nl.knowledgeplaza.util.jdbc
Class Connection

java.lang.Object
  nl.knowledgeplaza.util.jdbc.Connection

All Implemented Interfaces:

InvocationHandler

public class Connection
extends Object
implements InvocationHandler

This is for logging SQL statements to log4j. Use the wrap method to wrap a connection object and that is it. There are several levels of logging nl.knowledgeplaza.util.jdbc.Connection.sql - log all SQL related information, like create (prepared)statements, setting of parameters nl.knowledgeplaza.util.jdbc.Connection.rest - less interesting calls, like close nl.knowledgeplaza.util.jdbc.Connection.resultset - log the get actions against resultsets xnl.knowledgeplaza.util.jdbc.Connection.sqltrace - log a stack trace so the origin of the call can be traced
