Jackson을 사용하여 JSON 객체를 Java의 열거형 유형으로 변환하는 방법은 무엇입니까?

import com.fasterxml.jackson.databind.*;
public class JSONToEnumTest {
   public static void main(String arg[]) throws Exception {
      ObjectMapper mapper = new ObjectMapper();
      Employee emp = mapper.readValue("{\"jobType\":\"CONTRACT\"}", Employee.class);
      System.out.println(emp.getJobType());
   }
   public static class Employee {
      private JobType jobType;
      public JobType getJobType() {
         return jobType;
      }
      public void setJobType(JobType jobType) {
         this.jobType = jobType;
      }
   }
   public enum JobType {
      PERMANENT,
      CONTRACT,
   }
}

CONTRACT
