篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了使用mybatis-plus-generator进行代码自动生成相关的知识，希望对你有一定的参考价值。
为了解放程序员的双手，减少重复性代码的编写，推荐使用插件：mybatis-plus-generator 进行代码自动生成。下面我将详细介绍通过 mybatis-plus-generator 插件自动生成 controller、service、mapper、serviceImpl相关代码。
项目工程目录总览如下：
1. 使用 idea 创建 maven 项目，引入相关依赖，项目pom文件如下所示：
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.miaoying.generator</groupId> <artifactId>generator-demo</artifactId> <version>1.0-SNAPSHOT</version> <properties> <mybatis-plus.version>3.0.1</mybatis-plus.version> <mysql.connector.java.version>8.0.19</mysql.connector.java.version> <springfox-swagger.version>2.9.2</springfox-swagger.version> </properties> <dependencies> <!-- mybatisPlus 核心库 --> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-boot-starter</artifactId> <version>${mybatis-plus.version}</version> </dependency> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-generator</artifactId> <version>${mybatis-plus.version}</version> </dependency> <!-- 提供mysql驱动 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>${mysql.connector.java.version}</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <version>RELEASE</version> <scope>compile</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <version>RELEASE</version> <scope>compile</scope> </dependency> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger-ui</artifactId> <version>${springfox-swagger.version}</version> </dependency> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger2</artifactId> <version>${springfox-swagger.version}</version> </dependency> </dependencies> </project>

4. 执行 CodeGenerator.java 里面的 main 方法，根据个人数据库表的配置与期望的工程目录的配置，依次输入模块名、表名、表前缀，比如我的数据库里面有张表叫做： header_click，执行 main 方法时，根据提示依次输入如下：header、header_click、#，最终会在项目工程目录里新增对应的自动生成的文件：
执行 main 方法时，控制台的日志输出如下：
