@RequestBody
You can use the @RequestBody
annotation to have the request body read and deserialized into an
Object
through an HttpMessageConverter
.
The following example uses a @RequestBody
argument:
-
Java
-
Kotlin
@PostMapping("/accounts")
public void handle(@RequestBody Account account) {
// ...
}
@PostMapping("/accounts")
fun handle(@RequestBody account: Account) {
// ...
}
You can use the Message Converters option of the MVC Config to configure or customize message conversion.
You can use @RequestBody
in combination with jakarta.validation.Valid
or Spring’s
@Validated
annotation, both of which cause Standard Bean Validation to be applied.
By default, validation errors cause a MethodArgumentNotValidException
, which is turned
into a 400 (BAD_REQUEST) response. Alternatively, you can handle validation errors locally
within the controller through an Errors
or BindingResult
argument,
as the following example shows:
-
Java
-
Kotlin
@PostMapping("/accounts")
public void handle(@Valid @RequestBody Account account, BindingResult result) {
// ...
}
@PostMapping("/accounts")
fun handle(@Valid @RequestBody account: Account, result: BindingResult) {
// ...
}
