ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console.

Error: the status logger did not find the log4j2 configuration file and will use the default configuration: log errors only to the console.

Reason: the jar package of log4j2 is log4j2 provided by the hibernate 5 framework. Even if you import a third-party log package in SSH, the system will still call log4j2. The default configuration file is log4j2.xml

Solution: add profile log4j2.xml

<?xml version="1.0" encoding="UTF-8"?>

<Configuration status="warn">
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%m%n" />
        </Console>
    </Appenders>
    <Loggers>
        <Root level="INFO">
            <AppenderRef ref="Console" />
        </Root>
    </Loggers>
</Configuration>

After configuring log4j2, hibernate will output clearer information to the console. When it is set to status = “warn”, you will see various detailed internal outputs of log4j2.

Log4j2.xml can be placed anywhere. As long as you finally put it in the classpath, create a new resources directory in the above project to place log4j2.xml. If you try to run without adding the classpath, an error will be reported.
