Jackson 反序列化时实现大小写不敏感设置

ObjectMapper objectMapper = new ObjectMapper();

objectMapper.configure(Feature.IGNORE_UNKNOWN, true );

objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false );

objectMapper.configure(MapperFeature.ACCEPT_CASE_INSENSITIVE_PROPERTIES, false ); //大小写脱敏 默认为false  需要改为tru
