Class LoggingJdbcDriver
java.lang.Object
|
+--ahc.jdbc.logger.LoggingJdbcDriver
- All Implemented Interfaces:
- java.sql.Driver
- public class LoggingJdbcDriver
- extends java.lang.Object
- implements java.sql.Driver
This class is a JDBC driver that acts as a wrapper around an arbitrary other JDBC driver and logs all
calls made to that driver to System.out
. It can be used in any way that other JDBC drivers
can be used.
The URL is jdbclog:<driver class>:<driver URL>
- driver class: the fully qualified class name of the "real" JDBC driver to which the calls are forwarded
and that actually executes them.
- driver URL: the URL that you would normally use for the JDBC driver. For DB/2, this could be something
like jdbc:db2:test
Putting it all together, the URL could be something like
jdbclog:COM.ibm.db2.jdbc.app.DB2Driver:jdbc:db2:test
.
In the logging output, every "real" object that is returned by a JDBC call (i.e. something like a Connection
or a ResultSet rather than a String, Date or Timestamp) is associated with a unique ID. Whenever a call is
made, the ID is logged for the object on which the call is made. That allows you to trace what calls
are made on which objects in which sequence.
Note: This logging is very verbose. It is meant for tracking down some rather nasty bugs. When you
use it, make sure that you redirect System.out to a file.
