log4j信息级别和调试不起作用

Question

I am using log4j in a spring application. The bean creation & other information is being displayed correctly in the console & written on the disk but in the handler method the log.info & log.debug are not working. I see no output in the console. Can anyone tell me why?

log4j.properties

# Direct log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=C:\\logging.log
log4j.appender.file.MaxFileSize=1MB
log4j.appender.file.MaxBackupIndex=1
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

# Direct log messages to stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss.SSSS} %p %t %c \u2013 %m%n

# Root logger option
log4j.rootLogger=debug, file, stdout

ClinicController.java

package com.petclinic.controller;


//ClinicController is the generic controller for the web app
@Controller
public class ClinicController {

    @Autowired
    private ClinicService clinicService;

    private static Logger logger = LogManager.getLogger("ClinicController");


    //Custom Handler for the welcome Page
    @RequestMapping("/welcome")
    public String welcomeHandler(HttpServletRequest request)
    {
        logger.info(request.getServletPath());
        System.out.println("Inside Welcome Controller");
        System.out.println(request.getServletPath());
        logger.debug("Inside Clinic Controller Welcome Controller");
        return "welcome";
    }
}

I can see System.out statements in the console but not logger.info & debug.

logger.info(request.getServletPath());
logger.debug("Inside Clinic Controller Welcome Controller");

Am I missing something?

Answer 1

1.) Where is your log4j.properties file located? As you build a WAR, your log4j.properties file should be in the root of the WEB-INF/classes folder.

2.) As suggested by archie hicox, you should change rootlogger to log4j.rootLogger=debug, file, stdout (without info)
