Redis在springboot中的使用教程

依賴如下：

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

配置文件如下：

 spring:redis: open: true # 是否開啟redis緩存true開啟false關閉database: 0 host: 47.104.208.124 port: 6378 password: lf.1228 # 密碼（默認為空） timeout: 6000 # 連接超時時長（毫秒） pool: max-active: 1000 # 連接池最大連接數（使用負值表示沒有限制） max-wait: -1 # 連接池最大阻塞等待時間（使用負值表示沒有限制） max-idle: 10 # 連接池中的最大空閒連接min-idle: 5 # 連接池中的最小空閒連接

RedisConfig類：

 @Configurationpublic class RedisConfig { @Autowired private RedisConnectionFactory factory; @Bean public RedisTemplate<String, Object> redisTemplate() { RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>(); redisTemplate.setKeySerializer(new StringRedisSerializer()); redisTemplate.setHashKeySerializer(new StringRedisSerializer()); redisTemplate.setHashValueSerializer(new StringRedisSerializer()); redisTemplate.setValueSerializer(new StringRedisSerializer()); redisTemplate.setConnectionFactory(factory); return redisTemplate; } @Bean public HashOperations<String, String, Object> hashOperations(RedisTemplate<String, Object> redisTemplate) { return redisTemplate.opsForHash(); } @Bean public ValueOperations<String, String> valueOperations(RedisTemplate<String, String> redisTemplate) { return redisTemplate.opsForValue(); } @Bean public ListOperations<String, Object> listOperations(RedisTemplate<String, Object> redisTemplate) { return redisTemplate.opsForList(); } @Bean public SetOperations<String, Object> setOperations(RedisTemplate<String, Object> redisTemplate) { return redisTemplate.opsForSet(); } @Bean public ZSetOperations<String, Object> zSetOperations(RedisTemplate<String, Object> redisTemplate) { return redisTemplate.opsForZSet(); }}

RedisUtils如下：

 @Componentpublic class RedisUtils { @Autowired private RedisTemplate<String, Object> redisTemplate; @Autowired private ValueOperations<String, String> valueOperations; @Autowired private HashOperations<String, String, Object> hashOperations; @Autowired private ListOperations<String, Object> listOperations; @Autowired private SetOperations<String, Object> setOperations; @Autowired private ZSetOperations<String, Object> zSetOperations; /** 默認過期時長，單位：秒*/ public final static long DEFAULT_EXPIRE = 60 * 60 * 24; /** 不設置過期時長*/ public final static long NOT_EXPIRE = -1; private final static Gson gson = new Gson(); public void set(String key, Object value, long expire){ valueOperations.set(key, toJson(value)); if(expire != NOT_EXPIRE){ redisTemplate.expire(key, expire, TimeUnit.SECONDS); } } public void set(String key, Object value){ set(key, value, DEFAULT_EXPIRE); } public <T> T get(String key, Class<T> clazz, long expire) { String value = valueOperations.get(key); if(expire != NOT_EXPIRE){ redisTemplate.expire(key, expire, TimeUnit.SECONDS); } return value == null ? null : fromJson(value, clazz); } public <T> T get(String key, Class<T> clazz) { return get(key, clazz, NOT_EXPIRE); } public String get(String key, long expire) { String value = valueOperations.get(key); if(expire != NOT_EXPIRE){ redisTemplate.expire(key, expire, TimeUnit.SECONDS); } return value; } public String get(String key) { return get(key, NOT_EXPIRE); } public void delete(String key) { redisTemplate.delete(key); } /** * Object轉成JSON數據*/ private String toJson(Object object){ if(object instanceof Integer || object instanceof Long || object instanceof Float || object instanceof Double || object instanceof Boolean || object instanceof String){ return String.valueOf(object); } return gson.toJson(object); } /** * JSON數據，轉成Object */ private <T> T fromJson(String json, Class<T> clazz){ return gson.fromJson(json, clazz); }}

springboot如何封裝redis：

RedisTemplate

所在包：org.springframework.data.redis.core

作用：redis模板，redis事務，序列化支持，操作redis方法

JedisConnectionFactory

所在包：org.springframework.data.redis.connection.jedis
作用：redis連接工廠類，創建redis連接池等

RedisAutoConfiguration

所在包：org.springframework.boot.autoconfigure.data.redis
作用：將redis配置文件相關信息注入工廠類

RedisProperties

所在包：org.springframework.boot.autoconfigure.data.redis
作用：redis連接基礎類通過@ConfigurationProperties註解將配置信息注入屬性
