webservice传输大文件
server端：(根据需求写)
接口：
public interface MyFile {
public DataHandler downFile(String type , String id);
}
实现类：
public class MyFileImpl implements MyFile {
public DataHandler downFile(String fileName,String id) {
Properties p = new Properties();
String path=id+".xml";
File file = null;
try {
p.load(MyFileImpl.class.getResourceAsStream("/parameter.properties"));
} catch (IOException e) {
e.printStackTrace();
}
if(fileName.equals("0")){
file = new File(p.getProperty("0"),p.getProperty("f0"));
}
if (fileName.equals("1")) {
file = new File(p.getProperty("1"),path);
} else if(fileName.equals("2")) {
file = new File(p.getProperty("2"),p.getProperty("f2"));
}else if(fileName.equals("3")){
file = new File(p.getProperty("3"),p.getProperty("f3"));
}
DataHandler dh= new DataHandler(new FileDataSource(file));
return dh;
}
}
配置services.xml(位置在src/META-INF/xfire下的service.xml)
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://xfire.codehaus.org/config/1.0"> <service> <name>FileService</name> <serviceClass>org.file.service.MyFile</serviceClass> <implementationClass> org.file.service.MyFileImpl </implementationClass> <properties> <property key="mtom-enabled">true</property> </properties> </service> </beans>
web.xml配置
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

测试客户端：
public class MyTest {
public static void main(String[] args) {
Service serviceModle = new ObjectServiceFactory().create(MyFile.class,
"FileService", "http://service.file.org/FileService", null);
MyFile service = null;
try {
service = (MyFile) new XFireProxyFactory().create(serviceModle,
"http://192.168.3.67:8080/MyFile/services/FileService");
Client client = Client.getInstance(service);
client.setProperty("mtom-enabled", "true");
client.setProperty(HttpTransport.CHUNKING_ENABLED, "true");
} catch (MalformedURLException e) {
e.printStackTrace();
}
String fileName="3";
System.out.println("开始传输");
File file1 = new File("F://", "1dsa.txt");
DataHandler dhl = service.downFile(fileName,null);
try {
InputStream in = dhl.getInputStream();
FileOutputStream out = new FileOutputStream(file1);
file1.createNewFile();
byte[] buff = new byte[1024 * 1024];
int len = -1;
while (-1 != (len = in.read(buff, 0, buff.length))) {
out.write(buff, 0, len);
}
in.close();
out.flush();
out.close();
System.out.println("传输完毕");
} catch (IOException e) {
e.printStackTrace();
}
}
}
注意项目中要加入的jar包
如果运行客户端报错; javax.xml.stream.FactoryConfigurationError: Provider com.bea.xml.stream.MXParserFactory not found和Exception in thread "main" org.codehaus.xfire.XFireRuntimeException: Could not invoke service.. Nested exception is org.codehaus.xfire.fault.XFireFault: Fault: java.lang.NullPointerException
org.codehaus.xfire.fault.XFireFault: Fault: java.lang.NullPointerException
看过论坛上有很多帖子对于这个错误都没有解决办法，那我在这里悄悄的告诉你，少包了。少下面这2个包（红框圈住的） 导入这2个包就OK了
