Java Log4j 2的Log4jNestedDiagnosticContextFilter

从Spring 4.2.1开始，

Log4jNestedDiagnosticContextFilter

在Apache对log4j 1.x的EOL声明之后被弃用，如下所示

我找到了相应的JIRA票（）但是如何将log4j2引入到Spring环境中，以实现与

log4jnestedagnosticcontextfilter

相同的功能？

我通过复制

log4jnestedagnosticcontextfilter

来实现它，并将记录器调整为log4j2，并将

NDC

更改为

ThreadContext

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.apache.logging.log4j.ThreadContext;
import org.springframework.web.filter.AbstractRequestLoggingFilter;

import javax.servlet.http.HttpServletRequest;

public class CustomRequestLoggingFilter extends AbstractRequestLoggingFilter {

  protected final Logger log4jLogger = LogManager.getLogger(getClass());

  @Override
  protected void beforeRequest(HttpServletRequest request, String message) {
    if (log4jLogger.isDebugEnabled()) {
      log4jLogger.debug(message);
    }
    ThreadContext.push(getNestedDiagnosticContextMessage(request));
  }

  @Override
  protected void afterRequest(HttpServletRequest request, String message) {
    ThreadContext.pop();
    if (ThreadContext.getDepth() == 0) {
      ThreadContext.removeStack();
    }
    if (log4jLogger.isDebugEnabled()) {
      log4jLogger.debug(message);
    }
  }

  protected String getNestedDiagnosticContextMessage(HttpServletRequest request) {
    return createMessage(request, "", "");
  }
}
