I promise input json strings are same,but The Dto’s Field around @RequestBody always null;
version
JDK8,17 springboot2.0,3.3 jackson 2.11,2.14
input strings
{ "user": { "name": "John Doe", "email": "[email protected]", "location": { "street": "123 Main St", "city": "Springfield" } } }
@RestController
@RequestMapping("/test")
public class TestController {
@PostMapping(value = "/get", consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
public boolean getInfo(@RequestBody UserDTO userDTO) throws JsonProcessingException {
String json = "{ "user": { "name": "John Doe", "email": "[email protected]", "location": { "street": "123 Main St", "city": "Springfield" } } }";
ObjectMapper mapper = new ObjectMapper();
mapper.enable(DeserializationFeature.UNWRAP_ROOT_VALUE);
UserDTO user = mapper.readValue(json, UserDTO.class);
return true;
}
}
application.yml
spring:
serialization:
WRAP_ROOT_VALUE: true
deserialization:
UNWRAP_ROOT_VALUE: true
I have tried add a wrapperDTO to replace the @JsonRootName
but Any else clear method can make @JsonRootName work ?
It can prevent me editing too much code if @JsonRootName work well with @RequestBody.

Your configuration is using the wrong property.
spring:
serialization:
WRAP_ROOT_VALUE: true
deserialization:
UNWRAP_ROOT_VALUE: true
spring.serialization is not a valid property. What you wanted to use was the spring.jackson.serialization property.
spring:
jackson:
serialization:
WRAP_ROOT_VALUE: true
deserialization:
UNWRAP_ROOT_VALUE: true
This should work.
For a list of properties to use for JSON configuration consult the documentation. For more information on Jackson specific you can check this part of the documentation which also explains a bit more about what property to use for what.
