CXF客户端配置请求超时限制-SocketTimeoutException

在用cxf  开发webservice应用时，客户端老报

java.net.SocketTimeoutException: Read timed out

原因为连接超时,google 参考链接

Spring下设置CXF的WebService客户端超时时长
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环境下,客户端有两个时间属性是可配置的,分别是ConnectionTimeout和ReceiveTimeout.  
ConnectionTimeout--WebService以TCP连接为基础,这个属性可以理解为tcp的握手时的时间设置,超过设置的时间长则认为是连接超时.以毫秒为单位,默认是30000毫秒,即30秒. 
 
ReceiveTimeout -- 这个属性是发送WebService的请求后等待响应的时间,超过设置的时长就认为是响应超时.以毫秒为单位,默认是60000毫秒,即60秒.

   一、在spring的配置文件中进行设置(客户端)。

Xml代码 
<?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>   

<?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>  
这里需要注意的有几个地方:  
需要指定http-conf名称空间 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属性,指定设置生效的服务,如例子中,只对服务名为{http://impl.service.product.sww.com/}ProjectService的服务生效.  
使用下面的设置则会对所有服务生效  
< http-conf:conduit   name = "*.http-conduit" >         
</ http-conf:conduit >  

二、通过java代码进行设置。

Java代码 
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);   

    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，为避免客户端请求使用该地址，我们在请求前应通过以下方式强行设置为可用的服务地址。
  ((BindingProvider) port).getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY,serviceUrl);
