项目开发过程中，需要整合redis，在整合过程中，出现了如下的错误：

Parameter 0 of method cacheManager in org.springframework.boot.autoconfigure.cache.RedisCacheConfiguration required a bean of type 'org.springframework.data.redis.core.RedisTemplate' that could not be found.
    	- Bean method 'redisTemplate' in 'RedisAutoConfiguration.RedisConfiguration' not loaded because @ConditionalOnMissingBean (names: redisTemplate; SearchStrategy: all) found bean 'redisTemplate'
    	- Bean method 'stringRedisTemplate' in 'RedisAutoConfiguration.RedisConfiguration' not loaded because @ConditionalOnMissingBean (types: org.springframework.data.redis.core.StringRedisTemplate; SearchStrategy: all) found bean 'stringRedisTemplate'
    
    
    Action:
    
    Consider revisiting the conditions above or defining a bean of type 'org.springframework.data.redis.core.RedisTemplate' in your configuration.

错误原因：

有两个同名的bean都叫redisTemplate，导致加载失败。

解决方法：

自定义的redisTemplate改名，如下：

@Bean(name = "redisTemplateCustomize")
    //    @ConditionalOnMissingBean(name = "redisTemplate")
        public RedisTemplate<String, Object> redisTemplateCustomize(
            @Qualifier("redisConnectionFactory") RedisConnectionFactory redisConnectionFactory)
            throws UnknownHostException
        {
            Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<Object>(
                Object.class);
            ObjectMapper om = new ObjectMapper();
            om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
            om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
            jackson2JsonRedisSerializer.setObjectMapper(om);
    
            RedisTemplate<String, Object> template = new RedisTemplate<String, Object>();
            template.setConnectionFactory(redisConnectionFactory);
            template.setKeySerializer(jackson2JsonRedisSerializer);
            template.setValueSerializer(jackson2JsonRedisSerializer);
            template.setHashKeySerializer(jackson2JsonRedisSerializer);
            template.setHashValueSerializer(jackson2JsonRedisSerializer);
            template.afterPropertiesSet();
            return template;
        }

使用时，如下：

@Autowired
        @Qualifier("redisTemplateCustomize")
        private RedisTemplate redisTemplate;
