HttpMessageConverters-spring-boot(1.5.6)-cloudfeign1.3.4 学习笔记

概述

springboot—->HttpMessageConverters

当创建HttpMessageConverters时,会调用getDefaultConverters获取WebMvcConfigurationSupport中配置的转换器

而getCombinedConverters会将用户配置的转换器放置在默认转换器之前—->combined.addAll(0, processing)

cloud-feign中利用HttpMessageConverters进行消息的转换

当EnableFeignClients时候,会引入FeignClientsConfiguration配置feign相关的Decoder/Encoder

Decoder通过new ResponseEntityDecoder(new SpringDecoder(this.messageConverters))引入配置的消息转换器

Encoder通过new SpringEncoder(this.messageConverters)引入配置的消息转换器

最终委托给HttpMessageConverterExtractor.extractData利用转换器转换消息
