The following is a generic "Send an email to a user" endpoint, in a java application with SpringBoot framework.

Hitting it manually with Postman works as intended, but hitting it from the mobile frontend (largely react JS based) with the following JSON:

{recipientAddress: '[email protected]', subjectLine: 'a', messageBody: 's'}  

Throws the following error:

Required request body is missing: public boolean 
    [. . .].Controllers.API.ApplicationUserController.sendEmail([. . .].Models.DTOs.EmailDTO)

I don't know where this would be coming from, as the RequestBody does not have a boolean, and the DTO it does request also does not have a boolean anywhere in it. The only boolean involved is the return value, but that wouldn't be relevant to the exception in question.

CodePudding user response：

Remove @RequestBody. If your DTO will look like this

public class EmailDTO{
  private String recipientAddress;
  private String subjectLine;
  private String messageBody;
  //add getters and setters (MANDATORY)
}

and if you send all your params as query params, it will work

if you are indeed need to sent JSON than probably you wanted @PostMapping not @GetMapping

CodePudding user response：

you should not use GET with payload as {recipientAddress: '[email protected]',...}

you can either:

1. change @GetMapping("/SendEmail") to @PostMapping("/SendEmail") and send an object (don't forget content-type header)

curl -X POST http://localhost:8080/SendEmail -d '{"recipientAddress": "[email protected]", "subjectLine": "a", "messageBody": "s"}' -H 'Content-Type: application/json'

(on postman make sure to change http method to POST)

2. keep @GetMapping but break you payload into query params:

curl "http://localhost:8080/[email protected]&subjectLine=a&messageBody=s"

(assuming localhost:8080)

last you did not specify if you use class level annotation @RestController or @Controller, if you use @Controller - you should also add @ResponseBody on method level (use @RestController if you can)
