fast JSON 配置

springboot启动类中配置

@SuppressWarnings("serial")
	@Bean
    public HttpMessageConverters fastJsonHttpMessageConverters() {
	   FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();
       FastJsonConfig fastJsonConfig = new FastJsonConfig();
       fastJsonConfig.setSerializerFeatures(SerializerFeature.DisableCircularReferenceDetect);	//禁止循环引用探测
       fastConverter.setSupportedMediaTypes(new ArrayList<MediaType>(){{add(MediaType.APPLICATION_JSON_UTF8);}});
       fastConverter.setFastJsonConfig(fastJsonConfig);
       HttpMessageConverter<?> converter = fastConverter;
       return new HttpMessageConverters(converter);
}

如果少配置下面这一段，该转换器会匹配到不想让它匹配的controller.. （小坑)

fastConverter.setSupportedMediaTypes(new ArrayList<MediaType>(){{add(MediaType.APPLICATION_JSON_UTF8);}});

pom引入
