实现"fastjson GenericFastJsonRedisSerializer"的步骤如下：

  1. 导入依赖 首先，你需要在项目的pom.xml文件中添加fastjson和spring-data-redis的依赖。代码如下：
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>fastjson</artifactId>
    <version>1.2.68</version>
</dependency>

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
  1. 创建序列化器 创建一个自定义的序列化器GenericFastJsonRedisSerializer，实现RedisSerializer接口。代码如下：
import com.alibaba.fastjson.JSON;
import org.springframework.data.redis.serializer.RedisSerializer;
import org.springframework.data.redis.serializer.SerializationException;

public class GenericFastJsonRedisSerializer<T> implements RedisSerializer<T> {

    @Override
    public byte[] serialize(T t) throws SerializationException {
        if (t == null) {
            return new byte[0];
        }
        return JSON.toJSONBytes(t);
    }

    @Override
    public T deserialize(byte[] bytes) throws SerializationException {
        if (bytes == null || bytes.length == 0) {
            return null;
        }
        return JSON.parseObject(bytes, clazz);
    }
}
  1. 配置RedisTemplate 在Spring Boot的配置类中，配置RedisTemplate的序列化器为GenericFastJsonRedisSerializer。代码如下：
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.StringRedisSerializer;

@Configuration
public class RedisConfig {

    @Bean
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(factory);
        template.setKeySerializer(new StringRedisSerializer());
        template.setValueSerializer(new GenericFastJsonRedisSerializer());
        template.setHashKeySerializer(new StringRedisSerializer());
        template.setHashValueSerializer(new GenericFastJsonRedisSerializer());
        return template;
    }
}
  1. 使用RedisTemplate 在需要使用Redis的地方，使用@Autowired注入RedisTemplate，并使用它进行数据的存储和读取操作。代码如下：
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Service;

@Service
public class UserService {

    @Autowired
    private RedisTemplate<String, Object> redisTemplate;

    public void saveUser(User user) {
        redisTemplate.opsForValue().set("user:" + user.getId(), user);
    }

    public User getUser(String id) {
        return (User) redisTemplate.opsForValue().get("user:" + id);
    }
}

以上就是实现"fastjson GenericFastJsonRedisSerializer"的整个过程。下面是状态图和序列图的示例：

状态图：

stateDiagram
    [*] --> RedisConfig
    RedisConfig --> [*]

序列图：

sequenceDiagram
    participant Client
    participant RedisConfig
    participant UserService

    Client->>UserService: saveUser(user)
    activate UserService
    UserService->>RedisConfig: redisTemplate.opsForValue().set(key, value)
    activate RedisConfig
    RedisConfig->>Redis: Redis存储操作
    activate Redis
    Redis->>RedisConfig: 存储完成
    deactivate Redis
    RedisConfig->>UserService: 存储完成
    deactivate RedisConfig
    UserService->>Client: 存储完成
    deactivate UserService

    Client->>UserService: getUser(id)
    activate UserService
    UserService->>RedisConfig: redisTemplate.opsForValue().get(key)
    activate RedisConfig
    RedisConfig->>Redis: Redis读取操作
    activate Redis
    Redis->>RedisConfig: 读取完成
    deactivate Redis
    RedisConfig->>UserService: 读取完成
    deactivate RedisConfig
    UserService->>Client: 返回用户信息
    deactivate UserService

通过以上步骤，你现在应该已经了解如何实现"fastjson GenericFastJsonRedisSerializer"了。希望对你有帮助！
