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无名。
