在用cxf??開發webservice應用時，客戶端老報?

java.net.SocketTimeoutException: Read timed out?

原因為連接超時,google 參考鏈接?

Spring下設置CXF的WebService客戶端超時時長?
http://ajava.org/course/open/16514.html?
https://cwiki.apache.org/CXF20DOC/client-http-transport-including-ssl-support.html?? (官方)?

在Spring+CXF的WebService環境下,客戶端有兩個時間屬性是可配置的,分別是ConnectionTimeout和ReceiveTimeout.???
ConnectionTimeout--WebService以TCP連接為基礎,這個屬性可以理解為tcp的握手時的時間設置,超過設置的時間長則認為是連接超時.以毫秒為單位,默認是30000毫秒,即30秒.??
??
ReceiveTimeout -- 這個屬性是發送WebService的請求后等待響應的時間,超過設置的時長就認為是響應超時.以毫秒為單位,默認是60000毫秒,即60秒.?

?? 一、在spring的配置文件中進行設置(客戶端)。?

Xml代碼??
<?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="{http://impl.service.product.super.com/}ProjectService.http-conduit">???
??????? <http-conf:client ConnectionTimeout="10000" ReceiveTimeout="20000"/>??
??? </http-conf:conduit>???
</beans>???
這里需要注意的有幾個地方:???
需要指定http-conf名稱空間?xmlns:http-conf =http://cxf.apache.org/transports/http/configuration???
指定模式位置:? http://cxf.apache.org/transports/http/configuration http://cxf.apache.org/schemas/configuration/http-conf.xsd????
http-conf:conduit中的name屬性,指定設置生效的服務,如例子中,只對服務名為{http://impl.service.product.sww.com/}ProjectService的服務生效.???
使用下面的設置則會對所有服務生效???
< http-conf:conduit?? name = "*.http-conduit" >??????????
</ http-conf:conduit >???

二、通過java代碼進行設置。?

Java代碼??
Client client = ClientProxy.getClient(port);??????
HTTPConduit http = (HTTPConduit) client.getConduit();??????
HTTPClientPolicy httpClientPolicy = new HTTPClientPolicy();??????
httpClientPolicy.setConnectionTimeout(36000);??????
httpClientPolicy.setAllowChunking(false);??????
httpClientPolicy.setReceiveTimeout(32000);??????
http.setClient(httpClientPolicy);????
另外，WSDL中的endpoint的地址不一定是有效的，為避免客戶端請求使用該地址，我們在請求前應通過以下方式強行設置為可用的服務地址。?
? ((BindingProvider) port).getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY,serviceUrl);?
