JedisPoolConfig is not assignable to GenericObjectPoolConfig

Question

I have a Spring based java web application hosted on Heroku. I am attempting to utilize the Spring Caching abstraction using the Redis implementation. When the server starts, I get an error saying:

Type 'redis/clients/jedis/JedisPoolConfig' (current frame, stack[3]) is not assignable to 'org/apache/commons/pool2/impl/GenericObjectPoolConfig'

Here is my configuration:

@Bean
     RedisConnectionFactory jedisConnectionFactory() throws Exception {
         URI redisUri =  new URI(System.getenv("REDISCLOUD_URL"));
         JedisConnectionFactory redisConnectionFactory = new JedisConnectionFactory();
         redisConnectionFactory.setHostName(redisUri.getHost());
         redisConnectionFactory.setPort(redisUri.getPort());
         redisConnectionFactory.setPassword(redisUri.getUserInfo().split(":",2)[1]);
         redisConnectionFactory.setUsePool(true);
         return redisConnectionFactory;
     }

 @Bean
 RedisTemplate<Object, Object> redisTemplate()  {
     RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<Object, Object>();
     try {
        redisTemplate.setConnectionFactory(jedisConnectionFactory());
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
     return redisTemplate;
 }
@Override
@Bean
public CacheManager cacheManager() {
    // configure and return an implementation of Spring's CacheManager SPI
    RedisCacheManager manager = new RedisCacheManager(redisTemplate());
    List<String> caches = new ArrayList<String>();
    caches.add("Suppliers");
    caches.add("Manufacturer");
    caches.add("Sheeting");
    caches.add("SignTypeFlat");
    manager.setCacheNames(caches);
    return manager;
}

Here is the entire Error Message:

Any help would be greatly appreciated.

Answer 1

Had exactly the same problem when I upgraded to Spring Data Redis v1.2.1-RELEASE. I solved the problem after upgrading Jedis to the latest version - v2.4.2. If you are using Maven, check the following dependencies.

<properties>
    <spring.data.redis>1.2.1.RELEASE</spring.data.redis>
    <jedis>2.4.2</jedis>
</properties>

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-redis</artifactId>
    <version>${spring.data.redis}</version>
</dependency>
<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>${jedis}</version>
</dependency>

Hope this helps :)

You need to add a reference to the apache commons-pool2 library. I had the same problem in a Scala project - we were using sbt, so it was just a case of adding:

"org.apache.commons" % "commons-pool2" % "2.0"

As you're using Java, you might be using Maven, so I would expect it's probably more like this (untested - take it with a pinch of salt!):

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-pool2</artifactId>
    <version>2.0</version>
</dependency>

Answer 3

Apparently, this is a JDK compiler bug #8006684

Answer 4

In case someone facing it due to migration from Spring Boot 1.5.x to 2.x.x here is thread that explains it. Also please see this link

Lettuce is now used instead of Jedis as the Redis driver when you use spring-boot-starter-data-redis. If you are using higher level Spring Data constructs you should find that the change is transparent.

We still support Jedis. Switch dependencies if you prefer Jedis by excluding io.lettuce:lettuce-core and adding redis.clients:jedis instead.

Connection pooling is optional and, if you are using it, you now need to add commons-pool2 yourself as Lettuce, contrary to Jedis, does not bring it transitively.
