I have following api returning Flux of String

我有以下返回字符串通量的接口

 @GetMapping(value = "/api/getStrListFlux",produces = MediaType.TEXT_EVENT_STREAM_VALUE)
    public Flux<String> getListOfStr0() {
        return Flux.just("Str-1", "Str-2", "Str-3", "Str-4", "Str-5")
                .log().delayElements(Duration.ofSeconds(1));
    } 

Whenever I stop the Springboot Application while above method is yet to finish producing all the elements, following exception is thrown

每当我在上述方法尚未完成所有元素的生成时停止SpringBoot应用程序时，都会抛出以下异常

Could not able to find any help. Please explain what is the cause and remedy for this..

找不到任何帮助。请解释一下造成这种情况的原因和补救措施。

I expect that SpringBoot application shutdowns gracefully and there is no error while doing so.

我希望SpringBoot应用程序能够正常关闭，并且不会出现任何错误。

in order for it to shutdown gracefully u need to set this property: server.shutdown=graceful

为了让它正常关闭，您需要设置此属性：server.Shutdown=graceful
