序列化继承的类时，jaxb auto生成'type'字段

Question

我正在使用Java中的jax-rs创建REST服务。我有以下型号：

@XmlSeeAlso({Student.class, Teacher.class})
public abstract class Person {    
    @XmlElement
    public String name;
}

@XmlRootElement
public class Student extends Person {

    @XmlElement
    public int classNo;
}

@XmlRootElement
public class Teacher extends Person {

    @XmlElement
    public String qualification;
}

我创建了一个类来打包响应，如下所示：

@XmlRootElement
public class PersonResponse {

    @XmlElement
    public Person person;
}

现在，我有以下资源类：

@Path("person")
public class ApiResource {

    @GET
    @Path("student")
    @Produces(MediaType.APPLICATION_JSON)
    public PersonResponse student() {
        Student person = new Student();
        person.name = "Steve";
        person.classNo = 5;
        PersonResponse response = new PersonResponse();
        response.person = person;
        return response;
    }

    @GET
    @Path("teacher")
    @Produces(MediaType.APPLICATION_JSON)
    public PersonResponse teacher() {
        Teacher person = new Teacher();
        person.name = "John";
        person.qualification = "Math";
        PersonResponse response = new PersonResponse();
        response.person = person;
        return response;
    }
}

当我访问student端点时，我得到以下结果：

{"person":{"type":"student","name":"Steve","classNo":5}}

当我访问teacher端点时，我得到以下结果：

{"person":{"type":"teacher","name":"John","qualification":"Math"}}

如您所见，为继承的类'type'和Teacher的名称派生了一个额外的字段Student。

我想知道如何禁用自动生成此字段？
