上篇介绍了 Spring-boot手动集成redis的方法,本文介绍一下springboot一局系统自动配置

• 导入maven依赖

             
                 
      
       org.springframework.boot
                  
      
       spring-boot-starter-redis
              
     

• 配置springboot的redis环境  application.yml 文件中

 

spring:  redis:    host: 106.14.72.179    password: redispassword    port: 6379    pool:      max-idle: 100      min-idle: 1      max-active: 1000      max-wait: -1

书写配置文件

@Configuration@EnableCachingpublic class RedisConfig extends CachingConfigurerSupport {    /**     * 生成key的策略     * @return     */    @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();            }        };    }    /**     * 管理缓存     */    @Bean    public CacheManager cacheManager(RedisTemplate redisTemplate) {        RedisCacheManager rcm = new RedisCacheManager(redisTemplate);        return rcm;    }    /**     * RedisTemplate配置     */    @Bean    public RedisTemplate
     
       redisTemplate(RedisConnectionFactory factory) {        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;    }}
     

• 编写redis的service类

@Servicepublic class RedisService {    @Autowired    private RedisTemplate redisTemplate;    /**     * 写入缓存     * @param key     * @param value     * @return     */    public boolean set(final String key, Object value) {        boolean result = false;        try {            ValueOperations
     
       operations = redisTemplate.opsForValue();            operations.set(key, value);            result = true;        } catch (Exception e) {            e.printStackTrace();        }        return result;    }    /**     * 写入缓存设置时效时间     * @param key     * @param value     * @return     */    public boolean set(final String key, Object value, Long expireTime) {        boolean result = false;        try {            ValueOperations
      
        operations = redisTemplate.opsForValue();            operations.set(key, value);            redisTemplate.expire(key, expireTime, TimeUnit.SECONDS);            result = true;        } catch (Exception e) {            e.printStackTrace();        }        return result;    }    /**     * 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
       
         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 Object get(final String key) {        Object result = null;        ValueOperations
        
          operations = redisTemplate.opsForValue();        result = operations.get(key);        return result;    }    /**     * 哈希 添加     * @param key     * @param hashKey     * @param value     */    public void hmSet(String key, Object hashKey, Object value){        HashOperations
         
            hash = redisTemplate.opsForHash();        hash.put(key,hashKey,value);    }    /**     * 哈希获取数据     * @param key     * @param hashKey     * @return     */    public Object hmGet(String key, Object hashKey){        HashOperations
          
            hash = redisTemplate.opsForHash(); return hash.get(key,hashKey); } /** * 列表添加 * @param k * @param v */ public void lPush(String k,Object v){ ListOperations
           
             list = redisTemplate.opsForList(); list.rightPush(k,v); } /** * 列表获取 * @param k * @param l * @param l1 * @return */ public List
