SpringBoot整合Redis

引入依赖

<dependency>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
    
     <!--用来解决序列化问题-->
<dependency>
     <groupId>com.alibaba</groupId>
     <artifactId>fastjson</artifactId>
     <version>1.2.75</version>
 </dependency>

注意事项：引入依赖报错的时候，可能是SpringBoot版本和Redis版本的问题，建议换一下版本

配置文件

spring.redis.database=0
spring.redis.host=localhost
spring.redis.port=6379
spring.redis.password=

注意事项：密码就算没有，密码配置也最好写上

序列化工具

@Data
public class Fast2JsonSerialize<T> implements RedisSerializer<T> {

    private static final Charset DEFAULT_CHARSET=Charset.forName("UTF-8");
    private Class<T> clazz;

    public Fast2JsonSerialize(Class<T> clazz){
        super();
        this.clazz=clazz;
    }

    static{
        ParserConfig.getGlobalInstance().setAutoTypeSupport(true);
    }

    @Override
    public byte[] serialize(T t) throws SerializationException {
        if(t==null){
            return new byte[0];
        }
  return JSON.toJSONString(t,SerializerFeature.WriteClassName).getBytes(DEFAULT_CHARSET);
    }

    @Override
    public T deserialize(byte[] bytes) throws SerializationException {
        if(bytes==null||bytes.length<=0){
            return null;
        }
        String string = new String(bytes, DEFAULT_CHARSET);
        return (T)JSON.parseObject(string,clazz);
    }
}

注意事项：ParserConfig.getGlobalInstance().setAutoTypeSupport(true) 一定要设置为true

Redis配置类

@Configuration
public class RedisConfig {

    @Bean
    public RedisSerializer redisSerializer(){
        return new Fast2JsonSerialize<Object>(Object.class);
    }

    @Bean
    public RedisTemplate redisTemplate(RedisConnectionFactory factory,RedisSerializer fastSerializer){

        RedisTemplate template = new RedisTemplate();
        template.setConnectionFactory(factory);

        template.setKeySerializer(new StringRedisSerializer());
        template.setValueSerializer(fastSerializer);

        template.setHashKeySerializer(new StringRedisSerializer());
        template.setHashValueSerializer(fastSerializer);

        return template;
    }
}
