java - Spring 3 为 ThreadPoolTask​​Executor 设置 ThreadFactory

Question

这是可能的还是由应用服务器管理？将 ThreadPoolTask​​Executor ref 传递给 bean 很简单，但尝试在上述执行程序上设置 threadfactory 似乎没有任何效果......

Answer 1

实际上，设置一个 ThreadFactory 也是很简单的:

<bean id="taskExecutor" class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor">
    <property name="threadFactory" ref="threadFactory"/>
</bean>
<bean id="threadFactory" class="org.springframework.scheduling.concurrent.CustomizableThreadFactory">
    <constructor-arg value="Custom-prefix-"/>
</bean>

或:

@Bean
public ThreadPoolTaskExecutor taskExecutor() {
    final ThreadPoolTaskExecutor taskExecutor = new ThreadPoolTaskExecutor();
    taskExecutor.setThreadFactory(threadFactory());
    return taskExecutor;
}

@Bean
public ThreadFactory threadFactory() {
    return new CustomizableThreadFactory("Custom-prefix-");
}

请注意 ThreadPoolTaskExecutor从 ExecutorConfigurationSupport 延伸这就是setThreadFactory(java.util.concurrent.ThreadFactory)已定义。
