.net 等等。

其次既然我都支持了這么多種通信框架了，那么他們在同一個項目中進行混用也是可以的。比如你的.net 項目內使用wcf 或 netty通信，這個時候elk或者搜索引擎為你提供了thrift的接口，那么用這個框架會是不錯的選擇。

項目中主要的精力放在了LoadBalace、調用錯誤隔離、重試、緩存，多種形式的Cluster、以及如何以最簡單的方式讓隊員通過直鏈的方式進行開發。

服務注冊和發現，現在還沒有很好的實現想法，希望社區能幫忙，當然有接口性能監控的能手，和調用鏈或熟悉dapper的能加入我，那么我會更高興。

ioc上無賴選擇了Spring.net，希望spring.net 早點出.net core版本的，這樣我會很省心的去開發.net core 版的zooland;

autofac 我正在嘗試，希望能作為spring.net 的替代版本，可能是因為習慣了spring.net 感覺autofac我增加我的配置文檔的數量，這是我不喜歡的

ioc 我也不喜歡對框架內部侵入太多的，它會讓我覺得我的架構很臃腫，讓我覺得ioc 不過是虛擬工廠來生產真正的實例，而且還要讓我到處引用虛擬工廠的類庫，想想都覺得煩。

計劃還是有的：

準備在框架層加入過濾器，這樣CAS 做分布式事務的開源框架也能整合進來，緩存也能獨立成一個Filter 的實現

比較麻煩的是調用鏈，需要埋點，由于支持了多種通信框架，而基于dapper論文的追蹤訪問鏈條的方式，可能導致有些通信框架不支持，比較麻煩，一直在想，tcp/ip協議是不是也有想http一樣的，可以在訪問header里面添加調用鏈的內容。也希望社區有好的辦法。當然能推動大廠們提供的通信框架的改進，那就更好了。

有代碼有真相，下面是用于調用的代碼，對使用來說絕對easy
