Question

如下所示。对于String中的所有值，输出为<value>{val}</value>而不是<value><string>EXT</string></value>

HashMap parameterMap = new HashMap();
client.setTransportFactory(new CustomXmlRpcCommonsTransportFactory(client));
client.setConfig(config);
parameterMap.put("hostName", "EXT");
parameterMap.put("externalData1", "EXEMPLE");
parameterMap.put("originTimeStamp", new Date());
parameterMap.put("subscriberNumberNAI", 2);
parameterMap.put("subscriberNumber", "278980890");
ArrayList params = new ArrayList();
params.add(parameterMap);
client.executeAsync("Methode", params, callback);

还有我的输出

<?xml version="1.0" encoding="UTF-8"?>
<methodCall>
    <methodName>GetBalanceAndDate</methodName>
    <params>
        <param>
            <value>
                <struct>
                    <member>
                        <name>subscriberNumberNAI</name>
                        <value>
                            <i4>2</i4>
                        </value>
                    </member>
                    <member>
                        <name>hostName</name>
                        <value>EXT</value>
                    </member>
                    <member>
                        <name>subscriberNumber</name>
                        <value>278980890</value>
                    </member>
                        <name>originTimeStamp</name>
                        <value>
                            <dateTime.iso8601>20150912T08:50:04</dateTime.iso8601>
                        </value>
                    </member>
                    <member>
                        <name>externalData1</name>
                        <value>EXEMPLE</value>
                    </member>
                </struct>
            </value>
        </param>
    </params>
</methodCall>

Answer 1

根据XML-RPC Data types，字符串可以是

<string>Hello world!</string>

或只是

Hello world!

<string>标记是可选的。

Answer 2

Apache XML-RPC is sending strings as <value>SomeString</value>.
Whereas I would expect <value><string>SomeString</string></value>.

两种格式均有效。兼容XML-RPC的软件（就像Apache XML-RPC一样）必须能够理解两者。当然，您只能生产一个。不幸的是，那里有很多处理器，它们只能理解一个。

幸运的是，更改Apache XML-RPC生成的格式并不是很困难。首先，创建一个自定义类型工厂：

package mypackage;

import org.apache.xmlrpc.common.TypeFactoryImpl;
import org.apache.xmlrpc.common.XmlRpcController;
import org.apache.xmlrpc.common.XmlRpcStreamConfig;
import org.xml.sax.ContentHandler;
import org.xml.sax.SAXException;

public class MyTypeFactory extends TypeFactoryImpl {
    private static final TypeSerializer myStringSerializer = new StringSerializer(){
        public void write(ContentHandler pHandler, Object pObject) throws SAXException {
            write(pHandler, STRING_TAG, pObject.toString());
        }
    };

    public MyTypeFactory(XmlRpcController pController) {
        super(pController);
    }

    public TypeSerializer getSerializer(XmlRpcStreamConfig pConfig,
            Object pObject) throws SAXException {
        if (pObject instanceof String) {
            return myStringSerializer;
        }
        return super.getSerializer(pConfig, pObject);
    }

}

然后，您必须安装该自定义类型的工厂。可以按照“自定义数据类型”一节中的说明进行操作：http://ws.apache.org/xmlrpc/advanced.html
