webservice文件上传下载
使用DataHandler实现webservice的文件上传下载
服务端代码：
package com.hello.weChat.controller; import javax.activation.DataHandler; import javax.activation.FileDataSource; import java.io.File; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; /** * Created by winkey on 15-2-10. */ public class FileController { /* * 文件上传服务 */ public String upload(DataHandler handler, String fileName) { String fullPath = "F:\\test\\testupload\\" + fileName; File file = new File(fullPath); int flag = 0; if (handler == null) return "failure"; if (fileName == null) return "failure"; InputStream input = null; FileOutputStream fos = null; try { input = handler.getInputStream(); fos = new FileOutputStream(file); byte[] buffer = new byte[4096]; while ((flag = input.read(buffer)) != -1) { fos.write(buffer, 0, flag); } } catch (IOException e) { e.printStackTrace(); return "failure"; } finally { try { if (input != null) { input.close(); } if (fos != null) { fos.close(); } } catch (IOException e) { e.printStackTrace(); } } return "Success"; } /* * 文件下载服务 */ public DataHandler downloadFile() { String filepath = "F:\\test\\head.jpg"; DataHandler dataHandler = new DataHandler(new FileDataSource(filepath)); System.out.println("-------------------------下载"); return dataHandler; } }
服务端wsdd文件配置
<service name="FileController" provider="java:RPC"> <parameter name="className" value="com.hello.weChat.controller.FileController"/> <parameter name="allowedMethods" value="downloadFile,upload"/> <parameter name="scope" value="session"/> <operation name="upload" qname="operNS:upload" xmlns:operNS="upload" returnType="rns:string" xmlns:rns="http://www.w3.org/2001/XMLSchema"> <parameter name="handler" type="ns:DataHandler" xmlns:ns="http://www.w3.org/2001/XMLSchema"/> <parameter name="fileName" type="ns:string" xmlns:ns="http://www.w3.org/2001/XMLSchema"/> </operation> <typeMapping qname="hns:DataHandler" xmlns:hns="ns:FileHandler" languageSpecificType="java:javax.activation.DataHandler" serializer="org.apache.axis.encoding.ser.JAFDataHandlerSerializerFactory" deserializer="org.apache.axis.encoding.ser.JAFDataHandlerDeserializerFactory" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" /> </service>
下载的时候只需配置typeMapping，上传的时候需要同时配置operation和typeMaping
