SpringBoot 整合Mybatis

参考demo
https://github.com/huangzhenshi/demo-ssm

1. 在启动类指定MapperScan，避免在每个Dao上写@Mapper

@SpringBootApplication
@MapperScan("com.example.demo.ssm.dao")
public class DemoSsmApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoSsmApplication.class, args);
    }

}

2. 配置

mybatis.mapper-locations=classpath*:mapper/*.xml
mybatis.type-aliases-package=com.example.demo.ssm.entity

# show mybatis sql
logging.level.com.example.demo.ssm.mapper=debug

3. 依赖
