简介: FeignClient【问题】Cannot deserialize value of type``from Object value (token `JsonToken.START_OBJECT`) 1. 问题描述 @FeignClient(name = "dataServiceQueryInterface", url = "${url}:${port}") public interface DataServiceQueryInterface { @GetMapping("/dataReport/getSysAreaAllList") List<...
cannot deserialize from Object value (no delegate- or property-based Creator) result方法需要无参构造器 在result中添加一个无参构造器解决问题 __EOF__
@FeignClient(value="service-demo")publicinterfaceDemoFeignClient {//调用的请求路径@RequestMapping(value ="/demo/{id}",method =RequestMethod.GET)publicServerResponse<Demo>getById(@PathVariable Integer id); }
此处报错信息: com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Cannot construct instance of `org.example.pojo.Student` (no Creators, like default construct, exist): cannot deserialize from Object value (no delegate- or property-based Creator) 报错的对象 :org.example.pojo.Student 如下,...

no Creators, like default construct, exist: cannot deserialize from Object value no delegate- or property-based Creator 为了排查问题,首先想到本地复现问题。本地启动dialog和enduser服务,postman请求dialog服务的接口/dialog/nextQuestion。却出现另一个问题,且这个报错发生在解析requestBody时。在Controller层方法里...

Feign远程调⽤序列化对象失败 最近在搭建⼀个SpringCloud的微服务时，遇到了⼀个问题，在使⽤Feign远程调⽤时报错，返回对象没有⽆参构造⽅法，有其他的含参数的构造⽅法。本地⾃⼰搭建的微服务⽬录⼤概如下，才刚开始，后续会逐渐补充优化迭代，有兴趣的可以fork下地址：给与指导意见。Eureka：...
