How to send json file with 2 different values?-CodePudding

I send JSON file (now from postman) the body is like this:

{
    "email": "[email protected]",
    "password": "123456"
}

the method on the controller is:

public Company getCompanyDetailsByEmailAndPassword(String email, String password) {
        System.out.println("this is email: "  email); // added the sysout to understand what arrived.
        System.out.println("this is password: "  password);
        return companyRepository.findByEmailAndPassword(email, password);
    }

I get an error -

this is email: {
    "email": "[email protected]",
    "password": "123456"
}

this is password: null

how to resolve that?

Simplest way is to write a simple class

public class EmailIdHolder {
  public String email;
  public String password;
  // add setters and getters here
}

Change your controller method to:

public Company getCompanyDetailsByEmailAndPassword(EmailIdHolder id) {
        System.out.println("this is email: "  id.getEmail); // added the sysout to understand what arrived.
        System.out.println("this is password: "  id.getPassword);
        return companyRepository.findByEmailAndPassword(email, password);
    }

Since the payload itself is a String (in JSON format), the email parameter is being assigned the entire JSON text.

I'd suggest using a single parameter instead, with a type (maybe named something like "Account") that contains an email field and a password field. Then Spring knows that the two JSON fields belong to a single instance of that class, and you can access the fields of that instance.
