define request body in spring colud contract

Question

I want to write a contract using spring cloud contract in producer API.

Here is my API:

    @PostMapping(path = "/person",
        produces = {MediaType.APPLICATION_JSON_VALUE}, consumes = {MediaType.APPLICATION_JSON_VALUE})
public ResponseEntity<PersonInfo> test(@RequestBody PersonRequest request){
    PersonInfo personInfo = bankService.getPersonInfo(request);
    return new ResponseEntity<>(personInfo, HttpStatus.OK);
}

My DSL in groovy :

  Contract.make {
   description("spring cloud contract")
   request {
   method 'POST'
   url '/person'
   headers {
    contentType(applicationJson())
  }
   body("""
 {
   "nationalId": "2548745"
 }
    """)

 }
  response {
 status 200
 body("""
 {
   "name": "Marc",
   "family": "Brown",
   "gender": "M"
}
""")
  headers {
     contentType(applicationJson())
   }
  }
}

PersonRequest :

public class PersonRequest {
private String nationalId;


public String getNationalId() {
    return nationalId;
}

public void setNationalId(String nationalId) {
    this.nationalId = nationalId;
}

}

Now when I clean and install the project I get this error :

Expecting: <415> to be equal to: <200> but was not.

If I change @RequestBody PersonRequest request to @RequestBody String request everything works fine.

I am using spring boot 2.3.1.RELEASE and spring-cloud-starter-contract-verifier 2.2.3.RELEASE and junit5

I test this case with junit4 and it is ok. How can I fix this problem?

Don't change the dsl, change the base class

RestAssuredMockMvc.config = new RestAssuredMockMvcConfig() .encoderConfig(new EncoderConfig(UTF_8.name(), UTF_8.name()));

or opt-out appending of default content charset:

EncoderConfig encoderConfig = new EncoderConfig() .appendDefaultContentCharsetToContentTypeIfUndefined(false); RestAssuredMockMvcConfig restAssuredConf = new RestAssuredMockMvcConfig() .encoderConfig(encoderConfig); RestAssuredMockMvc.config = restAssuredConf;
