在spring boot中多次控制redis过期时间

首先建立配置类，实例化2个CacheManager的bean，且实现json序列化，其中一个设为primary，,然后，在实际的service层注解中，用cachemanage引用这个两个不同的bean，，

 

@Configuration
public class RedisManager {
    
     @Bean
     @Primary
     public RedisCacheManager cacheManager(RedisConnectionFactory redisConnectionFactory) {
     //初始化一个RedisCacheWriter
     RedisCacheWriter redisCacheWriter = RedisCacheWriter.nonLockingRedisCacheWriter(redisConnectionFactory);
     //设置CacheManager的值序列化方式为json序列化
     RedisSerializer<Object> jsonSerializer = new GenericJackson2JsonRedisSerializer();
     RedisSerializationContext.SerializationPair<Object> pair = RedisSerializationContext.SerializationPair.fromSerializer(jsonSerializer);
     RedisCacheConfiguration defaultCacheConfig = RedisCacheConfiguration.defaultCacheConfig()
             .serializeValuesWith(pair).entryTtl(Duration.ofHours(3));

     //设置默认超过时期是3小时
     //初始化RedisCacheManager
     return new RedisCacheManager(redisCacheWriter, defaultCacheConfig);
     }
    
    @Bean
    public CacheProperties    cacheProperties() {
        CacheProperties cp = new CacheProperties();
        //cp.getRedis().setTimeToLive(Duration.ofHours(4));
        return cp;
    } 
    
    @Bean(name = "zhouyi")
     public RedisCacheManager cacheManager1(RedisConnectionFactory redisConnectionFactory) {
         //初始化一个RedisCacheWriter
         RedisCacheWriter redisCacheWriter = RedisCacheWriter.nonLockingRedisCacheWriter(redisConnectionFactory);
         //设置CacheManager的值序列化方式为json序列化
         RedisSerializer<Object> jsonSerializer = new GenericJackson2JsonRedisSerializer();
         RedisSerializationContext.SerializationPair<Object> pair = RedisSerializationContext.SerializationPair.fromSerializer(jsonSerializer);
         RedisCacheConfiguration defaultCacheConfig = RedisCacheConfiguration.defaultCacheConfig()
                 .serializeValuesWith(pair).entryTtl(Duration.ZERO);

         //设置默认超过时期为永久
        
         //初始化RedisCacheManager
         return new RedisCacheManager(redisCacheWriter, defaultCacheConfig);
         }
    
}

 

在实际的操作中，通过cacheManager注解引用

@Cacheable(cacheNames = "ZhouyiYao",key = "#rawId+':'+#bianYao",cacheManager = "zhouyi")
    public ZhouyiYao getZhaoyiYaoByZhanbu(Integer rawId, Integer bianYao) {
        return zhouyiYaoMapper.getZhaoyiYaoByZhanbu(rawId, bianYao);
    }

 

实际操作，因为初始化时，yml中需要提升连接超时时间

spring:
  redis:
    host: 127.0.0.1
    port: 6379
    connect-timeout: 15000
