@ResponseBody
You can use the @ResponseBody
annotation on a method to have the return serialized
to the response body through an HttpMessageWriter. The following
example shows how to do so:
-
Java
-
Kotlin
@GetMapping("/accounts/{id}")
@ResponseBody
public Account handle() {
// ...
}
@GetMapping("/accounts/{id}")
@ResponseBody
fun handle(): Account {
// ...
}
@ResponseBody
is also supported at the class level, in which case it is inherited by
all controller methods. This is the effect of @RestController
, which is nothing more
than a meta-annotation marked with @Controller
and @ResponseBody
.
@ResponseBody
supports reactive types, which means you can return Reactor or RxJava
types and have the asynchronous values they produce rendered to the response.
For additional details, see Streaming and
JSON rendering.
You can combine @ResponseBody
methods with JSON serialization views.
See Jackson JSON for details.
You can use the HTTP message codecs option of the WebFlux Config to configure or customize message writing.
