创建bean
@Component
public class SnowflakeHelper {
@Value("${uniqueWorkerId}")
private Short uniqueWorkerId;
@PostConstruct
public void init() {
IdGeneratorOptions options = new IdGeneratorOptions(uniqueWorkerId);
YitIdHelper.setIdGenerator(options);
}
public Long nextId() {
return YitIdHelper.nextId();
}
}
在controller上加上雪花id
@RestController
public class SnowflakeController {
@Autowired
SnowflakeHelper snowflakeHelper;
@RequestMapping("/test")
public String Test() {
Long nextId = snowflakeHelper.nextId();
System.out.println(nextId);
return "ok";
}
}
