JSR352 - JBERET - 如何檢查Java批處理程序作業日誌？

Question

我正在嘗試使用JBERET實現在Java SE模式下運行JSR352 Java批處理程序。我可以看到我的main（）方法得到執行。在這個main（）方法中，我得到了一個工作操作員的處理並開始工作。

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，我的閱讀器，處理器，寫入器或偵聽器中沒有看到任何日誌語句被打印。

我有一個logging.properties定義並從我的項目src/main/resources/META-INF文件夾加載。我的main（）方法中的日誌語句根據它進行打印，但是，我的讀寫器/處理器和偵聽器中的日誌語句根本不打印。

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(); 
     } 
    } 
} 

爲什麼我的日誌報表（java的日誌庫）在我的Java批處理程序進行打印？

以下是main（）方法的日誌。我可以清楚地看到工作已經開始，但不知道爲什麼批處理程序的日誌語句沒有打印出來。

這是一個Listener代碼，它有一個Sysout和Log語句。他們都沒有得到我的Eclipse控制檯打印。

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"); 
    } 

}

要查詢作業的執行狀態，你可以直接調用相應的API上JobOperator，例如，public JobExecution getJobExecution(long executionId)。返回的JobExecution對象包含最新的數據。

對於作業存儲庫，如果jdbc作業存儲庫對您的應用程序來說過重，則可以選擇內存作業存儲庫。但是對於默認的H2數據庫，您可以配置爲具有基於嵌入式或基於文件的H2數據庫，而不是客戶端 - 服務器模式，以限制資源消耗。

對於日誌記錄問題，您可以創建一個JIRA issue或github issue，並附上一個可重複的測試應用程序？
