Springboot 配置mybatis

本人使用maven创建的项目:

首先添加依赖:

<dependency>    <groupId>org.mybatis.spring.boot</groupId>    <artifactId>mybatis-spring-boot-starter</artifactId>    <version>1.3.1</version></dependency>

然后创建一个实体类:

package cn.et.lesson02.entity;public class Food {private int foodid;private String foodname;private int price;private String imgpath;public int getFoodid() {return foodid;}public void setFoodid(int foodid) {this.foodid = foodid;}public String getFoodname() {return foodname;}public void setFoodname(String foodname) {this.foodname = foodname;}public int getPrice() {return price;}public void setPrice(int price) {this.price = price;}public String getImgpath() {return imgpath;}public void setImgpath(String imgpath) {this.imgpath = imgpath;}}

然后创建Controller层:

package cn.et.lesson02.controller;import java.util.List;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;import cn.et.lesson02.entity.Food;import cn.et.lesson02.mapper.FoodMapper;@RestControllerpublic class SbController {  @Autowired FoodMapper fm ; /**  * 使用springmvc的例子  * @return  */  @RequestMapping("/queryAll") public List<Food> queryAll(){ return fm.queryFood(); }}

最后创建 主方法 和 访问主方法:

package cn.et.lesson02;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;//必须添加SpringBootApplication 启用spring的自动配置功能@SpringBootApplicationpublic class Main {/** * just run springboot启动的方法 */public static void main(String[] args) {//启动会加载自动配置  SpringApplication.run(Main.class, args);} }
