另一种简单的处理方法是在注释中使用allowSetters=true参数。这将允许密码被反序列化到dto中，但不会序列化到使用contains对象的响应体中。

例子:

@JsonIgnoreProperties(allowSetters = true, value = {"bar"})
class Pojo{
    String foo;
    String bar;
}

foo和bar都被填充到对象中，但只有foo被写入响应体。

从2.6版开始:更直观的方法是在字段上使用com.fasterxml.jackson.annotation.JsonProperty注释:

@JsonProperty(access = Access.WRITE_ONLY)
private String myField;

即使存在getter，该字段值也不会被序列化。

JavaDoc说:

/**
 * Access setting that means that the property may only be written (set)
 * for deserialization,
 * but will not be read (get) on serialization, that is, the value of the property
 * is not included in serialization.
 */
WRITE_ONLY

如果你需要它的其他方式，只需使用Access.READ_ONLY。

在我的例子中，我让Jackson自动(反)序列化我从Spring MVC控制器返回的对象(我在Spring 4.1.6中使用@RestController)。我不得不使用com.fasterxml.jackson.annotation.JsonIgnore而不是org.codehaus.jackson. annotation。JsonIgnore，否则，它什么也不做。

"user": {
        "firstName": "Musa",
        "lastName": "Aliyev",
        "email": "klaudi2012@gmail.com",
        "passwordIn": "98989898", (or encoded version in front if we not using https)
        "country": "Azeribaijan",
        "phone": "+994707702747"
    }

@CrossOrigin(methods=RequestMethod.POST)
@RequestMapping("/public/register")
public @ResponseBody MsgKit registerNewUsert(@RequestBody User u){

        root.registerUser(u);

    return new MsgKit("registered");
}  

@Service
@Transactional
public class RootBsn {

    @Autowired UserRepository userRepo;

    public void registerUser(User u) throws Exception{

        u.setPassword(u.getPasswordIn());
        //Generate some salt and  setPassword (encoded -  salt+password)
        User u=userRepo.save(u);

        System.out.println("Registration information saved");
    }

}

    @Entity        
@JsonIgnoreProperties({"recordDate","modificationDate","status","createdBy","modifiedBy","salt","password"})
                    public class User implements Serializable {
                        private static final long serialVersionUID = 1L;

                        @Id
                        @GeneratedValue(strategy=GenerationType.AUTO)
                        private Long id;

                        private String country;

                        @Column(name="CREATED_BY")
                        private String createdBy;

                        private String email;

                        @Column(name="FIRST_NAME")
                        private String firstName;

                        @Column(name="LAST_LOGIN_DATE")
                        private Timestamp lastLoginDate;

                        @Column(name="LAST_NAME")
                        private String lastName;

                        @Column(name="MODIFICATION_DATE")
                        private Timestamp modificationDate;

                        @Column(name="MODIFIED_BY")
                        private String modifiedBy;

                        private String password;

                        @Transient
                        private String passwordIn;

                        private String phone;

                        @Column(name="RECORD_DATE")
                        private Timestamp recordDate;

                        private String salt;

                        private String status;

                        @Column(name="USER_STATUS")
                        private String userStatus;

                        public User() {
                        }
                // getters and setters
                }

为了实现这一点，我们只需要两个注释:

@JsonIgnore @JsonProperty

在类成员及其getter上使用@JsonIgnore，在类成员的setter上使用@JsonProperty。一个示例说明将有助于做到这一点:

class User {

    // More fields here
    @JsonIgnore
    private String password;

    @JsonIgnore
    public String getPassword() {
        return password;
    }

    @JsonProperty
    public void setPassword(final String password) {
        this.password = password;
    }
}

你还可以这样做:

@JsonIgnore
@JsonProperty(access = Access.WRITE_ONLY)
private String password;

这对我很有效
