Java Jersey使用GET返回仅返回一些字段而不是全部字段的JSON

Question

Does naybody knows a way to use Jersey's GET method to return a JSON that returns only some fields of an entity instead of all? Does anybody know a way to use Jersey's GET method to return a JSON that returns only some fields of an entity instead of all? Eg in the following class I want to receive (with POST) values for 'name' and for 'confidential', buy while returning (with GET) I only need 'name' value, not 'confidential'.

@Entity
@Table(name = "a")
@XmlRootElement
@JsonIgnoreProperties({"confifentialInfo"})
public class A extends B implements Serializable {
    private String name;
    @Basic(optional = false)
    private String confifentialInfo;
    // more fields, getters and setters
}

Answer 1

If you are using the JAXB approach, you can mark fields with @XmlTransient to omit them. If you are using POJO mapping or want to exclude fields only for some requests, you should construct the JSON with the low level JSON API .

Answer 2

If you are using Jackson, you can use the annotation @JsonIgnore for methods

Marker annotation similar to javax.xml.bind.annotation.XmlTransient that indicates that the annotated method is to be ignored by introspection-based serialization and deserialization functionality. That is, it should not be consider a "getter", "setter" or "creator".

And @JsonIgnoreProperties for properties

Annotation that can be used to either suppress serialization of properties (during serialization), or ignore processing of JSON properties read (during deserialization).
