超简单的SpringBoot整合mybatis

 　  1. 创建项目结构
　　2. 编写application.yml/application.properties配置文件
　　3. 启动类开启映射包扫描
　　4. 接口测试

创建项目结构    

导入依赖

　　　　　　　　<dependencies>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-jdbc</artifactId>
		</dependency>
		<dependency>
			<groupId>org.mybatis.spring.boot</groupId>
			<artifactId>mybatis-spring-boot-starter</artifactId>
			<version>1.3.2</version>

			<artifactId>spring-boot-starter-test</artifactId>
			<scope>test</scope>
		</dependency>

　　

编写application.yml/application.properties配置文件

启动类开启映射包扫描

    @SpringBootApplication
    @MapperScan({"com.cn.mybatis.zy.zymybatis.dao"})
    public class ZyMybatisApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(ZyMybatisApplication.class, args);
        }
    
    }

接口测试

 @Resource
    private UserService userService;

    @GetMapping("/info")
    public String info(Model model){
        List<User> allUsers = userService.getAllUsers();
        model.addAttribute("user",allUsers);
        allUsers.stream().forEach(a -> {
            System.out.println(a);
        });
        return "index";
    }
