SpringBoot整合MyBatis工程

1.创建maven工程

 2.添加相关依赖

 jar
    
        org.springframework.boot
        spring-boot-starter-parent

        2.5.2
    

    
        
        
            org.springframework.boot
            spring-boot-starter-web
        
        
        
            org.springframework.boot
            spring-boot-devtools
        

        
            org.mybatis.spring.boot
            mybatis-spring-boot-starter
            2.2.0
        

        
            mysql
            mysql-connector-java
            5.1.25
            runtime
        

        
            junit
            junit
            test
        

        
            org.projectlombok
            lombok
        
    

3.在resource中创建application.yml文件，进行配置相关信息

spring:
#  数据源的配置
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/briger?serverTimezone=Asia/Shanghai&useSSL=false
    username: root
    password: 123456
#配置mybatis
mybatis:
#  mapper xml文件的位置
  mapper-locations: classpath:mapper/*.xml
#别名包的位置
  type-aliases-package: com.xie.domain
# 配置日志级别
#logging:
  #level: trace
server:
  port: 8089
  servlet:
    context-path: /text

4.编写实体类

@Data
public class Account {
    private Integer id;
    private String name;
    private  double money;
}

5.编写Mapper

@Mapper
public interface AccountMapper {

    List findAll();
}

6.配置Mapper映射文件

在srcmainresourcesmapper路径下加入UserMapper.xml配置文件"

    
        select * from account
    

7.编写controller类

@RestController
public class AccountController {
    @Autowired
    IAccountService iAccountService;

    @RequestMapping("/account")
    public String getList(){
        return iAccountService.findAll().toString();
    }

}
