20 Must‑Have IntelliJ IDEA Plugins to Supercharge Your Development

Key Promoter X

Key Promoter X helps you quickly learn IDEA shortcuts by automatically showing the shortcut when you click a function with the mouse, encouraging keyboard‑only development.

When using the mouse to perform actions, Key Promoter X displays the corresponding shortcut.

Lombok

Lombok is a Java code‑enhancement library; its annotations generate getters, setters, equals, and other methods at compile time, eliminating boilerplate code.

Example: adding

@Getter

and

@Setter

to a class automatically creates the methods.

<code>@Getter
@Setter
public class OmsMoneyInfoParam {
    @ApiModelProperty("订单ID")
    private Long orderId;
    @ApiModelProperty("运费金额")
    private BigDecimal freightAmount;
    @ApiModelProperty("管理员后台调整订单所使用的折扣金额")
    private BigDecimal discountAmount;
    @ApiModelProperty("订单状态：0->待付款；1->待发货；2->已发货；3->已完成；4->已关闭；5->无效订单")
    private Integer status;
}
</code>

Lombok will automatically generate getters and setters for all fields.

MyBatisX

MyBatisX, developed by the MyBatis‑Plus team, provides fast development features such as navigation between XML and mapper interfaces and a graphical code generator that can create SQL implementations from method names.

Clicking the icon next to a mapper method jumps to the corresponding XML, and vice versa.

When a method follows JPA conventions, SQL is generated automatically without manual coding.

RestfulFastRequest

RestfulFastRequest is an IDEA‑based Restful API toolkit that generates request test cases from existing methods, offers a beautiful UI for sending requests, inspecting responses, and exporting API definitions.

The plugin provides a convenient interface for debugging APIs directly within IDEA.

PlantUML is an open‑source UML diagram tool that generates graphics from plain text, supporting sequence, class, object, activity diagrams, and mind maps.

It allows real‑time preview of diagrams, such as flowcharts.

SequenceDiagram

SequenceDiagram generates sequence diagrams from code, supports navigation from diagram to source, and can export to image or PlantUML format.

The plugin produces clear sequence diagrams for visualizing method calls.

GsonFormatPlus

GsonFormatPlus automatically generates Java entity classes from JSON strings and supports Lombok annotations.

Select text, right‑click, and choose the desired operation from the menu.

MapStruct support

MapStruct is a Java annotation‑based mapper that generates implementation classes without reflection, offering high performance.

The IDEA plugin suggests mapping properties and enables navigation to the target fields.

Alibaba Java Coding Guidelines

The Alibaba Java Development Manual plugin checks code against the handbook’s rules in real time, helping maintain quality and efficiency.

When a rule is violated, the plugin highlights the issue and offers one‑click detection of all violations.

Alibaba Cloud Toolkit

Open View → Tool Windows → Statistic to see metrics such as total Java code size (e.g., 2818 kB) and line count (e.g., 85 645 lines).

Vue.js

The Vue.js plugin adds support for .vue files and provides intelligent code completion for Vue directives.

After enabling the plugin, you can create .vue files from templates and receive suggestions for attributes starting with
