您可以这样配置自己的实例
MappingJackson2HttpMessageConverter：
@Configurationpublic class WebConfig extends WebMvcConfigurerAdapter { @Override public void extendMessageConverters(List<HttpMessageConverter<?>> converters) { ObjectMapper mapper = Jackson2ObjectMapperBuilder().json() .filters(new SimpleFilterProvider().addFilter("filter", new ExcludeIdFilter())); MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter(mapper); // then replace the default MappingJackson2HttpMessageConverter // with your custom one in the list of configured converters }}
