I. Introduction
Normally, developers need to output certain information to the backend when debugging to check if the program runs as expected, or logging certain user actions. These scenarios include the output of executed SQL queries when using a report, as well as the time consumption in every stage of the report generation for analytic purposes. In these cases, developers can carry out the process with FineLoggerFactory.getLogger(). level(msg).
Three levels, namely, info, warning and error, are provided to output with. Note that only when the set level is of lower or the same grade as the applied one can the corresponding information be output successfully.
Note: FineReport JARs should be included beforehand.
