Question

我想从下面的肥皂响应中获取AddResult的值，即100：

<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><AddResponse xmlns="http://tempuri.org/"><AddResult>100</AddResult></AddResponse></soap:Body></soap:Envelope>

下面是Java代码：

package com.learncamel.routes.xmlxstream;

import java.util.HashMap;
import java.util.Map;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.dataformat.xstream.XStreamDataFormat;

import com.learncamel.domain.AddResponse;

public class XmlResponseToObject extends RouteBuilder{

    @Override
    public void configure() throws Exception {
        // TODO Auto-generated method stub
        Map<String, String> reference = new HashMap<String, String>();
        reference.put("AddResponse ", AddResponse.class.getName());

        XStreamDataFormat xstreamDataFormat = new XStreamDataFormat();
        xstreamDataFormat.setAliases(reference);
        xstreamDataFormat.setPermissions(AddResponse.class.getName());

        try { 
            from("direct:xmlinput")
            .log("Received Message before unmarshal is ${body} and Headers are ${headers}")
            .unmarshal(xstreamDataFormat)
            .log("Received Message after unmarshal is ${body} and Headers are ${headers}")
            .to("log:?level=INFO&showBody=true");
       } catch(Exception e) {
            e.printStackTrace();
       }       
    }
}

下面是junit代码：

package com.learncamel.routes.xmlxstream;

import org.apache.camel.RoutesBuilder;
import org.apache.camel.test.junit4.CamelTestSupport;
import org.junit.Test;

public class XmlResponseToObjectTest extends CamelTestSupport {

    @Override
    public RoutesBuilder createRouteBuilder() throws Exception {
        return new XmlResponseToObject();       
    }   

    @Test
    public void unMarshalTest() throws InterruptedException{
        //AddResponse addresponse=new AddResponse();
        String input="<?xml version=\"1.0\" encoding=\"utf-8\"?><soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\"><soap:Body><AddResponse xmlns=\"http://tempuri.org/\"><AddResult>100</AddResult></AddResponse></soap:Body></soap:Envelope>";
        template.sendBody("direct:xmlinput",input);
    }
}

下面是POJO：

package com.learncamel.domain;



public class AddResponse {

    private String AddResult;

    public String getAddResult() {
        return AddResult;
    }

    public void setAddResult(String addResult) {
        AddResult = addResult;
    }
}

Answer 1

您可以尝试使用xpath从xml中提取值，例如：

 .convertBodyTo(org.w3c.dom.Document.class)
 .setProperty("needValue",xpath("*//AddResult/text()",String.class))
  //use extracted value

如果您需要将输入xml转换为xslt组件的另一种外观。

更新：如果您确实需要使用对象来删除异常，则需要提取映射的主体AddResponse，因为您已对其进行了映射。您的输入字符串从未映射的肥皂元素“信封”开始。如果.unmarshall（）之前有CxfPayload，只需将其转换为Document或String。为了成功进行测试，只需除去肥皂成分。

Answer 2

public static Document loadXMLString(String response) throws Exception
{
    DocumentBuilderFactory dbf =DocumentBuilderFactory.newInstance();
    DocumentBuilder db = dbf.newDocumentBuilder();
    InputSource is = new InputSource(new StringReader(response));

    return db.parse(is);
}

public static List<String> getFullNameFromXml(String response, String tagName) throws Exception {
    Document xmlDoc = loadXMLString(response);
    NodeList nodeList = xmlDoc.getElementsByTagName(tagName);
    List<String> ids = new ArrayList<String>(nodeList.getLength());
    for(int i=0;i<nodeList.getLength(); i++) {
        Node x = nodeList.item(i);
        ids.add(x.getFirstChild().getNodeValue());             
        System.out.println(nodeList.item(i).getFirstChild().getNodeValue());
    }
    return ids;
}

public static void main(String arg[]) throws Exception
{

    String res="<?xml version=\"1.0\" encoding=\"utf-8\"?><soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\"><soap:Body><SubtractResponse xmlns=\"http://tempuri.org/\"><SubtractResult>150</SubtractResult></SubtractResponse></soap:Body></soap:Envelope>";
    List<String> output = XmlResponseToObject.getFullNameFromXml(res, "SubtractResult");
    String[] strarray = new String[output.size()];
    output.toArray(strarray);
    String x = output.get(0);
    System.out.println(x);
}
