## 一、导入坐标依赖 ##

<dependency>
                <groupId>com.baomidou</groupId>
                <artifactId>mybatis-plus-boot-starter</artifactId>
                <version>3.3.2</version>
            </dependency>
            <dependency>
                <groupId>mysql</groupId>
                <artifactId>mysql-connector-java</artifactId>
                <version>5.1.17</version>
            </dependency>
            
            
            <dependency>
                <groupId>org.apache.velocity</groupId>
                <artifactId>velocity-engine-core</artifactId>
                <version>2.2</version>
            </dependency>
            
            <dependency>
                <groupId>com.baomidou</groupId>
                <artifactId>mybatis-plus-generator</artifactId>
                <version>3.3.2</version>
            </dependency>

## 二、编写自动生成工具类’ ##

package com.tclp.util;
    
    
    import com.baomidou.mybatisplus.generator.AutoGenerator;
    import com.baomidou.mybatisplus.generator.config.*;
    import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;
    
    public class MybatisPlusUtil {
        public static void main(String[] args) {
    
            String userDir = System.getProperty("user.dir");
            System.out.println("userDir=" + userDir);
    
            // 代码生成器
            AutoGenerator mpg = new AutoGenerator();
    
            // 全局配置
            GlobalConfig gc = new GlobalConfig();
            //获取当前的项目的路径
            String projectPath = System.getProperty("user.dir");
            System.out.println(projectPath);
            //配置生成路径
            gc.setOutputDir(projectPath + "/src/main/java");
            // 作者名称
            gc.setAuthor("rock");
            gc.setBaseResultMap(true);
            gc.setBaseColumnList(true);
            mpg.setGlobalConfig(gc);
    
    
            // 数据源配置
            DataSourceConfig dsc = new DataSourceConfig();
            dsc.setUrl("jdbc:mysql://localhost:3306/java220401?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull");
            dsc.setDriverName("com.mysql.jdbc.Driver");
            dsc.setUsername("root");
            dsc.setPassword("1234");
            mpg.setDataSource(dsc);
    
            // 包配置
            PackageConfig pc = new PackageConfig();
            pc.setParent("com.hqyj");
            pc.setController("controller");
            pc.setEntity("pojo");
            pc.setMapper("dao");
    
            mpg.setPackageInfo(pc);
    
            // 配置模板
            TemplateConfig templateConfig = new TemplateConfig();
            //templateConfig.setXml(null);
            templateConfig.setXml("/templates/mapper.xml");
            mpg.setTemplate(templateConfig);
    
            // 策略配置
            StrategyConfig strategy = new StrategyConfig();
            strategy.setNaming(NamingStrategy.underline_to_camel);
            strategy.setColumnNaming(NamingStrategy.underline_to_camel);
            strategy.setEntityLombokModel(true);
            strategy.setRestControllerStyle(true);
            strategy.setInclude("power");//表名
            strategy.setControllerMappingHyphenStyle(true);
            strategy.setTablePrefix(pc.getModuleName() + "_");
            mpg.setStrategy(strategy);
            //mpg.setTemplateEngine(new FreemarkerTemplateEngine());
            mpg.execute();
        }
    
    }
