引入依赖

<dependency>
    <groupId>cn.sexycode</groupId>
    <artifactId>myjpa-spring-boot-starter</artifactId>
    <version>0.0.4-SNAPSHOT</version>
</dependency>
<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>2.1.3</version>
</dependency>

配置数据源和mapper扫描

mybatis:
  mapper-locations: UserMapper.xml

spring:
  datasource:
    password:
      zxcf123456
    username: root
    url: jdbc:mysql://localhost:3306/jpademo?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf8&useSSL=false

@MapperScan("cn.sexycode.myjpa.samples.dao")

使用

@SpringBootApplication(scanBasePackages = "cn.sexycode.myjpa.samples")
@MapperScan("cn.sexycode.myjpa.samples.dao")
public class MyJpaSamplesApplication {
    public static void main(String[] args) {
        ConfigurableApplicationContext context = SpringApplication.run(MyJpaSamplesApplication.class);

        UserDao userDao = context.getBean(UserDao.class);
        System.out.println("user: " + userDao.findByFullName("1"));
    }
}
