回想项目发现中有用到fastjson因此查看config文件
@Configuration
public class FastJsonFormatConfig {
@Bean
public FastJsonHttpMessageConverter configureMessageConverters() {
//new FastJsonHttpMessageConverter instance converter
FastJsonHttpMessageConverter converter = new FastJsonHttpMessageConverter();
//new FastJsonConfig instacne config
FastJsonConfig config = new FastJsonConfig();
//
config.setSerializerFeatures(
// 保留map空的字段
SerializerFeature.WriteMapNullValue,
// 将String类型的null转成""
SerializerFeature.WriteNullStringAsEmpty,
// 将Number类型的null转成0
SerializerFeature.WriteNullNumberAsZero,
// 将List类型的null转成[]
SerializerFeature.WriteNullListAsEmpty,
// 将Boolean类型的null转成false
SerializerFeature.WriteNullBooleanAsFalse,
// 避免循环引用
SerializerFeature.DisableCircularReferenceDetect);
//
converter.setFastJsonConfig(config);
//
converter.setDefaultCharset(StandardCharsets.UTF_8);
//
List<MediaType> mediaTypeList = new ArrayList<>();
// 解决中文乱码问题，相当于在Controller上的@RequestMapping中加了个属性produces = "application/json"
mediaTypeList.add(MediaType.APPLICATION_JSON);
//
converter.setSupportedMediaTypes(mediaTypeList);
//
return converter;
}
}
如果在配置Fastjson的时候继承 WebMvcConfigurationSupport这个类会导致swagger3静态资源失效，需要重新引入，当然不在本文分析范围之内。
// 解决中文乱码问题，相当于在Controller上的@RequestMapping中加了个属性produces = "application/json"
mediaTypeList.add(MediaType.APPLICATION_JSON);
//
converter.setSupportedMediaTypes(mediaTypeList);
重点是这一行，设置此转换器支持的 MediaType 对象列表。由于我需要请求头是各种类型所以，最简单的解决方案或称为急迫上线方案，是把converter.setSupportedMediaTypes(mediaTypeList); 这一行注释掉或者是把媒体类型改为 mediaTypeList.add(MediaType.ALL);即可解决报错问题。
