Spring +SpringMVC+mybatis+dubbo idea分層專案搭建
阿新 • • 發佈：2019-01-25
前言:
這是我們常用的專案結構，一個稍微大一點的專案都會用到分散式，索性今天就把dubbo也加上，至於為什麼要用idea，應為個人喜歡這款編輯器吧。下面我們就開始。
第一步：專案結構建立
整體結構是這樣的，採用的是三層專案結構，整體pom.xml應用流程是這樣的：
ssm-domain 引入了ssm-core ； ssm-dao 引入了 ssm-domian ； ssm-redis 引入了 ssm-domian ；soa-api 引入 ssm-redis ，ssm-dao ； ssm-service 引入 ssm-aip ；soa-base 引入 soa-api ；剩下的子專案 soa-user 等其他都引入soa-base ；最後ssm-web 引入ssm-service，具體業務程式碼在ssm-soa裡面寫，soa-api定義介面，其他是具體實現。
第二部：匯入相應的jar包，maven 依賴
ssm-core ---》 pom.xml

第五步：Spring xml 配置

ssm-core -----》 base.xml

第六部：dubbo 消費者，提供者配置
因為ssm-service 只引入了 soa-api 沒有
