亲测有效。恒标云测试系统中有源码。@Configurationpublic类WebMvcConfiguration实现WebMvcConfigurer{@OverridepublicvoidconfigureMessageConverters(List>converters){MappingJackson2HttpMessageConverterjackson2HttpMessageConverter=newMappingJackson2HttpMessageConverter();ObjectMapperobjectMapper=newObjectMapper();objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES,false);/***当sequence改成json时，所有的long都会改成strings*因为js中的numeric类型不能包含所有的javalong值*/SimpleModulesimpleModule=newSimpleModule();simpleModule.addSerializer(Long.class,ToStringSerializer.instance);simpleModule.addSerializer(Long.TYPE,ToStringSerializer.instance);objectMapper.registerModule(simpleModule);jackson2HttpMessageConverter.setObjectMapper(objectMapper);converters.add(0,jackson2HttpMessageConverter);}}
