spring boot redis配置

导入依赖

redis yml

spring:  redis:    database: 0    host: 10.0.0.163    port: 6379    timeout: 3000    pool:      # 连接池最大连接数（使用负值表示没有限制）      max-active: 8      # 连接池最大阻塞等待时间（使用负值表示没有限制）      max-wait: -1      # 连接池中的最大空闲连接      max-idle: 8      # 连接池中的最小空闲连接      min-idle: 0

@Configuration@EnableCachingpublic class RedisConfig extends CachingConfigurerSupport {    @Value("${redis-timeout}")    private Long redisTimeout;    //缓存管理器    @Bean    public CacheManager cacheManager(RedisTemplate redisTemplate) {        RedisCacheManager cacheManager = new RedisCacheManager(redisTemplate);        //设置缓存过期时间        cacheManager.setDefaultExpiration(redisTimeout);        return cacheManager;    }    @Bean    public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory factory){        StringRedisTemplate template = new StringRedisTemplate(factory);        setSerializer(template);//设置序列化工具        template.afterPropertiesSet();        return template;    }    private void setSerializer(StringRedisTemplate template){        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);    }}

为了方便使用将redis写成工具包

@Componentpublic class RedisUtil {    @Autowired    private RedisTemplate redisTemplate;    /**     * @Description: 批量删除缓存     * @Author: hj     * @Date: 17:13 2017/10/24     */    public void remove(final String... keys) {        for (String key : keys) {            remove(key);        }    }    /**     * @Description: 批量删除缓存(通配符)     * @Author: hj     * @Date: 16:52 2017/10/24     */    public void removePattern(final String pattern) {        Set<Serializable> keys = redisTemplate.keys(pattern);        if (keys.size() > 0)            redisTemplate.delete(keys);    }    /**     * @Description: 删除缓存     * @Author: hj     * @Date: 16:51 2017/10/24     */    public void remove(final String key) {        if (exists(key)) {            redisTemplate.delete(key);        }    }    /**     * @Description: 判断缓存中是否有对应的value     * @Author: hj     * @Date: 16:50 2017/10/24     */    public boolean exists(final String key) {        return redisTemplate.hasKey(key);    }    /**     * @Description: 读取缓存     * @Author: hj     * @Date: 16:49 2017/10/24     */    public Object get(final String key) {        return redisTemplate.opsForValue().get(key);    }    /**     * @Description: 写入缓存     * @Author: hj     * @Date: 16:48 2017/10/24     */    public boolean set(final String key, Object value) {        boolean result = false;        try {            redisTemplate.opsForValue().set(key, value);            result = true;        } catch (Exception e) {            e.printStackTrace();        }        return result;    }    /**     * @Description: 写入缓存(可以配置过期时间)     * @Author: hj     * @Date: 16:46 2017/10/24     */    public boolean set(final String key, Object value, Long expireTime) {        boolean result = false;        try {            redisTemplate.opsForValue().set(key, value);            redisTemplate.expire(key, expireTime, TimeUnit.SECONDS);            result = true;        } catch (Exception e) {            e.printStackTrace();        }        return result;    }}

Controller就不写了,测试Service

@Servicepublic class TestService {    @Autowired    private TestMapper testMapper;    @Autowired    private RedisUtil redisUtil;    public Test test1(Test test) {        Test mytest = testMapper.getOneById(test.getId());        redisUtil.set("test",mytest,10L);  //10秒过期        return mytest;    }    public Test test2() {        return (Test)redisUtil.get("test");    }}
