Spring Boot 整合——Redis实现简单的发布订阅以及配置序列化方式

设置序列化方式

为key和value配置特殊的序列化工具

下面的内容，使得key使用了StringRedisSerializer序列化工具。
使用value 使用了jackson2JsonRedisSerializer的序列化工具

@Configuration
public class RedisConfig extends CachingConfigurerSupport {
   
   

    @Bean
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
   
   
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        // json序列化
        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.setConnectionFactory(factory);
        // key序列化方式
        template.setKeySerializer(new StringRedisSerializer());
        // value序列化
        template.setValueSerializer(jackson2JsonRedisSerializer);
        // value hasHmap序列化
        template.setHashValueSerializer(jackson2JsonRedisSerializer);

        return template;
    }

    @Bean
    public CacheManager cacheManager(RedisConnectionFactory factory) {
   
   
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = 
                new Jackson2JsonRedisSerializer(Object.class);
        // 解决查询缓存转换异常的问题
        ObjectMapper om = new ObjectMapper
