我收到了以下警告,然后是一个NPE,其中包含使用在Jetty上运行的CXF(2.5.2)创建的服务。有人知道如何按照警告中的建议增加执行程序队列大小吗?
org.apache.cxf.interceptor.OneWayProcessorInterceptor handleMessage

更新:由于接受了回答,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>
答案 0 :(得分:2)
它不易配置(您需要将自己的AutomaticWorkQueue
实例注册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提供256个@OneWay
个请求,而不会阻塞调用者线程。
在您的情况下,您可以创建一个org.apache.cxf.workqueue.AutomaticWorkQueueImpl
类型的spring bean,其属性为name="default"
&amp;设置队列大小&amp;初始线程数,高和&amp;根据规范http://grepcode.com/file/repo1.maven.org/maven2/org.apache.cxf/cxf-rt-core/2.1.4/org/apache/cxf/workqueue/AutomaticWorkQueueImpl.java
