加入SAAJ和JAXB

我正在创建一个带有轴的Web服务。我使用的是SAAJ,JAXB和Servlet。我可以正确地使用JAXB对一个班级进行编组和解组。但是我如何一起使用SAAJ和JAXB进行SOAP通信。我想把JAXB转换的xml文本放到带有SAAJ的SOAP BODY标签中。我怎样才能做到这一点?我阅读了Oracle网站上的SAAJ文档,但这是不可理解的。他们说得太复杂了。

您可以执行以下操作:

<强>演示

SOAPBody实现了org.w3c.dom.Node,因此你可以让你的JAXB实现编组:

import javax.xml.bind.*;
import javax.xml.soap.*;

public class Demo {

    public static void main(String[] args) throws Exception {
        MessageFactory mf = MessageFactory.newInstance();
        SOAPMessage message = mf.createMessage();
        SOAPBody body = message.getSOAPBody();

        Foo foo = new Foo();
        foo.setBar("Hello World");

        JAXBContext jc = JAXBContext.newInstance(Foo.class);
        Marshaller marshaller = jc.createMarshaller();
        marshaller.marshal(foo, body);

        message.saveChanges();
        message.writeTo(System.out);
    }

}

Java模型(Foo)

下面是我们将用于此示例的简单Java模型:

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
public class Foo {

    private String bar;

    public String getBar() {
        return bar;
    }

    public void setBar(String bar) {
        this.bar = bar;
    }

}

<强>输出

以下是运行演示代码的输出(我已将其格式化为我的答案,以便于阅读)。

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
    <SOAP-ENV:Header />
    <SOAP-ENV:Body>
        <foo>
            <bar>Hello World</bar>
        </foo>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

<强>更新

以下是使用JAXB和JAX-WS API的示例(有关服务的详细信息,请参阅:http://blog.bdoughan.com/2013/02/leveraging-moxy-in-your-web-service-via.html)。

import javax.xml.bind.JAXBContext;
import javax.xml.namespace.QName;
import javax.xml.ws.Dispatch;
import javax.xml.ws.Service;
import javax.xml.ws.soap.SOAPBinding;
import blog.jaxws.provider.*;

public class Demo {

    public static void main(String[] args) throws Exception {
        QName serviceName = new QName("http://service.jaxws.blog/", "FindCustomerService");
        Service service = Service.create(serviceName);
        QName portQName = new QName("http://example.org", "SimplePort");
        service.addPort(portQName, SOAPBinding.SOAP11HTTP_BINDING, "http://localhost:8080/Provider/FindCustomerService?wsdl");

        JAXBContext jc = JAXBContext.newInstance(FindCustomerRequest.class, FindCustomerResponse.class);
        Dispatch<Object> sourceDispatch = service.createDispatch(portQName, jc, Service.Mode.PAYLOAD);
        FindCustomerRequest request = new FindCustomerRequest();
        FindCustomerResponse response = (FindCustomerResponse) sourceDispatch.invoke(request);
        System.out.println(response.getValue().getFirstName());
    }

}
