Reflection-based suite of facades over Logger, that provides logging of complex objects.

Print Tool (print-tool) on GitHub

Overview
—————–

Some time, it’s necessary to save in log complex objects (VO, DTO, Entities and some other POJO).

The main features of Print Tool:

– facade over Logger, that allows to solve (using reflection) and print header and footer of output of some function; in this case you don’t need to care about name of function, if it has been renamed/re-factored;

private static final IPrintTool printTool = PrintTool.getPrintToolInstance(LoggerFactory.getLogger(TestPrintTool.class));

public void testPrintTool() {
	printTool.debug(PrintSfx.SFX_IN);
	// some code here
	printTool.debug(PrintSfx.SFX_OUT);
}
 

– provides solving of all fields of complex objects (including aggregated objects) and print values of all fields; in this case you need to use only:

IpVO ipVO;
AddressReqVO addressReqVO;

// init of objects ipVO and addressReqVO

printTool.info(ipVO);
printTool.info(addressReqVO);

– provides interface, that allow to override print of complex objects
(please, see interface com.smansoft.tools.print.api.IPrintable in sources);

As result, usage of Print Tool in function:

private static final IPrintTool printTool = PrintTool.getPrintToolInstance(LoggerFactory.getLogger(TestPrintTool.class));

@Test
public void testPrintTool() {
	printTool.debug(PrintSfx.SFX_IN);

	printTool.info(ipVO);
	printTool.info(addressReqVO);

	printTool.debug(PrintSfx.SFX_OUT);
	Assert.assertTrue(true);
}

generates follow log output:
print-tool-tests.log
