How to send data as @RequestPart in the postman-CodePudding

I just joined a new project and I'm having trouble creating an object that has an @RequestPart annotation in the controller

Here are images of the model:

Here is the controller:

And the service:

How should I send the request to create the Deliverable object?

I tried a few ways but always get the error : request does not contain multipart/form-data or multipart/mixed stream, content type header is application/json

Thank you for your help!

EDITED:

Below are the images of the postman configuration

CodePudding user response：

Here is the way you can do it, use this example and change it according to your scenario -

In the post man select POST operation on appropriate endpoint and then follow these steps -

In postman set the header Content-type to multipart/form-data.
In the body section choose form-data and set appropriate key (in the example it's set to employee) and type should be file
In the value select the employee input file (json), here is what my example json file looks like -

Then you can send the request and it should work as expected.

Here is the cURL that you can use in postman to check header and request.

curl --location --request POST 'http://localhost:8081/employee' --header 'Content-Type: multipart/form-data' --header 'Cookie: JSESSIONID=8A3EEB5DA1F992DCC5B879CBF538000D' --form 'employee=@"/C:/Users/ASUS/Desktop/employee.json"'
