用maven创建基于wink的rest服务-传送文件(字符串和字节数组)(一)

Apache Wink是一个用于帮助开发者快速高效的开发RESTful Web services服务的java框架,他包括一个服务器端模块和一个客户端模块.
1.创建基于wink的web服务.
  a.用maven构建rest服务器端项目,直接看代码pom.xml.
  b.将cmd窗口切换到rest-server目录下执行mvn eclipse:myeclipse-clean eclipse:myeclipse命令下载pom.xml文件中配置的类库.
  c.在web.xml中将所有rest服务映射到RestServerApplication中,rest通过Application管理所有服务,直接看代码RestServerApplication.

  d.创建rest服务,直接看代码RestServerService.

<span style="font-size:12px;">package com.iluck.rest.server;/** * @author IluckySi * @date 20140528 */public class RestServerServiceImpl implements RestServerService {private static RestServerServiceImpl instance = null;;public synchronized static RestServerServiceImpl getInstance() {if(instance == null) {instance = new RestServerServiceImpl();}return instance;}public String upload(String message) {System.out.println(message);return "success";}public String upload(byte[] bytes) {System.out.println(new String(bytes));return "success";}}/*输出结果:我是司冬雪123sdx我是司冬雪123sdxw速度速度123sdxw速度速度123sdx*/</span>

2.创建基于wink的java客户端.
  a.用maven构建rest客户端项目,直接看代码pom.xml.
  b.将cmd窗口切换到rest-client目录下执行mvn eclipse:myeclipse-clean eclipse:myeclipse命令下载pom.xml文件中配置的类库.

  c.创建rest客户端,直接看代码RestClientService.

<span style="font-size:12px;">package com.ilucky.rest.client;import java.io.BufferedInputStream;import java.io.BufferedReader;import java.io.ByteArrayOutputStream;import java.io.File;import java.io.FileInputStream;import java.io.FileReader;import java.io.InputStream;import org.apache.wink.client.ClientResponse;import org.apache.wink.client.Resource;import org.apache.wink.client.RestClient;/** * @author IluckySi * @date 20140528 */public class RestClientService {public static void main(String[] args)  {try {RestClient restClient = new RestClient();        Resource resource = restClient.resource("http://127.0.0.1:8080/rest-server/rest/file/upload");        //传输字符串.        String message = "我是司冬雪123sdx";        final ClientResponse response1 =  resource.post(message);        System.out.println(response1.getEntity(String.class));        //传输二进制数.        byte[] bytes = message.getBytes("UTF-8");        final ClientResponse response2 =  resource.post(bytes);        System.out.println(response2.getEntity(String.class));        //用字节流从本地读取文件,将文件内容转换为二进制数传输.        File file = new File("E:/client2.txt");        byte[] bytes2 = new byte[(int) file.length()];        InputStream is = new FileInputStream(file);         BufferedInputStream bis = new BufferedInputStream(is);        ByteArrayOutputStream bytestream = new ByteArrayOutputStream();         byte[] b = new byte[2048];         int length;         length = bis.read(b);         while (length != -1) {         bytestream.write(b, 0, length);         length = bis.read(b);         } bis.close();        is.close();        bytestream.close();        bytes2 = bytestream.toByteArray();         final ClientResponse response3 =  resource.post(bytes2);        System.out.println(response3.getEntity(String.class));        //用字符流从本地读取文件,将文件内容转换为字符串传输.        StringBuffer sb = new StringBuffer();        FileReader fileReader = new FileReader(file);        BufferedReader bufferedReader = new BufferedReader(fileReader);        String line = bufferedReader.readLine();        while (line != null) {        sb.append(line + "\r\n");        line = bufferedReader.readLine();        }        final ClientResponse response4 =  resource.post(sb.toString());    System.out.println(response4.getEntity(String.class));    //注意：上述两种情况可能出现乱码,原因是txt文件采用的是系统默认编码方式ANSI,只需要将其另存并同时将编码方式改为UTF-8就可以了.} catch (Exception e) {e.printStackTrace();} }}/*输出结果:successsuccesssuccesssuccess*/</span>
