java - 如何使用spring @Async创建独立线程

Question

我正在将 spring @Async 与 weblogic workmanager 一起使用，Spring版本为3.2.2

网络.xml :

<resource-ref>
    <res-ref-name>ReportWorkmanager</res-ref-name>
    <res-type>commonj.work.WorkManager</res-type>
    <res-auth>Container</res-auth>
    <res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>

网络逻辑.xml :

<work-manager>
    <name>ReportWorkmanager</name>
    <fair-share-request-class>
        <name>Priority</name>
        <fair-share>100</fair-share>
    </fair-share-request-class>

    <min-threads-constraint>
        <name>MinThreadCount</name>
        <count>15</count>
    </min-threads-constraint>

    <max-threads-constraint>
        <name>MaxThreadCount</name>
        <count>25</count>
    </max-threads-constraint>

    <work-manager-shutdown-trigger>
        <max-stuck-thread-time>120</max-stuck-thread-time>
        <stuck-thread-count>25</stuck-thread-count>
    </work-manager-shutdown-trigger>
</work-manager>

Spring 配置文件:

 <bean id="reportWorkManagerTaskExecutor"
    class="org.springframework.scheduling.commonj.WorkManagerTaskExecutor">
    <property name="workManagerName" value="java:comp/env/ReportWorkmanager" />
</bean>

Controller :

@RequestMapping(value = "/publish", method = RequestMethod.POST)
public MarketingScenario publishReport(@RequestBody final PublishReportDTO reportDTO, final HttpServletRequest request) throws Exception {


    reportDTO.setReqUserName(DominoWebUtil.getLoggedInUserName(request));
    reportEngine.publishReport(reportDTO);
    MarketingScenario scenario =  scenarioService.findMarketingScenarioById(reportDTO.getScenarioId());
    _LOGGER.debug("Job submitted , successfully came out for scenario id {}", reportDTO.getScenarioId());
    return scenario;
}

服务:

@Async(value = "reportWorkManagerTaskExecutor")
public void publishReport(final PublishReportDTO reportDTO) {

    //Some long run job
}

每当请求来自 fornt end 时， Controller 应该通过调用服务方法来启 Action 业，并且它应该返回响应而不等待服务作业。

当未应用@Async 时，一切都很顺利，但当我应用时，由于我的请求线程已完成，服务线程被终止。

请告诉我，使用@Async 如何创建独立于请求线程的线程。

独立线程可能会运行 2 分钟或 20 分钟，具体取决于输入。

Answer 1

首先，Spring's docs声明使用非默认执行程序的 @Async 应该用 @Async("otherExecutor") 注释而不是 @Async(value="otherExecutor").

另外，我想我不太明白你的意思:

When @Async is not applied everything goes perfectly but when I applied, service thread is getting killed because of my request thread is done.

我假设你的意思是它运行正常但在同一个线程上。在这种情况下，它非常有意义，因为您正在同步运行该方法。
