Question

我正在尝试使用Jackson XmlMapper将POJO转换为xml。我过去曾将此库用于json，但问题是它不适用于xml atm。有人可以帮我解决为什么会发生这种情况吗？我是新来的。

public class Pojo {

    public int x = 0;
}

import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.dataformat.xml.XmlMapper;

public class Serialization {

    public static void main(String[] args) throws JsonProcessingException {
        XmlMapper mapper = new XmlMapper();
        String xml = mapper.writeValueAsString(new Pojo());
        System.out.println(xml);
    }

}

我得到的错误如下：
