spring boot整合redis

第一步：創建一個springboot項目

第二步：引入redis依賴

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

第三步：啓動類開啓緩存註解

@EnableDiscoveryClient
@SpringBootApplication
@EnableFeignClients
@EnableCaching //開啓緩存
public class SpringBootRedisApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringBootRedisApplication.class, args);
    }
}

第四步：添加redis配置類

@Configuration
public class RedisConfig extends CachingConfigurerSupport {

	@Bean
	public CacheManager cacheManager(@Qualifier("redisTemplate") RedisTemplate template) {
		return new RedisCacheManager(template);
	}

	@Bean("redisTemplate")
	public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
		Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<>(
				Object.class);
		ObjectMapper objectMapper = new ObjectMapper();
		objectMapper.setVisibility(PropertyAccessor.ALL, Visibility.ANY);
		objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
		jackson2JsonRedisSerializer.setObjectMapper(objectMapper);

		RedisTemplate<String, Object> template = new RedisTemplate<>();
		StringRedisSerializer stringRedisSerializer = new StringRedisSerializer(Charset.forName("UTF-8"));
		template.setConnectionFactory(redisConnectionFactory);
		template.setKeySerializer(stringRedisSerializer);
		template.setValueSerializer(jackson2JsonRedisSerializer);
		template.setHashKeySerializer(stringRedisSerializer);
		template.setHashValueSerializer(jackson2JsonRedisSerializer);
		return template;
	}
}

第五步：編寫測試方法，在方法上添加註解使用緩存

/** 
 * @Title: cachePut 
 * @Description: cachePut測試
 * @return
 * @return: Object
 */
@CachePut(value = "test", key = "'test:put'")
public Object cachePut() {
	System.out.println("未走緩存");
	return "cachePut";
}

/** 
 * @Title: cacheable 
 * @Description: cacheable測試
 * @return
 * @return: Object
 */
@Cacheable(value = "test", key = "'test:able'")
public Object cacheable() {
	System.out.println("未走緩存");
	return "Cacheable";
}
