SpringCloud Feign session传递 forward Header ###一、hystrix配置为SEMAPHORE 模式

hystrix:  command:    default:      execution:        isolation:          strategy: SEMAPHORE          semaphore:            timeoutInMilliseconds: 3000

###二、FeignClients增加 RequestInterceptor

自定义 FeignClientsConfiguration如下

@Configurationpublic class FeignClientsConfigurationCustom {	@Bean	public RequestInterceptor headerInterceptor() {		return new RequestInterceptor() {			@Override			public void apply(RequestTemplate requestTemplate) {                HttpServletRequest request = RequestUtils.getRequest();                Enumeration
    
      headerNames = request.getHeaderNames();				if (headerNames != null) {					while (headerNames.hasMoreElements()) {						String name = headerNames.nextElement();							Enumeration
     
       values = request.getHeaders(name);							while (values.hasMoreElements()) {								String value = values.nextElement();								requestTemplate.header(name, value);							}					}				}			}		};	}
