我收到以下警告,然后是 NPE,其服务使用 CXF (2.5.2) 创建,在 Jetty 上运行。有人知道如何按照警告中的建议增加执行程序队列的大小吗?

org.apache.cxf.interceptor.OneWayProcessorInterceptor handleMessage
WARNING: Executor queue is full, run the oneway invocation task in
caller thread. Users can specify a larger executor queue to avoid
this.

更新:感谢接受的答案,我创建了一个包含以下 spring bean 的 xml 文件:

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">

    <bean id="cxf.default.workqueue" class="org.apache.cxf.workqueue.AutomaticWorkQueueImpl">
        <property name="name" value="default" />
        <property name="queueSize" value="512" />
    </bean>
</beans>

它不容易配置(您需要将自己的实例注册AutomaticWorkQueue到应用程序的总线中)。处理@OneWay调用的最大线程数的默认值为 256,这意味着服务器最多可以同时处理 256 个@OneWay请求而不会阻塞调用者线程。

在您的情况下,您可以根据规范http://grepcode.com/file/repo1.maven.org/maven2org.apache.cxf.workqueue.AutomaticWorkQueueImpl创建具有属性name="default"并设置队列大小和初始线程数、上限和下限的类型的 spring bean /org.apache.cxf/cxf-rt-core/2.1.4/org/apache/cxf/workqueue/AutomaticWorkQueueImpl.java
