CXF-webService实现文件上传下载
本文直接采用CXF+spring完成的一个支持上传文件的demo，包括视频、音频等，示例简单仅供参考。下面直接上代码：
一、首先进行服务端搭建（CXF+Spring）:
1、新建web工程（示例为CXFServer）
2、导入所需的jar包，示例工程采用cxf3.0 可到官网上下载或者到 http://download.csdn.net/detail/erris/9370346 下载，本人较懒，就将lib下jar包全部导入，省事操作。
3工程结构
4、web.xml配置
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>CXFServer</display-name> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:beans.xml</param-value> </context-param> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:cxf-servlet.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <servlet> <servlet-name>cxf</servlet-name> <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class> <init-param> <param-name>config-location</param-name> <param-value>classpath:cxf-servlet.xml</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>cxf</servlet-name> <url-pattern>/cxf/*</url-pattern> </servlet-mapping> </web-app>
5、Iservice接口。
@WebService
@BindingType(value=SOAPBinding.SOAP12HTTP_BINDING)
public interface IService {
@WebMethod(operationName = "download")
public FileSources download(@WebParam(name="fileName")String fileName);
@WebMethod(operationName = "upload")
public String upload(@WebParam(name="file")FileSources file);
6、IService实现类
@WebService(endpointInterface = "com.git.service.IService")
public class ServiceImpl implements IService{
@Override
public String upload(FileSources file) {
DataHandler handler = file.getHandler();
InputStream is = null;
OutputStream os = null;
try {
System.out.println("文件开始上传。。。。。。");
is = handler.getInputStream();
os = new FileOutputStream("F:/" + file.getFileName() + "."
+ file.getContentType());
int n = 0;
byte[] b = new byte[1024];
while ((n = is.read(b)) != -1) {
os.write(b, 0, n);
}
os.flush();
System.out.println("文件上传成功~");
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
if (is != null) {
is.close();
}
if (os != null) {
os.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
return "上传成功！";
}
@Override
public FileSources download(String fileName) {
FileSources file =new FileSources();
String url ="f:/"+fileName+".jpg";
file.setFileName(fileName);
file.setContentType("jpg");
try {
DataSource ds = new FileDataSource(new File(url));
file.setHandler(new DataHandler(ds));
return file;
} catch (Exception e) {
return null;
}
}
7、文件实体类（省略setter和getter方法）
@XmlRootElement(name="FileSources")
@XmlAccessorType(XmlAccessType.FIELD)
@XmlSeeAlso({FileSources.class})
public class FileSources implements Serializable{
private static final long serialVersionUID = -5236565563763834569L;
private int id;
private String fileName;// 文件名
private String contentType;// 文件类型
private DataHandler handler;//大型文件上传所需
8、在cxf-servlet.xml中进行配置
<?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-servlet.xml" /> <bean id="hello" class="com.git.service.impl.ServiceImpl" /> <!-- 加载提供的服务 --> <jaxws:endpoint id="service" address="/service" implementor="#hello"> <!-- 配置拦截器 --> <jaxws:inInterceptors> <bean class="org.apache.cxf.interceptor.LoggingInInterceptor" /> </jaxws:inInterceptors> <jaxws:outInterceptors> <bean class="org.apache.cxf.interceptor.LoggingOutInterceptor" /> </jaxws:outInterceptors> </jaxws:endpoint> </beans>到此服务端代码都完成了，将工程部署到tomcat中，在浏览器中输入http://localhost:8080/CXFServer/cxf/service?wsdl
二、客户端（CXFClient）
客户端采用web工程，结构为：
2、IServer和JavaBean 都和服务端一样。
3、Spring配置文件配置
<?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:p="http://www.springframework.org/schema/p"
xmlns:jaxws="http://cxf.apache.org/jaxws" xmlns:cxf="http://cxf.apache.org/core"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://cxf.apache.org/jaxws
http://cxf.apache.org/schema/jaxws.xsd">
<bean id="client" class="com.git.service.IService"
factory-bean="clientFactory" factory-method="create" />
<bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">
<property name="serviceClass" value="com.git.service.IService" />
<property name="address" value="http://localhost:8080/CXFServer/cxf/service" />
</bean>
</beans>
4、测试类
ApplicationContext ctx = new ClassPathXmlApplicationContext(
"applicationContext.xml");
// --------------------------[上传]----------------------------
FileSources fs = new FileSources();
fs.setFileName("3");
fs.setContentType("avi");
//加载文件
DataSource source = new FileDataSource(new File("d:\\3.avi"));
fs.setHandler(new DataHandler(source));
IService client = (IService) ctx.getBean("client");
try {
String result = client.upload(fs); // 此处不能传一个空对象,否则会出错
System.out.println(result);
System.out.println("结果：" + result);
} catch (Exception e) {
System.out.println("请选择文件！\n");
System.out.println("抛出异常为" + e.getMessage());
}
// --------------------------【END】------------------------到此
到此客户端编写结束，将服务端和客户端部署到tomcat，启动，执行客户端测试类，可实现上传。路径什么根据自己情况改一下。
这只是一个学习型的demo，代码什么都比较简单，仅供参考~谢谢
