雪花算法生成id长度过长处理

思路：将Long类型转成字符串

代码实现：

import com.fasterxml.jackson.databind.ser.std.ToStringSerializer;
import org.springframework.boot.autoconfigure.jackson.Jackson2ObjectMapperBuilderCustomizer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class JacksonConf {

    /**
     * 自定义序列化类型转换
     * 注：此处解决Long型转换后，前端js损失精度的问题，将Long型转换为字符串类型
     */
    @Bean
    public Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilderCustomizer() {
        Jackson2ObjectMapperBuilderCustomizer customizer = jacksonObjectMapperBuilder ->
                jacksonObjectMapperBuilder.serializerByType(Long.class, ToStringSerializer.instance)
                        .serializerByType(Long.TYPE, ToStringSerializer.instance);
        return customizer;
    }
}
