Jackson 反序列化时实现大小写不敏感设置

常用配置

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);//大小写脱敏 默认为false  需要改为tru

参考

com.fasterxml.jackson.databind.MapperFeature#ACCEPT_CASE_INSENSITIVE_PROPERTIES

使用注解方式：举例

public static void main(String[] args) throws IOException {        String x = "{\n"            + "        \"TToUserName\":\"gh_a5624dd2db4e\",\n"            + "        \"FFromUserName\":\"ochvq0Kn35VlnTAcIJ3fRBAZTQUY\""            + "       }";         ObjectMapper objectMapper = new ObjectMapper();        Result map = objectMapper.readValue(x, Result.class);        System.out.println(map);        objectMapper.writeValue(System.out,map);    }      private static class Result {         private String ToUserName;        private String FromUserName;         @JsonProperty("ToUserName")        public String getToUserName() {            return ToUserName;        }         @JsonProperty("TToUserName")        public void setToUserName(String toUserName) {            ToUserName = toUserName;        }         @JsonProperty("FromUserName")        public String getFromUserName() {            return FromUserName;        }         @JsonProperty("FFromUserName")        public void setFromUserName(String fromUserName) {            FromUserName = fromUserName;        }    }

Jackson 转换大小写问题

Jackson转换json时会把大写转换成小写

解决办法：

1、在变量时加上： @JsonProperty

2、在set/get方法加上：@JsonIgnore

以上为个人经验，希望能给大家一个参考，也希望大家多多支持。
