本文提供了使用Java的HttpClient库发送GET和POST请求的具体示例代码，演示了如何构造请求、设置参数并获取服务器响应。

Get方式：

String url="http://localhost:8080/HttpClientDemo/test";
		HttpGet httpRequest=new HttpGet(url);
		
		HttpClient httpClient=new DefaultHttpClient();
		HttpResponse response=httpClient.execute(httpRequest);
		if(response.getStatusLine().getStatusCode()==HttpStatus.SC_OK){
			String result=EntityUtils.toString(response.getEntity());
			System.out.println(result);
		}

Post方式：

String url="http://localhost:8080/HttpClientDemo/test";
		HttpPost request=new HttpPost(url);
		List<NameValuePair> params=new ArrayList<NameValuePair>();
		params.add(new BasicNameValuePair("name", "testname"));
		HttpEntity httpEntity=new UrlEncodedFormEntity(params,"utf-8");
		request.setEntity(httpEntity);
		HttpClient httpClient=new DefaultHttpClient();
		HttpResponse response=httpClient.execute(request);
		if(response.getStatusLine().getStatusCode()==HttpStatus.SC_OK){
			String result=EntityUtils.toString(response.getEntity());
			System.out.println(result);
		}
