Jackson - prevent field serialization with @JsonIgnore

In this short article, we would like to show how to ignore some fields serialization working with Jackson library.

Quick solution (use @JsonIgnore annotation):

xxxxxxxxxx

package com.example;

​

import javax.persistence.Entity;

import javax.persistence.Table;

import com.fasterxml.jackson.annotation;

​

@Entity

@Table(name = "users")

public class UserEntiy {

​

    // some fields here ...    

​

    @JsonIgnore

    String ignoredField;

​

    // some fields here ...   

}

Note: @JsonIgnore causes the field will be omitted and not serialized by Jackson (use @JsonProperty to get same effect on deserialization).
