DataBufferLimitException:超出了最大限制以缓冲webflux错误 [英] DataBufferLimitException: Exceeded limit on max bytes to buffer webflux error

问题描述

在发送文件时，我收到一个字节数组.我总是对webflux接收数组有问题.引发的错误如下:

While sending a file I receive an array of bytes. I always have a problem with webflux to receive an array. the error thrown as below :

org.springframework.core.io.buffer.DataBufferLimitException: Exceeded limit on max bytes to buffer : 262144
    at org.springframework.core.io.buffer.LimitedDataBufferList.raiseLimitException(LimitedDataBufferList.java:101)
    Suppressed: reactor.core.publisher.FluxOnAssembly$OnAssemblyException

您现在如何在webflux中解决该问题?

Do you now how to resolve that in webflux ?

推荐答案

这个为我工作的人

1. 在您的配置类或主Springbootapplication类中创建一个Bean

1. Create a bean in your one of the configuration class or the main Springbootapplication class

@Bean
public WebClient getWebClientBuilder(){
    return   WebClient.builder().exchangeStrategies(ExchangeStrategies.builder()
            .codecs(configurer -> configurer
                      .defaultCodecs()
                      .maxInMemorySize(16 * 1024 * 1024))
                    .build())
                  .build();
}

下一步转到您要在其中使用网络客户端的所需课程

Next go to your desired class where you want to use the webclient

  @RestController / @Bean/ @Service
   public class PaySharpGatewayController {
        @Autowired
        WebClient webClient;

        public void test(){
         String out = webClient
                      .get()
                      .uri("end point of an API")
                      .retrieve()
                      .bodyToMono(String.class)
                     .block();

         sysout(out)
        }
