Package com.nuodb.jdbc.logger

Class StandardLogger

java.lang.Object

com.nuodb.jdbc.logger.StandardLogger

All Implemented Interfaces:

Logger

public class StandardLogger
extends Object
implements Logger

Logger is used to print messages to the standard JDBC log writer set through DriverManager.setLogWriter(PrintWriter) or custom log writer. The logger has a "level" associated with it and is set to info by default, OFF level disables log messages. Other valid log levels are:

• ERROR
• WARN
• INFO
• DEBUG
• TRACE

Log messages are printed to the underlying log writer and formatted using provided message pattern. Message pattern can include several placeholders, which will be expanded in runtime:

• %level outputs log level
• %date(dateFormatStyle,default=yyyy-MM-dd HH:mm:ss.SSS) produces current timestamp formatted to custom style or default one yyyy-MM-dd HH:mm:ss.SSS, if custom style is not set
• %line(short|long|or custom format built from any combination of {className}, {methodName}, {shortClassName}, {lineNumber} placeholders) outputs stack trace element
• %message prints original message

Messages are formatted according to [%date(yyyy-MM-dd HH:mm:ss.SSS)] (%level) (%line(long)) - %message pattern by default.
