ObjectMapper objectMapper = new ObjectMapper();objectMapper.configure(Feature.IGNORE_UNKNOWN,true);objectMapper.configure(Feature.WRITE_BIGDECIMAL_AS_PLAIN,true);objectMapper.configure(JsonParser.Feature.ALLOW_MISSING_VALUES,true);objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES,false);objectMapper.configure(MapperFeature.ACCEPT_CASE_INSENSITIVE_PROPERTIES,false);//大小寫脫敏 默認為false 需要改為tru |

Jackson 轉換大小寫問題
Jackson轉換json時會把大寫轉換成小寫
解決辦法：
1、在變量時加上： @JsonProperty
2、在set/get方法加上：@JsonIgnore
以上為個人經驗，希望能給大家一個參考，也希望大家多多支持服務器之家。
