Pros and Cons of Using Lombok in Java Development

Lombok is a Java library that can automatically generate common methods like setter, getter, toString, and equals, reducing boilerplate code and improving development efficiency.

To use Lombok, add the following Maven dependency:

<dependency>
  <groupId>org.projectlombok</groupId>
  <artifactId>lombok</artifactId>
  <version>1.18.10</version>
  <scope>provided</scope>
</dependency>

A simple class with Lombok can be written as:

import lombok.Data;
@Data
public class User {
    private String id;
    private String name;
    private String desc;
}

Lombok provides many useful annotations, such as:

@NonNull – null‑pointer check

@Cleanup – automatic resource closing

@Getter/@Setter – generate getters and setters

@ToString – generate toString method

@EqualsAndHashCode – generate equals and hashCode

@NoArgsConstructor, @RequiredArgsConstructor, @AllArgsConstructor – constructors

@Data – combines @ToString, @EqualsAndHashCode, @Getter, @Setter, @RequiredArgsConstructor

@Builder – builder pattern

@SneakyThrows – suppress checked exceptions

@Synchronized – synchronized method with automatic lock

@Log and related annotations – logging utilities

Example with multiple Lombok annotations and a main method:

import lombok.*;
import java.io.FileInputStream;
import java.io.InputStream;

@Data
@NoArgsConstructor
@AllArgsConstructor
@Builder
public class User {
    private String id;
    private String name;
    private String desc;

    public static void main(String[] args) {
        new User();
        new User("juice-resume", "果汁简历", "专注于 Java 方向技术分享");
        User user = User.builder().id("juice-resume").name("果汁简历").desc("专注于 Java 方向技术分享").build();
    }

    @SneakyThrows
    private void read() {
        @Cleanup InputStream inputStream = new FileInputStream("");
    }

    @Synchronized
    public void write() {
        System.out.println("write");
    }
}

While Lombok offers clear benefits, it also has drawbacks:

1. IDE Dependency

Using Lombok requires installing a plugin in IDEs like IntelliJ IDEA, adding extra setup for new developers.

2. JDK Compatibility

Some Lombok versions may not be compatible with newer JDK releases (e.g., moving from Java 8 to Java 11), though workarounds like Delombok exist.

3. Debugging Difficulty

Generated methods are not present in source code, making step‑through debugging harder, especially for developers preferring a rich domain model.

Overall, the efficiency gains outweigh the disadvantages for most projects, and Lombok is recommended as a productivity tool rather than a core architectural decision.
