我建立了一個簡單的多模組的專案:
結構:

能運行 打包封包IndexService 不存在
package com.example.demo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@SpringBootApplication
@Controller
public class DemoControllerApplication {
@Autowired
private IndexService indexService;
public static void main(String[] args) {
SpringApplication.run(DemoControllerApplication.class, args);
}
@RequestMapping(value = "")
@ResponseBody
public String index(){
return indexService.Index();
}
}
這不是Spring-boot的問題,這是Maven依賴的問題
假設我有一個maven工程是醬紫的
尖括號是工程類型,前面是工程層級
iot-cloud總工程下有5個子工程,其中iot-restful是入口工程,也就是Spring-boot的啟動工程,它依賴其他四個工程來提供服務,那麼你就在iot-resutful中引入其它四個作為dependency,然後maven install就好了
當然啦,測試用例不打包,設定檔引入優先順序還是要考慮的
