JedisPoolConfig is not assignable to GenericObject

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.

Thanks!

Answer 1

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 2

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 :)

Apparently, this is a JDK compiler bug #8006684
