Collection
<Emoji> collection

System

System

.println("parseToAliases");
System
.out
.println(EmojiParser
.parseToHtmlDecimal(str3
, EmojiParser
.FitzpatrickAction
.PARSE
));
System
.out
.println(EmojiParser
.parseToHtmlDecimal(str3
, EmojiParser
.FitzpatrickAction
.REMOVE
));
System
.out
.println(EmojiParser
.parseToHtmlDecimal(str3
, EmojiParser
.FitzpatrickAction
.IGNORE
));
}
}
解决的方法二:
保证数据库的版本，可以使用utf-8mb4的字符集，库，表，字段的字符集都使用utf8mb4。字段的排序规则为unicode_ci
