该代码示例展示了如何利用Fastjson库进行对象的序列化和反序列化，并结合RedisClient与Redis进行数据的存取操作。主要方法包括获取Redis客户端、从Redis中获取和设置键值对，以及执行Redis命令。

通过fastjson对对象进行序列化和反序列化

public class RedisUtil {


    private static final String host = "localhost";

    private static final int port = 6379;

    public static final RedisClient redisClient = RedisClient.create(RedisURI.builder().withHost(host).withPort(port)
            .build());

    public static RedisClient getRedisClient() {
        return redisClient;
    }

    public static <T> T get(String key, Class<T> clazz) {
        return JSONObject.parseObject(get(key), clazz);
    }

    public static String get(String key) {
        return execute(o -> o.get(key));
    }

    public static <T> String set(String key, T value) {
        return set(key, JSON.toJSONString(value));
    }

    public static <T> String set(String key, String value) {
        return execute(o -> o.set(key, value));
    }

    public static <T> T execute(Function<RedisCommands<String, String>, T> function) {
        return execute(getRedisClient(), function);
    }

    public static <T> T execute(RedisClient redisClient, Function<RedisCommands<String, String>, T> function) {
        try (StatefulRedisConnection<String, String> connect = redisClient.connect()) {
            return execute(connect, function);
        }
    }

    public static <T> T execute(StatefulRedisConnection<String, String> connect, Function<RedisCommands<String, String>, T> function) {
        return function.apply(connect.sync());
    }
}
