java 中HttpClient傳輸xml字符串實(shí)例詳解

介紹：我現(xiàn)在有一個(gè)對(duì)象page，需要將page對(duì)象轉(zhuǎn)換為xml格式并以binary方式傳輸?shù)椒?wù)端

其中涉及到的技術(shù)點(diǎn)有：

1、對(duì)象轉(zhuǎn)xml流
2、輸出流轉(zhuǎn)輸入流
3、httpClient發(fā)送二進(jìn)制流數(shù)據(jù)

POM文件依賴(lài)配置

java代碼示例

public void testNewPage() throws Exception{ 
    //定義對(duì)象 
    Page page =new Page(); 
    page.setTitle("testPage"); 
    page.setSyntax("xwiki/2.0"); 
    page.setContent("This is a testPage"); 
    page.setId("xwiki:Main.testPage"); 
    //初始化并轉(zhuǎn)換對(duì)象為xml文件的流 
    JAXBContext context = JAXBContext.newInstance("org.xwiki.rest.model.jaxb"); 
    Marshaller marshaller=context.createMarshaller(); 
    Unmarshaller unmarshaller = context.createUnmarshaller(); 
    ByteArrayOutputStream out = new ByteArrayOutputStream(); 
    marshaller.marshal( page, out ); 
    //將流轉(zhuǎn)換并放入到InputStreamEntity中 
    InputStreamEntity inputStreamEntity=new InputStreamEntity(new ByteArrayInputStream(out.toByteArray())); 
 
    //發(fā)送請(qǐng)求 
    CloseableHttpClient httpclient = HttpClients.createDefault(); 
    HttpUriRequest httpPost = RequestBuilder.put() 
        .setUri(new URI("http://172.16.200.220:8082/xwiki/rest/wikis/xwiki/spaces/Main/pages/testPage")) 
        .setEntity(inputStreamEntity) 
        .setHeader("Content-Type", "application/xml") 
        .setHeader("Cookie", cookieStr).build(); 
    //獲取返回結(jié)果 
    CloseableHttpResponse response = httpclient.execute(httpPost); 
    System.out.println(response.getStatusLine().getStatusCode()); 
    HttpEntity responseEntity=response.getEntity(); 
    System.out.println(responseEntity); 
    if(response.getStatusLine().getStatusCode()<400){ 
      Page responsePage = (Page) unmarshaller.unmarshal(responseEntity.getContent()); 
      System.out.println(responsePage); 
//      System.out.println(new Gson().toJson(responsePage)); 
    } 
  }
