springboot 2.2.X 自定义CacheManager，JSON序列化配置

springboot2.x后对于CacheManager的源码进行了改动，1.x版本自定义CacheManager方法不再适用，以下是本人配置的CacheManager

@Configuration
public class MyRedisConfig {
    @Bean
    public RedisTemplate<Object, Employee> empRedisTemplate(RedisConnectionFactory redisConnectionFactory)
            throws UnknownHostException {
        RedisTemplate<Object, Employee> template = new RedisTemplate<>();
        template.setConnectionFactory(redisConnectionFactory);
        Jackson2JsonRedisSerializer<Employee> serializer = new Jackson2JsonRedisSerializer<Employee>(Employee.class);
        template.setDefaultSerializer(serializer);
        return template;
    }

    @Bean
    public RedisTemplate<Object, Department> deptRedisTemplate(RedisConnectionFactory redisConnectionFactory)
            throws UnknownHostException {
        RedisTemplate<Object, Department> template = new RedisTemplate<>();
        template.setConnectionFactory(redisConnectionFactory);
        Jackson2JsonRedisSerializer<Department> serializer = new Jackson2JsonRedisSerializer<Department>(Department.class);
        template.setDefaultSerializer(serializer);
        return template;
    }

    @Bean
    @Primary  //将某个缓存管理器作为默认的,
    public CacheManager empCacheManager(RedisConnectionFactory factory) {
        Jackson2JsonRedisSerializer<Employee> serializer = new Jackson2JsonRedisSerializer<Employee>(Employee.class);
        RedisCacheConfiguration cacheConfiguration =
                RedisCacheConfiguration.defaultCacheConfig()
                        .entryTtl(Duration.ofDays(1))
                        .disableCachingNullValues()
                        .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(serializer));
        return RedisCacheManager.builder(factory).cacheDefaults(cacheConfiguration).build();
    }


    @Bean
    public CacheManager deptCacheManager(RedisConnectionFactory factory) {
        Jackson2JsonRedisSerializer<Department> serializer = new Jackson2JsonRedisSerializer<Department>(Department.class);
        RedisCacheConfiguration cacheConfiguration =
                RedisCacheConfiguration.defaultCacheConfig()
                        .entryTtl(Duration.ofDays(1))
                        .disableCachingNullValues()
                        .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(serializer));
        return RedisCacheManager.builder(factory).cacheDefaults(cacheConfiguration).build();
    }



}

 

 前面两个bean是对RedisTemplate重新定义了序列化规则，后面两个bean针对

defaultCacheConfig，做出自定义的设置，

[SpringBoot版本 2.3.0      JDK 1.8    IDEA环境     redis采用dockerHub最新镜像启动]

亲测有效！！！
