使用 XStream 來轉換 xml，xml轉為 Pojo（實體類），xml轉為map

    <dependency> <!-- xml與java pojo 映射類庫 -->
        <groupId>com.thoughtworks.xstream</groupId>
        <artifactId>xstream</artifactId>
        <version>1.4.10</version>
    </dependency>

實現類：

import com.thoughtworks.xstream.XStream;

/**
 * 使用 XStream 來轉換 xml <---> Java Pojo
 *
 * @since: v1.0
 */
public class XStreamFactory {

    /**
     * 將 xml 轉成 T 類型對象
     *
     * @param xml
     * @param clazz  要轉換的類型，如果為 null 則返回 null
     * @return
     */
    public final static <T> T fromXML(String xml, Class<T> clazz){
        if(clazz != null && !xml.equals("")){
            XStream xs = new XStream();
            XStream.setupDefaultSecurity(xs);
            xs.ignoreUnknownElements();
            xs.registerConverter(new MapEntryConverter());
            xs.processAnnotations(clazz);
            xs.allowTypes(new Class[]{clazz});
            
            return (T)xs.fromXML(xml);
        }
        
        return null;
    }
        
    /**
     * 將 xml 轉成 T 類型對象。（xml的根節點名稱與類名稱不相同時使用本方法）
     *
     * @param alias   xml 根節點名稱（根節點名與類名不一致時）
     * @param xml
     * @param clazz
     * @return
     */
    public final static <T> T fromXML(String alias, String xml, Class<T> clazz){
        if(clazz != null && !xml.equals("")){
            XStream xs = new XStream();
            XStream.setupDefaultSecurity(xs);
            xs.allowTypes(new Class[]{clazz});
            xs.ignoreUnknownElements();
            xs.alias(alias, clazz);
            xs.registerConverter(new MapEntryConverter());
            xs.autodetectAnnotations(true);
            
            return (T)xs.fromXML(xml);
        }
        
        return null;
    }
    
}

例程：

PhoneDeviceInformation info = XStreamFactory.fromXML(xml, PhoneDeviceInformation.class);//xml轉pojo

Map<String, Object> datas = XStreamFactory.fromXML("NetworkConfiguration", xml, Map.class);//xml轉map

PhoneDeviceInformation xml:

<DeviceInformation>
<serviceMode>On-premise</serviceMode>
<serviceDomain/>
<serviceState>Idle</serviceState>
<MACAddress>CC5A535E0DF0</MACAddress>
<HostName>SEPCC5A535E0DF0</HostName>
</DeviceInformation>

NetworkConfiguration xml:

<NetworkConfiguration>
<MACAddress>CC5A535E0DF0</MACAddress>
<HostName>SEPCC5A535E0DF0</HostName>
<ServiceMode>On-premise</ServiceMode>
</NetworkConfiguration>
