Logger in slf4j, could you explain and give explain on how to use it? (e.g. how to see where the log is)
So Like any logger library we have a configuration file where we place the locationof logs it can be DB text file Console out put DEbugger on statments
Logger in slf4j, could you explain and give explain on how to use it? (e.g. how to see where the log is)
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
private final Logger log = LoggerFactory.getLogger(getClass());
log.info(ex.getMessage());
Using slf4j with Simple logger
Create a Maven based project and this in your pom.xml.
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.5</version>
</dependency>
Now you may use Logger in your Java code like this.
package deng;
import org.slf4j.*;
public class Hello {
static Logger LOGGER = LoggerFactory.getLogger(Hello.class);
public static void main(String[] args) {
for (int i = 0; i < 10; i++)
if (i % 2 == 0)
LOGGER.info(“Hello {}”, i);
else
LOGGER.debug(“I am on index {}”, i);
}
}
The above will get your program compiled, but when you run it, you will see these output.
bash> java deng.Hello
SLF4J: Failed to load class “org.slf4j.impl.StaticLoggerBinder”.
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
What it’s saying is that at runtime, you are missing the logging “implementation” (or the logger binding), so slf4j simply use a “NOP” implmentation, which does nothing. In order to see the output properly, you may try use an simple implementation that does not require any configuration at all! Just go back to your pom.xml and add the following:
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>1.7.5</version>
</dependency>
Now you see logging output on STDOUT with INFO level. This simple logger will default show any INFO level message or higher. In order to see DEBUG messages, you would need to pass in this System Property -Dorg.slf4j.simpleLogger.defaultLogLevel=DEBUG at your Java startup.
Using slf4j with Log4j logger
Now we can experiment and swap different logger implementations, but your application code can remain the same. All we need is to replace slf4j-simple with another popular logger implementation, such as the Log4j.
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.7.5</version>
</dependency>
Again, we must configure logging per implementation that we picked. In this case, we need an
src/main/resources/log4j.properties file.
log4j.rootLogger=DEBUG, STDOUT
log4j.logger.deng=INFO
log4j.appender.STDOUT=org.apache.log4j.ConsoleAppender
log4j.appender.STDOUT.layout=org.apache.log4j.PatternLayout
log4j.appender.STDOUT.layout.ConversionPattern=%5p [%t] (%F:%L) – %m%n
src/main/resources/log4j.properties file for writing into file and stdout
# Root logger option
log4j.rootLogger=INFO, file, stdout
# 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=10MB
log4j.appender.file.MaxBackupIndex=10
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-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} %-5p %c{1}:%L - %m%n
Re-run your program, and you should see similar output.
Using slf4j with JDK logger
The JDK actually comes with a logger package, and you can replace pom.xml with this logger implementation.
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-jdk14</artifactId>
<version>1.7.5</version>
</dependency>
Now the configuration for JDK logging is a bit difficult to work with. Not only need a config file, such as src/main/resources/logging.properties, but you would also need to add a System properties -Djava.util.logging.config.file=logging.properties in order to have it pick it up. Here is an example to get you started:
.level=INFO
handlers=java.util.logging.ConsoleHandler
java.util.logging.ConsoleHandler.level=FINEST
deng.level=FINEST
Using slf4j with Logback logger
The logback logger implementation is a super dupa quality implementation. If you intend to write serious code that go into production, you may want to evaluate this option. Again modify your pom.xml to replace with this:
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.0.13</version>
</dependency>
Here is a sample of configuration src/main/resources/logback.xml to get things started.
<configuration>
<appender name=”STDOUT” class=”ch.qos.logback.core.ConsoleAppender”>
<encoder>
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} – %msg%n</pattern>
</encoder>
</appender>
<logger name=”deng” level=”DEBUG”/>
<root level=”INFO”>
<appender-ref ref=”STDOUT” />
</root>
</configuration>
for db logging
with
slf4j-api-1.7.5.jar
The next step was to change logback.xml file:
<?xml version="1.0" encoding="UTF-8"?> <configuration> <appender name="stdout" class="ch.qos.logback.core.ConsoleAppender"> <!-- encoders are assigned the type ch.qos.logback.classic.encoder.PatternLayoutEncoder by default --> <encoder> <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{5} - %msg%n </pattern> </encoder> </appender> <appender name="db" class="ch.qos.logback.classic.db.DBAppender"> <connectionSource class="ch.qos.logback.core.db.DriverManagerConnectionSource"> <driverClass>org.postgresql.Driver</driverClass> <url>jdbc:postgresql://localhost:5432/simple</url> <user>postgres</user> <password>root</password> <!-- no password --> </connectionSource> </appender> <!-- the level of the root level is set to DEBUG by default. --> <root level="TRACE"> <appender-ref ref="stdout" /> <appender-ref ref="db" /> </root> </configuration>
As seen here, I have created two appenders – a console appender and a database appender.
The database appender here requires the JDBC driver, the jdbc url and the db credentials. An additional property is the connectionSource which is actually the type of Connection wrapper that we would like to use. Logback provides a few options here and I went with the DriverManagerConnectionSource class.
The next step was to write a test class to test the code:
public class SampleTestDbAppender { private static final Logger logger = LoggerFactory.getLogger(TestDbAppender.class); public SampleTestDbAppender () { logger.info("Class instance created at {}", DateFormat.getInstance().format(new Date()));
} public void doTask() { logger.trace("In test doTask"); logger.trace("doTask test complete"); } public static void main(String[] args) { logger.warn("Running test code..."); new TestDbAppender().doTask(); logger.debug("test Code execution complete."); } }
