Jooq无法记录SQL查询

Question

I am using Jooq along with JAX-RS to create a REST API. I have the following dependencies in my maven pom file log4j 1.2.7 and jooq 3.9.4 I have put the log4j.properties file in resources folder. Here are the contents of the file:

log4j.rootLogger=DEBUG, stdout, file
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

log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=/home/ps06756/log4j-application.log
log4j.appender.file.MaxFileSize=5MB
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

Still, Jooq is not logging the SQL statemennts being executed. How should I correct this problem.

Answer 1

Please check if you have logback or slf4j on your classpath as that is the first logger the JooqLogger tries to find on the classpath. If it fails it tries log4j and after that it falls to java.util.logger .

When it does find logback or slf4j but you don't have any configuration you will not see anything being logged.
