spring boot 整合 redis 及 序列化配置

依赖

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

业务使用类

@Service
@Slf4j
public class RedisCsServiceImpl extends ServiceImpl<RedisCsMapper, RedisCs> implements RedisCsService {
 
    @Autowired
    private RedisCsMapper redisCsMapper;
    @Autowired
    private RedisUtils redisUtils;
    @Autowired
    private RedisTemplate redisTemplate;
 
    @Override
    public Object findById(Integer id) {
        //创建key的展示形式
        String key = "user:" + id;
        //先查询Redis缓存
        Object userObj = redisTemplate.opsForValue().get(key);
        if (userObj == null) {
            //多线程同步数据
            synchronized (this.getClass()) {
                //再查一次缓存,防止查询数据有延迟
                userObj = redisTemplate.opsForValue().get(key);
                if (userObj==null){
                    log.debug("====查询数据库====");
                    //缓存没有数据,查询MySQL数据库里面的数据
                    RedisCs redisCs = baseMapper.selectById(id);
                    //帮MySQL查询出来的数据返回的同时,把数据写入到Redis进行缓存
                    redisTemplate.opsForValue().set(key,redisCs);
                    return redisCs;
                }else {
                    log.debug("====查询缓存(同步代码块)====");
                    return userObj;
                }
            }
        }else {
            log.debug("====查询缓存====");
        }
       return userObj;
    }
 
}

配置类1

/**
 * 设定redis返回的展示格式
 */
@Configuration
public class RedisConfig {
    @Bean
    public RedisTemplate<String,Object> redisTemplate(RedisConnectionFactory factory){
        RedisTemplate<String,Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(factory);
 
        //指定key,value的序列化方式
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        return redisTemplate;
    }
}

@Configuration
public class RedisConfiguration {
 
    @Bean
    @SuppressWarnings("all")
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
        RedisTemplate<String, Object> template = new RedisTemplate<String, Object>();
        template.setConnectionFactory(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);
 
        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
        template.setKeySerializer(stringRedisSerializer);
        template.setHashKeySerializer(stringRedisSerializer);
        template.setValueSerializer(jackson2JsonRedisSerializer);
        template.setHashValueSerializer(jackson2JsonRedisSerializer);
        template.afterPropertiesSet();
        return template;
    }
