Java-检查under_score字符串是否在lowerCamel字符串列表中

Question

考虑以下键(under_score)和字段(lowerCamel):

keys   = ["opened_by","ticket_owner","close_reason"]
fields = ["openedBy","ticketOwner","closeReason"]

我正在Java中寻找一种有效的方法来检查key是否在fields中，我希望以下返回true:

fields = ["openedBy","ticketOwner"]

return fields.contains("opened_by"))   //true

我的代码：

Set<String> incidentFields = Arrays
            .stream(TicketIncidentDTO.class.getDeclaredFields())
            .map(Field::getName)
            .collect(Collectors.toSet()
            );


responseJson.keySet().forEach(key ->{
           
            if (incidentFields.contains(key)) 
            {
                //Do something
            }
        });

我可以用下划线替换所有小写，但我正在寻找更有效的方法。

尝试使用来自公用文本的CaseUtils

// opened_by -> openedBy
private String toCamel(String str) {
    return CaseUtils.toCamelCase(str, false, new char[] { '_' });
}

List<String> keys = Arrays.asList("opened_by", "ticket_owner", "close_reason", "full_name");

List<String> fields = Arrays.asList("openedBy", "ticketOwner", "closeReason");

keys.forEach(t -> {
    // check
    if (fields.contains(toCamel(t))) {
        System.out.println(t);
    }
});
