你好我想申请似乎很简单,但我不知道怎么了,需要一些澄清。 这里是情景:我想调用Web服务方法,这个方法的名字是找到(),并接受作为参数的对象,该对象代表组成的主键,由两个字符串ID和类型组成。 对象 - 其在肥皂主密钥 - 表示为:
<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>
我的第一个想法是约从HTTP POST请求来创建一个java变压器,其调用主键类构造想主键对象中读取两个ARGS(id和类型),则所创建的对象传递给皂组分,以穿心莲基于对象上的SOAP请求,然后调用与HTTP组件web服务和最后写入的响应到文件中。 此产生的流量:
<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>
我的定制变压器
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;
}
}
当我运行该项目,我得到的错误

我不知道如果我的逻辑是错误的,或者如果有,把工作做了一个简单的方法? thak你的帮助。
