MybatisPlus自动生成代码配置

1、向pom文件添加依赖mybatisplus相关依赖

 <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>

        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.4.1</version>
        </dependency>
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-generator</artifactId>
            <version>3.4.1</version>
        </dependency>

        <!--模板引擎反向生成代码用-->
        <dependency>
            <groupId>org.freemarker</groupId>
            <artifactId>freemarker</artifactId>
            <version>2.3.30</version>
        </dependency>
        <dependency>
            <groupId>org.apache.velocity</groupId>
            <artifactId>velocity-engine-core</artifactId>
            <version>2.2</version>
        </dependency>
        <dependency>
            <groupId>com.ibeetl</groupId>
            <artifactId>beetl</artifactId>
            <version>3.2.3.RELEASE</version>
        </dependency>

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

2、配置mybatis-plus.properties文件

#此处为本项目src所在路径（代码生成器输出路径）
OutputDir=E:/liangd/springboot/springboot-mp-generator/src/main/java
#mapper.xml的生成位置
OutputDirXml=E:/liangd/springboot/springboot-mp-generator/src/main/resources
#数据库表名(此处切不可为空，如果为空，则默认读取数据库的所有表名),也可在config文件中指定
#tableName=sys_user,sys_role,sys_permission
#设置作者
author=liangd
#自定义包路径
parent=com.donleo.mp.generator
#数据库地址与yml配置的数据源地址一致
url=jdbc:mysql://localhost:3306/spring_security?useUnicode=true&characterEncoding=utf-8&serverTimezone=Asia/Shanghai
userName=root
password=123456
driver=com.mysql.cj.jdbc.Driver

3、编写CodeGenerator工具类

package com.donleo.mp.generator.config;

import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.core.toolkit.StringPool;
import com.baomidou.mybatisplus.generator.AutoGenerator;
import com.baomidou.mybatisplus.generator.InjectionConfig;
import com.baomidou.mybatisplus.generator.config.*;
import com.baomidou.mybatisplus.generator.config.po.TableInfo;
import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;
import com.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine;

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

/**
 * @author liangd

 * code mybatisplus代码生成器配置
 * 生成完毕最好注释或删除此文件
 */
public class CodeGenerator {
    public static void main(String[] args) throws InterruptedException {

        //用来获取Mybatis-Plus.properties文件的配置信息
        final ResourceBundle rb = ResourceBundle.getBundle("mybatis-plus");

        // 代码生成器
        AutoGenerator mpg = new AutoGenerator();

        // 全局配置
        GlobalConfig gc = new GlobalConfig();
        gc.setOutputDir(rb.getString("OutputDir"));
        gc.setOpen(false);
        gc.setBaseResultMap(true);
        gc.setBaseColumnList(true);
        gc.setAuthor(rb.getString("author"));
        gc.setMapperName("%sMapper");
        gc.setXmlName("%sMapper");
        gc.setServiceName("%sService");
        gc.setServiceImplName("%sServiceImpl");
        gc.setControllerName("%sController");
        mpg.setGlobalConfig(gc);

        // 数据源配置
        DataSourceConfig dsc = new DataSourceConfig();
        dsc.setDbType(DbType.MYSQL);
        dsc.setUrl(rb.getString("url"));
        dsc.setDriverName(rb.getString("driver"));
        dsc.setUsername(rb.getString("userName"));
        dsc.setPassword(rb.getString("password"));
        mpg.setDataSource(dsc);

        // 包配置
        PackageConfig pc = new PackageConfig();
        pc.setParent(rb.getString("parent"));
        pc.setController("controller");
        pc.setService("service");
        pc.setServiceImpl("service.impl");
        pc.setEntity("model");
        pc.setMapper("mapper");
        mpg.setPackageInfo(pc);

        // 自定义配置
        InjectionConfig cfg = new InjectionConfig() {
            @Override
            public void initMap() {
                // to do nothing
            }
        };
        List<FileOutConfig> focList = new ArrayList<>();
        focList.add(new FileOutConfig("/templates/mapper.xml.ftl") {
            @Override
            public String outputFile(TableInfo tableInfo) {
                // 自定义输入文件名称
                return rb.getString("OutputDirXml") + "/mapper/" + tableInfo.getEntityName() + StringPool.DOT_XML;
            }
        });
        cfg.setFileOutConfigList(focList);
        mpg.setCfg(cfg);
        mpg.setTemplate(new TemplateConfig().setXml(null));

        // 策略配置
        StrategyConfig strategy = new StrategyConfig();
        strategy.setNaming(NamingStrategy.underline_to_camel);
        strategy.setColumnNaming(NamingStrategy.underline_to_camel);
        strategy.setEntityLombokModel(true);
        strategy.setInclude("sys_user", "sys_role", "sys_permission", "sys_role_permission_relation", "sys_user_permission_relation", "sys_user_role_relation");
        strategy.setTablePrefix("sys_");
        mpg.setStrategy(strategy);
        mpg.setTemplateEngine(new FreemarkerTemplateEngine());
        mpg.execute();
    }
}
