我有一个REST服务,可以输出POJO列表。响应XML / JSON包含使用XMLElement注释的所有字段。有没有办法限制响应中的字段(以编程方式运行时)?我还可以在运行时再次指定字段的顺序吗?

POJO:

 @XmlRootElement
 @XmlAccessorType(XmlAccessType.NONE)
 public class Employee {
    @XmlElement
    @Column(name="Name", length=75) @NotNull @Length(max=75)        
    private String name;   

    @XmlElement
    @Column(name="designation", length=75)       
    private String designation;   

    @XmlElement
    @Column(name="department", length=75)        
    private String department;   
}

@Path("employee")
public class EmployeeRestService {
    @GET
    @Path("json")
    @Produces(MediaType.APPLICATION_JSON)
    public Response emp() {
        return Response.ok(getDetails(), MediaType.APPLICATION_JSON).build();;
    }

    @Path("xml")
    @Produces(MediaType.APPLICATION_XML)
    public Response emp() {
        GenericEntity<List<Employee>> list = new GenericEntity<List<Employee>>(getDetails()) {};
        return Response.ok(list, MediaType.APPLICATION_XML).build();;
    }

    public List<Employee> getDetails() {
        .....
        return list;
    }
}

My output now is:
JSON:
[{name:Tom,designation:Manager,department:IT},{name:Jim,designation:Clerk,department:IT}]
XML:
<employees>
    <employee>
      <name>Tom</name>
      <designation>Manager</designation>
      <department>IT</department>
    </employee>
    <employee>
      <name>Jim</name>
      <designation>Clerk</designation>
      <department>IT</department>
    </employee>
</employees>

Desired output:
JSON:
[{designation:Manager,name:Tom},{designation:Clerk,name:Jim}]
XML:
<employees>
    <employee>
      <designation>Manager</designation>
      <name>Tom</name>
    </employee>
    <employee>
      <designation>Clerk</designation>
      <name>Jim</name>
    </employee>
</employees>

仅在提交请求时才知道字段和订单。所以像JSONIgnore这样的注释对我没用。 我该怎么做?我试过Genson。虽然我可以限制JSON响应中的字段,但我无法对XML响应进行限制。此外,我无法订购字段。

要设置自定义订单,您可以使用:

@XmlType(propOrder = {&#34; names&#34;,&#34; name&#34;,&#34; department&#34;,&#34; abcd&#34;})
