Httpclient超时timeout设置

 

一：链接超时：connectionTimeout

 

     1：指的是链接一个url的链接等待时间。

二：读取数据超时：soTimeout

     1：指的是链接上一个url，获取response的返回等待时间。

For example:

 // 设置链接时间
            client.getHttpConnectionManager().getParams().setConnectionTimeout(5000);
            client.getHttpConnectionManager().getParams().setSoTimeout(60000);

 /**
     * 消息发送处理.
     * HTTP发送方式
     * @param content 消息内容
     * @return 返回消息
     */
	private GeneralReturnInfo postHttpData(String content) {
        GeneralReturnInfo out = new GeneralReturnInfo();
        String result = "";
        PostMethod postMethod = new PostMethod(serviceUrl);
        
        try {
            postMethod.setParameter("content", content);

            HttpClient client = new HttpClient();
            client.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET, "UTF-8");
            // 设置链接时间
            client.getHttpConnectionManager().getParams().setConnectionTimeout(5000);
            client.getHttpConnectionManager().getParams().setSoTimeout(60000);
            int status = client.executeMethod(postMethod);
            if (status == HttpStatus.SC_OK) {
                result = postMethod.getResponseBodyAsString();
                if (StringUtils.isEmpty(result)) {
                	String msg="HTTP访问失败(返回报文为空)(" + serviceUrl + ").";
					System.err.println(msg);
                    throw new AdapterException(ErrorType.CLIENT_NET_ERROR, "", msg);
                }
                
                out = JSON.parseObject(result, GeneralReturnInfo.class);
            } else {
            	String msg="HTTP访问:返回状态不等于200(" + status + ")(" + serviceUrl + ")).";
                System.err.println(msg);
                throw new AdapterException(ErrorType.CLIENT_NET_ERROR, "", msg);
            }

        } catch (Exception e) {
        	
        	
            // 将新产生的例外封装
            if (e instanceof AdapterException) {
                throw (AdapterException) e;
            } else if (e instanceof ConnectException) {
                System.err.println("HTTP访问失败(链接失败)(" + serviceUrl + ")).");
                throw new AdapterException(ErrorType.CLIENT_NET_ERROR, e, "HTTP访问失败(链接失败)(" + serviceUrl + ")).");
            } else if (e instanceof ConnectTimeoutException) {
                System.err.println("HTTP访问失败(链接超时)(" + serviceUrl + ")).");
                throw new AdapterException(ErrorType.CLIENT_NET_ERROR, e, "HTTP访问失败(链接超时)(" + serviceUrl + ")).");
            } else if (e instanceof SocketTimeoutException) {

            } else {
                System.err.println("HTTP访问失败(调用异常)(" + serviceUrl + ")).");
                throw new AdapterException(ErrorType.CLIENT_NET_ERROR, e, "HTTP访问失败(调用异常)(" + serviceUrl + ")).");
            }
        } finally {
            // 释放链接
            postMethod.releaseConnection();
        }
