1.需要引入spring-boot-starter-data-redis（Springboot1.5以上引用方式）  而不是   spring-boot-starter-redis（Springboot1.5以下引用方式）

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

2.比較重要的包

cache:將redis用作快取

connection:各種連線方式及連線配置

serializer:系列化器，說白了就是存入redis資料庫的格式宣告，典型儲存方式是Jackson2JsonRedisSerializer

@Bean
	public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory)
			throws UnknownHostException {
		RedisTemplate<Object, Object> template = new RedisTemplate<Object, Object>();
		template.setConnectionFactory(redisConnectionFactory);

		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);

		template.setValueSerializer(jackson2JsonRedisSerializer); // 1
		template.setKeySerializer(new StringRedisSerializer()); // 2

		template.afterPropertiesSet();
		return template;
	}
 

3.redis相關配置

spring.redis.host=localhost
spring.redis.port=6379
#spring.redis.password=
spring.redis.database=1
spring.redis.pool.max-active=8
spring.redis.pool.max-wait=-1
spring.redis.pool.max-idle=500
spring.redis.pool.min-idle=0
spring.redis.timeout=5000

這些配置在字面上很好理解
