Spring 多次调用控制器方法

Question

我有一个 spring 引导应用程序，它充当离子应用程序的服务，每当我调用 api 时，控制器方法都会被调用两次，例如：

@RestController
@CrossOrigin
@RequestMapping("/sendSMS")
public class SendSMSController {

@Autowired
SendSMSService sendSMSService;
protected final Log logger = LogFactory.getLog(getClass());

@PostMapping(value = "/sendMessage", produces = "application/json",consumes = "application/json")
public  Map<String, Object> sendMessage(@RequestBody UserRegistration userRegistration) {   
    logger.info("Api sendMessage test");
     return sendSMSService.sendMessage(userRegistration);
}
}

当我从邮递员调用 http://localhost:8080/CEPMobileService/sendSMS/sendMessage 时，api /sendMessage 被调用两次，如日志中所示

15/10/2020 09:32:29 PM |  INFO | http-nio-8080-exec-4 | SendSMSController | Api sendMessage test
15/10/2020 09:32:29 PM |  INFO | http-nio-8080-exec-4 | SendSMSController | Api sendMessage test
15/10/2020 09:32:29 PM |  INFO | http-nio-8080-exec-4 | SendSMSServiceImpl | Phone number--> 
[0000000000, 0000000000]
15/10/2020 09:32:29 PM |  INFO | http-nio-8080-exec-4 | SendSMSServiceImpl | Phone number--> 
[0000000000, 0000000000]
15/10/2020 09:32:29 PM |  INFO | http-nio-8080-exec-4 | SendSMSServiceImpl | Message number-->In 
distress!!!
15/10/2020 09:32:29 PM |  INFO | http-nio-8080-exec-4 | SendSMSServiceImpl | Message number-->In

15/10/2020 09:32:29 PM |  INFO | http-nio-8080-exec-4 | SendSMSServiceImpl | numbers---->0000000000, 
0000000000

不只是这个 api 代码中的每个 api 都会被调用两次，这在部署在 Azure 中时也会发生。一个答案表明它可能是由于 JSONView，但它在我的系统中不可用，其他答案也无济于事，请问有什么解决方案吗？

正如 anavaraslamurep 和 Ismail 所建议的，这确实是一个记录器错误，我使用了 log4j，并且在配置附加程序时消息被记录了两次。我解决了将可加性设置为 false 的问题，这里是配置：
