JSON序列化与JDK序列化在存储和效率上的对比：为什么会出现不同的结果？

@SpringBootTest
public class RedisSerializerTest {
    @Autowired
    RedisTemplate redisTemplate;
    @Autowired
    ObjectMapper objectMapper;

    @BeforeEach
    void initRedisTemplate() {
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(genericJackson2JsonRedisSerializer());
        redisTemplate.setHashKeySerializer(genericJackson2JsonRedisSerializer());
        redisTemplate.setHashValueSerializer(genericJackson2JsonRedisSerializer());
    }

    @BeforeEach
    void initObjectMapper() {
        objectMapper = new ObjectMapper();
        objectMapper.registerModule(new JavaTimeModule());
    }

    @Test
    void testRedis() throws JsonProcessingException {
        ComplexObject complexObject = createComplexObject();
        redisTemplate.opsForValue().set("testSerailizerByJson:1", complexObject);
        redisTemplate.setValueSerializer(RedisSerializer.java()); //此处需确认RedisSerializer.java的实现
        redisTemplate.opsForValue().set("testSeralizerByJdk:1", complexObject);
    }

    ComplexObject createComplexObject() {
        ComplexObject complexObject = new ComplexObject();
        complexObject.setName("Test Name");
        complexObject.setAge(30);
        complexObject.setHobbies(Arrays.asList("Hobby1", "Hobby2", "Hobby3"));
        Map<String, String> attributes = new HashMap<>(); //修正类型错误
        for (int i = 0; i < 10; i++) {
            attributes.put("attribute" + i, "value" + i);
        }
        complexObject.setAttributes(attributes);
        return complexObject;
    }
    // ... (ComplexObject类定义) ...
}
