CXF客户端配置请求超时限制

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

 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 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。

    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);
