配置在Application.Java启动类（Spring boot、Spring cloud）：
使用FastJson
/** * 编辑fastJson.<br/> * * @return HttpMessageConverters * @author yunchao.li */ @Bean public HttpMessageConverters fastJsonHttpMessageConverters(){ //1、先定义一个convert转换消息的对象 FastJsonHttpMessageConverter fastConverter=new FastJsonHttpMessageConverter(); //2、添加fastjson的配置信息，比如是否要格式化返回的json数据； FastJsonConfig fastJsonConfig=new FastJsonConfig(); SerializerFeature[] serializerFeatures = new SerializerFeature[]{ // 输出key是包含双引号 // SerializerFeature.QuoteFieldNames, // 是否输出为null的字段,若为null 则显示该字段 // SerializerFeature.WriteMapNullValue, // 数值字段如果为null，则输出为0 // SerializerFeature.WriteNullNumberAsZero, // List字段如果为null,输出为[],而非null SerializerFeature.WriteNullListAsEmpty, // 字符类型字段如果为null,输出为"",而非null SerializerFeature.WriteNullStringAsEmpty, // Boolean字段如果为null,输出为false,而非null SerializerFeature.WriteNullBooleanAsFalse, // Date的日期转换器 SerializerFeature.WriteDateUseDateFormat, // 循环引用 SerializerFeature.DisableCircularReferenceDetect, }; fastJsonConfig.setSerializerFeatures(serializerFeatures); //附加：处理中文乱码 List<MediaType> fastMedisTypes = new ArrayList<MediaType>(); fastMedisTypes.add(MediaType.APPLICATION_JSON_UTF8); fastConverter.setSupportedMediaTypes(fastMedisTypes); //3、在convert中添加配置信息 fastConverter.setFastJsonConfig(fastJsonConfig); HttpMessageConverter<?> converter=fastConverter; return new HttpMessageConverters(converter);}
