Description
Tested with Spring Boot 2.4.4:
When accessing REDIS through an transactional RedisTemplate from within a REST Controller, the call fails with the following exception:
java.lang.IllegalArgumentException: non-public interface is not defined by the given loader

Controller:
@RestController
class DemoController(
private val redisTemplate: RedisTemplate<String, String>
) {
@GetMapping("/")
@Transactional
fun root(): String {
val value = Instant.now().toString()
redisTemplate.opsForValue().set("Value", value)
return value
}
}Configuration:
@SpringBootApplication
class RedisIssueDemoApplication {
@Bean
fun redisConnectionFactory() = LettuceConnectionFactory()
@Bean
fun redisTemplate(redisConnectionFactory: RedisConnectionFactory) = RedisTemplate<String, String>().apply {
setConnectionFactory(redisConnectionFactory)
setEnableTransactionSupport(true)
afterPropertiesSet()
}
}When using Spring Boot 2.4.4 and accessing http://127.0.0.1:8080, the exception above is thrown.
Running the same controller with Spring Boot 2.4.0 works without issues
