私はJava Webサービスを持っています

その中で、応答を呼び出すオブジェクトを返したい

同じ親タイプのオブジェクトがいくつかあります

public class ParentType{
         public ParentType();
}

public class Childtype1 extends ParentType{

}

public class Childtype2 extends ParentType{

}

public class Response{

ParentType data;
}

私の問題は、childtype1のオブジェクトを返すと、すべてがうまくいくことです

しかし、childtype2 のオブジェクトを返そうとすると、データ オブジェクトは空に戻ります

私はこれにAxisを使用しています。

childtype1 と childtype2 の両方がデータを返すようにする方法は?

これは実際のコードです：

public class ServerObject{
public ServerObject(){
}
//this is really an empty class, nothing written here besides this
}

public User extends ServerObject(){
private int userID = 0;
private String firstName = "N/A";
private String lastName = "N/A";
private String login;
private String password = "N/A";
private int authLevel = 0;
private String address = "N/A";
private String phone = "N/A";
private String email = "N/A";

public User(){
super();
}
public int getUserID() {
return userID;
}

public void setUserID(int userID) {
this.userID = userID;
}

public String getFirstName() {
return firstName;
}

public void setFirstName(String firstName) {
this.firstName = firstName;
}

public String getLastName() {
return lastName;
}

public void setLastName(String lastName) {
this.lastName = lastName;
}

public String getLogin() {
return login;
}

public void setLogin(String login) {
this.login = login;
}

public String getPassword() {
return password;
}

public void setPassword(String password) {
this.password = password;
}

public int getAuthLevel() {
return authLevel;
}

public void setAuthLevel(int authLevel) {
this.authLevel = authLevel;
}

public String getAddress() {
return address;
}

public void setAddress(String address) {
this.address = address;
}

public String getPhone() {
return phone;
}

public void setPhone(String phone) {
this.phone = phone;
}

public String getEmail() {
return email;
}

public void setEmail(String email) {
this.email = email;
}

@Override
public String toString() {
return "User [userID=" + userID + ", firstName=" + firstName + ", lastName=" + lastName + ", login=" + login + ", password=" + password + ", authLevel=" + authLevel + ", address=" + address
+ ", phone=" + phone + ", email=" + email + "]";
}



}

public class UserLoginInformation extends ServerObject{
private int userID = 0;
private long lastSeen=System.currentTimeMillis();
private boolean loggedIn = false;
private String login="N/A";

public int getUserID() {
return userID;
}

public boolean isLoggedIn() {
return loggedIn;
}

public void setLoggedIn(boolean loggedIn) {
this.loggedIn = loggedIn;
this.lastSeen = System.currentTimeMillis();
}

public void setLogin(String login) {
this.login = login;
}
public String getLastSeen() {
return lastSeen+"";
}

public String getLogin() {
return login;
}

public void setUserID(int userID) {
this.userID = userID;
}

public void setLastSeen(long lastSeen) {
this.lastSeen = lastSeen;
}

@Override
public String toString() {
return "UserLoginInformation [userID=" + userID + ", lastSeen=" + lastSeen + ", loggedIn=" + loggedIn + ", login=" + login + "]";
}

}

public class ServerResponse{

ServerObject data;
int status;
String message;

public ServerResponse(){
//also empty constructor, does nothing
}
public ServerObject getData(){
Log.info(data);
return data;
}
public int getStatus(){
return status;
}

public String getMessage(){
return message;
}

public void setData(ServerObject data){
this.data = data;
}
public void setStatus(int status){
this.status = status;
}

public void setMessage(String message){
this.message = message;
}

@Override
public String toString{
return "ServerResponse [data="+data+" status = " +status + " message= "+message]";
}
}

答えはここにあります: http://www.ibm.com/developerworks/websphere/techjournal/0401_brown/brown.html

簡単な解決策は、いくつかの方法を作成します

public ChildType1 childType1(){
return new ChildType1();
}

public ChildType1 childType2(){
    return new ChildType2();
    }

そして、すべてが正常に動作します
