RedisCacheManager:JSON序列化、Cannot resolve constructor ‘RedisCacheManager‘

Error:
Cannot resolve constructor'RedisCacheManager(orgspringframeworkdata.reds.core.RedisTemplatesjava.lang.Object,com.demo.webdemo.pojo.User>"

Springboot2.x has changed RedisCacheManager, and the single parameter of RedisCacheManager is no longer applicable.

Therefore, if you want to serialize json objects, please see the following code

@Bean
   public CacheManager redisCacheManager(RedisConnectionFactory factory){
    
    


      Jackson2JsonRedisSerializer<User> user = new Jackson2JsonRedisSerializer<>(User.class);

      RedisCacheConfiguration cacheManager =
              RedisCacheConfiguration.defaultCacheConfig()
                      //设置缓存有效时间(1小时)
                      .entryTtl(Duration.ofHours(1))
                      //不缓存null结果，若出现null结果时会报异常
                      .disableCachingNullValues()
                      //以json形式序列化对象
                      .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(user));


      return RedisCacheManager.builder(factory).cacheDefaults(cacheManager).build();
   }
