springboot-redis使用fastjson2

1、pom

注：springboot2.*使用fastjson2-extension-spring5，3.*使用fastjson2-extension-spring6

<fastjson.version>2.0.37</fastjson.version>
<!-- json -->
<dependency>
    <groupId>com.alibaba.fastjson2</groupId>
    <artifactId>fastjson2</artifactId>
    <version>${fastjson.version}</version>
</dependency>
<dependency>
    <groupId>com.alibaba.fastjson2</groupId>
    <artifactId>fastjson2-extension</artifactId>
    <version>${fastjson.version}</version>
</dependency>
<dependency>
    <groupId>com.alibaba.fastjson2</groupId>
    <artifactId>fastjson2-extension-spring5</artifactId>
    <version>${fastjson.version}</version>
</dependency>

2、RedisConfig

import com.alibaba.fastjson2.support.spring.data.redis.FastJsonRedisSerializer;
import lombok.extern.log4j.Log4j2;
import org.springframework.beans.factory.annotation.Autowired;
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;


@Log4j2
@Configuration
public class RedisConfig {
    @Autowired
    private RedisConnectionFactory factory;

    @Bean(name = "redisTemplate")
    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<Object, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(redisConnectionFactory);
        //序列化
        //如需使用类自动化装配（redis直接存储类对象），请使用类FastJson2RedisSerializer序列化
        FastJsonRedisSerializer<Object> fastJsonRedisSerializer = new FastJsonRedisSerializer<>(Object.class);
        // value值的序列化采用fastJsonRedisSerializer
        template.setDefaultSerializer(fastJsonRedisSerializer);
        log.info("redis client初始化完成");
        return template;
    }
}

3、FastJson2RedisSerializer

import com.alibaba.fastjson2.JSON;
import com.alibaba.fastjson2.JSONReader;
import com.alibaba.fastjson2.JSONWriter;
import com.alibaba.fastjson2.filter.Filter;
import org.springframework.data.redis.serializer.RedisSerializer;

public class FastJson2RedisSerializer<T> implements RedisSerializer<T> {
    static final Filter autoTypeFilter = JSONReader.autoTypeFilter(
            // 按需加上需要支持自动类型的类名前缀，范围越小越安全
            "com.***.***.***","com.***.***.***"
    );

    private Class<T> clazz;

    public FastJson2RedisSerializer(Class<T> clazz) {
        super();
        this.clazz = clazz;
    }

    @Override
    public byte[] serialize(T t) {
        if (t == null) {
            return new byte[0];
        }
        return JSON.toJSONBytes(t, JSONWriter.Feature.WriteClassName);
    }

    @Override
    public T deserialize(byte[] bytes) {
        if (bytes == null || bytes.length <= 0) {
            return null;
        }

        return JSON.parseObject(bytes, clazz, autoTypeFilter);
    }
}
