Spring Data Redis on Spring Boot 2.1.0 and Java 11 not working - spring

Question

I updated my application to Spring Boot 2.1.0 and Java 11. Since then my Redis is not working anymore.
When I call findById() and the result is empty then there are no problems.
When I call findById() and there is a result then the application / thread is stuck at this point and nothing happens.
When I use Spring Boot 2.0.6 and Java 9 the same code is working well.
I tried to use LettuceConnectionFactory and JedisConnectionFactory with the same result.
My Redis Config:
#Configuration
#EnableRedisRepositories
public class RedisConfiguration {
#Bean
RedisConnectionFactory connectionFactory() {
return new LettuceConnectionFactory();
}
#Bean
#Primary
RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory connectionFactory) {
RedisTemplate<String, Object> template = new RedisTemplate<>();
template.setConnectionFactory(connectionFactory);
template.setKeySerializer(new StringRedisSerializer());
template.setValueSerializer(new GenericJackson2JsonRedisSerializer());
return template;
}
}
My entity:
#Value
#RedisHash("token")
public class Token {
#Id
private String key;
private String value;
#TimeToLive
private Long expiration;
}
My repository just extends the CrudRepository and I'm only using provided methods.
Redis-Server version is Redis server v=4.0.9 running on OSX (dev) / Ubuntu (test).
Did I miss some changes I have to apply to use Java 11 / Boot 2.1 ?

Answer 1

Change the name of variable key to id.
There is a bug that makes the field with the #Id annotation have to be named id.
public class Token implements Serializable {
#Id private String id;
private String code;
#TimeToLive private Long expiration;
}

Answer 2

I found a solution. I created a test project and saw that the following exception was thrown by the CrudRepository#findById() method.
Caused by: org.springframework.data.keyvalue.core.UncategorizedKeyValueException: No accessor to set property #org.springframework.data.redis.core.TimeToLive(unit=SECONDS)private final java.lang.Long com.test.redisbug.Token.expiration!; nested exception is java.lang.UnsupportedOperationException: No accessor to set property #org.springframework.data.redis.core.TimeToLive(unit=SECONDS)private final java.lang.Long com.test.redisbug.Token.expiration!

I changed the #Value annoation on my entity to #Data #AllArgsConstructor and now it's working fine.
Seems like there were some changes in spring-data-redis.

Answer 3

I just had the same error and came to the solution by setting val to var in my kotlin model. I didn't use #value or #Data or #AllArgsConstructor.
#RedisHash("keys")
class Token (
#Id
val key: String? = null,
#TimeToLive
var expiration: Long
)
my logs looked like this:
org.springframework.data.keyvalue.core.UncategorizedKeyValueException: No accessor to set property #org.springframework.data.redis.core.TimeToLive(unit=SECONDS)private final long oauth2demo.oauth2clientdemo.Token.expiration!; nested exception is java.lang.UnsupportedOperationException: No accessor to set property #org.springframework.data.redis.core.TimeToLive(unit=SECONDS)private final long oauth2demo.oauth2clientdemo.Token.expiration!
