Spring post method "Required request body is missing"

Question

@PostMapping(path="/login")
public ResponseEntity<User> loginUser(@RequestBody Map<String, String> userData) throws Exception {
    return ResponseEntity.ok(userService.login(userData));
}

I have this method for the login in the UserController. The problem is when i try to make the post request for the login i get this error:

{
"timestamp": "2018-10-24T16:47:04.691+0000",
"status": 400,
"error": "Bad Request",
"message": "Required request body is missing: public org.springframework.http.ResponseEntity<org.scd.model.User> org.scd.controller.UserController.loginUser(java.util.Map<java.lang.String, java.lang.String>) throws java.lang.Exception",
"path": "/users/login"
}

Hi! what is the body you are passing to your API? – Reserpine

Do i need to pass the email and password in Body? – Starobin

Depends, you can do on both ways, se my anwer :D – Reserpine

Answer 1

You have to pass that as JSON in your body, if it's a POST request.

Change Media type Text to JSON as I have done in the picture above. – Cristicristian

for some case (happened to me), it must be added headers information. – Sevenup

Answer 2

I had a similar issue, was getting this error in my Spring Boot service

HttpMessageNotReadableException: Required request body is missing:...

My issue was that, when I was making requests from Postman, the "Content-Length" header was unchecked, so service was not considering the request body.

This is happening because you are not passing a body to you server. As can I see in your screenshot you are passing email and password as a ResquestParam.

To handle this values, you can do the following:

@PostMapping(path="/login")
public ResponseEntity<User> loginUser(@RequestParam("email") String email, @RequestParam("password") String password) {
     //your imp
}

In order to accept an empty body you can use the required param in the RequestBody annotation:

@RequestBody(required = false)

But this will not solve your problem. Receiving as RequestParam will.

If you want to use RequestBody you should pass the email and password in the body.

To receive RequestParam in POST you can refer to this question: #17965341 You can also pass the data through the body, which makes sense too, since it is a post request. – Reserpine

The @RequestBody for the Type doesn't work, but actual Type parameters work? Wonder why? – Vikkivikky

this solution works for me, make sure on postman you're sending the post with the parameters as well – Gaffrigged

Answer 4

If it's still not working, try adding additional information UTF-8 in Headers.

key : Content-Type value : application/json; charset=utf-8

For my case, I must adding UTF-8 in Headers.

Same case with me – Boanerges

Answer 5

You need to send data in Body as JSON

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

@lonut click raw – Starlet

@lonut click on text combo and change to json – Starlet

Answer 6

In my case it was poorly defined JSON that I sent to my REST service.

Attribute that was suppose to be an object, was in my case just string:

Changed from:

"client" = "",

to:

"client" = { ... },

In my case String did not add additional information about value in different format.

Answer 7

In my case, adding such header 'Content-Type: application/x-www-form-urlencoded' solves the issue. The servlet do have the @RequestBody part. I assume Spring will need such header to form the post body

Answer 8

If it is XML Request Try importing jackson-dataformat-xml.jar to your project it worked for me.

Answer 10

I was encountering the same issue, turns out that my JSON body was not valid. I mindlessly added some Java style comments which made it invalid.
