Mybatis-generator-meven-plugin

1. Configure mybatis-generator-Maven-plugin in POM. xml

<build>    <plugins>        <!-- mybatis-generator -->            <plugin>                      <groupId>org.mybatis.generator</groupId>                      <artifactId>mybatis-generator-maven-plugin</artifactId>                      <version>1.3.1</version>                      <configuration>                          <verbose>true</verbose>                          <overwrite>true</overwrite>                      </configuration>              </plugin>    </plugins></build> 

2. generatorconfig. XML, which is placed under src/main/resource. You need to set ① database driver path, ② JDBC connection information, ③ package name and storage path of entity, XML, and Dao files (if it is set to a non-project path, copy it to the corresponding path under the project after generation), ④ name of the table to be generated (entity).
