SpringMVC返回json数据时，Long字段丢失精度

实体类的id，java为Long，数据库为Bigint,从数据库查询返回时是正确的，但是将实体响应的时候19位的Long类型id精度丢失。
解决方案一：
字段加注解，返回时将此字段序列化为string类型

@Data
public class User {
    @TableId(value = "id",type = IdType.ASSIGN_ID)
    @JsonSerialize(using = ToStringSerializer.class)
    private Long id;
    private String name;
}

解决方案二：
全局配置

@Configuration
public class WebConfig implements WebMvcConfigurer {
    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        MappingJackson2HttpMessageConverter jackson2HttpMessageConverter = new MappingJackson2HttpMessageConverter();
        ObjectMapper objectMapper = new ObjectMapper();

        SimpleModule simpleModule = new SimpleModule();
        simpleModule.addSerializer(Long.class, ToStringSerializer.instance);
        simpleModule.addSerializer(Long.TYPE, ToStringSerializer.instance);
        objectMapper.registerModule(simpleModule);

        jackson2HttpMessageConverter.setObjectMapper(objectMapper);
        converters.add(0,jackson2HttpMessageConverter);

    }
}
