CXF发送、接收消息超时设置
在使用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/configurationhttp://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);
