杰克逊：从json中删除一些值并保留一些空值

使用@JsonView批注可能对您有用

public class Views {    public static class Public {    }    public static class base {    } }public class Employee {   @JsonProperty("emplyee_id")   @JsonView({View.Public.class,View.base.class})   private Integer id;   @JsonProperty("emplyee_first_name")   @JsonView(View.Public.class)   private String firstName;   @JsonProperty("emplyee_last_name")   @JsonView(View.Public.class)   private String lastName;   @JsonProperty("emplyee_address")   private String address;   @JsonProperty("emplyee_age")   private Byte age;   @JsonProperty("emplyee_level")   @JsonView(View.base.class)   private Byte level;   //getters and setters }

在您的json响应中添加@JsonView（Public / base.class），它将基于jsonview批注返回

//requestmapping@JsonView(View.Public.class)  public ResponseEntity<Employee> getEmployeeWithPublicView(){    //do something}

响应：

{   "employee_id":101,  "employee_first_name":"Alex",  "employee_last_name":"Light",  "employee_age":null,  "employee_address":null}

第二个

//requestmapping@JsonView(View.base.class)  public ResponseEntity<Employee> getEmployeeWithbaseView(){    //do something}

响应

{   "employee_id":101,   "employee_level":5}
