每次用，每次查，每次查，每次忘，这下忘不了了吧！

另，要这两个包，

public void getResponseDetail(String url) {
		HttpServletResponse response = (HttpServletResponse) super.getContextParam(ServletActionContext.HTTP_RESPONSE);
		HttpClient httpClient = new HttpClient();
		GetMethod getMethod = new GetMethod(url);
		try {
			//关闭连接
			getMethod.setRequestHeader("Connection","close");
			getMethod.setRequestHeader("Content-Type","application/x-www-form-urlencoded;charset=utf-8");
			int statusCode = httpClient.executeMethod(getMethod);
			if (statusCode != HttpStatus.SC_OK) {
				System.out.println("Method failed:"
						+ getMethod.getStatusLine());
			} else {
				String json = getMethod.getResponseBodyAsString();
				renderText(response, FormatJson.showJson(json));
			}
			getMethod.releaseConnection();
		} catch (Exception e) {
			log.error("ProControlAction Exception,url = " + url, e);
		}
	}
