【报错】org.springframework.validation.BindException: org.springframework.validation.BeanPropertyBinding

一、错误

springframework数据绑定错误：

源码如下：

org.springframework.validation.BindException: org.springframework.validation.BeanPropertyBindingResult: 1 errors
Field error in object 'position' on field 'professionId': rejected value [{"query_startDate":null,"query_endDate":null}]; codes [typeMismatch.position.professionId,typeMismatch.professionId,typeMismatch.java.lang.Long,typeMismatch]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [position.professionId,professionId]; arguments []; default message [professionId]]; default message [Failed to convert property value of type [java.lang.String] to required type [java.lang.Long] for property 'professionId'; nested exception is java.lang.NumberFormatException: For input string: "{"query_startDate":null,"query_endDate":null}"]

二、原因

这里是因为前台传来的参数不对，前来传过来一个id，跟后台的参数professionId不匹配，修改前台传过来参数即可；
