Question

我正在尝试使用JBERET实现在Java SE模式下运行JSR352 java批处理程序。我可以看到我的main（）方法被执行了。在这个main（）方法中，我得到了一个作业操作员并开始工作。

public static void main(String[] args) {

    LoggingConfig logConfiguration = new LoggingConfig();

    logger.info("Begining Batch with JBeret approach");

    JobOperator jo = BatchRuntime.getJobOperator();
    long id = jo.start("PilotJob", null);

    logger.info("End of Batch");

}

但是，我没有在我的读者，处理器，作家或听众中看到任何日志声明被打印出来。

我从我的项目src / main / resources / META-INF文件夹中定义并加载了logging.properties。我的main（）方法中的日志语句是根据它打印的，但我的读/写器/处理器和监听器中的日志语句根本不打印。

public class LoggingConfig {
    public LoggingConfig() {
        try {
            // Load a properties file from class path that way can't be achieved
            // with java.util.logging.config.file

              final LogManager logManager = LogManager.getLogManager(); 
              try (final InputStream is = getClass().getResourceAsStream("/META-INF/logging.properties")) 
              {
                  logManager.readConfiguration(is);
              }

        } catch (Exception e) {
            System.out.println("Error while reading Log configuration file");
            e.printStackTrace();
        }
    }
}

为什么我的java批处理程序中的日志语句（java日志库）不能打印？

以下是main（）方法的日志。我可以清楚地看到作业已经开始，但不确定为什么批处理程序的日志语句没有被打印出来。

这是一个包含Sysout和Log语句的Listener代码。它们都没有在我的Eclipse控制台中打印出来。

import java.util.logging.Logger;

import javax.batch.api.listener.AbstractJobListener;

public class PilotLibJobListener extends AbstractJobListener {

    private final static Logger logger = Logger.getLogger("PilotLibJobListener");   

    public void beforeJob() {
        BatchListenerRecorder.batchListenersCountDownLatch.countDown();
        System.out.println("Before Job");
        logger.info("MyJobListener.beforeJob");
    }

    @Override
    public void afterJob() {
        BatchListenerRecorder.batchListenersCountDownLatch.countDown();
        logger.info("MyJobListener.afterJob");
    }

}

要查询作业执行状态，您只需在JobOperator上调用相应的API，例如public JobExecution getJobExecution(long executionId)。返回的JobExecution对象包含最新数据。

对于作业存储库，如果jdbc作业存储库对于您的应用来说太重了，您可以选择内存中的作业存储库。但是使用默认的H2数据库，您可以配置为具有嵌入式或基于文件的H2数据库，而不是客户端 - 服务器模式，以限制资源消耗。

对于日志记录问题，您可以创建JIRA issue或github issue，并附加可重现的测试应用吗？
