jacksonデシリアライゼーションのサブクラスのリスト

Question

私は応答としてxmlを提供するはずのWebサービスに取り組んでいます。私はそのためにjacksonを使用しています。

package com.spinner.jackson; 
import java.util.ArrayList; 
import java.util.List; 

import com.fasterxml.jackson.annotation.JsonTypeInfo; 
import com.fasterxml.jackson.annotation.JsonUnwrapped; 
import com.fasterxml.jackson.annotation.JsonValue; 
import com.fasterxml.jackson.databind.annotation.JsonDeserialize; 
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlElementWrapper; 
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlProperty; 
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlText; 

public class ClientObject { 

    @JacksonXmlElementWrapper(useWrapping = false) 
    @JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.WRAPPER_OBJECT) 
    private List<MyItem> accounts; 

    public ClientObject(List<MyItem> pl) { 
     this.accounts = pl; 
    } 

    public ClientObject() { 
     this.accounts = new ArrayList<MyItem>(); 
    } 

    @JsonDeserialize(using = CustomDeserial.class) 
    public void setL(List<MyItem> l) { 
     this.accounts = l; 
    } 

    public List<MyItem> getAccounts() { 
     // TODO Auto-generated method stub 
     return this.accounts; 
    } 
} 

、その後、私は次のようにサブのクラスがあります：私は、私は抽象クラスを持って、問題で立ち往生しています

パッケージcom.spinner.jacksonを。

import javax.xml.bind.annotation.XmlRootElement; 
import com.fasterxml.jackson.annotation.JsonCreator; 
import com.fasterxml.jackson.annotation.JsonProperty; 
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlRootElement; 

@JacksonXmlRootElement(localName="itemA") 
public class MySubItemA extends MyItem { 

    public MySubItemA() { 
     super(); 
     // TODO Auto-generated constructor stub 
    } 

    public MySubItemA(int id, String name) { 
     super(id, name); 
     // TODO Auto-generated constructor stub 
    } 

    private String itemAProperty1; 
    private String itemAProperty2; 

    public String getItemAProperty1() { 
     return this.itemAProperty1; 
    } 

    public void setItemAProperty1(String itemAProperty1) { 
     this.itemAProperty1 = itemAProperty1; 
    } 

    public String getItemAProperty2() { 
     return this.itemAProperty2; 
    } 

    public void setItemAProperty2(String itemAProperty2) { 
     this.itemAProperty2 = itemAProperty2; 
    } 

    @JsonCreator 
    public MySubItemA(@JsonProperty("id")int id, @JsonProperty("name")String name, @JsonProperty("itemAProperty1")String p1, @JsonProperty("itemAProperty2")String p2) { 
     super(id, name); 
     this.itemAProperty1 = p1; 
     this.itemAProperty2 = p2; 
    } 

} 

別のサブクラス

package com.spinner.jackson; 

import javax.xml.bind.annotation.XmlRootElement; 

import com.fasterxml.jackson.annotation.JsonProperty; 
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlRootElement; 

@JacksonXmlRootElement(localName="itemB") 
public class MySubItemB extends MyItem { 

    private int itemBProperty1; 
    private String itemBProperty2; 

    public int getItemBProperty1() { 
     return this.itemBProperty1; 
    } 

    public void setItemBProperty1(int itemBProperty1) { 
     this.itemBProperty1 = itemBProperty1; 
    } 

    public String getItemBProperty2() { 
     return this.itemBProperty2; 
    } 

    public void setItemBProperty2(String itemBProperty2) { 
     this.itemBProperty2 = itemBProperty2; 
    } 

    public MySubItemB(@JsonProperty("id")int id, @JsonProperty("name")String name, @JsonProperty("itemBProperty1")int p1, @JsonProperty("itemBProperty2")String p2) { 
     super(id, name); 
     this.itemBProperty1 = p1; 
     this.itemBProperty2 = p2; 
    } 
} 

とクライアントクラスに続くとおり

package com.spinner.jackson; 
import java.util.ArrayList; 
import java.util.List; 

import com.fasterxml.jackson.annotation.JsonTypeInfo; 
import com.fasterxml.jackson.annotation.JsonUnwrapped; 
import com.fasterxml.jackson.annotation.JsonValue; 
import com.fasterxml.jackson.databind.annotation.JsonDeserialize; 
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlElementWrapper; 
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlProperty; 
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlText; 

public class ClientObject { 

    @JacksonXmlElementWrapper(useWrapping = false) 
    @JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.WRAPPER_OBJECT) 
    private List<MyItem> accounts; 

    public ClientObject(List<MyItem> pl) { 
     this.accounts = pl; 
    } 

    public ClientObject() { 
     this.accounts = new ArrayList<MyItem>(); 
    } 

    @JsonDeserialize(using = CustomDeserial.class) 
    public void setL(List<MyItem> l) { 
     this.accounts = l; 
    } 

    @JsonDeserialize(using = CustomDeserial.class) 
    public List<MyItem> getAccounts() { 
     // TODO Auto-generated method stub 
     return this.accounts; 
    } 
} 

MYITEMクラス：上記

package com.spinner.jackson; 

import javax.xml.bind.annotation.XmlRootElement; 

import com.fasterxml.jackson.annotation.JsonSubTypes; 
import com.fasterxml.jackson.annotation.JsonSubTypes.Type; 
import com.fasterxml.jackson.annotation.JsonTypeInfo; 
import com.fasterxml.jackson.annotation.JsonTypeInfo.Id; 

@XmlRootElement 
public abstract class MyItem { 


    public MyItem() { 
     super(); 
     // TODO Auto-generated constructor stub 
    } 

    private int id; 
    private String name; 

    public int getId() { 
     return this.id; 
    } 

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

    public String getName() { 
     return this.name; 
    } 

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

    public MyItem(int id, String name) { 
     this.id = id; 
     this.name = name; 
    } 

} 

続い

0123として出力XMLを生成します

<ClientObject> 
    <accounts> 
     <MySubItemA> 
      .... 
     </MySubItemA> 
    </accounts> 
    <accounts> 
     <MySubItemB> 
      .... 
     </MySubItemB> 
    </accounts> 
</ClientObject> 

<ClientObject> 
    <accounts> 
     <accounts> 
      <MySubItemA> 
       .... 
      </MySubItemA> 
     </accounts> 
     <accounts> 
      <MySubItemB> 
       ..... 
      </MySubItemB> 
     </accounts> 
    </accounts> 
</ClientObject> 

ので、最終的な出力があるべき

を以下のように私はそれが何かをこの注釈を削除する場合にも、私は@JacksonXmlElementWrapper（useWrapping = false）を使用していていても <accounts>ラッパーを削除する方法があります

<ClientObject> 
     <MySubItemA> 
      .... 
     </MySubItemA> 
     <MySubItemB> 
      .... 
     </MySubItemB> 
</ClientObject> 

ご協力いただきありがとうございます。

Answer 1

私はので、私はそれが他の誰かを助けるかもしれないと思うそれを把握することができた：

私はシリアライザ

package com.spinner.jackson; 

import java.io.IOException; 
import com.fasterxml.jackson.core.JsonGenerator; 
import com.fasterxml.jackson.core.JsonProcessingException; 
import com.fasterxml.jackson.databind.JsonSerializer; 
import com.fasterxml.jackson.databind.SerializerProvider; 

public class MySerial extends JsonSerializer<ClientObject> 
{ 
    public void serialize(ClientObject value, JsonGenerator jgen, 
SerializerProvider provider) 
     throws IOException, JsonProcessingException 
    { 
     jgen.writeObjectFieldStart(value.getClass().getSimpleName()); 
     jgen.writeObjectField(value.getAccounts().get(0).getClass().getSimpleName(), value.getAccounts().get(0)); 
     jgen.writeObjectField(value.getAccounts().get(1).getClass().getSimpleName(), value.getAccounts().get(1)); 
     jgen.writeObjectField(value.getAccounts().get(2).getClass().getSimpleName(), value.getAccounts().get(2)); 
     jgen.writeObjectField(value.getAccounts().get(3).getClass().getSimpleName(), value.getAccounts().get(3)); 

    } 

} 

と私はClientObjectに次なかった次を作成しました。 java：

package com.spinner.jackson; 

import java.util.ArrayList; 
import java.util.List; 
import com.fasterxml.jackson.annotation.JsonTypeInfo; 
import com.fasterxml.jackson.databind.annotation.JsonSerialize; 
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlElementWrapper; 

@JsonSerialize(using = CustomDeserial.class) 
public class ClientObject { 

    @JacksonXmlElementWrapper(useWrapping = false) 
    @JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.WRAPPER_OBJECT) 
    private List<MyItem> accounts; 

    public ClientObject(List<MyItem> pl) { 
     this.accounts = pl; 
    } 

    public ClientObject() { 
     this.accounts = new ArrayList<MyItem>(); 
    } 

    public void setL(List<MyItem> l) { 
     this.accounts = l; 
    } 

    public List<MyItem> getAccounts() { 
     return this.accounts; 
    } 
} 

となりました.hこれはいくつかの助けになります。
