在"慢调用比例"的降级规则配置下，抛出的DegradeException被 限流的方法捕获，而非降级

public class SentinelExceptionHandler { public static Response handleBlock(Map<String, Object> params, BlockException e){ log.error("SentinelExceptionHandler HandleBlock",e); //在不是抛出异常的情况下（rt时间长），导致抛出的DegradeException被 限流的方法捕获 if(e instanceof DegradeException){ return Response.error(ResultCode.FALLBACK_ERROR,ExceptionUtils.getStackTrace(e)); }else{ return Response.error(ResultCode.LIMIT_ERROR,ExceptionUtils.getStackTrace(e)); } }

public static Response handleFallback(Map<String, Object> params,Throwable e){
    log.error("SentinelExceptionHandler handleFallback",e);
    return Response.error(ResultCode.FALLBACK_ERROR, ExceptionUtils.getStackTrace(e));
}

暂时这样解决的，不知道是不是bug，有谁遇到相同的问题吗？

spring-cloud-starter-alibaba-sentinel ,2.2.3-RELEASE sentinel-core, 1.8.0

@SentinelResource(value = "demo-list",blockHandlerClass= SentinelExceptionHandler.class,fallbackClass = SentinelExceptionHandler.class, blockHandler = "handleBlock",fallback = "handleFallback") public Response list(@RequestParam Map<String, Object> params){ log.info("demo/demo/list invoke ------------------------------"); PageResult pageResult = demoService.queryPage(params); return Response.success(pageResult); }

@Slf4j public class SentinelExceptionHandler { public static Response handleBlock(Map<String, Object> params, BlockException e){ log.error("SentinelExceptionHandler HandleBlock",e); //在不是抛出异常的情况下（rt时间长），抛出的DegradeException被 限流的方法捕获 //todo https://github.com/alibaba/Sentinel/issues/1801 if(e instanceof DegradeException){ return Response.error(ResultCode.FALLBACK_ERROR,ExceptionUtils.getStackTrace(e)); }else{ return Response.error(ResultCode.LIMIT_ERROR,ExceptionUtils.getStackTrace(e)); } }

public static Response handleFallback(Map<String, Object> params,Throwable e){
    log.error("SentinelExceptionHandler handleFallback",e);
    return Response.error(ResultCode.FALLBACK_ERROR, ExceptionUtils.getStackTrace(e));
}

}
