主要在客户端调用时设置 :
- 在使用WebService的时候,我们可能需要一个备份的WebService服务器.一旦主服务器down了,我们可以使用备份的服务器.那么这里就需要对客服端连接服务器的时间做一个修改.
- 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.
- beans.xml 设置的例子:
- <?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:
- 1:需要指定http-conf名称空间 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:client……>
- </http-conf:conduit>
- 更详细的配置请参考CXF官方文档:
- http://cwiki.apache.org/CXF20DOC/client-http-transport-including-ssl-support.html
`2.代码编写:
private static void recieveTimeOutWrapper(Object o)
{
Conduit conduit = (ClientProxy.getClient(o).getConduit());
HTTPConduit hc = (HTTPConduit)conduit;
HTTPClientPolicy client = new HTTPClientPolicy();
client.setReceiveTimeout(1000 * 60 * 5); // 5分钟超时时间。 该时间为响应超时。
// client.setConnectionTimeout(1000 * 45); // 45秒的连接超时。
hc.setClient(client);
}
recieveTimeOutWrapper(o) 包装每一个服务
使用WebService时,我们通常都会在客户端中设置请求超时的限制,以避免长时间的去连接不可用的服务器。在CXF的环境下,客户端可通过两个属性配置超时限制:
- ConnectionTimeout - WebService以TCP连接为基础,这个属性可以理解为TCP握手时的时间设置,超过设置的时间就认为是连接超时.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.
- 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);
spring+cxf配置方式:
- <?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>
这里需要注意的有几个地方:
1、需要指定http-conf名称空间: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属性,指定设置生效的服务。name属性由service的namespace、WSDL中的 port name和".http-conduit"组成,如{http://apache.org/hello_world}HelloWorld.http- conduit。如果将name属性设置为“*.http-conduit”,则会对所有服务生效。
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);

//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?
我也不知道,我设置了之后感觉也没啥反映,所以我都改用httpclient做了,报文封装自己做
//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);
