maven依赖

<dependency>

</dependency>

使用

String str = "你?好?啊";
        System.out.println("原始字符为：\n" + str);
 
    
        //将表情转换成对应别名字符（to aliases）
        System.out.println("to aliases 之后：");
        System.out.println(EmojiParser.parseToAliases(str));
        System.out.println(EmojiParser.parseToAliases(str, EmojiParser.FitzpatrickAction.PARSE));
        System.out.println(EmojiParser.parseToAliases(str, EmojiParser.FitzpatrickAction.REMOVE));
        System.out.println(EmojiParser.parseToAliases(str, EmojiParser.FitzpatrickAction.IGNORE));
 
 
        //将表情转换成html（to html）        
        System.out.println("to html：");
        System.out.println(EmojiParser.parseToHtmlDecimal(str));
        System.out.println(EmojiParser.parseToHtmlDecimal(str, EmojiParser.FitzpatrickAction.PARSE));
        System.out.println(EmojiParser.parseToHtmlDecimal(str, EmojiParser.FitzpatrickAction.REMOVE));
        System.out.println(EmojiParser.parseToHtmlDecimal(str, EmojiParser.FitzpatrickAction.IGNORE));
	
        System.out.println("to html：");
        String s = EmojiParser.parseToHtmlDecimal(str);
        System.out.println(s);
 
        System.out.println("还原：");
        System.out.println(EmojiParser.parseToUnicode(s));
        
        Letter l = new Letter();
        l.setDetails(EmojiParser.parseToAliases(str));
        
        letterMapper.insertLetter(l);

输出结果： 

存入数据库的内容为：
