Class LoggerPrintWriter

java.lang.Object

java.io.Writer

java.io.PrintWriter

org.apache.logging.log4j.io.LoggerPrintWriter

All Implemented Interfaces:

Closeable, Flushable, Appendable, AutoCloseable

public class LoggerPrintWriter
extends PrintWriter

Logs each line written to a pre-defined level. Can also be configured with a Marker. This class provides an interface that follows the PrintWriter methods in spirit, but doesn't require output to any external writer.

Integration with JDBC logging can be as simple as:

     PrintWriter pw = IoBuilder.forLogger().setLevel(Level.DEBUG).buildPrintWriter();
     DriverManager.setLogWriter(pw);
     DataSource ds = ...
     ds.setLogWriter(pw);
