老哥们，请教一个 Jackson xml 序列化的问题。

我想要得到和这个链接中提到的结构： https://www.coder.work/article/5554449

但是我用 jackson 的注解无法实现。

只使用 jaxb 可以，但是 jaxb 对 CDATA 的支持不行,jackson + jaxb 得不到想要的结果。这两个混合不行。

代码:

@Data
@JacksonXmlRootElement(localName = "articles")
public class Articles {

    private String uuid;

    
    List<ArticleContent> contents;

    public static void main(String[] args) throws JsonProcessingException {

        Articles articles = new Articles();

        articles.setUuid("uuid");


        ArticleContent text1 = new Text("text1");

        ArticleContent video1 = new Video("www.video1.com");

        ArticleContent text2 = new Text("text1");

        ArticleContent video2 = new Video("www.video1.com");


        articles.setContents(Arrays.asList(text1,video1,text2,video2));


        XmlMapper mapper = new XmlMapper();


        System.out.println(mapper.writeValueAsString(articles));


    }

}


@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.WRAPPER_OBJECT)
@JsonSubTypes({
        @JsonSubTypes.Type(name = "text", value = Text.class),
        @JsonSubTypes.Type(name = "video", value = Video.class)
})

public abstract class ArticleContent {

}

@Data
@AllArgsConstructor
public class Text extends ArticleContent {

    private String content;

}

@Data
@AllArgsConstructor
public class Video extends  ArticleContent{

    String url;

}

pom 依赖:


        <dependency>
            <groupId>com.fasterxml.jackson.dataformat</groupId>
            <artifactId>jackson-dataformat-xml</artifactId>
            <version>2.11.0</version>
        </dependency>

        <dependency>

            <version>1.18.8</version>
            <scope>provided</scope>
        </dependency>

想要的 xml：

<articles>
   <uuid>uuid</uuid>
   <contents>
     <text>
        <content>text1</content>
     </text>
 
     <video>
        <url>www.video1.com</url>
     </video>
 
     <text>
        <content>text1</content>
     </text>
 
     <video>
        <url>www.video1.com</url>
     </video>
   </contents>
</articles>

上面代码实际得到的 xml:

<?xml version="1.0" encoding="UTF-8"?>
<articles>
   <uuid>uuid</uuid>
   <contents>
      <contents>
         <text>
            <content>text1</content>
         </text>
      </contents>
      <contents>
         <video>
            <url>www.video1.com</url>
         </video>
      </contents>
      <contents>
         <text>
            <content>text1</content>
         </text>
      </contents>
      <contents>
         <video>
            <url>www.video1.com</url>
         </video>
      </contents>
   </contents>
</articles>
