java - 通用集合和 XStream

Question

有没有办法映射(使用xstream)List<Person>至<friends>和List<Things>至<stuff>例如？

谢谢!

是的。

import com.thoughtworks.xstream.XStream;
import com.thoughtworks.xstream.io.xml.DomDriver;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;

public class XStreamTest {
    private List<Person> friends = new ArrayList<Person>();
    private List<Thing> stuff = new ArrayList<Thing>();

    public XStreamTest(List<Person> people, List<Thing> stuff) {
        this.friends.addAll(people);
        this.stuff.addAll(stuff);
    }

    private static class Person {
        private String name;

        public Person(String name) {
            this.name = name;
        }

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }


    }
    private static class Thing {
        private String description;

        public Thing(String description) {
            this.description = description;
        }

        public String getDescription() {
            return description;
        }

        public void setDescription(String description) {
            this.description = description;
        }

    };


    public static void main(String[] args) {
        XStream xstream = new XStream(new DomDriver());
        xstream.alias("test", XStreamTest.class);
        xstream.alias("person", Person.class);
        xstream.alias("thing", Thing.class);

        XStreamTest test = new XStreamTest(Arrays.asList(new Person("Fred")), Arrays.asList(new Thing("Xbox 360")));
        System.out.println(xstream.toXML(test));

    }
}

打印

<test>
  <friends>
    <person>
      <name>Fred</name>
    </person>
  </friends>
  <stuff>
    <thing>
      <description>Xbox 360</description>
    </thing>
  </stuff>
</test>
