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);

1 楼 tangduDream 2012-01-18 我想问你一个问题,为什么我配置:
//超时设置
Client clientP = ClientProxy.getClient(companyService);
HTTPConduit http = (HTTPConduit) clientP.getConduit();
HTTPClientPolicy httpClientPolicy = new HTTPClientPolicy();
//httpClientPolicy.setConnectionTimeout(20000);
httpClientPolicy.setReceiveTimeout(5*60*1000);
//httpClientPolicy.setAllowChunking(false);
http.setClient(httpClientPolicy);
我设置了5分钟 ,可是服务端却在5分钟内还在运行,直到超时?

这是为什么呢?
