so i've been trying to implement a jwt authentication/authorization example , i am trying to register a new user using postman but the post procedure couldn't be completed because of attribute "role" that is declared as a "Set" , i tried putting the attribute role as null like this:
{
"id": 1,
"username": "jacksonBez",
"email": "[email protected]",
"role":"",
"password": "123bezko"
}
and this warning has occured :
.w.s.m.s.DefaultHandlerExceptionResolver : Resolved [org.springframework.http.converter.HttpMessageNotReadableException: JSON parse error: Cannot coerce empty String ("") to element of
java.util.HashSet<java.lang.String>(but could if coercion was enabled usingCoercionConfig); nested exception is com.fasterxml.jackson.databind.exc.InvalidFormatException: Cannot coerce empty String ("") to element ofjava.util.HashSet<java.lang.String>(but could if coercion was enabled usingCoercionConfig) at [Source: (org.springframework.util.StreamUtils$NonClosingInputStream); line: 5, column: 13] (through reference chain: com.test.jwt.payload.request.SignUpRequest["role"])]
i want to know how to use postman with a variable declared a list or a Set

thank you.
CodePudding user response：
{
"id": 1,
"username": "jacksonBez",
"email": "[email protected]",
"role": {{roles}},
"password": "123bezko"
}
You are missing brackets []. "role": "" means single value "role": [] means array/list/set of values For postman to resole {{role}} you need to set it as global/collection or environment value for example ["admin", "mod"]
