Здравствуйте, то, что я хочу применить, кажется очень простым, но я не знаю, как это сделать, нужны некоторые разъяснения. вот сценарий: я хочу вызвать метод веб-службы, имя этого метода — find() и принять в качестве аргумента объект, объект представляет собой составной первичный ключ, состоящий из двух строк: идентификатора и типа. объект, который является первичным представлением ключа в мыле:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsd="http://wsdouane/">
<soapenv:Header/>
<soapenv:Body>
<wsd:find>
<entity>
<id>string_1</id>
<type>string_2</type>
</entity>
</wsd:find>
</soapenv:Body>
</soapenv:Envelope>
Моя первая идея заключалась в том, чтобы прочитать два аргумента (идентификатор и тип) из почтового запроса http, чтобы создать нужный объект первичного ключа с помощью java-преобразователя, который вызывает конструктор класса первичного ключа, а затем передать созданный объект мыльному компоненту для создайте запрос мыла на основе объекта, затем вызовите веб-службу с компонентом http и, наконец, запишите ответ в файл. это результирующий поток:
<flow name="testObjetFlow1" doc:name="testObjetFlow1">
<http:inbound-endpoint exchange-pattern="one-way" host="localhost" port="8088" doc:name="HTTP"/>
<custom-transformer class="com.test.transformer.HttpRequestToPrimaryKeyObject" doc:name="PK Object Transformer"/>
<cxf:jaxws-client operation="find" serviceClass="douane.Douane" port="douanePort" doc:name="SOAP"/>
<http:outbound-endpoint exchange-pattern="request-response" method="POST" address="http://localhost:8080/ClientsDB/douane" doc:name="douaneWS"/>
<mulexml:object-to-xml-transformer doc:name="Object to XML"/>
<file:outbound-endpoint path="C:\MuleStudio\SandBox\output" outputPattern="#[function:datestamp:dd-MM-yy]_#[function:systime].xml " responseTimeout="10000" doc:name="Outgoing File"/>
</flow>
Мой самодельный трансформер
package com.test.transformer;
import org.mule.api.MuleMessage;
import org.mule.api.transformer.TransformerException;
import org.mule.transformer.AbstractMessageTransformer;
import douane.DouanePK;
public class HttpRequestToPrimaryKeyObject extends AbstractMessageTransformer {
@Override
//DouanePK represent the primary key entity
public DouanePK transformMessage(MuleMessage message, String outputEncoding)
throws TransformerException {
// TODO Auto-generated method stub
String id = message.getInboundProperty("id");
String type = message.getInboundProperty("type");
DouanePK primKey = new DouanePK();
dp.setId(id);
dp.setType(type);
return primKey;
}
}
когда я запускаю проект, я получаю сообщение об ошибке

Я не знаю, то ли моя логика неверна, то ли есть простой способ выполнить работу? Спасибо за вашу помощь.
