在上一篇博客中，我們通過Storm.Net.Adapter創建了一個使用Csharp編寫的Storm Topology - wordcount。本文將介紹如何編寫Java端的程序以及如何發布到測試的Storm環境中運行。
如果你覺得對你有幫助，歡迎Star和Fork，讓更多人看到來幫助完善這個項目。
STEP1: 克隆storm官方示例項目 storm-starter：
$ git clone git://github.com/apache/storm.git && cd storm/examples/storm-starter
STEP2: 增加csharp的多語言支持：
將上一篇博客 使用Csharp創建你的第一個Storm拓撲 中完成的項目編譯，把生產的組件拷貝到 /multilang/resources/ 文件夾中。
STEP3：使用JAVA創建Topology：
在 /src/jvm/storm/starter/ 新增 WordCountTopologyCsharp.java
