CXF之MTOM(传送二进制数据文件)实例

服务接口：

package cxf.server; import javax.jws.WebService; @WebService public interface 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") public class 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 = new byte[100000]; int bytesRead = 0; while ((bytesRead = is.read(b)) != -1) { os.write(b,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) public class Picture { @XmlMimeType("application/octet-stream") private DataHandler imag; public DataHandler getImag() { return imag; } public void setImag(DataHandler imag) { this.imag = imag; } } ?

?

服务端配置：

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="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"> <import resource="classpath:META-INF/cxf/cxf.xml" /> <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" /> <import resource="classpath:META-INF/cxf/cxf-servlet.xml" /> <jaxws:endpoint id="SendPicture" implementor="cxf.server.SendPictureImpl" address="/SendPicture"> <jaxws:properties> <entry key="mtom-enabled" value="true" /> </jaxws:properties> </jaxws:endpoint> </beans> ?

?

客户端配置：

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="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:client id="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; public final class Client { public static void 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>
