Question

假设我有这样的XML：

<host name="myHost">
  <service>
    <type>TYPE1</type>
    <field1>The content of field 1</field1>
  </service>
  <service>
    <type>TYPE2</type>
    <field2>The content of field 2</field2>
  </service>
</host>

有一种方法（使用JAXB / XStream）说“当你在TYPE1中找到服务中的元素时使用Type1的POJO /当你在TYPE2中找到一个服务元素时，使用一个类型为2的POJO ？

我需要使用它来使用泛型标记，此标记的类型将在解组过程中使用的POJO类有所不同

使用XStream - ＆gt;如果服务是列表对象，您将能够以这种格式进行...

＆＃13;

<Host>
  <name>myHost</name>
  <service>
    <Child1>
      <type>TYPE1</type>
      <field1>The content of field 1</field1>
    </Child1>
    <Child2>
      <type>TYPE2</type>
      <field2>The content of field 2</field2>
    </Child2>
  </service>
</Host>

＆＃13;

代码从这里开始

public class BaseObj {
private String type; }


public class Child1 extends BaseObj {
    private String field1;
}
public class Child2 extends BaseObj{
    private String field2;
}
public class Host {
    private String name;
    private List<BaseObj> service
}
public class TestXStream {

    public static void main(String[] args) {
        List<BaseObj> objects = new ArrayList<BaseObj>();
        Child1 obj1 = new Child1();
        obj1.setType("TYPE1");
        obj1.setField1("The content of field 1");
        Child2 obj2 = new Child2();
        obj2.setType("TYPE2");
        obj2.setField2("The content of field 2");
        objects.add(obj1);
        objects.add(obj2);
        Host host = new Host();
        host.setName("myHost");
        host.setService(objects);
        try {
            File test = new File("C:/resources/test_id.xml");
            new XStream().toXML(host, new FileOutputStream(test));
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

JAXB / XStream - 通过特定标记
