1. 引入依賴

    <parent>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-parent</artifactId>        <version>2.0.3.RELEASE</version>        <relativePath/> <!-- lookup parent from repository -->    </parent>    <properties>        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>        <java.version>1.8</java.version>        <spring.data.redis.version>2.0.8.RELEASE</spring.data.redis.version><!--1.8.7.RELEASE-->    </properties>    <dependencies>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-web</artifactId>        </dependency>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-data-redis</artifactId>        </dependency>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-test</artifactId>            <scope>test</scope>        </dependency>        <dependency>            <groupId>org.springframework.data</groupId>            <artifactId>spring-data-redis</artifactId>            <version>${spring.data.redis.version}</version>        </dependency>        <dependency>            <groupId>redis.clients</groupId>            <artifactId>jedis</artifactId>            <version>2.9.0</version>        </dependency>    </dependencies>

2. application.yml中添加配置

spring:    redis:      #資料庫索引      database: 0      host: 127.0.0.1      port: 6379      password:      jedis:        pool:          #最大串連數          max-active: 8          #最大阻塞等待時間(負數表示沒限制)          max-wait: -1          #最大空閑          max-idle: 8          #最小空閑          min-idle: 0      #連線逾時時間      timeout: 10000

3. RedisConfiguration

@Configuration@EnableCachingpublic class RedisConfiguration extends CachingConfigurerSupport {    @Bean    public KeyGenerator keyGenerator() {        return new KeyGenerator() {            @Override            public Object generate(Object target, Method method, Object... params) {                StringBuilder sb = new StringBuilder();                sb.append(target.getClass().getName());                sb.append(method.getName());                for (Object obj : params) {                    sb.append(obj.toString());                }                return sb.toString();            }        };    }//    @Bean//    public CacheManager cacheManager(RedisTemplate redisTemplate) {//        RedisCacheManager redisCacheManager = new RedisCacheManager(redisTemplate);//        return redisCacheManager;//    }//////    @Bean//    public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory factory) {//        ////解決鍵、值序列化問題//        StringRedisTemplate template = new StringRedisTemplate(factory);//        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);//        template.setValueSerializer(jackson2JsonRedisSerializer);//        template.afterPropertiesSet();//        return template;//    }    /*    spring-data-redis  版本不同，方法也不一樣    上面是1.5    下面是2.0    */    @Bean    public CacheManager cacheManager(RedisConnectionFactory connectionFactory) {        RedisCacheManager redisCacheManager = RedisCacheManager.builder(connectionFactory).build();        return redisCacheManager;    }    /**     * @Description: 防止redis入庫序列化亂碼的問題     * @return     傳回型別     * @date 2018/4/12 10:54     */    @Bean    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory){        RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<Object, Object>();        redisTemplate.setConnectionFactory(redisConnectionFactory);        redisTemplate.setKeySerializer(new StringRedisSerializer());//key序列化        redisTemplate.setValueSerializer(new Jackson2JsonRedisSerializer(Object.class));  //value序列化        redisTemplate.setHashKeySerializer(new StringRedisSerializer());        redisTemplate.setHashValueSerializer(new JdkSerializationRedisSerializer());        redisTemplate.afterPropertiesSet();        return redisTemplate;    }

4. RedisService

@Componentpublic class RedisService<HK, V> {    // 在構造器中擷取redisTemplate執行個體, key(not hashKey) 預設使用String類型    private RedisTemplate<String, V> redisTemplate;    // 在構造器中通過redisTemplate的Factory 方法執行個體化操作對象    private HashOperations<String, HK, V> hashOperations;    private ListOperations<String, V> listOperations;    private ZSetOperations<String, V> zSetOperations;    private SetOperations<String, V> setOperations;    private ValueOperations<String, V> valueOperations;    // IDEA雖然報錯,但是依然可以注入成功, 執行個體化操作對象後就可以直接調用方法操作Redis資料庫    @Autowired    public RedisService(RedisTemplate<String, V> redisTemplate) {        this.redisTemplate = redisTemplate;        this.hashOperations = redisTemplate.opsForHash();        this.listOperations = redisTemplate.opsForList();        this.zSetOperations = redisTemplate.opsForZSet();        this.setOperations = redisTemplate.opsForSet();        this.valueOperations = redisTemplate.opsForValue();    }    public void hashPut(String key, HK hashKey, V value) {        hashOperations.put(key, hashKey, value);    }    public Map<HK, V> hashFindAll(String key) {        return hashOperations.entries(key);    }    public V hashGet(String key, HK hashKey) {        return hashOperations.get(key, hashKey);    }    public void hashRemove(String key, HK hashKey) {        hashOperations.delete(key, hashKey);    }    public Long listPush(String key, V value) {        return listOperations.rightPush(key, value);    }    public Long listUnshift(String key, V value) {        return listOperations.leftPush(key, value);    }    public List<V> listFindAll(String key) {        if (!redisTemplate.hasKey(key)) {            return null;        }        return listOperations.range(key, 0, listOperations.size(key));    }    public V listLPop(String key) {        return listOperations.leftPop(key);    }    public void setValue(String key, V value) {        valueOperations.set(key, value);    }    public void setValue(String key, V value, long timeout) {        ValueOperations<String, V> vo = redisTemplate.opsForValue();        vo.set(key, value, timeout, TimeUnit.MILLISECONDS);    }    public V getValue(String key) {        return valueOperations.get(key);    }    public void remove(String key) {        redisTemplate.delete(key);    }    public boolean expire(String key, long timeout, TimeUnit timeUnit) {        return redisTemplate.expire(key, timeout, timeUnit);    }

5. test

@RunWith(SpringRunner.class)@SpringBootTestpublic class RedisTest {    @Autowired    RedisService redisService;    @Test    public void findAllUsers()  {        redisService.setValue("key","hello");    }    @Test    public void findAllUsers2()  {        System.out.println("get key value:"+ redisService.getValue("key"));    } }

說明

1. 以上是具體的配置，如果沒有引入redis.clients.jedis 依賴，則會報No beans of ‘RedisConnectionFactory‘ type found.
   版本則2.9.0 如果 版本低，則會報其它錯誤
2. spring-data-redis 這個版本分為 1.x 和 2.x 版本變動挺多，不同版本方法也不一樣
