“HttpMessageNotReadableException Required request body is missing” when trying to make a post request

Question

I have a controller class with a few methods one of which is a method that is supposed to take POST requests and create a new Account with the JSON from the body of that POS

Answer 1

You cannot use multiple @RequestBody. You need to wrap everything into a class that will be used to match your request body.

The same is answered also here.

There is also a JIRA issue for a feature request which was rejected.

NOTE: if you want to write less, you can use @PostMapping instead of @RequestMapping(method = RequestMethod.POST).

NOTE: @RequestParam and @PathVariable are used to extract data from URI, not from body.

NOTE: the same is valid also for the equivalent [FromBody] attribute from ASP.NET WebAPI.

Complete example:

Bellow I created a working example similar to your case:

Request DTO

public class AccountCreateRequest {

    private String userName;
    private String password;

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

Response DTO

public class AccountCreateResponse {

    private String userName;
    private String password;

    public AccountCreateResponse() {
    }

    public AccountCreateResponse(String userName, String password) {
        this.userName = userName;
        this.password = password;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

Controller

@RestController
@RequestMapping("/v1/account")
public class AccountController {

    @PostMapping(produces = MediaType.APPLICATION_JSON_VALUE)
    public @ResponseStatus(HttpStatus.CREATED) AccountCreateResponse add(@RequestBody() AccountCreateRequest account) {
        AccountCreateResponse response = new AccountCreateResponse(account.getUserName(), account.getPassword());
        return response;
    }
}

curl request

curl -X POST --data '{"userName":"bepis", "password":"xyz"}' -H "Content-Type:application/json" http://localhost:8080/v1/account
