Where to put the log4j.properties file in the spring boot application

Question

I created a file log4j.properties, and I placed it in the resources folder as a file application.properties, in this file I have this line: logging.config=log4j.propertiesthat indicated the name of my log4j properties file, but when I run my application, I get this error on my console:

Logging system failed to initialize using configuration from 'log4j.properties'
java.io.FileNotFoundException: C:\Users\***\Desktop\CapRecrute\log4j.properties (The system cannot find the file specified)

so I tried changing the property logging.configto src\\main\\resources\\log4j.properties, and then got another error:

java.lang.IllegalStateException: Could not initialize Logback logging from src\main\resources\log4j.properties ... Caused by: ch.qos.logback.core.LogbackException: Unexpected filename extension of file [file:/C:/Users/Aimad%20MAJDOU/Desktop/CapRecrute/src/main/resources/log4j.properties]. Should be either .groovy or .xml

in my pom file i have this:

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>

                </exclusion>
            </exclusions>
        </dependency>
        <dependency>

                </exclusion>
            </exclusions>
        </dependency>
