Spring keystore bean

In spring.application I've specified keystore name and password. I'd like to sign some data with Signature.sign() from java security, but to do that I'd need Keystore. Is there a way to get Spring managed keystore bean, or do I have to create my own keystore, even when it's already used by spring?

Spring Boot 2.4.x:

import java.io.IOException;
import java.security.KeyStore;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;
import java.security.cert.CertificateException;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.ClassPathResource;

@Configuration
public class KeyStoreConfiguration {

    private static final String KEY_STORE = "keystore.p12";
    private static final String KEY_STORE_TYPE = "PKCS12";
    private static final String KEY_STORE_PASSWORD = "password";
    
    @Bean
    public KeyStore keyStore() throws KeyStoreException, NoSuchAlgorithmException, CertificateException, IOException {
        KeyStore keyStore = KeyStore.getInstance(KEY_STORE_TYPE);
        keyStore.load(new ClassPathResource(KEY_STORE).getInputStream(), KEY_STORE_PASSWORD.toCharArray());
        
        return keyStore;
    }
}

You can just use the

@Autowired
private KeyStore keyStore;

if you've configured it correctly in your XML/Java configuration like so

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:crypt="http://springcryptoutils.com/schema/crypt"
   xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
                       http://springcryptoutils.com/schema/crypt http://springcryptoutils.com/schema/crypt.xsd">

    <crypt:keystore id="keystore"
                location="somePath}"
                password="somePassword"/>
</beans>
