Answer 1

我发现，如果仅将YAML HttpMessageConverter注册为bean webflux，它将自动使用它。

Answer 2

我知道这很久了，但是在挖掘并没有找到答案之后，我终于能够使用大量不同的帖子将它们拼凑在一起，希望在这里帮助未来的人。

/**
 * Modelled off of Jackson2JsonDecoder
 */
public class Jackson2YamlDecoder extends AbstractJackson2Decoder {
    public Jackson2YamlDecoder() {
        super(YAMLMapper.builder().build(), new MimeType("application","x-yaml"));
    }
}

/**
 * Modelled off of Jackson2JsonEncoder
 */
public class Jackson2YamlEncoder extends AbstractJackson2Encoder {
    @Nullable
    private final PrettyPrinter ssePrettyPrinter;

    public Jackson2YamlEncoder() {
        super(YAMLMapper.builder().build(), new MimeType("application","x-yaml"));
        this.ssePrettyPrinter = initSsePrettyPrinter();
    }

    private static PrettyPrinter initSsePrettyPrinter() {
        DefaultPrettyPrinter printer = new DefaultPrettyPrinter();
        printer.indentObjectsWith(new DefaultIndenter("  ", "\ndata:"));
        return printer;
    }

    @Override
    protected ObjectWriter customizeWriter(ObjectWriter writer, MimeType mimeType, ResolvableType elementType, Map<String, Object> hints) {
        return this.ssePrettyPrinter != null && MediaType.TEXT_EVENT_STREAM.isCompatibleWith(mimeType) && writer.getConfig().isEnabled(SerializationFeature.INDENT_OUTPUT) ? writer.with(this.ssePrettyPrinter) : writer;
    }
}

@Configuration
public class WebFluxConfig implements WebFluxConfigurer {
    @Override
    public void configureHttpMessageCodecs(ServerCodecConfigurer configurer) {
        CodecConfigurer.CustomCodecs customCodecs = configurer.customCodecs();
        customCodecs.registerWithDefaultConfig(new Jackson2YamlDecoder());
        customCodecs.registerWithDefaultConfig(new Jackson2YamlEncoder());
    }
}

RestController的配置将YAML反序列化为pojo上传为原始文件吗？
