关于redis:解决Redis序列化Java8的LocalDateTime问题

在从Redis获取带有LocalDateTime类型属性的对象时，产生序列化和反序列化问题解决办法
形式一：实体类上指定LocalDateTime的序列化器和反序列化器

  @JsonDeserialize(using = LocalDateTimeDeserializer.class)  //反序列化  @JsonSerialize(using = LocalDateTimeSerializer.class)  //序列化  private LocalDateTime birthday;

形式二：在Redis的配置类中指明序列化的形式

  @Configuration    public class RedisConfig {    private static final DateTimeFormatter DATE_TIME_FORMATTER = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");    private static final DateTimeFormatter DATE_FORMATTER = DateTimeFormatter.ofPattern("yyyy-MM-dd");    private static final DateTimeFormatter TIME_FORMATTER = DateTimeFormatter.ofPattern("HH:mm:ss");    @Bean    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {        RedisTemplate<String, Object> template = new RedisTemplate<>();        template.setConnectionFactory(redisConnectionFactory);        /**         * JSON序列化         */        Jackson2JsonRedisSerializer serializer = new Jackson2JsonRedisSerializer(Object.class);        ObjectMapper mapper = new ObjectMapper();        //勾销工夫转换格局，默认是工夫戳，同时须要设置要体现的工夫格局        mapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);        mapper.configure(SerializationFeature.WRITE_DURATIONS_AS_TIMESTAMPS, false);        mapper.setDateFormat(new SimpleDateFormat("yyy-MM-dd HH:mm:ss"));        //默认序列化没有实现，反序列化有实现        JavaTimeModule javaTimeModule = new JavaTimeModule();        javaTimeModule.addSerializer(LocalDateTime.class, new LocalDateTimeSerializer(DATE_TIME_FORMATTER));//        javaTimeModule.addSerializer(LocalDateTime.class, new LocalDateTimeSerializer(DATE_FORMATTER));//        javaTimeModule.addSerializer(LocalDateTime.class, new LocalDateTimeSerializer(TIME_FORMATTER));        mapper.registerModule(javaTimeModule);        //设置时区        mapper.setTimeZone(TimeZone.getDefault());        //设置格式化输入//        MAPPER.enable(SerializationFeature.INDENT_OUTPUT);        //设置格式化输入        mapper.setPropertyNamingStrategy(PropertyNamingStrategy.SNAKE_CASE);        mapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);        serializer.setObjectMapper(mapper);//        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();        template.setKeySerializer(serializer);        template.setHashKeySerializer(serializer);        template.setValueSerializer(serializer);        template.setHashValueSerializer(serializer);        return template;    }}
