【问题描述】：

我有一个托管在 Heroku 上的基于 Spring 的 Java Web 应用程序。我正在尝试使用 Redis 实现来利用 Spring Caching 抽象。当服务器启动时，我收到一条错误消息：

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

这是我的配置：

@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;
}

这是完整的错误信息：

【解决方案1】：

当我升级到 Spring Data Redis v1.2.1-RELEASE 时遇到了完全相同的问题。我在将 Jedis 升级到最新版本 v2.4.2 后解决了这个问题。如果您使用的是 Maven，请检查以下依赖项。

<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>

希望这会有所帮助:)

您需要添加对 apache commons-pool2 库的引用。我在 Scala 项目中遇到了同样的问题——我们使用的是 sbt，所以这只是添加的一个例子：

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

当您使用 Java 时，您可能正在使用 Maven，所以我预计它可能更像这样（未经测试 - 用少许盐！）：

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

显然，这是JDK compiler bug #8006684

【解决方案4】：

如果有人因为从 Spring Boot 1.5.x 迁移到 2.x.x 而面临它，这里是 thread 来解释它。也请看这个link

现在使用 Lettuce 代替 Jedis 作为 Redis 驱动程序你使用 spring-boot-starter-data-redis。如果您使用更高级别 Spring Data 构造你应该会发现变化是透明的。

我们仍然支持 Jedis。如果您更喜欢 Jedis，请通过以下方式切换依赖项不包括 io.lettuce:lettuce-core 并添加 redis.clients:jedis 而是。

连接池是可选的，如果您正在使用它，您现在需要将 commons-pool2 自己添加为 Lettuce，与 Jedis 不同，不会带上它。
