Как настроить shiro.ini для пользовательской области в приложении spring-boot?

У меня есть свой Пользовательский мир

public class MyCustomRealm extends JdbcRealm  {
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) {
        // Custom code
    }
}

файл shiro.ini следующим образом:

jdbcRealm= com.company.security.shiro.realm.MyCustomRealm 
jdbcRealm.permissionsLookupEnabled = true
ds = com.mysql.jdbc.jdbc2.optional.MysqlDataSource
ds.serverName = jdbc:mysql://datasource
ds.user = user
ds.password = pass
jdbcRealm.dataSource=$ds
securityManager.realms = $jdbcRealm

Кто-нибудь знает, что нужно сделать, чтобы настроить/зарегистрировать shiro.ini для проекта spring-boot? или какая конфигурация требуется в файле SpringBootApp.java?

@Bean
public Realm realm() {
    Realm realm  = new IniRealm("classpath:shiro.ini");
    DefaultSecurityManager securityManager = new DefaultSecurityManager(realm);
    SecurityUtils.setSecurityManager(securityManager);
    return realm;
}

Использование вышеуказанного bean-компонента приводит к следующему исключению:
