最近在做一個APP,第三方登入的時候暱稱表情儲存報錯,

Caused by: java.sql.SQLException: Incorrect string value: '\xF0\x9F\x98...' for column 'nick_name' at row 1

我對資料庫的編碼,表格的編碼,欄位的編碼,my.ini配置檔案都進行了修改,將utf8改成了utf8mb4,還是不行,所以我放棄了這種方式,取而代之的有如下兩種方案

1.在存值取值的時候做處理

import org.apache.commons.codec.binary.Base64;

public String getNickname() {   
        try {
            nickName = new String(Base64.decodeBase64(nickname), "UTF-8");
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
        return nickName;
    }

    public void setNickname(String nickname) {
        try {
            nickname = Base64.encodeBase64String(nickname.getBytes("UTF-8"));
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
        this.nickname = nickname;
    }
 

2.沒辦法的辦法,將所有Emoji過濾成其他字元

import java.util.regex.Matcher;
import java.util.regex.Pattern;
/**
 * @Description
 * @Author zk
 * @createTime 2018/12/14 10:00
 */
public class EmojiUtil {
    public static String filterEmoji(String nick_name) {
        //nick_name 所獲取的使用者暱稱
        if (nick_name == null) {
            return nick_name;
        }
        Pattern emoji = Pattern.compile("[\ud83c\udc00-\ud83c\udfff]|[\ud83d\udc00-\ud83d\udfff]|[\u2600-\u27ff]",
                Pattern.UNICODE_CASE | Pattern.CASE_INSENSITIVE);
        Matcher emojiMatcher = emoji.matcher(nick_name);
        if (emojiMatcher.find()) {
            //將所獲取的表情轉換為*
            nick_name = emojiMatcher.replaceAll("(表情)");
            return nick_name;
        }
        return nick_name;
    }
}
 

希望能夠幫到大家
