@RequestBody @Valid アノテーションを使用して、Spring で Bean の検証とデータ マッピングを行おうとしています。
エンティティ Bean でわかるように、@NotNull アノテーションと @Min アノテーションを使用しています。どちらも異なる検証メッセージを使用しており、コントローラーのBindingResult引数でこのメッセージを読み取ることができます。
しかし、クライアントが "operatorId" フィールドにlongではなくString値を送信すると、以下に示すエラーが表示されます。
私の質問は:
クライアントが operatorId に数値以外の文字列値を設定したときに、エラー メッセージ テキストをクライアントに返したいと考えています。(例:「数値などを送信する必要があります」)
エンティティ Bean :
@Entity(name="ua")
@Table(name="ua")
public class UserAgreement extends BaseContractEntity {
@Column(name = "OPERATOR_ID")
@NotNull(message = "operatorId must be provided")
@Min(value = 1, message = "operatorId must be bigger then zero")
protected long operatorId;
//... getters setters, etc
}
コントローラー：
@RequestMapping(value = "/ug", method = RequestMethod.POST)
@ResponseBody
public ServiceResponse saveUserAgreement(@RequestBody @Valid UserAgreement userAgreement,
BindingResult result) {
ServiceResponse serviceResponse = new ServiceResponse();
if(result.hasErrors()) {
serviceResponse.setMessage(result.getAllErrors().get(0).getDefaultMessage());
serviceResponse.setErrorCode("400");
return serviceResponse;
} else {
// call service
serviceResponse.setMessage("ok");
return serviceResponse;
}
}
これは私のリクエストの例です:
この json テキストを使用して POST リクエストを行う場合 (間違った operatorId 非数値! ):
{"content":"text content text","announcement":"YES","approved":"YES","operatorId":"5fg0"}
このエラーを取得:
