作用：mybatis代碼生成器，包括mapper、entity、dao、service、controller等文件。
1、安裝插件（需要重啓）
Setting - Plugins - Browse repositories
2、添加數據庫
IDEA界面右邊工具欄 - Database - +圖標
選擇mysql
填寫Host、Database、User、Password信息，並點擊Test Connection，出現Successful即可。
3、生成mapper、entity、dao、service、controller文件
3.1、選擇對應的表
3.2、右鍵 - EasyCode - Generate Code
3.3、填寫EasyCode Title Info信息
Module：你的項目
Package：你的包
Path：項目路徑
Template：你要生成的文件，例如我們把圖示的都打上勾
3.4、查看
4、添加maven依賴（按需添加）

5、修改application.properties文件
application.properties
############## Spring ##############
server.servlet.context-path=/spring-boot
server.port=8882
############## Mybatis ##############
mybatis.mapper-locations=classpath:mapper/*.xml
mybatis.type-aliases-package=com.darren.center.sprintboot.entity
#開啓下劃線到駝峯的自動轉換（將數據庫字段按照駝峯規則自動注入到對象屬性）
mybatis.configuration.map-underscore-to-camel-case=true
############## log ##############
logging.level.com.darren.center.springboot.dao=debug
############## custom config ##############
spring.profiles.active=dev
TIPS：
mybatis.mapper-locations=classpath:mapper/*.xml這個配置的生成的默認包名是mapper，配置不對報Invalid bound statement (not found): com.darren.center.springboot.dao.UserDao.queryById異常。
application-dev.properties
############## 連接池 ##############
#https://blog.csdn.net/tb_520/article/details/79676543（spring boot 2.1.0 新版配置）
#在本地使用&來進行轉義，會造成中文亂碼
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/darren_service_center?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&autoReconnectForPools=true
spring.datasource.username=root
spring.datasource.password=1234
############## redis ##############
spring.redis.host=127.0.0.1
spring.redis.port=6379
spring.redis.password=
############## 是否打印AOP日誌 ##############
isLogger=true
6、添加註解
啓動類添加@MapperScan註解，當然也可以在每個Dao上添加@Mapper註解
package com.darren.center.springboot;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
@MapperScan("com.darren.center.springboot.dao")
public class SpringbootEasyCodeApplication {
public static void main(String[] args) {
SpringApplication.run(SpringbootEasyCodeApplication.class, args);
}
}
7、啓動項目並訪問接口
