本文详细介绍了如何使用Java中的HttpClient库来发送HTTP GET请求，并从响应中读取JSON格式的数据。通过实例展示了设置URI、处理中文乱码及读取响应内容的完整过程。

        BufferedReader in = null;
		String content = null;
		try {
			// 定义HttpClient
			HttpClient client = new DefaultHttpClient();

			// 实例化HTTP方法
			HttpGet request = new HttpGet();
			//拼接接口
			request.setURI(new URI("HTTPclient的地址"));
			HttpResponse response = client.execute(request);
			//中文乱码问题
			response.addHeader("Content-Type","application/json;charset=UTF-8");
			in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
			StringBuffer sb = new StringBuffer("");
			String line = "";
			String NL = System.getProperty("line.separator");
			while ((line = in.readLine()) != null) {
				sb.append(line + NL);
			}
			in.close();
			content = sb.toString();
		} finally {
			if (in != null) {
				try {
					in.close();// 最后要关闭BufferedReader
				} catch (Exception e) {
					e.printStackTrace();
				}
			}

			return content;
		}
