本文整理了Java中org.apache.log4j.Layout类的一些代码示例，展示了Layout类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Layout类的具体详情如下：
包路径：org.apache.log4j.Layout
类名称：Layout

Layout介绍

[英]Extend this abstract class to create your own log layout format.
[中]扩展此抽象类以创建自己的日志布局格式。

代码示例

private List<Event> parseEvents(LoggingEvent loggingEvent) {
 Map<String, String> headers = new HashMap<>();
 headers.put(Log4jAvroHeaders.LOGGER_NAME.toString(), loggingEvent.getLoggerName());
 headers.put(Log4jAvroHeaders.TIMESTAMP.toString(), String.valueOf(loggingEvent.timeStamp));
 headers.put(Log4jAvroHeaders.ADDRESS.toString(), clientAddress);
   String.valueOf(loggingEvent.getLevel().toInt()));
 if (loggingEvent.getMessage() instanceof Collection) {
  messages = (Collection) loggingEvent.getMessage();
 } else {
      loggingEvent.getNDC(), loggingEvent.getLocationInformation(),
      loggingEvent.getProperties());
    msg = layout.format(singleLoggingEvent);
   } else {

 for(int i = 0; i < len; i++) {
  sbuf.append(s[i]);

  }
 }
 // Normalize the log message level into the supported categories
 int nt_category = event.getLevel().toInt();
 // Anything above FATAL or below DEBUG is labeled as INFO.
 //if (nt_category > FATAL || nt_category < DEBUG) {
 //  nt_category = INFO;
 //}
