本文主要介紹CXF WebService 客戶端如何設定超時時間，以及相關引數的介紹。

在使用WebService時，出現了超時的異常，如下。

最初的想法是覺得肯定有地方是可以設定這麼一個超時時間的，但是卻苦苦找不到設定的地方，最終經過各種折騰，Google之百度之，找到了解決辦法。

Using WebService, we usually set in the client request timeout limit in order to avoid long time to connect to the server is unavailable. CXF environment, the client can be configured through two properties timeout limit:

在使用網路服務時，通常需要為客戶端設定請求超時時間，以避免長時間的去連線不可用的伺服器。在CXF環境中，客戶端可以通過兩個引數配置超時限制：

• The ConnectionTimeout: WebService based TCP connection, this property can be understood as TCP handshake time settings, exceeds the time that it is the connection timeout in milliseconds, the default is 30000 milliseconds, or 30 seconds.

• ConnectionTimeout: WebService是基於TCP連線的，因此這個屬性可以理解為設定TCP握手時間，若超出這個時間就認為連線超時。預設的時間單位是毫秒，預設設定是30000毫秒，即30秒。

• ReceiveTimeout: this property WebService request is sent to wait for a response time exceeds the length of time that it is the response timeout in milliseconds, the default is 60000 milliseconds, or 60 seconds.

• ReceiveTimeout: 這個屬性表示傳送WebService請求後所等待響應的時間，若超過設定的時間則認為超時。預設的時間單位是毫秒，預設設定是60000毫秒，即60秒。

Here are two ways to configure the client:
下面有兩種方法可以在客戶端進行配置：

In the spring configuration file settings.
- 在spring配置檔案中進行配置。

<?xml version="1.0" encoding="UTF-8"?>      
<beans xmlns="http://www.springframework.org/schema/beans"      
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"      
    xmlns:jee="http://www.springframework.org/schema/jee"      
    xmlns:jaxws="http://cxf.apache.org/jaxws"      
    xmlns:http-conf="http://cxf.apache.org/transports/http/configuration"       
    xsi:schemaLocation="http://www.springframework.org/schema/beans     
         http://www.springframework.org/schema/beans/spring-beans-2.0.xsd      
         http://www.springframework.org/schema/jee     
         http://www.springframework.org/schema/jee/spring-jee-2.0.xsd      
         http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd      
         http://cxf.apache.org/transports/http/configuration     
         http://cxf.apache.org/schemas/configuration/http-conf.xsd ">      
   <http-conf:conduit name="{WSDL Namespace}portName.http-conduit">       
      <http-conf:client ConnectionTimeout="10000" ReceiveTimeout="20000"/>      
   </http-conf:conduit>       
</beans>    

It should be noted there are several places:
1, we need to specify the http-conf namespace: xmlns: http-conf =
2, the location of the specified pattern:
Http-conf: Conduit name attribute to specify service settings to take effect. by the service namespace in the WSDL port name. “http-conduit”, the name attribute, such as the {} HelloWorld.http in-conduit. If the name attribute is set to “http-conduit”, will be effective for all services.

如下幾點需要注意：
1. 需要指定http-conf的名稱空間：xmlns:http-conf="http://cxf.apache.org/transports/http/configuration"
2. 指定模式位置: http://cxf.apache.org/transports/http/configuration http://cxf.apache.org/schemas/configuration/http-conf.xsd
3. http-conf:conduit中的name屬性,指定設定生效的服務。name屬性由service的namespace、WSDL中的 port name和”.http-conduit”組成，如{http://apache.org/hello_world}HelloWorld.http- conduit。如果將name屬性設定為“*.http-conduit”，則會對所有服務生效。

Java code to be set.
- 使用Java程式碼設定：

Client client = ClientProxy.getClient (port);
HTTPConduit http = (HTTPConduit) client.getConduit();
To = new HTTPClientPolicy (HTTPClientPolicy httpClientPolicy);
httpClientPolicy.setConnectionTimeout (36000);
httpClientPolicy.setAllowChunking (false);
httpClientPolicy.setReceiveTimeout (32000);
http.setClient (httpClientPolicy);

Server-side set spring code is as follows:
- 伺服器端的spring程式碼配置如下：

<! - On the server side to set the response timeout limit, now is the default value of 30 seconds ->
<http-conf:destination name="*.http-conduit">
<http-conf:server ReceiveTimeout="30000" />
</ Http-conf: destination>
