当我尝试从 WS 客户端调用我已部署的 CXF Web 服务中的方法时,连接超时。两者都使用自定义拦截器,并且服务由于多次调用而过载。

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,我尝试创建一个 CXF 配置文件,如下所示:

<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 系统属性加载它-Dcxf.config.file=/home/test/resources/cxf.xml

在日志中,我可以看到配置已读取,因此可能已应用

信息:已加载配置文件 /home/test/resources/cxf.xml。

不幸的是,连接超时仍然发生。

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);
}

但再次发生连接超时。

我错过了什么吗?是否有其他一些超时配置?欢迎任何帮助。

CXF 允许您为 Web 服务端点配置线程池。这样,您可以应对由于请求处理资源稀缺而发生的超时。<jaxws:endpoint/>以下是使用cxf中的选项的示例配置:

<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"/>
