SpringBoot整合IotDB（利用Mybatis、Session两种方式）_gradle引入iotdb session

 自行创建controller,mapper,service(impl)等包


controller

@RestController
public class OrderController {
@Autowired
OrderService orderService;

@GetMapping("/test")
public void test(){
    Integer test = orderService.test();
    System.out.println(test);
}

}

mapper

@Mapper
public interface OrderMapper {
Integer test();
}

service

public interface OrderService {
Integer test ();
}

serviceImpl

@Service
public class OrderServiceImpl implements OrderService {
@Autowired
OrderMapper orderMapper;

@Override
public Integer test() {
    return orderMapper.test();
}

}

mappers下的映射文件 记得修改语句喔

<?xml version="1.0" encoding="UTF-8"?> select count(*) from root.ln.wf01.wt01 ```

大致结构如下

接下来运行访问即可得到结果

方案二：使用IotSession

注意：使用此方法就先把mybatis的依赖注释掉不然没有注入数据库会报错
