jackson和fastJson || Base64

jackson和fastJson || Base64

1. jackson和fastJson 实现对象转json字符串体验; 2. Base64 编码和解码体验;

public class Test01 {
    public static void main(String[] args) throws JsonProcessingException {
        Article article = new Article();
        article.setId(22);
        article.setTitle("你好 中国");
        article.setContent("我和我的祖国");

        System.out.println("1: "+article);
        System.out.println("2: "+new ObjectMapper().writeValueAsString(article));//jackson
        System.out.println("3: "+JSON.toJSONString(article));//fastJson
        
        String s1 = Base64.getEncoder().encodeToString(JSON.toJSONString(article).getBytes(StandardCharsets.UTF_8));
        String s2 = new String(Base64.getDecoder().decode(s1));

        System.out.println("4: "+s1);
        System.out.println("5: "+s2);

        String s = Base64.getEncoder().encodeToString(new ObjectMapper().writeValueAsBytes(article));
        String s3 =new String(Base64.getDecoder().decode(s)) ;
        System.out.println("6: "+s);
        System.out.println("7: "+s3);
    }
}
