У меня есть два микросервиса, один api-gateway и logging-server, который регистрирует все важные журналы со всех микросервисов. Я использую симуляцию прокси и spring-mvc для общения в своих микросервисах. до сих пор у меня есть LoggingController на сервере регистрации, например:
@RestController
@RequestMapping("/logging/")
public class LoggingController {
private static final Logger LOG = LoggerFactory.getLogger(LoggingController.class);
@PostMapping("/trafic")
public void logRequest(
HttpServletRequest request,
HttpServletResponse response,
@RequestBody String body
)
{
// logging code here
}
и моя симуляция LoggingProxy в api-gateway:
@FeignClient(name = "logging-server")
@RibbonClient(name = "logging-server")
@RequestMapping("/logging/")
public interface LoggingProxy {
@PostMapping("/trafic")
void logRequest(
HttpServletRequest request,
HttpServletResponse response,
@RequestBody String body
);
}
и мой LoggingFilter, которыйэто фильтр безопасности Spring:
@Component
@Order(0)
public class LoggingFilter extends OncePerRequestFilter {
@Autowired
private LoggingProxy logging;
@Override
protected void doFilterInternal(
HttpServletRequest request,
HttpServletResponse response,
FilterChain filterChain
) throws ServletException, IOException
{
if (logging == null) {
WebApplicationContext webApp = WebApplicationContextUtils
.getWebApplicationContext(request.getServletContext());
logging = webApp.getBean(LoggingProxy.class);
}
// this object extends `HttpServletResponseWrapper` and just stores the body content of the response
HttpServletResponseCopier responseWrapper = new HttpServletResponseCopier(response);
filterChain.doFilter(request, responseWrapper);
// responseWrapper.getBody() gives the response body as a String
logging.logRequest(request, responseWrapper, responseWrapper.getBody());
}
}
, но когда я запускаю этот код, я получаю сообщение об ошибке Spring о том, что мой прокси имеет слишком много параметров Body:
org.springframework.beans.factory.UnsatisfiedDependencyException. Message: Error creating bean with name 'loggingFilter': Unsatisfied dependency expressed through field 'logging'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.agenda.gateway.proxies.LoggingProxy': FactoryBean threw exception on object creation; nested exception is java.lang.IllegalStateException: Method has too many Body parameters: public abstract void org.agenda.gateway.proxies.LoggingProxy.logRequest(javax.servlet.http.HttpServletRequest,javax.servlet.http.HttpServletResponse,java.lang.String)

Я ужепопытался обернуть запрос, ответ и тело в объект и отправить объект как @RequestBody в контроллере, но у меня были ошибки сериализации.
Любая помощь будет оценена. Спасибо
