我用的是vm模板，你用mybatisplus3.5.1帮我写一个代码生成器 ，

好的，首先需要在pom.xml中添加MyBatis Plus的依赖：

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

然后，在src/main/java下创建com.example.codegenerator包，在该包下创建CodeGenerator类，用于生成代码：

package com.example.codegenerator;

import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.generator.AutoGenerator;
import com.baomidou.mybatisplus.generator.config.*;
import com.baomidou.mybatisplus.generator.config.builder.ConfigBuilder;
import com.baomidou.mybatisplus.generator.config.po.TableFill;
import com.baomidou.mybatisplus.generator.config.po.TableInfo;
import com.baomidou.mybatisplus.generator.config.rules.DateType;
import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;

import java.util.ArrayList;
import java.util.List;

public class CodeGenerator {

    public static void main(String[] args) {
        // 代码生成器
        AutoGenerator mpg = new AutoGenerator();

        // 全局配置
        GlobalConfig gc = new GlobalConfig();
        String projectPath = System.getProperty("user.dir");
        gc.setOutputDir(projectPath + "/src/main/java");
        gc.setAuthor("Your Name");
        gc.setOpen(false);
        gc.setFileOverride(false);
        gc.setServiceName("%sService");
        gc.setIdType(IdType.AUTO);
        gc.setDateType(DateType.ONLY_DATE);
        gc.setSwagger2(true);
        mpg.setGlobalConfig(gc);

        // 数据源配置
        DataSourceConfig dsc = new DataSourceConfig();
        dsc.setUrl("jdbc:mysql://localhost:3306/mybatis_plus?useUnicode=true&characterEncoding=utf-8&serverTimezone=GMT%2B8");
        dsc.setDriverName("com.mysql.cj.jdbc.Driver");
        dsc.setUsername("root");
        dsc.setPassword("password");
        dsc.setDbType(DbType.MYSQL);
        mpg.setDataSource(dsc);

        // 包配置
        PackageConfig pc = new PackageConfig();
        pc.setParent("com.example");
        pc.setEntity("entity");
        pc.setMapper("mapper");
        pc.setService("service");
        pc.setServiceImpl("service.impl");
        pc.setController("controller");
        mpg.setPackageInfo(pc);

        // 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.setChainModel(true);
        strategy.setLogicDeleteFieldName("deleted");
        strategy.setEntityBooleanColumnRemoveIsPrefix(true);
        strategy.setVersionFieldName("version");
        strategy.setTableFillList(getTableFillList());
        strategy.setSuperEntityClass("com.baomidou.mybatisplus.extension.activerecord.Model");
        strategy.setSuperEntityColumns("id", "create_time", "update_time", "version");
        strategy.setSuperServiceClass("com.baomidou.mybatisplus.extension.service.IService");
        strategy.setSuperServiceImplClass("com.baomidou.mybatisplus.extension.service.impl.ServiceImpl");
        strategy.setSuperMapperClass("com.baomidou.mybatisplus.core.mapper.BaseMapper");
        strategy.setInclude("user");
        mpg.setStrategy(strategy);

        // 把配置全部注入到ConfigBuilder中
        ConfigBuilder configBuilder = new ConfigBuilder(pc, dsc, strategy, new TemplateConfig(), gc);
        // 获取所有表的信息
        List<TableInfo> tableInfoList = configBuilder.getTableInfoList();
        // 循环生成代码
        for (TableInfo tableInfo : tableInfoList) {
            mpg.execute(new InjectionConfig() {
                @Override
                public void initMap() {
                    // to do nothing
                }
            }.setFileOutConfigList(getFileOutConfigList(tableInfo, pc.getModuleName())));
        }
    }

    private static List<TableFill> getTableFillList() {
        List<TableFill> tableFillList = new ArrayList<>();
        tableFillList.add(new TableFill("create_time", FieldFill.INSERT));
        tableFillList.add(new TableFill("update_time", FieldFill.INSERT_UPDATE));
        return tableFillList;
    }

    private static List<FileOutConfig> getFileOutConfigList(TableInfo tableInfo, String moduleName) {
        List<FileOutConfig> fileOutConfigList = new ArrayList<>();
        String entityName = tableInfo.getEntityName();
        String packageName = "com.example." + moduleName;
        String entityPath = "/src/main/java/" + packageName.replaceAll("\\.", "/") + "/entity/" + entityName + ".java";
        String mapperPath = "/src/main/java/" + packageName.replaceAll("\\.", "/") + "/mapper/" + entityName + "Mapper.java";
        String xmlPath = "/src/main/resources/mapper/" + entityName + "Mapper.xml";
        String servicePath = "/src/main/java/" + packageName.replaceAll("\\.", "/") + "/service/I" + entityName + "Service.java";
        String serviceImplPath = "/src/main/java/" + packageName.replaceAll("\\.", "/") + "/service/impl/" + entityName + "ServiceImpl.java";
        String controllerPath = "/src/main/java/" + packageName.replaceAll("\\.", "/") + "/controller/" + entityName + "Controller.java";

        fileOutConfigList.add(new FileOutConfig("/templates/entity.java.ftl") {
            @Override
            public String outputFile(TableInfo tableInfo) {
                return System.getProperty("user.dir") + entityPath;
            }
        });

        fileOutConfigList.add(new FileOutConfig("/templates/mapper.java.ftl") {
            @Override
            public String outputFile(TableInfo tableInfo) {
                return System.getProperty("user.dir") + mapperPath;
            }
        });

        fileOutConfigList.add(new FileOutConfig("/templates/mapper.xml.ftl") {
            @Override
            public String outputFile(TableInfo tableInfo) {
                return System.getProperty("user.dir") + xmlPath;
            }
        });

        fileOutConfigList.add(new FileOutConfig("/templates/service.java.ftl") {
            @Override
            public String outputFile(TableInfo tableInfo) {
                return System.getProperty("user.dir") + servicePath;
            }
        });

        fileOutConfigList.add(new FileOutConfig("/templates/serviceImpl.java.ftl") {
            @Override
            public String outputFile(TableInfo tableInfo) {
                return System.getProperty("user.dir") + serviceImplPath;
            }
        });

        fileOutConfigList.add(new FileOutConfig("/templates/controller.java.ftl") {
            @Override
            public String outputFile(TableInfo tableInfo) {
                return System.getProperty("user.dir") + controllerPath;
            }
        });
        return fileOutConfigList;
    }
}

在resources目录下创建/templates/entity.java.ftl、/templates/mapper.java.ftl、/templates/mapper.xml.ftl、/templates/service.java.ftl、/templates/serviceImpl.java.ftl、/templates/controller.java.ftl这六个模板文件，用于生成代码。

最后运行CodeGenerator类即可生成代码。
