代码中注入一个bean即可:
/**
* 解决Jackson导致Long型数据精度丢失问题
*
* @return
*/
@Bean("jackson2ObjectMapperBuilderCustomizer")
public Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilderCustomizer() {
Jackson2ObjectMapperBuilderCustomizer customizer = jacksonObjectMapperBuilder -> jacksonObjectMapperBuilder.serializerByType(Long.class, ToStringSerializer.instance)
.serializerByType(Long.TYPE, ToStringSerializer.instance);
return customizer;
}
