spring-boot整合redis启动项目报错，信息如下：  
`defining a bean of type 'org.springframework.data.redis.core.RedisTemplate' in your configuration.`  
或`Consider defining a bean of type 'org.springframework.data.redis.core.StringRedisTemplate' in your configuration.`

修改pom文件  
将

<dependency>
                <groupId>org.springframework.data</groupId>
                <artifactId>spring-data-redis</artifactId>
            </dependency>

`修改为`

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-data-redis</artifactId>
            </dependency>

*  修改完成后，如果想自定义RedisTemplate可参考如下配置

@Bean
        public RedisTemplate<String, Object> template(RedisConnectionFactory factory) { 
            // 创建RedisTemplate<String, Object>对象
            RedisTemplate<String, Object> template = new RedisTemplate<>();
            // 配置连接工厂
            template.setConnectionFactory(factory);
            // 定义Jackson2JsonRedisSerializer序列化对象
            Jackson2JsonRedisSerializer<Object> jacksonSeial = new Jackson2JsonRedisSerializer<>(Object.class);
            ObjectMapper om = new ObjectMapper();
            // 指定要序列化的域，field,get和set,以及修饰符范围，ANY是都有包括private和public
            om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
            // 指定序列化输入的类型，类必须是非final修饰的，final修饰的类，比如String,Integer等会报异常
            om.activateDefaultTyping(LaissezFaireSubTypeValidator.instance, ObjectMapper.DefaultTyping.NON_FINAL, JsonTypeInfo.As.WRAPPER_ARRAY);
            jacksonSeial.setObjectMapper(om);
            StringRedisSerializer stringSerial = new StringRedisSerializer();
            // redis key 序列化方式使用stringSerial
            template.setKeySerializer(stringSerial);
            // redis value 序列化方式使用jackson
            template.setValueSerializer(jacksonSeial);
            // redis hash key 序列化方式使用stringSerial
            template.setHashKeySerializer(stringSerial);
            // redis hash value 序列化方式使用jackson
            template.setHashValueSerializer(jacksonSeial);
            template.afterPropertiesSet();
            return template;
        }
