Generate Spring Boot CRUD Code Instantly with EasyCode Plugin

Overview

EasyCode is an IntelliJ IDEA plugin that generates Java code (entity, mapper, service, controller, etc.) from database tables using customizable templates. It maps database types to Java types and supports batch generation for multiple tables.

Prerequisites

IntelliJ IDEA (Community or Ultimate)

EasyCode plugin installed via Settings → Plugins → Marketplace

Lombok plugin (optional but recommended for reducing boilerplate)

Java 8+ and Maven

Database preparation

Create a MySQL database and the required tables. Example:

-- Table structure for user
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
  `id` int(11) NOT NULL,
  `username` varchar(20) DEFAULT NULL,
  `sex` varchar(6) DEFAULT NULL,
  `birthday` date DEFAULT NULL,
  `address` varchar(20) DEFAULT NULL,
  `password` varchar(20) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
SET FOREIGN_KEY_CHECKS = 1;

Configure database connection in IDEA

In the Database tool window, add a new MySQL data source, fill in the URL, username, and password, and test the connection.

Generate code with EasyCode

Open the Spring Boot project in IDEA.

In the Database view, locate the target table, right‑click → EasyCode → Generate .

Select the output directory.

Check the components to generate (Entity, Mapper, Service, Controller, etc.).

Confirm – EasyCode creates the source files under the chosen package.

Maven dependencies

Add the following dependencies to pom.xml (adjust versions as needed):

server:
  port: 8089

spring:
  datasource:
    url: jdbc:mysql://127.0.0.1:3306/database?useUnicode=true&characterEncoding=UTF-8
    username: root
    password: 123456

    type: com.alibaba.druid.pool.DruidDataSource

mybatis:
  mapper-locations: classpath:/mapper/*Dao.xml
  typeAliasesPackage: com.vue.demo.entity

Enable MyBatis mapper scanning

Add @Mapper on each DAO interface and @MapperScan("com.vue.demo.dao") on the main Spring Boot application class.

Run the application

Execute mvn spring-boot:run or run the main method from the IDE. Verify that the generated REST endpoints are reachable (e.g., http://localhost:8089/user/list).
