在调用 Soap WebService 期间，我们遇到了这个错误。背后的原因可能是什么？

我正在使用 JDK 7 更新 U67（64 位）、Spring 3.1.1.RELEASE、Spring WS 2.1.0.RELEASE（spring-ws-core-2.1.0.RELEASE.jar），

这是堆栈跟踪日志：

有没有人遇到过同样的问题？

该错误意味着运行 SOAP 调用的线程已被中断，而堆栈跟踪 ( com.sun.xml.internal.messaging.saaj.util.ParserPool#get()) 中显示的特定方法恰好在该中断发生后执行了对可中断方法的第一次调用。由于线程属于线程池，这可能是调用shutdownNow()了ThreadPoolExecutor.

我有这个错误，它是由于我在ConfigurableApplicationContext从 run 方法返回时调用 close 引起的

@SpringBootApplication
public class MyApplication {
    public static void main(String[] args) {
        SpringApplication.run(MyApplication.class, args).close();
    }
}

删除.close()使中断消失。

实际上，shutdownNow() 是这个问题背后的根本原因。作为一种解决方案，shutdownNow() 被 shutdown() 取代，原因如下：

  • shutdownNow() 告诉执行器服务（ScheduledExecutorService）它不能接受新任务，并尝试通过中断抛出 java.lang.InterruptedException 的相关线程来取消已经提交的任务，而方法 shutdown() 只会告诉执行器服务，它不能接受新的任务，但已经提交的任务继续运行到最后。
