Java Jackson：父类属性被忽略：将json反序列化为数据

我正在尝试将JSON（myJson.JSON）对象转换为Java类

使用以下代码

但是上面的

ObjectMapper

无法将父类（StudentDTO）映射到类属性（loggedInUser、createdBy等）。

是否有可以映射父类属性的

@注释

欢迎提出任何建议

我有以下内容-StudentInfoDTO、AddressDTO、StudentDTO、skillsdo和myJson.json

学生信息发送至：

public class StudentInfoDTO extends StudentDTO implements Serializable{
private static final long serialVersionUID = 1L;
private AddressDTO address;
private String studentName;
....getters and setters

}

 public class AddressDTO implements Serializable{
    private static final long serialVersionUID = 1L;
    private String street;
    private String city;
    private String state;
    private String country;
    private Long zipcode;
    ....getters and setters

    }

 public class StudentDTO implements Serializable{
    private static final long serialVersionUID = 1L;
    private String loggedInUser;
    private String createdBy;
    private Date createdTs;
    private String updatedBy;
    private Date updatedTs;
    private List<skillsDTO> skills;
    ....getters and setters

    }

很抱歉给您带来不便

它像预期的那样工作。 我的

myJson.json

文件中有一个错误，我按照

@Vishvesh Phadnis

的建议重新生成了getter和setter

{
   "address": 
      {
        "street": "Hunterfly Place",
        "city": "Dunlo",
        "state": "Arizona",
        "country": "Colorado",
        "zipcode": "1631"
      },
    "studentName": "John",

    "loggedInUser": "Admin",
    "createdBy": "System",
    "createdTs": "03-19-2011 14:53",
    "updatedBy": "John",
    "updatedTs": "06-11-2014 08:00",
    "skills": [
        {
            "skill": "Football",
            "grade": "A"
        },
        {
            "skill": "Swimming",
            "grade": "C"
        },
        {
            "skill": "Dance",
            "grade": "A"
        }]

    }

谢谢大家：）

您正在使用哪个库版本？我没有面临任何问题。@VishveshPhadnis这是我在pom.xml

org.codehaus.jackson-jackson映射器asl 1.8.5中的内容。

@VishveshPhadnis我与JDK1.7、Jboss 7.1.1和jackson 1.8.5一起使用。我认为您没有为所有类添加正确的getter和setter。请交叉检查。特别是在

StudentDTO

class@VishveshPhadnis我有能手和二传手
