@RequestBody 多传字段异常解决方法

    @Bean
    public MappingJackson2HttpMessageConverter getMappingJackson2HttpMessageConverter() {
        MappingJackson2HttpMessageConverter mappingJackson2HttpMessageConverter = new MappingJackson2HttpMessageConverter();
        //设置日期格式
        ObjectMapper objectMapper = new ObjectMapper();
        SimpleDateFormat smt = new SimpleDateFormat("yyyy-MM-dd");
        objectMapper.setDateFormat(smt);

        // 忽略不匹配的属性 或者 在响应对象上面添加 @JsonIgnoreProperties(ignoreUnknown = true)注解
        objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
        mappingJackson2HttpMessageConverter.setObjectMapper(objectMapper);
        //设置中文编码格式
        List<MediaType> list = new ArrayList<MediaType>();
        list.add(MediaType.APPLICATION_JSON_UTF8);
        mappingJackson2HttpMessageConverter.setSupportedMediaTypes(list);

        return mappingJackson2HttpMessageConverter;
    }
