在Jetty 9中更改线程池大小

Question

如何在嵌入式Jetty 9中更改线程池大小？我们需要任何特定的组件吗？

Answer 1

来自docs:

Server实例提供ThreadPool实例,该实例是其他Jetty服务器组件使用的默认Executor服务.线程池的主要配置是最大和最小大小,并在etc/jetty.xml中设置.

<Configure id="server" class="org.eclipse.jetty.server.Server">   
<Set name="threadPool">
    <New class="org.eclipse.jetty.util.thread.QueuedThreadPool">
      <Set name="minThreads">10</Set>
      <Set name="maxThreads">1000</Set>
    </New>
</Set> 
</Configure>

要么

QueuedThreadPool threadPool = new QueuedThreadPool(100, 10);
Server server = new Server(threadPool);

Answer 2

如上所述,并在上面的Java代码示例中进行了更正,现在将线程池作为Jetty 9(及更高版本)中的构造函数参数提供.

更正后的XML示例:

<Configure id="Server" class="org.eclipse.jetty.server.Server">

    <!-- =========================================================== -->
    <!-- Configure the Server Thread Pool.                           -->
    <!--                                                             -->
    <!-- Consult the javadoc of o.e.j.util.thread.QueuedThreadPool   -->
    <!-- for all configuration that may be set here.                 -->
    <!-- =========================================================== -->
    <Get name="ThreadPool">
        <Set name="minThreads" type="int">10</Set>
        <Set name="maxThreads" type="int">200</Set>
        <Set name="idleTimeout" type="int">60000</Set>
        <Set name="detailedDump">false</Set>
    </Get>
    ...
