Using MybatisX Plugin for Rapid MyBatis Development in Spring Boot

MybatisX is an IntelliJ IDEA plugin that streamlines MyBatis and MyBatis‑Plus development by automating repetitive tasks and accelerating coding speed.

Key benefits include massive time savings on persistence layer code, powerful features that support business development, and simple configuration that eliminates complex XML files.

The tutorial walks through the following steps:

Create a simple MySQL database.

Initialize a Spring Boot project.

Add the MyBatis‑Plus starter dependency to

<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>mybatis-plus-boot-starter</artifactId>
    <version>3.5.1</version>
</dependency>

in pom.xml.

Install MybatisX via File → Settings → Plugins → Marketplace → MybatisX.

Configure the database connection in the IDE, set the server timezone to GMT to resolve connection errors, and test the connection.

Use the MybatisX generator to create entity classes, mapper interfaces, service classes, and related files.

Example application.yaml configuration:

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/user?characterEncoding=utf-8&useSSL=false&serverTimezone=GMT
    username: root
    password: password

Sample controller using MyBatis‑Plus QueryWrapper:

package com.example.mybatixtest.controller;

import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.example.mybatixtest.pojo.User;
import com.example.mybatixtest.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class TestController {
    @Autowired
    UserService userService;

    @GetMapping("/test")
    public User test(){
        QueryWrapper<User> userQueryWrapper = new QueryWrapper<>();
        userQueryWrapper.eq("user_id",1);
        User user = userService.getOne(userQueryWrapper);
        return user;
    }
}

After running the application, the /test endpoint returns the expected user data, confirming that MybatisX integration with Spring Boot is complete.
