问题springboot后台返回的id，前台接口获取数据错误异常？，亲测有效

1.id是long类型，需转成string，失真

@Configuration
public class BladeConfiguration implements WebMvcConfigurer {

	@Bean
	public Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilderCustomizer() {
		return jacksonObjectMapperBuilder -> jacksonObjectMapperBuilder
			.serializerByType(Long.class, ToStringSerializer.instance)
			.serializerByType(Long.TYPE, ToStringSerializer.instance);
	}
}

我这边是 BladeConfiguration类，随便你取名，只要实现 WebMvcConfigurer
