CXF：通過WebService上傳檔案，包括大檔案的處理，cxfwebservice

參考網上文章，用CXF發布上傳檔案介面，並上傳大檔案的測試。

架構：spring3.1+cxf2.7.6

1.定義檔案類實體

import javax.activation.DataHandler;import javax.xml.bind.annotation.XmlMimeType;/** * CXF上傳和下載檔案對象封裝類 由於CXF的DataHandler無法擷取檔案名稱和檔案類型，需要在上傳和下載時附帶檔案名稱 *  */public class CxfFileWrapper {    // 檔案名稱    private String fileName = null;    // 副檔名    private String fileExtension = null;    // 檔案位元據    private DataHandler file = null;    public final String getFileName() {        return fileName;    }    public final void setFileName(String fileName) {        this.fileName = fileName;    }    public final String getFileExtension() {        return fileExtension;    }    public final void setFileExtension(String fileExtension) {        this.fileExtension = fileExtension;    }    // 註解該欄位為二進位流    @XmlMimeType("application/octet-stream")    public final DataHandler getFile() {        return file;    }    public final void setFile(DataHandler file) {        this.file = file;    }}

2.定義服務介面

import javax.jws.WebMethod;import javax.jws.WebParam;import javax.jws.WebService;import net.bwda.domain.upload.CxfFileWrapper;@WebService(name = "FileWS", serviceName = "FileWS")public interface FileWS {    /**     * 檔案上傳     * @param file 檔案上傳封裝類     * @return 上傳成功返回true，上傳失敗返回false。     */    @WebMethod    boolean upload(@WebParam(name = "file") CxfFileWrapper file);    /**     * 檔案下載     * @return 檔案     */    @WebMethod    CxfFileWrapper download();}import java.io.BufferedOutputStream;import java.io.File;import java.io.FileOutputStream;import java.io.InputStream;import java.io.OutputStream;import javax.activation.DataHandler;import javax.activation.DataSource;import javax.activation.FileDataSource;import org.springframework.stereotype.Component;import org.springframework.stereotype.Service;import net.bwda.domain.upload.CxfFileWrapper;import net.bwda.service.upload.FileWS;@Service@Component("fileWS")public class FileWSImpl implements FileWS {    public boolean upload(CxfFileWrapper file){        boolean result = true;        OutputStream os = null;        InputStream is = null;        BufferedOutputStream bos = null;        try {            is = file.getFile().getInputStream();            File dest = new File("d:\\upload\\" + file.getFileName());            os = new FileOutputStream(dest);            bos = new BufferedOutputStream(os);            byte[] buffer = new byte[1024*1024];            int len = 0;            while ((len = is.read(buffer)) != -1) {                bos.write(buffer, 0, len);            }            bos.flush();        } catch (Exception e) {            e.printStackTrace();            result = false;        } finally {            if(bos != null){                try{                    bos.close();                }catch(Exception e){                                    }            }            if(os != null){                try{                    os.close();                }catch(Exception e){                                    }            }            if(is != null){                try{                    is.close();                }catch(Exception e){                                    }            }        }        return result;    }    public CxfFileWrapper download() {        //下載檔案的路徑         String filePath = "D:\\test.xlsx";        CxfFileWrapper fileWrapper = new CxfFileWrapper();        fileWrapper.setFileName("test.xlsx");        fileWrapper.setFileExtension("xlsx");        DataSource source = new FileDataSource(new File(filePath));        fileWrapper.setFile(new DataHandler(source));        return fileWrapper;    }}

3.定義CXF設定檔

<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://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsdhttp://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd"    xmlns:cxf="http://cxf.apache.org/core">    <import resource="classpath:META-INF/cxf/cxf.xml" />    <import resource="classpath:META-INF/cxf/cxf-servlet.xml" />    <cxf:bus>        <cxf:properties>            <!-- 定義上傳檔案的最大長度，限制為256M -->            <entry key="org.apache.cxf.stax.maxTextLength" value="268435456" />        </cxf:properties>    </cxf:bus>    <jaxws:endpoint id="fileWSEndpoint" implementor="#fileWS"        address="/file">        <jaxws:properties>            <!-- 開啟MTOM -->            <entry key="mtom_enabled" value="true"></entry>        </jaxws:properties>    </jaxws:endpoint></beans>

4.產生用戶端代碼

d:\apache-cxf-2.7.6\bin\wsdl2java.bat -frontend jaxws21 -p com..test.webservice.file -client http://localhost:9080/filemark/webservice/file?wsdl

5.根據自動上傳的代碼上傳檔案測試

/** * Please modify this class to meet your needs * This class is not complete */import java.io.File;import java.net.URL;import javax.activation.DataHandler;import javax.activation.DataSource;import javax.activation.FileDataSource;import javax.xml.namespace.QName;/** * This class was generated by Apache CXF 2.7.6 * 2016-11-10T18:37:44.270+08:00 * Generated source version: 2.7.6 *  */public final class FileWS_FileWSImplPort_Client {    private static final QName SERVICE_NAME = new QName("http://upload.serviceimpl.bwda.net/", "FileWSImplService");    private FileWS_FileWSImplPort_Client() {    }    public static void main(String args[]) throws java.lang.Exception {        URL wsdlURL = FileWSImplService.WSDL_LOCATION;        FileWSImplService ss = new FileWSImplService(wsdlURL, SERVICE_NAME);        FileWS port = ss.getFileWSImplPort();                  {        System.out.println("Invoking upload...");        net.bwda.Test.webservice.CxfFileWrapper _upload_file = new CxfFileWrapper();        _upload_file.setFileName("test.csv");        _upload_file.setFileExtension("csv");        DataSource source = new FileDataSource(new File("d:\\test.csv"));        _upload_file.setFile(new DataHandler(source));        boolean _upload__return = port.upload(_upload_file);        System.out.println("upload.result=" + _upload__return);        }        System.exit(0);    }}
