Recently encountered in 400,

I used to think that 400 was the result of a parameter mismatch until today.

The console error is as follows:

Com.fasterxml.jackson.databind.JsonMappingException:Can not construct instance of Com.infs.xyc.vo .....


The reason is: in the class that encapsulates the parameter, override the construction method with the parameter, but forget to generate the default construction Method!!!

The Request:jackson turns the JSON string into List<object>, exception com.fasterxml.jackson.databind.JsonMappingException
