我正在尝试使用Jedis使用Spring数据Redis将消息发布到 channel 。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和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");
}

我得到以下堆栈跟踪:

最佳答案

此问题是由与 Spring 数据Redis(1.5.0.RELEASE)不兼容的Jedis版本(2.7.2)引起的。我花了3天的时间来面对同样的问题,然后才能从这篇文章和评论中得到启发。 Jedis版本(2.6.2)可以正常工作(尽管我在程序中遇到了其他错误,但至少比同一个错误消息有一些进步)!

谢谢。
