How do I disable logging output from Hibernate for:
HHH000262: Table not found: ...
I have the following log4j.properties:
log4j.rootLogger=WARN, stdout, stderr
log4j.logger.org.apache=WARN
log4j.logger.org.springframework=WARN
log4j.logger.org.hibernate=ERROR
log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Threshold = TRACE
log4j.appender.stdout.Target = System.out
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern = %m%n
log4j.appender.stdout.filter.filter1=org.apache.log4j.varia.LevelRangeFilter
log4j.appender.stdout.filter.filter1.levelMin=TRACE
log4j.appender.stdout.filter.filter1.levelMax=INFO
# configure stderr for ERROR and WARN
log4j.appender.stderr = org.apache.log4j.ConsoleAppender
log4j.appender.stderr.Threshold = WARN
log4j.appender.stderr.Target = System.err
log4j.appender.stderr.layout = org.apache.log4j.PatternLayout
log4j.appender.stderr.layout.ConversionPattern = %p: %m%n
The log4j.logger.org.hibernate=ERROR does eliminate other Hibernate INFO messages such as opening the database and such. The "Table not found" messages are logged as INFO (I confirmed in the source code of hibernate).
I do not want to see the "Table not found" messages because I am using "update" mode to auto-create and update the tables.
What am I missing?
It looks like there is a bug in the org.hibernate.tool.hbm2ddl.DatabaseMetadata LOG static constant. It is constructed like so...
private static final CoreMessageLogger LOG = Logger.getMessageLogger(CoreMessageLogger.class, DatabaseMetaData.class.getName());
The subtle bug is that the value passed into the category parameter is the DatabaseMetaData class (notice the capital D in MetaData), which is from the package java.sql. As a result, you have to specify the logging level using...
log4j.logger.java.sql.DatabaseMetaData=WARN
In Log4j you can specify a logging level for specified package, class or logger identified by string. You just simply write this in log4j.properties file:
log4j.logger.<your package> = DEBUG|INFO|OFF|WARN...

Here is my log4j.properties file

log4j.category.successLogger=DEBUG, success
log4j.additivity.successLogger=false
log4j.category.failureLogger=WARN, failure
log4j.additivity.failureLogger=false
and in java class I'm using it as:
static final Logger successLog = Logger.getLogger("successLogger");
static final Logger failureLog = Logger.getLogger("failureLogger");
and using it as:
successLog.warn("Connection is not established");
failureLog.error("Exception",e);
I'm able to get success.log and failure.log file but I was not able to print it on console. Right now, I need to print it on console as well (as just as the flow of our program i.e., need to print parallelly on console while writing to respective logs) and in future I may require only to print the statements only which are eligible to write into success.log
How can I achieve it ???? Thanks in advance
By default Log4j uses the appenders explicitly configured for a logger and the appenders of the parent logger. This behavior is called "additivity" by Log4j. You disabled it with the lines:
log4j.additivity.successLogger=false
log4j.additivity.failureLogger=false
You just need to restore additivity by deleting these lines or setting the value to true.
Alternatively, you can list multiple appenders for a given logger:
log4j.category.successLogger=DEBUG, success, toConsole
I am trying to log my events in my database using log4j2. Specifically I am using log4j2 jdbc appender in my properties configuration file for that purpose. By using default log4j2 log levels everything works. The log values successfully get inserted in database.
This is my initial appender in my log4j2 properties file:
# JDBC appender
appender.db.type = Jdbc
appender.db.name = databaseAppender
appender.db.tableName = db_name.test
appender.db.cf.type = ConnectionFactory
appender.db.cf.class = com.myproject.ConnectionFactory
appender.db.cf.method = getConnection
appender.db.col2.type = Column
appender.db.col2.name = message
appender.db.col2.pattern = %m
appender.db.col3.type = Column
appender.db.col3.name = category
appender.db.col3.pattern = %M{1}
appender.db.col4.type = Column
appender.db.col4.name = timestamp
appender.db.col4.isEventTimestamp = true
appender.db.col5.type = Column
appender.db.col5.name = log_level
appender.db.col5.pattern = %-5p
appender.db.filter.threshold.type = ThresholdFilter
appender.db.filter.threshold.level = info
appender.db.filter.threshold.onMatch = Accept
appender.db.filter.threshold.onMismatch = Deny
But then I tried to create a custom log level following this log4j2 site https://logging.apache.org/log4j/2.x/manual/customloglevels.html
LOG.log(Level.forName("DIAG", 350), "a diagnostic message");
It successfully logs the event with the defined log level. And even places the data in database since threshold level is info in my jdbc appender. As info intLevel > diag intLevel.
My problem is if I changed the threshold level to diag in my jdbc appender it doesn't work at all i.e.
appender.db.filter.threshold.level = diag
Nothing is inserted in my database. So my first question is why it is not working and please give me any solution if possible.
Another thing is that I twitched around the intLevel of DIAG to 10 like:
LOG.log(Level.forName("DIAG", 10), "a diagnostic message");
And now it is inserting in database but also throws some errors.

Any help would be greatly appreciated and thank you in advance.
Since you have not defined intLevel in log4j2.properties file so add
customLevel.DIAG =350
where 350 is the intLevel.
This may remove the error.
I have simplified tomcat's logging properties to just this:
handlers = java.util.logging.ConsoleHandler
java.util.logging.ConsoleHandler.level = FINE
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter
java.util.logging.SimpleFormatter.format=%1$tF %1$TT.%1tL [::] %4$s %3$s %5$s %n
org.springframework.aop.framework.CglibAopProxy.level = ERROR
My issue is that the last line seems to be completely ignored and I keep seeing logs like this:
2018-05-09 10:40:33.159 [::] INFO org.springframework.aop.framework.CglibAopProxy
I am absolutely sure it comes from this logger thanks to the log format I set in the logging.properties.
My issue is that the last line seems to be completely ignored...
It is ignored because ERROR fails to be parsed as valid level. Per the docs:
Valid values are integers between Integer.MIN_VALUE and Integer.MAX_VALUE, and all known level names. Known names are the levels defined by this class (e.g., FINE, FINER, FINEST), or created by this class with appropriate package access, or new levels defined or created by subclasses.
Change your logging line to one of the valid levels that is higher than INFO. Choose one of the following log lines:
org.springframework.aop.framework.CglibAopProxy.level = OFF
org.springframework.aop.framework.CglibAopProxy.level = SEVERE
org.springframework.aop.framework.CglibAopProxy.level = WARNING
Here is what i have in my java code
private static final Logger SUCCESS = LogManager.getLogger("success");
private static final Logger ERROR = LogManager.getLogger("error");
And I need to create 2 log files for these logs. (i tried to follow Creating multiple log files of different content with log4j) but I think its not exactly the same. But here goes what i created in log4j.properties.
log4j.rootLogger=TRACE, SuccessAppender, ErrorAppender
# setup SuccessAppender
log4j.appender.SuccessAppender=org.apache.log4j.RollingFileAppender
log4j.appender.SuccessAppender.Threshold=INFO
log4j.appender.SuccessAppender.File=success.log
log4j.appender.SuccessAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.SuccessAppender.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
# setup ErrorAppender
log4j.appender.ErrorAppender=org.apache.log4j.RollingFileAppender
log4j.appender.ErrorAppender.Threshold=INFO
log4j.appender.ErrorAppender.File=error.log
log4j.appender.ErrorAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.ErrorAppender.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
I was wondering how to map this "success" log into the "SuccessAppender".
First of all you have to make sure that the RootLogger is not logging anything. This can be achieved in different ways but my first solution is to let it append to the NullAppender.
log4j.rootLogger=OFF, NullAppender
# setup NullAppender
log4j.appender.NullAppender=org.apache.log4j.varia.NullAppender
Then you'll have to set the log level and the appender for your loggers (success and error):
log4j.logger.success = TRACE, SuccessAppender
log4j.logger.error = TRACE, ErrorAppender
And the rest of your log4j.properties is left as is.
An alternate solution if you don't want to use the NullAppender would be to set the additivity flag on the loggers:
log4j.rootLogger=OFF, SuccessAppender, ErrorAppender
log4j.logger.success = TRACE, SuccessAppender
log4j.additivity.success = false
log4j.logger.error = TRACE, ErrorAppender
log4j.additivity.error = false
Some more information about the additivity can be found in the Log4J manual.
Appender Additivity
The output of a log statement of logger C will go to all the appenders in C and its ancestors. This is the meaning of the term "appender additivity".
However, if an ancestor of logger C, say P, has the additivity flag set to false, then C's output will be directed to all the appenders in C and its ancestors upto and including P but not the appenders in any of the ancestors of P.
Loggers have their additivity flag set to true by default.
try
log4j.logger.success=TRACE, SuccessAppender
I want to read data from .properties file using slf4j,T i am able to output the data on console but what i want is to output the data on some file so i need file Appender for this which is declared in .properties file and i am not able to read the .properties file using slf4j.Can anyone help.
PS:I need an example that explains how to use.properties file in slf4j and how to initialize logger factory for that.
See http://slf4j.org/faq.html.
SLF4J is only a facade, meaning that it does not provide a complete
logging solution. Operations such as configuring appenders or setting
logging levels cannot be performed with SLF4J.
slf4j-simple doesn't provide extra configuration features at all.
For other implementations you should use the way to configure they provide.
For example, log4j.properties for slf4j-log4j. See http://logging.apache.org/log4j/1.2/manual.html#Configuration.
If using log4j, alternatively it can be used "Log4jLoggerAdapter", defining the configuration on a .properties file.
Code below.
The required jars:
slf4j-api-1.7.5.jar
slf4j-log4j12-1.7.5.jar
If desired the source code (useful when debugging):
slf4j-api-1.7.5-sources.jar
slf4j-log4j12-1.7.5-sources.jar
The testing java class:
import org.apache.log4j.PropertyConfigurator;
import org.slf4j.LoggerFactory;
import org.slf4j.impl.Log4jLoggerAdapter;
public class Slf4j_log4j_main {
private static Log4jLoggerAdapter log = (Log4jLoggerAdapter) LoggerFactory.getLogger(Slf4j_log4j_main.class);
public static void main(String[] args) {
PropertyConfigurator.configure(Slf4j_log4j_main.class.getClassLoader().getResource("basic/log4j.properties"));
log.debug( "a debug" );
log.info( "an info" );
log.warn("a warn");
log.error("an error");
//log.fatal("a fatal"); // slf4j misses fatal log.
log.trace("a fatal");
System.out.println("");
System.out.println("[INFO]: done");
}
}

slf4j is an API - if you consider it to consist only of interfaces and no classes, you are not far off.
The behavior you need is in the implementation of the interfaces, which for slf4j may be logback, AVSL, JDK14 (java.util.logging), log4j or Simple. Some can read properties, some cannot.
For logback you can use
<property file="src/main/java/chapters/configuration/variables1.properties" />
See http://logback.qos.ch/manual/configuration.html#definingProps for details.
