xStream - Duas classes com nomes iguais, mas tipos diferentes

[Heur 0]

Olá pessoal.

Estou com um problemão, na leitura de um xml.

 

Eu peguei um xml, que não foi feito por mim. E tenho que ler, editar e escreve um xml

igual a esse.

 

O xml é bastante extenso e no meio do código um empasse...

 

há uma estrutura assim:

 

<activities>

 <activity>
    <id>1</id>
    <name>Activity 1</name>
 </activity>
 <activity>
    <id>1</id>
    <name>Activity 1</name>
    <time>4</time>
 </activity>

 <activity>
    <id>2</id>
    <name>Activity 2</name>
 </activity>
 <activity>
    <id>2</id>
    <name>Activity 2</name>
    <time>5</time>
 </activity>

 <activity>
    <id>3</id>
    <name>Activity 3</name>
 </activity>
 <activity>
    <id>3</id>
    <name>Activity 3</name>
    <time>6</time>
 </activity>

</activities>

 

Explicando. Eu tenho tags <activity> com dados diferentes.

E no xstream, eu to tentando colocar essas tags dentro de uma classe Activity.

 

Por exemplo:

public class Activity {

  private int id;
  private String name;
  private int time;

}

 

Eu fiz os getter e setters para essa classe. Dessa forma, eu devo colocar, para ler a tag <activities> dentro

de uma array, assim:

 

public class Activities {

   private List<Activity> activities = new ArrayList<Activity>();

   public void add(Activity atv) {
       this.activities.add(atv);
   }

   public List<Activity> getContent() {
       return this.activities;
   }
}

 

Porém, como vou fazer para inserir nessa array o outro tipo de tag?

 

As tags tem nomes iguais mais tipos de dados diferentes, ou à mais.

 

Alguém pode me ajudar?

 

Obrigado.

[void 1]

então temos:

 

public class Activity {
private int id;
private String name;
private int time;

public int getId() {
	return id;
}

public void setId(int id) {
	this.id = id;
}

public String getName() {
	return name;
}

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

public int getTime() {
	return time;
}

public void setTime(int time) {
	this.time = time;
}
}

 

import java.util.ArrayList;
import java.util.List;

public class Activities {
private List<Activity> activities = new ArrayList<Activity>();

public List<Activity> getActivities() {
	return activities;
}

public void setActivities(List<Activity> activities) {
	this.activities = activities;
}
}

 

você precisa fazer o seguinte...

 

import com.thoughtworks.xstream.annotations.XStreamAlias;

@XStreamAlias("activity")
public class Activity {
private int id;
private String name;
private int time;

public int getId() {
	return id;
}

public void setId(int id) {
	this.id = id;
}

public String getName() {
	return name;
}

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

public int getTime() {
	return time;
}

public void setTime(int time) {
	this.time = time;
}
}

import java.util.ArrayList;
import java.util.List;

import com.thoughtworks.xstream.annotations.XStreamAlias;
import com.thoughtworks.xstream.annotations.XStreamImplicit;

@XStreamAlias("activities")
public class Activities {

@XStreamImplicit
private List<Activity> activities = new ArrayList<Activity>();

public List<Activity> getActivities() {
	return activities;
}

public void setActivities(List<Activity> activities) {
	this.activities = activities;
}
}

 

executando isso:

import java.util.ArrayList;

import com.thoughtworks.xstream.XStream;

public class Test {
public static void main(String[] args) throws Exception {
	XStream xs = new XStream();
	xs.processAnnotations(Activities.class);
	xs.processAnnotations(Activity.class);

	Activity activity = new Activity();
	activity.setId(1);
	activity.setName("Activity 1");
	activity.setTime(4);

	Activity activity2 = new Activity();
	activity2.setId(2);
	activity2.setName("Activity 2");

	Activity activity3 = new Activity();
	activity3.setId(3);
	activity3.setName("Activity 3");
	activity3.setTime(6);

	Activity activity4 = new Activity();
	activity4.setId(4);
	activity4.setName("Activity 4");

	Activities activities = new Activities();
	activities.setActivities(new ArrayList<Activity>());
	activities.getActivities().add(activity);
	activities.getActivities().add(activity2);
	activities.getActivities().add(activity3);
	activities.getActivities().add(activity4);

	System.out.println(xs.toXML(activities));
}
}

 

o resultado é:

<activities>
 <activity>
   <id>1</id>
   <name>Activity 1</name>
   <time>4</time>
 </activity>
 <activity>
   <id>2</id>
   <name>Activity 2</name>
   <time>0</time>
 </activity>
 <activity>
   <id>3</id>
   <name>Activity 3</name>
   <time>6</time>
 </activity>
 <activity>
   <id>4</id>
   <name>Activity 4</name>
   <time>0</time>
 </activity>
</activities>

 

é claro que o time vai aparecer zero pq o tipo é int se fosse integer quando não setado seria null ai o xstream omite!
