我正在尝试使用Jedis使用Spring数据Redis将消息发布到通道.这是一个非常简单的Java配置:

@Bean(name="jedisConnectionFactory")
JedisConnectionFactory jedisConnectionFactory() {
    JedisConnectionFactory factory = new JedisConnectionFactory();
    factory.setHostName(redisHostName);
    factory.setPort(redisPort);
    factory.setUsePool(true);
    return factory;
}

@Bean(name="redisTemplate")
RedisTemplate<Object, Object> redisTemplate() {
    RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<Object, Object>();
    redisTemplate.setConnectionFactory(jedisConnectionFactory());
    return redisTemplate;
}

其中redisPort = 6379,redisHostName ="localhost".

当我运行以下测试时:

 @Test
public void testRedis(){
    ApplicationContext context = new AnnotationConfigApplicationContext(AppConfig.class);
    RedisTemplate<Object,Object> redisTemplate = (RedisTemplate<Object, Object>) context.getBean("redisTemplate");
    redisTemplate.convertAndSend("test", "123");
}

我得到以下stacktrace:

我正在尝试使用在本地主机上破坏的 Redis 服务器来保存我的会话实例。当我启动应用程序时，我收到一条错误消息，应用程序无法启动。看起来类无法找到或 bean 错误，但我不太明白错误消息。
