一直都是用别人整合好的项目，所以今天自己整合一下，分享给大家。
首先，下载Redis，如何下载安装可以看菜鸟教程(https://www.runoob.com/redis/redis-install.html)。
RedisDesktopManager不是很好看，我在GitHub上发现了一个超级好看的可视化软件，给大家看一下

是不是很好看呀，软件下载地址和项目下载地址都在文章末尾，好了，我们开始吧
第一，先搭建一个常规的SpringBoot项目，搭建成功之后引入redis的依赖
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-redis</artifactId> </dependency>第二，我们来配置Redis
# Redis 数据库索引（默认为 0） spring.redis.database=0 # Redis 服务器地址 spring.redis.host=127.0.0.1 # Redis 服务器连接端口 spring.redis.port=6379 # Redis 服务器连接密码（默认为空） spring.redis.password= # 连接池最大连接数（使用负值表示没有限制） spring.redis.lettuce.pool.max-active=50 # 连接池最大阻塞等待时间（使用负值表示没有限制） spring.redis.lettuce.pool.max-wait=-1s # 连接池中的最大空闲连接 spring.redis.lettuce.pool.max-idle=20 # 连接池中的最小空闲连接 spring.redis.lettuce.pool.min-idle=10 spring.redis.lettuce.shutdown-timeout=5s`第三，我们来配置RedisTemplate
@Configuration @EnableCaching public class RedisConfig { @Bean public RedisTemplate<String, Object> redisTemplate(LettuceConnectionFactory lettuceConnectionFactory) { //设置序列化 Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class); ObjectMapper om = new ObjectMapper(); om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY); om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL); jackson2JsonRedisSerializer.setObjectMapper(om); //配置redisTemplate RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>(); redisTemplate.setConnectionFactory(lettuceConnectionFactory); RedisSerializer stringSerializer = new StringRedisSerializer(); //key序列化 redisTemplate.setKeySerializer(stringSerializer); //value序列化 redisTemplate.setValueSerializer(jackson2JsonRedisSerializer); //Hash key序列化 redisTemplate.setHashKeySerializer(stringSerializer); //Hash value序列化 redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer); redisTemplate.afterPropertiesSet(); return redisTemplate; } }第四，我们来写一个Redis的工具类
@Component public class RedisUtil { @Resource private RedisTemplate redisTemplate; /** * 批量删除对应的value * * @param keys */ public void remove(final String... keys) { for (String key : keys) { remove(key); } } /** * 批量删除key * * @param pattern */ public void removePattern(final String pattern) { Set<Serializable> keys = redisTemplate.keys(pattern); if (keys.size() > 0) redisTemplate.delete(keys); } /** * 删除对应的value * * @param key */ public void remove(final String key) { if (exists(key)) { redisTemplate.delete(key); } } /** * 判断缓存中是否有对应的value * * @param key * @return */ public boolean exists(final String key) { return redisTemplate.hasKey(key); } /** * 读取缓存 * * @param key * @return */ public <T> T get(final String key, Class<T> clazz) { ValueOperations<Serializable, Object> operations = redisTemplate.opsForValue(); Object obj = operations.get(key); if (key != null && obj != null) { if (clazz == int.class || clazz == Integer.class) { return (T) Integer.valueOf((String) obj); } else if (clazz == String.class) { return (T) obj; } else if (clazz == long.class || clazz == Long.class) { return (T) Long.valueOf((String) obj); } else { return JSON.parseObject((String) obj, clazz); } } return null; } /** * 写入缓存 * * @param key * @param value * @return */ public <T> boolean set(final String key, T value) { boolean result = false; try { ValueOperations<Serializable, Object> operations = redisTemplate.opsForValue(); operations.set(key, beanToString(value)); result = true; } catch (Exception e) { e.printStackTrace(); } return result; } /** * 写入缓存,带过期时间 * * @param key * @param value * @return */ public <T> boolean set(final String key, T value, Long expireTime) { boolean result = false; try { ValueOperations<Serializable, Object> operations = redisTemplate.opsForValue(); operations.set(key, beanToString(value)); redisTemplate.expire(key, expireTime, TimeUnit.SECONDS); result = true; } catch (Exception e) { e.printStackTrace(); } return result; } public <T> String beanToString(T value) { if (value == null) { return null; } Class<?> clazz = value.getClass(); if (clazz == int.class || clazz == Integer.class) { return "" + value; } else if (clazz == String.class) { return (String) value; } else if (clazz == long.class || clazz == Long.class) { return "" + value; } else { return JSON.toJSONString(value); } } /** * List集合写入缓存 */ public boolean setList(final String key, Object object) { boolean result = false; try { redisTemplate.opsForList().rightPush(key, object); result = true; } catch (Exception e) { e.printStackTrace(); } return result; } /** * List集合写入缓存,带过期时间 */ public boolean setList(final String key, Object object, Long expireTime) { boolean result = false; try { redisTemplate.opsForList().rightPush(key, object); redisTemplate.expire(key, expireTime, TimeUnit.SECONDS); result = true; } catch (Exception e) { e.printStackTrace(); } return result; } /** * List集合整个写入缓存 */ public boolean setListAll(final String key, List list) { boolean result = false; try { redisTemplate.opsForList().rightPushAll(key, list); result = true; } catch (Exception e) { e.printStackTrace(); } return result; } /** * List集合整个写入缓存,带过期时间 */ public boolean setListAll(final String key, List list, Long expireTime) { boolean result = false; try { redisTemplate.opsForList().rightPushAll(key, list); redisTemplate.expire(key, expireTime, TimeUnit.SECONDS); result = true; } catch (Exception e) { e.printStackTrace(); } return result; } /** * 获取List集合 */ public List getList(final String key, long start, long end) { List result = null; result = redisTemplate.opsForList().range(key, start, end); return result; } /** * Set集合写入缓存 */ public boolean setSet(final String key, Set set) { boolean result = false; try { SetOperations<String, Object> setOperations = redisTemplate.opsForSet(); for (Object o : set) { setOperations.add(key, o); } result = true; } catch (Exception e) { e.printStackTrace(); } return result; } public boolean setSet(final String key, Object object) { boolean result = false; try { SetOperations<String, Object> setOperations = redisTemplate.opsForSet(); setOperations.add(key, object); result = true; } catch (Exception e) { e.printStackTrace(); } return result; } /** * Set集合写入缓存,带过期时间 */ public boolean setSet(final String key, Object object, Long expireTime) { boolean result = false; try { SetOperations<String, Object> setOperations = redisTemplate.opsForSet(); setOperations.add(key, object); redisTemplate.expire(key, expireTime, TimeUnit.SECONDS); result = true; } catch (Exception e) { e.printStackTrace(); } return result; } public boolean setSet(final String key, Set set, Long expireTime) { boolean result = false; try { SetOperations<String, Object> setOperations = redisTemplate.opsForSet(); for (Object o : set) { setOperations.add(key, o); } redisTemplate.expire(key, expireTime, TimeUnit.SECONDS); result = true; } catch (Exception e) { e.printStackTrace(); } return result; } /** * 获取Set集合 */ public Set getSet(final String key) { Set result = null; result = redisTemplate.opsForSet().members(key); return result; } /** * Map集合写入缓存 */ public boolean setMap(final String key, Map map) { boolean result = false; try { redisTemplate.opsForHash().putAll(key, map); result = true; } catch (Exception e) { e.printStackTrace(); } return result; } /** * Map集合写入缓存,带过期时间 */ public boolean setMap(final String key, Map map, Long expireTime) { boolean result = false; try { redisTemplate.opsForHash().putAll(key, map); redisTemplate.expire(key, expireTime, TimeUnit.SECONDS); result = true; } catch (Exception e) { e.printStackTrace(); } return result; } /** * 取出Map集合 */ public Map getMap(final String key) { Map result = null; result = redisTemplate.opsForHash().entries(key); return result; } /** * 获取自增ID */ public Long incr(String key) { RedisAtomicLong redisAtomicLong = new RedisAtomicLong(key, redisTemplate.getConnectionFactory()); Long increment = redisAtomicLong.getAndIncrement(); // if ((null == increment || increment.longValue() == 0) && liveTime > 0) {//初始设置过期时间 // redisAtomicLong.expire(liveTime, TimeUnit.SECONDS); // } return increment; } }第五，在逻辑中使用Redis
List<User> userList = userMapper.getAllUser(); //写入缓存 for(User user:userList){ redisUtil.set("user_" + user.getName(),user); }
