Boost Your Coding Speed: 12 Must‑Have IntelliJ IDEA Plugins for Java and Frontend

Lombok

Lombok adds handy annotations to Java projects, automatically generating boilerplate code such as getters, setters, toString, equals, hashCode, and null‑checks.

Example: adding @Getter and @Setter to a class generates the corresponding methods.

/**
 * Modify order fee information parameters
 * Created by macro on 2018/10/29.
 */
@Getter
@Setter
public class OmsMoneyInfoParam {
    private Long orderId;
    private BigDecimal freightAmount;
    private BigDecimal discountAmount;
    private Integer status;
}
