往MySQL插入数据时,报错如下
java.sql.SQLException: Incorrect string value: 'xF0x9Fx91x88xE6x88...' for column 'content' at row 1 at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:127) at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:95) at com.mysql.cj.jdbc.exceptions.SQLExceptionsMapping.translateException(SQLExceptionsMapping.java:122) at com.mysql.cj.jdbc.ClientPreparedStatement.executeInternal(ClientPreparedStatement.java:960) at com.mysql.cj.jdbc.ClientPreparedStatement.execute(ClientPreparedStatement.java:388) at
因为emoji表情导致,有两种解决方法
一、过滤掉字段中的emoji
import org.apache.commons.lang.StringUtils; /** * @author: FengZhen * @create: 2019-02-25 */ public class EmojiFilter { private static boolean isEmojiCharacter(char codePoint) { return (codePoint == 0x0) || (codePoint == 0x9) || (codePoint == 0xA) || (codePoint == 0xD) || ((codePoint >= 0x20) && (codePoint <= 0xD7FF)) || ((codePoint >= 0xE000) && (codePoint <= 0xFFFD)) || ((codePoint >= 0x10000) && (codePoint <= 0x10FFFF)); } /** * 过滤emoji 或者 其他非文字类型的字符 * * @param source * @return */ public static String filterEmoji(String source) { if (StringUtils.isBlank(source)) { return source; } StringBuilder buf = null; int len = source.length(); for (int i = 0; i < len; i++) { char codePoint = source.charAt(i); if (isEmojiCharacter(codePoint)) { if (buf == null) { buf = new StringBuilder(source.length()); } buf.append(codePoint); } } if (buf == null) { return source; } else { if (buf.length() == len) { buf = null; return source; } else { return buf.toString(); } } } }
二、将表编码设置为utf8mb4
若需还原展示该字段,则建议此种方式。
