首先创建一个maven项目，添加pom依赖包如下：  
pom.xml

<?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
        <modelVersion>4.0.0</modelVersion>
    
        <groupId>per.san</groupId>
        <artifactId>jee-love</artifactId>
        <version>1.0-SNAPSHOT</version>
    
        
        <parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>2.1.1.RELEASE</version>
            <relativePath></relativePath>
        </parent>
    
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
    
            <dependency>
                <groupId>tk.mybatis</groupId>
                <artifactId>mapper-spring-boot-starter</artifactId>
                <version>2.0.0</version>
            </dependency>
    
            
            <dependency>
                <groupId>mysql</groupId>
                <artifactId>mysql-connector-java</artifactId>
                <version>5.1.36</version>
            </dependency>
    
            <dependency>
                <groupId>junit</groupId>
                <artifactId>junit</artifactId>
                <version>4.8.2</version>
                
                 <scope>test</scope>
            </dependency>
        </dependencies>
    
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
            </plugins>
    
            
            <pluginManagement>
                <plugins>
                    <plugin>
                        <artifactId>maven-compiler-plugin</artifactId>
                        <configuration>
                            <source>1.8</source>
                            <target>1.8</target>
                        </configuration>
                    </plugin>
                </plugins>
            </pluginManagement>
        </build>
    </project>

添加配置文件：  
application.yml

server:
      port: 8090
    spring:
      application:
        name: jee-love
      datasource:
        url: jdbc:mysql://127.0.0.1:3306/jee-love?useUnicode=true&characterEncoding=utf-8&useSSL=false&allowMultiQueries=yes
        username: root
        password: root
        driver-class-name: com.mysql.jdbc.Driver
    
    mybatis:
      mapper-locations: classpath*:/mapper/*/*.xml

然后开始编写demo代码测试：  
StartApplication.java

@MapperScan(basePackages = { "per.san.*.mapper","per.san.*.mapper.*"})
    @Configuration
    @EnableAutoConfiguration
    @ComponentScan
    public class StartApplication { 
        public static void main(String[] args) { 
            SpringApplication.run(StartApplication.class, args);
        }
    }

DemoController.java

@Controller
    public class DemoController { 
    
        @Autowired
        IDemoService iDemoService;
    
        @RequestMapping("/demo")
        @ResponseBody
        List<Demo> demo() { 
            return iDemoService.select();
        }
    }

DemoMapper.java

public interface DemoMapper extends BaseMapper<Demo> { 
    }

测试表

CREATE TABLE `demo` (
      `id` bigint(20) NOT NULL AUTO_INCREMENT,
      `name` varchar(255) DEFAULT NULL,
      `password` varchar(255) DEFAULT NULL,
      PRIMARY KEY (`id`)
    ) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

继承的BaseMapper包含了基本业务所需的增删该查，直接调用即可  
启动项目，访问http://localhost:8090/demo,出现如下格式数据（数据为表里自己添加的数据）即项目搭建成功：
