往MySQL插入数据时，报错如下
java.sql.SQLException: Incorrect string value: '\xF0\x9F\x91\x88\xE6\x88...' for column 'content' at row at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:) at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:) at com.mysql.cj.jdbc.exceptions.SQLExceptionsMapping.translateException(SQLExceptionsMapping.java:) at com.mysql.cj.jdbc.ClientPreparedStatement.executeInternal(ClientPreparedStatement.java:) at com.mysql.cj.jdbc.ClientPreparedStatement.execute(ClientPreparedStatement.java:) 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 = ; 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。
