Spring boot redis 实现缓存

配置 redis

@Configuration
@EnableCaching
public class RedisConfig extends CachingConfigurerSupport {
@Value("${spring.redis.host}")
private String host;
@Value("${spring.redis.port}")
private int port;
@Value("${spring.redis.timeout}")
private int timeout;

//缓存管理器
@Bean
public CacheManager cacheManager(@SuppressWarnings("rawtypes") RedisTemplate redisTemplate) {
RedisCacheManager cacheManager = new RedisCacheManager(redisTemplate);
//设置缓存过期时间
cacheManager.setDefaultExpiration(30000);
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){
@SuppressWarnings({ "rawtypes", "unchecked" })
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);
}

在DAO上加上缓存标准
