MyBatis-Plus Quick Start: Environment Setup and Common Error Troubleshooting

MyBatis-Plus (MP) is an enhancement tool for MyBatis that simplifies development and improves efficiency.

1. Environment Setup

1.1 Configure pom.xml

1.1.1 Add MyBatis‑Plus generator dependency

<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>mybatis-plus-generator</artifactId>
    <version>3.3.0</version>
</dependency>

1.1.2 Add MySQL connector dependency

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
</dependency>

1.1.3 Install Lombok plugin

Install the Lombok plugin in the IDE (Setting → Plugins → Lombok) to avoid writing getter and setter methods manually.

2. Common Error Summary

1. IDEA run Spring Boot error: cannot find org.springframework.context.ConfigurableApplicationContext

Solution: execute mvn package to build the project.

2. Various dependencies not found

Solution: run mvn clean and then rebuild; note that downloading dependencies may take a long time (over 12 hours in some cases).
