Lombok. This article describes how to use Lombok for the creation of data/model objects.

1. Introduction to lombok

The offical lombok website can be found here: https://projectlombok.org/

Lombok is used to reduce boilerplate code for model/data objects, e.g., it can generate getters and setters for those object automatically by using Lombok annotations. The easiest way is to use the @Data annotation.

package de.vogella.jpa.simple.model;

import lombok.Data;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

public class Todo {
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    private String summary;
    private String description;

By simply adding the @data annotation you get all this for free:

2. Enable lombok for Eclipse or Spring Tool Suite

You can download the latest lombok version from https://projectlombok.org/download.html or by using Gradle, Maven or other tools.

The lombok.jar can be copied into the root Eclipse or Spring Tool Suite folder and run like this:

java -jar lombok-1.16.12.jar

This will open a small UI, where the location of the Eclipse installation can be specified. Usually the Eclipse installation will be found automatically and lombok can be installed or updated.
