为什么在收到 SIGTERM 信号时不能正常关闭 SOAP 服务异步调用

  • 772

我在收到 SIGTERM 命令后实现了 SpringBoot 应用程序的正确终止。设置 SpringBoot 的设置：

server:
  shutdown: graceful

spring.task.execution:
  pool:
    allow-core-thread-timeout: true
    keep-alive: 3m
  shutdown:
    await-termination: true
    await-termination-period: 3m

我还尝试使用 ThreadPoolTask​​Executor：

ThreadPoolTaskExecutor defaultExecutor = new ThreadPoolTaskExecutor();
    defaultExecutor.setKeepAliveSeconds(180);
    defaultExecutor.setWaitForTasksToCompleteOnShutdown(true);
    defaultExecutor.setAwaitTerminationSeconds(180);

但遇到了问题。在异步线程中调用 SOAP 方法，该方法崩溃并出现错误：

ERROR [iso20022.app.FCR,3b58933b54e5e47c,1eb7da1d0650e9d9] 2808 --- [     h2h-async1] r.a.h.c.RepeaterInvocationHandler        : error on calling jdk.proxy6.$Proxy236.wsAccountBaseInfoGet

在此方法之前，feign 客户端通过 REST 搜索并保存到数据库，没有任何问题。该错误只能用 catch(Error e) 捕获，因为 Exception 不会被捕获。如果有人遇到类似的，提示去哪里挖？

    问题出在图书馆。曾是：

    implementation group: 'org.glassfish.main.javaee-api', name: 'javax.jws', version: '3.1.2.2'
implementation group: 'javax.xml.ws', name: 'jaxws-api', version: '2.3.1'
implementation group: 'com.sun.xml.ws', name: 'jaxws-rt', version: '2.3.1'

    需要做：

    implementation 'jakarta.xml.bind:jakarta.xml.bind-api:4.0.0'
implementation 'jakarta.xml.ws:jakarta.xml.ws-api:4.0.0'
implementation 'jakarta.activation:jakarta.activation-api:2.1.2'
implementation 'com.sun.xml.ws:jaxws-rt:4.0.1'
implementation 'com.sun.xml.bind:jaxb-impl:2.3.1'
implementation 'org.glassfish.jaxb:jaxb-runtime:4.0.2'
runtimeOnly 'jakarta.xml.soap:jakarta.xml.soap-api:3.0.0'
runtimeOnly 'com.sun.xml.messaging.saaj:saaj-impl:3.0.2'

    因此，修复从 javax 到 jakarta 的类中的导入
