XSTREAM解析

Question

我有一些XML是與我不能從XML轉移到對象中的屬性單級：

<?xml version="1.0" encoding="utf-8"?> 
<response status="426"> 
You can add 15 clients with your current plan. 
</response> 

此XML表示這個POJO

public class ClientGenericResponse { 
    String response; 
    String status; 
    ClientID client_id; 

    public String getResponse() { 
     return response; 
    } 

    public void setResponse(String response) { 
     this.response = response; 
    } 

    public String getStatus() { 
     return status; 
    } 

    public void setStatus(String status) { 
     this.status = status; 
    } 

    public ClientID getClient_id() { 
     return client_id; 
    } 

    public void setClient_id(ClientID clientId) { 
     client_id = clientId; 
    } 

使用此代碼，我可以得到的XStream，找到「狀態」屬性，但我似乎無法找到響應節點的文本值。

// Map response object 
    xstream = new XStream(); 
    xstream.alias("response", ClientGenericResponse.class); 

    xstream.useAttributeFor(ClientGenericResponse.class, "status"); 
    xstream.aliasField("status", ClientGenericResponse.class, "status"); 

    // Send request (this retrieves the xml above) 
    String xmlResponse = Utility.sendRequest(xml, true); 

    ClientGenericResponse response = (ClientGenericResponse)xstream.fromXML(xmlResponse); 

在這種情況下，響應對象的狀態已填充，但不是文本。

似乎很基本，我可以得到完整的對象乾淨地來回移動，當有根節點內的標籤，但對於這個單標籤的情況下，我無法獲得內容。

我看到「不支持混合XML」來引用，並在頂部的XML代表「混合」？

您需要使用​​，它支持將一個字段成員定義爲值並將所有其他字段成員寫爲屬性。

，如下圖所示這是很容易做到這一點使用XStream的註釋：HTTP：

import com.thoughtworks.xstream.XStream; 
import com.thoughtworks.xstream.annotations.XStreamAlias; 
import com.thoughtworks.xstream.annotations.XStreamConverter; 
import com.thoughtworks.xstream.converters.extended.ToAttributedValueConverter; 

@XStreamAlias("response") 
@XStreamConverter(value=ToAttributedValueConverter.class, strings={"response"}) 
public class ClientGenericResponse { 

    String response; 

    @XStreamAlias("type") 
    String status; 

    ClientID client_id; 

    public String getResponse() { 
     return response; 
    } 

    public void setResponse(String response) { 
     this.response = response; 
    } 

    public String getStatus() { 
     return status; 
    } 

    public void setStatus(String status) { 
     this.status = status; 
    } 

    public ClientID getClient_id() { 
     return client_id; 
    } 

    public void setClient_id(ClientID clientId) { 
     client_id = clientId; 
    } 

    public static void main(String[] args) { 

     XStream xstream = new XStream(); 
     xstream.processAnnotations(ClientGenericResponse.class); 

     // Send request (this retrieves the xml above) 
     String xmlResponse = Utility.sendRequest(xml, true); 

     ClientGenericResponse response = (ClientGenericResponse)xstream.fromXML(xmlResponse); 
    } 
}
