How to call https url using spring boot 3

Question

I try to configure restTemplate to call https url in spring boot 3 but that does not compile. For this i use import org.apache.http.impl.client.HttpClients import org.apache.http.ssl.SSLContexts and the code below :

fun restTemplate(): RestTemplate {
        val restTemplate = RestTemplate()

        // Load the .p12 file from the test resources directory
        val p12File = ClassPathResource("certs/clientErfin2.p12").file
        val p12Stream = FileInputStream(p12File)

        try {
            // Load the .p12 file into a KeyStore
            val keyStore = KeyStore.getInstance("PKCS12")
            keyStore.load(p12Stream, "password".toCharArray())

            // Create an SSL context with the KeyStore
            val sslContext = SSLContexts.custom()
                    .loadKeyMaterial(keyStore, "password".toCharArray())
                    .build()

            // Create an HttpClient with the SSL context
            val httpClient = HttpClients.custom()
                    .setSSLContext(sslContext)
                    .build()

            // Create a ClientHttpRequestFactory with the HttpClient
            val requestFactory: ClientHttpRequestFactory = HttpComponentsClientHttpRequestFactory(httpClient)

            // Set the ClientHttpRequestFactory on the RestTemplate
            restTemplate.requestFactory = requestFactory
        } finally {
            p12Stream.close()
        }

        return restTemplate
    }

the line val requestFactory: ClientHttpRequestFactory = HttpComponentsClientHttpRequestFactory(httpClient) does not compile because of Cannot access class 'org.apache.hc.client5.http.classic.HttpClient'. Check your module classpath for missing or conflicting dependencie. How can i fix this?

Thank's!

i tried to add the dependency hc.client5 and that does not resolve the problem
