小编Fry*_*der的帖子

creditcard-monk:
 build:
  context: ./creditcard
  dockerfile: Dockerfile
  args:
    JAR_FILE: target/creditcard-1.0.0.jar

Docker compose 版本 3.0。jar_file 参数用于将 jar 文件复制到 docker 容器下的 spring-boot jar

我收到错误failed to build: COPY failed: stat /var/lib/docker/tmp/docker-builder347176151/target/creditcard-1.0.0.jar: no such file or directory

我认为提及上下文，将从目标文件夹中读取 jar 。但 docker-compose 似乎没有从指定的上下文中读取文件

请帮忙。注意：- docker 文件很简单，由 alpine-java-8 构建，并使用复制命令将 jar 复制到容器以启动 Spring Boot 应用程序

*我遵循https://www.anchormen.nl/spark-docker/，执行命令时，apache启动失败，提示“-”无法识别。我很新，希望从我们值得信赖的社区成员那里寻求帮助。

bash /opt/spark/sbin/start-master.sh

*与本文唯一的不同是我使用了仅限于linux的alpine linux。

验证我试图隐藏日志文件..并得到相同的错误。docker中的alpine linux无法识别“-”。我做错了吗？

[已解决]谢谢罗伯特。

如果有人寻找答案，请在您的docker-file中添加以下内容

RUN apk update && apk upgrade && apk add curl ca-certificates tar supervisor bash procps coreutils

无法将类型'java.lang.String'的属性值转换为属性'cacheManager'的必需类型'net.sf.ehcache.CacheManager'

<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager" p:cache-manager="ehcache"/>
<!-- Ehcache library setup -->
<bean id="ehcache" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean" p:config-location="classpath:com/spring/test/ehcache/config/ehcache.xml"/>

在websphere中运行spring的workmanager任务执行程序时收到异常.以下是我的代码

<bean id="workManager" class="org.springframework.scheduling.commonj.WorkManagerTaskExecutor">
    <property name="workManagerName" value="wm/MyWorkManager"/>
    <property name="resourceRef" value="false"/>
</bean>

<bean name="myWorkManager" class="com.spring.test.services.concurrent.ConcurrentWorkManager" />
<bean name="myWorkListener" class="com.spring.test.services.concurrent.ConcurrentWorkListener" />

我的ConcurrentWorkManager中的代码

@Autowired
private WorkManagerTaskExecutor workManager;

@Autowired
private WorkListener myWorkListener;

    if(workList==null){
     throw new WorkException("There are no works present in worklist to do work");
    }

    ArrayList<WorkItem> workItems = new ArrayList<WorkItem>();
    for(Work work : workList){
        workItems.add(workManager.schedule(work,myWorkListener));
    }
    workManager.waitForAll(workItems,WorkManager.INDEFINITE);


    for(WorkItem work:workItems){
        ConcurrentWorker worker=(ConcurrentWorker)work.getResult();
        resultString.add(worker.getResult());
    }

现在当我执行我的代码时,它在workmanager.schedule(work)方法中给出了stackoverflow异常

stackoverflow异常
