如何在Java中記錄純文本？ SimpleFormatter還編寫XML

Question

我正在使用SimpleFormatter編寫日誌文件。這些是用XML而不是純文本編寫的。我將它寫成純文本的答案都只是說使用簡單的格式化程序（例如https://stackoverflow.com/a/10469185/651779）。這是我的自定義記錄格式，從SimpleFormatter延伸：

class CustomRecordFormatter extends SimpleFormatter { 
    @Override 
    public String format(final LogRecord r) { 
     StringBuilder sb = new StringBuilder(); 
     sb.append(formatMessage(r)).append(System.getProperty("line.separator")); 
     if (null != r.getThrown()) { 
      sb.append("Throwable occurred: "); //$NON-NLS-1$ 
      Throwable t = r.getThrown(); 
      PrintWriter pw = null; 
      try { 
       StringWriter sw = new StringWriter(); 
       pw = new PrintWriter(sw); 
       t.printStackTrace(pw); 
       sb.append(sw.toString()); 
      } finally { 
       if (pw != null) { 
        try { 
         pw.close(); 
        } catch (Exception e) { 
         // ignore 
        } 
       } 
      } 
     } 
     return sb.toString(); 
    } 
} 

，這是我如何設置記錄

public class DeconvolutionLogger { 
    static private FileHandler outfilePath; 
    protected final static Logger log = Logger.getLogger(Logger.GLOBAL_LOGGER_NAME); 
    static public void setup(String outputDir) throws IOException { 
    // get the global logger to configure it 
    log.setLevel(Level.INFO); 
    DateFormat dateFormat = new SimpleDateFormat("yyyyMMdd"); 
    Date date = new Date(); 
    setOutfilePath(new FileHandler(outputDir+"/DeconvolutionLog_"+dateFormat.format(date)+".txt")); 
    CustomRecordFormatter customFormatter = new CustomRecordFormatter(); 
    ConsoleHandler consoleHandler = new ConsoleHandler(); 
    consoleHandler.setFormatter(customFormatter); 
    log.setUseParentHandlers(false); 
    log.addHandler(consoleHandler); 
    log.addHandler(outfilePath); 

    } 
} 

我缺少什麼，它不寫純文本？

Answer 1

outfilePath的格式化程序是stil XMLFormatter。
您應該致電outfilePath.setFormatter(customFormatter);更改它。
