Want to pass more than two variable in the postman as a parameter.

Answer 1

Spring Boot not support multipe requestbody.

Answer 2

Not sure I understand the question, but there are many ways to pass parameters to an API.
As a JSON object
If you just want to pass multiple parameters you'd just pass them in json format in the request body as a post or a put:
{
"firstName": "bob",
"lastName": "smith",
"middleName": "joe"
}
And your controller method would look something like
public Name createName(
#RequestBody Name name
) {}
As a JSON list
If you mean you have multiple values for the same parameter then you can pass them as a list.
[
{"firstName": "bob"},
{"firstName": "joe"},
{"firstName": "jerry"}
]
And your controller method would look something like
public List<Name> nameList createName(
#RequestBody List<Name> nameList
) {}
or
{
"firstNames": [
{"firstName": "bob"},
{"firstName": "joe"},
{"firstName": "jerry"}
]
}
And your controller method would look something like
public Names createName(
#RequestBody Names names
) {}
In this example Names would be an object that contains a variable
List<Name> nameList;
In the uri
Another option to pass values to the api is to include them a path parameters
from postman your uri would look something like this:
using #RequestParam on the API
http://localhost:8080/apiPath?firstName=bob&lastName=smith&middleName=joe
or
using #PathVariable on the API
http://localhost:8080/apiPath/firstName/bob/lastName/smith/middleName/joe
