Can't get Spring AOP to log/print in my application

Like the title says, here are my classes (this is just for testing if I can AOP to work):

ApplicationContextConfiguration.kt

package com.fdev.jobby

import org.springframework.context.annotation.Bean
import org.springframework.context.annotation.ComponentScan
import org.springframework.context.annotation.Configuration
import org.springframework.context.annotation.EnableAspectJAutoProxy

@Configuration
@ComponentScan
@EnableAspectJAutoProxy
class ApplicationContextConfiguration {

    @Bean
    fun dataSource():DataSource{
        return DataSource()
    }
}

DataSource.kt

package com.fdev.jobby

open class DataSource {
    fun getDataFromDB(): String{
        // fetching Data
        return "data was loaded"
    }

    fun insertDataToDB(){
        // inserting Data
    }
}

LoggingDataSource.kt

package com.fdev.jobby

import mu.KotlinLogging
import org.aspectj.lang.annotation.AfterReturning
import org.aspectj.lang.annotation.AfterThrowing
import org.aspectj.lang.annotation.Aspect
import org.aspectj.lang.annotation.Before
import org.aspectj.lang.annotation.Pointcut
import org.springframework.stereotype.Component

@Aspect
@Component
class LoggingDataSource {
    private val logger = KotlinLogging.logger {}

    @Pointcut("execution(* com.fdev.jobby.DataSource.*(..))")
    fun getAllMethods(){}

    @Before("getAllMethods()")
    fun startOfAccessToDB(){
        logger.error("Starting access to DB")
    }

    @AfterReturning("getAllMethods()")
    fun endOfAccessToDBSuccess(){
        println("Successful access to DB..")
    }

    @AfterThrowing("getAllMethods()")
    fun endOfAccessToDBFailure(){
        println("Failed access to DB..")
    }
}

AOPController.kt

package com.fdev.jobby

import org.springframework.beans.factory.annotation.Autowired
import org.springframework.web.bind.annotation.GetMapping
import org.springframework.web.bind.annotation.RequestMapping
import org.springframework.web.bind.annotation.RestController

@RestController
@RequestMapping("aop")
class AOPController(@Autowired val dataSource: DataSource) {

    @GetMapping("testing")
    fun aopTesting(): String{
        val data = dataSource.getDataFromDB()
        return data
    }
}

So when I call localhost:8080/aop/testing it shows the string "data was loaded" but it wont log or print my advices. What am I doing wrong? I have been reading here but the docs seem very unintuitive and not helpful at all. Please help :(

Edit: my gradle dependencies look like this

dependencies {
    implementation("org.springframework.boot:spring-boot-starter-web")
    implementation("com.fasterxml.jackson.module:jackson-module-kotlin")
    implementation("org.jetbrains.kotlin:kotlin-reflect")
    implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8")
    implementation("org.springframework.boot:spring-boot-starter")
    implementation("org.springframework.boot:spring-boot-starter-aop")
    implementation("io.github.microutils:kotlin-logging-jvm:2.1.20")
    testImplementation("org.springframework.boot:spring-boot-starter-test")
}
