JsonIgnoreProperties无法使用spring boot

当前的Spring启动示例应用程序已创建 . 在请求中，如果有任何未知字段即将到来，那么我们需要抛出错误 .

为了这

@JsonIgnoreProperties（ignoreUnknown = false）

正在使用注释 . 但是，当我打网址时，它无法正常工作 .

请查找以下代码段：

import java.io.IOException; import java.util.List; import javax.validation.Valid; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.http.MediaType; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestBody; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RestController; import com.fasterxml.jackson.annotation.JsonIgnoreProperties; import com.fasterxml.jackson.core.JsonParseException; import com.fasterxml.jackson.core.JsonProcessingException; import com.fasterxml.jackson.databind.JsonMappingException; import com.fasterxml.jackson.databind.ObjectMapper; import com.journaldev.bootifulmongodb.dal.UserDAL; import com.journaldev.bootifulmongodb.dal.UserRepository; import com.journaldev.bootifulmongodb.model.CardInfo; import com.journaldev.bootifulmongodb.model.User; @RestController @RequestMapping（value =“/”）@JsonIgnoreProperties（ignoreUnknown = false）public class UserController {private final Logger LOG = LoggerFactory.getLogger（getClass（））;私有最终UserRepository userRepository;私人最终UserDAL userDAL; public UserController（UserRepository userRepository，UserDAL userDAL） @RequestMapping（value =“/ create”，method = RequestMethod.POST，consume = MediaType.APPLICATION_JSON_VALUE，produce = MediaType.APPLICATION_JSON_VALUE）public User addNewUsers（@RequestBody @Valid User user）throws JsonProcessingException {LOG.info（“Saving user” . “）; CardInfo cardInfo = new CardInfo（）;
cardInfo.setCardId（ “12345678901”）; user.setCardInfo（cardInfo）;
ObjectMapper mapper = new ObjectMapper（）;

String jsonString = mapper.writeValueAsString（cardInfo）;
user.setCardInfo1（jsonString）; userDAL.getAllUsers（）;返回
userRepository.save（用户）; }
