CXF之MTOM(传送二进制数据文件)实例

http://blog.csdn.net/fhd001/article/details/5789406

服务接口：

package cxf.server;
import javax.jws.WebService;
@WebService
publicinterface SendPicture {
    String sendPicture(Picture picture);
}

服务实现：

package cxf.server;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import javax.activation.DataHandler;
import javax.jws.WebService;
@WebService(endpointInterface = "cxf.server.SendPicture")
publicclass SendPictureImpl implements SendPicture {
@Override
public String sendPicture(Picture picture) {

try {
            DataHandler handler = picture.getImag();
            InputStream is = handler.getInputStream();
            OutputStream os = new FileOutputStream(new File("D://8.gif"));
byte[] b = newbyte[100000];
int bytesRead = 0;
while ((bytesRead = is.read(b)) != -1) {
                os.write(b, 0, bytesRead);
            }
            os.flush();
            os.close();
            is.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
        System.out.println("server: " + "FHD");
return"YES";
    }
}

传输的数据对象，注意DataHandler这个属性：

package cxf.server;
import javax.activation.DataHandler;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlMimeType;
@XmlAccessorType(XmlAccessType.FIELD)
publicclass Picture {
@XmlMimeType("application/octet-stream")
private DataHandler imag;
public DataHandler getImag() {
return imag;
    }
publicvoid setImag(DataHandler imag) {
this.imag = imag;
    }
}

服务端配置：

<?xmlversion="1.0"encoding="UTF-8"?>
<beansxmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:jaxws="http://cxf.apache.org/jaxws"
xsi:schemaLocation="
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
    http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">
<importresource="classpath:META-INF/cxf/cxf.xml"/>
<importresource="classpath:META-INF/cxf/cxf-extension-soap.xml"/>
<importresource="classpath:META-INF/cxf/cxf-servlet.xml"/>
<jaxws:endpointid="SendPicture"implementor="cxf.server.SendPictureImpl"
address="/SendPicture">
<jaxws:properties>
<entrykey="mtom-enabled"value="true"/>
</jaxws:properties>
</jaxws:endpoint>
</beans>

客户端配置：

<?xmlversion="1.0"encoding="UTF-8"?>
<beansxmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:jaxws="http://cxf.apache.org/jaxws"
xsi:schemaLocation="
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
    http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">
<jaxws:clientid="client"
address="http://localhost:8085/java_first_spring_support1/service/SendPicture"
serviceClass="cxf.server.SendPicture"/>
</beans>

客户端调用：

package cxf.client;
import java.io.File;
import javax.activation.DataHandler;
import javax.activation.DataSource;
import javax.activation.FileDataSource;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import cxf.server.Picture;
import cxf.server.SendPicture;

publicfinalclass Client {
publicstaticvoid main(String args[]) throws Exception {

        ClassPathXmlApplicationContext context  = new ClassPathXmlApplicationContext(new String[] {"client-beans.xml"});
        SendPicture client = (SendPicture)context.getBean("client");

        Picture picture = new Picture();
        DataSource source = new FileDataSource(new File("F://3.gif"));
        picture.setImag(new DataHandler(source));
        String str = client.sendPicture(picture);
        System.out.println("client: " + str);
        System.exit(0);
    }
}

请注意：

@XmlMimeType("application/octet-stream")

private DataHandler imag;

还有：

<jaxws:properties>

<entry key="mtom-enabled" value="true" />

</jaxws:properties>
