專案重構00 Java maven專案下，整合Scala混合開發
阿新 • • 發佈：2019-02-02
作為補充我找了個Scala專案，但這不是我重構的了，旨在說明問題，沒什麼區別。
pom檔案，這個是我的專案的pom，其他依賴可以不用寫。
github 專案地址 https://github.com/jxnu-liguobin/SpringBoot-Base-System

</project>這裡有幾點注意是，如果使用Lombok外掛，自動編譯生產get/set方法，在寫Scala程式碼的時候，可能是找不到set/get，此時需要重新編譯Scala【我是隨便找個scala專案演示】
選擇restart Presentation complier 即可
最好設定一下eclipse編譯順序，先編譯Java,保證scala編譯之前已經有Java的set/get方法，這樣即使有打叉，但是執行是OK的。
增加maven配置後還是有Scala程式碼有大紅色的叉叉，就試著給專案新增Scala本地庫依賴
IDEA 類似。只是選單位置不同。
僅供參考。
