本專案使用的環境：

• 開發工具：myeclipse
• springboot: 1.5.6
• jdk：1.7
• maven:3.3.9  

1.使用myeclipse建立一個maven專案。

ps：選擇jar java project，選擇war 為 web project

點選finish結束。如圖：

2.整合spring boot

將app放到com.guo下

package com.guo;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@MapperScan("com.guo.dao")//將專案中對應的mapper類的路徑加進來就可以了
public class App {
    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }
}
 

application.yml檔案放置：src/main/resoures下

  port: 8080
