Ali FastJson open source framework JSON a high-performance, fast FastJson data processing speed, regardless of the sequence (to be converted into a JavaBean Json string format) and deserialization (JSON-formatted string into the object Java Bean) are worthy of the fast; powerful (JDK support the general categories, including javaBean, Collection, Date, or enum); zero-dependent (not dependent on any other libraries).

1, to write a custom serialization class

/**
 * 自定义序列化类
 * @param <T>
 */
public class FastJsonRedisSerializer<T> implements RedisSerializer<T> {

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

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

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

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

}

2, write a Redis configuration class

@Configuration
public class RedisConfiguration {

    @Bean
    public RedisTemplate<Object, Object> redisTemplate(
            RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<Object, Object> template = new RedisTemplate<>();
        //使用fastjson序列化
        FastJsonRedisSerializer fastJsonRedisSerializer = new FastJsonRedisSerializer(Object.class);
        // value值的序列化采用fastJsonRedisSerializer
        template.setValueSerializer(fastJsonRedisSerializer);
        template.setHashValueSerializer(fastJsonRedisSerializer);
        // key的序列化采用StringRedisSerializer
        template.setKeySerializer(new StringRedisSerializer());
        template.setHashKeySerializer(new StringRedisSerializer());
        template.setConnectionFactory(redisConnectionFactory);
        return template;
    }
}

3, Student category

@Data
public class Student {
    private Integer studentId;
    private String studentName;
}

4, pom.xml fastjson dependence introduction and redis, application.yml address configuration profile Remember the Redis.

5, BootRedisApplication startup class

@SpringBootApplication
public class BootRedisApplication {

    public static void main(String[] args) {
        ConfigurableApplicationContext
                context = SpringApplication.run(BootRedisApplication.class, args);
        
        Student student = new Student();
        student.setStudentId(101);
        student.setStudentName("学生A");
        
        RedisTemplate cRedisTemplate = context.getBean("redisTemplate", RedisTemplate.class);
        cRedisTemplate.opsForValue().set("student-1", student);

        context.close();
    }
}

6, see Redis data

{"@type":"com.example.bootredis.Student","studentId":101,"studentName":"学生A"}
