Web Service中Axis与DotNet互操作最佳实践：传递java.util.Map对象给C#(译)

由于Axis支持自动序列化和反序列化JavaBean，实现了Java对象和XML SOAP消息映射，所以将Java的Map对象传递到.NET最简单的方法是实现一个JavaBean数组对象：

File 1:

public class MapEntryVO {

private Object key;

private Object value;

public MapEntryVO() {

}

public MapEntryVO(Object key, Object value) {

this.key = key;

this.value = value;

}

public Object getKey() {

return key;

}

public void setKey(Object value) {

key = value;

}

public Object getValue() {

return value;

}

public void setValue(Object value) {

this.value = value;

}

}

File 2:

import java.util.*;

public class WebServicesUtils {

public static MapEntryVO[] convertMapToMapEntryVO(Map conv) {

MapEntryVO[] result = new MapEntryVO[conv.size()];

int i = 0;

Iterator iter = conv.entrySet().iterator();

while (iter.hasNext()) {

Map.Entry item = (Map.Entry) iter.next();

result[i++] = new MapEntryVO(item.getKey(),item.getValue());

}

return result;

}

}

File 3:

// Example WebService

public class TestService {

public MapEntryVO[] testMethod() {

java.util.Map value = new java.util.HashMap();

value.put("Key 1","Value 1");

value.put("Key 2","Value 2");

return WebServicesUtils.convertMapToMapEntryVO(value);

}

}

代码完成后，记得在server-config.wsdd(或部署文件deploy.wsdd)中配置JavaBean的序列化，通知Axis你需要自动序列化的对象：

<typeMapping qname="java:MapEntryVOList"

type="java:MapEntryVO[]"

serializer="org.apache.axis.encoding.ser.ArraySerializerFactory"

deserializer="org.apache.axis.encoding.ser.ArrayDeserializerFactory"

encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" />

<typeMapping qname="java:MapEntryVO"

type="java:MapEntryVO"

serializer="org.apache.axis.encoding.ser.BeanSerializerFactory"

deserializer="org.apache.axis.encoding.ser.BeanDeserializerFactory"

encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" />
