（一）搭建基础框架(Springboot+SSM)

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>
    <!-- 继承spring-boot父包 -->
    <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>
        <!--mysql驱动-->
        <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>
            <!-- 表示开发的时候引入，发布的时候不会加载此包 -->
             <scope>test</scope>
        </dependency>
    </dependencies>
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
        <!-- 配置java版本 不配置的话默认父类配置的是1.6-->
        <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;
