启动类：

Controller：

@Controller
public class LcnController {

    @Autowired
    ProducerInfoMapper producerInfoMapper;

    @Autowired
    RestTemplate restTemplate;


    @RequestMapping("/addProducer")
    @Transactional(rollbackFor = Exception.class)
    @LcnTransaction
    public @ResponseBody String addProducer(){

        JSONObject json = new JSONObject();
        String id = SnowFlake.nextId()+"";// utils 里的雪花算法
        json.put("id",id);
        System.out.println("获得Id : "+id);
        ProducerInfo producerInfo = new ProducerInfo();
        producerInfo.setId(id);
        producerInfo.setName("li");
        restTemplate.postForEntity("http://localhost:8090/addConsumer",json,String.class);
//        int i = 1/0;
        producerInfoMapper.insert(producerInfo);
        return "addProducer插入成功";
    }

}
