Question

当我尝试从我已部署的CXF Web服务从WS客户端调用方法时，我的连接超时。两者都使用自定义拦截器，并且由于多次调用而导致服务过载。

我尝试了多种解决方案来禁用超时或增加超时但都失败了。

首先，我尝试创建如下的CXF配置文件：

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:http-conf="http://cxf.apache.org/transports/http/configuration"
    xsi:schemaLocation="http://cxf.apache.org/transports/http/configuration
           http://cxf.apache.org/schemas/configuration/http-conf.xsd
           http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans.xsd">

    <http-conf:conduit name="*.http-conduit">
        <http-conf:client CacheControl="no-cache"
            ConnectionTimeout="0" ReceiveTimeout="0" AllowChunking="false" />
    </http-conf:conduit>
</beans>

然后，我强制我的应用程序使用Java系统属性-Dcxf.config.file=/home/test/resources/cxf.xml

加载它

在日志中，我可以看到配置已被读取，因此可能已应用

INFO：已加载的配置文件/home/test/resources/cxf.xml。

不幸的是，连接超时仍然存在。

我尝试的第二个解决方案包括使用以下代码以编程方式在所有客户端上设置策略：

public static void setHTTPPolicy(Client client) {
    HTTPConduit http = (HTTPConduit) client.getConduit();

    HTTPClientPolicy httpClientPolicy = new HTTPClientPolicy();
    httpClientPolicy.setConnectionTimeout(0);
    httpClientPolicy.setReceiveTimeout(0);
    httpClientPolicy.setAsyncExecuteTimeout(0);

    http.setClient(httpClientPolicy);
}

但是再次出现连接超时。

我错过了什么吗？是否还有其他超时配置？欢迎任何帮助。

CXF允许您为Web服务端点配置线程池。这样，您就可以满足由于稀缺的请求处理资源而导致的超时。以下是使用cxf中的<jaxws:endpoint/>选项的示例配置：

<jaxws:endpoint id="serviceBean"  implementor="#referenceToServiceBeanDefinition" address="/MyEndpointAddress">
        <jaxws:executor>
             <bean id="threadPool" class="java.util.concurrent.ThreadPoolExecutor">  
                 <!-- Minimum number of waiting threads in the pool -->
                 <constructor-arg index="0" value="2"/>
                 <!-- Maximum number of working threads in the pool -->
                 <constructor-arg index="1" value="5"/>
                 <!-- Maximum wait time for a thread to complete execution -->
                 <constructor-arg index="2" value="400000"/>
                 <!-- Unit of wait time -->
                 <constructor-arg index="3" value="#{T(java.util.concurrent.TimeUnit).MILLISECONDS}"/>
                 <!-- Storage data structure for waiting thread tasks -->
                 <constructor-arg index="4" ref="taskQueue"/>
             </bean>
         </jaxws:executor>
    </jaxws:endpoint>

    <!-- Basic data structure to temporarily hold waiting tasks-->
    <bean id="taskQueue" class="java.util.concurrent.LinkedBlockingQueue"/>
