前期準備：

MYSQL數據庫表

CREATE TABLE `tbl_employee` (`id` int(11) NOT NULL AUTO_INCREMENT,`last_name` varchar(50) COLLATE utf8_bin DEFAULT NULL,`email` varchar(50) COLLATE utf8_bin DEFAULT NULL,`gender` char(1) COLLATE utf8_bin DEFAULT NULL,`age` int(11) DEFAULT NULL,PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8 COLLATE=utf8_bin;

測試數據

INSERT INTO tbl_employee(last_name,email,gender,age) VALUES('Tom','tom@atguigu.com',1,22); INSERT INTO tbl_employee(last_name,email,gender,age) VALUES('Jerry','jerry@atguigu.com',0,25); INSERT INTO tbl_employee(last_name,email,gender,age) VALUES('Black','black@atguigu.com',1,30); INSERT INTO tbl_employee(last_name,email,gender,age) VALUES('White','white@atguigu.com',0,35)

user

CREATE TABLE `user` (`id` bigint(20) NOT NULL COMMENT '主鍵ID',`name` varchar(30) COLLATE utf8_bin DEFAULT NULL COMMENT '姓名',`age` int(11) DEFAULT NULL COMMENT '年齡',`email` varchar(50) COLLATE utf8_bin DEFAULT NULL COMMENT '郵箱',PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin;

測試數據

DELETE FROM user;INSERT INTO user (id, name, age, email) VALUES (1, 'Jone', 18, 'test1@baomidou.com'), (2, 'Jack', 20, 'test2@baomidou.com'), (3, 'Tom', 28, 'test3@baomidou.com'), (4, 'Sandy', 21, 'test4@baomidou.com'), (5, 'Billie', 24, 'test5@baomidou.com');

看圖操作，一路下一步

搭建SpringBoot基礎環境完成！！！

1. 導入相關依賴

2. 新建代碼生成類MysqlGenerator

2.1. MYSQL 代碼生成部分

2.2. ORACLE代碼生成部分

package com.gblfy.mybatisplus.generator;import com.baomidou.mybatisplus.annotation.DbType; import com.baomidou.mybatisplus.annotation.IdType; 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;/*** * mysql 代碼生成器演示例子* ** @author gblfy* @since 2019-07-12*/ public class MysqlGenerator {/*************************************ORACLE代碼生成 Start *************************************/// 全局配置private final static String OUTPUT_XML_DIR = "/src/main/resources";// 生成xml文件的輸出目錄private final static String AUTHOR = "gblfy";// 開發人員// 數據源配置private final static String ORACLE_DRIVER_NAME = "oracle.jdbc.driver.OracleDriver";// ORACLE數據庫驅動private final static String DATABASE_IP = "xx.x.x.x";// 數據庫ipprivate final static String ORACLE_DATABASE_NAME = "h";// 數據庫名稱private final static String ORACLE_DB_USERNAME = "root";// 數據庫用戶private final static String ORACLE_DB_PASSWORD = "root";// 數據庫口令private final static String ORACLE_DB_PORT = "1521";// ORACLE數據庫端口// 包和數據庫表配置private final static String MODULE_NAME = "acc";// 父包模塊名private final static String PARENT_PACKAGE = "com.gblfy.mybatisplus.generator";// 父包名。如果為空，將下面子包名必須寫全部，否則就只需寫子包名private final static String[] TABLE_NAME_LIST = {"USER"};// 父包模塊名// 自定義基類private final static String SuperEntity = PARENT_PACKAGE + ".common.BaseEntity";private final static String SuperController = PARENT_PACKAGE + ".common.BaseController";/*** 運行main方法即可* 1.全局配置* 2.數據源配置* 3.包配置策略* 4.策略配置* 5.整合配置*/public static void main(String[] args) {//獲取項目本地磁盤路徑String projectPath = System.getProperty("user.dir"); /********************************** 全局配置**********************************/// 全局配置GlobalConfig gc = new GlobalConfig();//生成java文件的存放位置gc.setOutputDir(projectPath + "/src/main/java").setAuthor(AUTHOR)//作者署名.setFileOverride(true)//是否文件覆蓋.setIdType(IdType.ID_WORKER)//主鍵策略.setBaseResultMap(true).setBaseColumnList(true)//生成sql片段//.setServiceName("%sService")//設置生成service接口是否首字母是I//是否打開輸出目錄.setOpen(false); /********************************** 數據源配置**********************************/DataSourceConfig dsc = new DataSourceConfig();dsc.setDbType(DbType.ORACLE)//設置數據庫類型.setUrl("jdbc:oracle:thin:@" + DATABASE_IP + ":" + ORACLE_DB_PORT + ":" + ORACLE_DATABASE_NAME).setDriverName(ORACLE_DRIVER_NAME).setUsername(ORACLE_DB_USERNAME).setPassword(ORACLE_DB_PASSWORD); /********************************** 包名配置**********************************/// 包配置PackageConfig pc = new PackageConfig();pc.setParent(PARENT_PACKAGE).setModuleName(MODULE_NAME).setController("controller").setService("service").setServiceImpl("service.impl").setMapper("mapper");// 自定義配置InjectionConfig cfg = new InjectionConfig() {@Overridepublic void initMap() {// to do nothing}};List<FileOutConfig> focList = new ArrayList<>();focList.add(new FileOutConfig("/templates/mapper.xml.ftl") {@Overridepublic String outputFile(TableInfo tableInfo) {// 自定義輸入文件名稱單模塊場景return projectPath + OUTPUT_XML_DIR + "/mapper/" + pc.getModuleName()+ "/" + tableInfo.getEntityName() + "Mapper" + StringPool.DOT_XML;}});cfg.setFileOutConfigList(focList); /********************************** 策略配置**********************************/// 策略配置StrategyConfig strategy = new StrategyConfig();strategy.setCapitalMode(true)//全局大小寫命名.setColumnNaming(NamingStrategy.underline_to_camel)//數據庫字段是否下劃線轉駝峰.setNaming(NamingStrategy.underline_to_camel)//數據庫表映射到實體的命名策略.setSuperEntityClass(SuperEntity).setEntityLombokModel(true).setSuperControllerClass(SuperController).setInclude(TABLE_NAME_LIST).setSuperEntityColumns("id").setControllerMappingHyphenStyle(true).setTablePrefix(pc.getModuleName() + "_");// 配置整合代碼生成器AutoGenerator mpg = new AutoGenerator();//配置信息添加至全局配置容器mpg.setGlobalConfig(gc).setStrategy(strategy).setDataSource(dsc).setPackageInfo(pc).setCfg(cfg).setTemplate(new TemplateConfig().setXml(null)).setTemplateEngine(new FreemarkerTemplateEngine())// 選擇 freemarker 引擎需要指定如下加，注意 pom 依賴必須有！.execute();//執行}/*************************************MYSQL代碼生成 End *************************************/}

3. 創建全局配置文件

# Mysql數據庫 spring:datasource:driver-class-name: com.mysql.cj.jdbc.Driverurl: jdbc:mysql://127.0.0.1:3306/mp?autoReconnect=true&useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=CONVERT_TO_NULL&useSSL=false&serverTimezone=CTTusername: rootpassword: root# Logger Config logging:level:com.gblfy.mybatisplus.generator: debug

4. 啟動類加@MapperScan注解

package com.gblfy.mybatisplus.generator;import org.mybatis.spring.annotation.MapperScan; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication @MapperScan("com.gblfy.mybatisplus.generator.emp.mapper") public class MybatisPlusGeneratorApplication {public static void main(String[] args) {SpringApplication.run(MybatisPlusGeneratorApplication.class, args);} }

5. 在controller層寫個測試方法：

package com.gblfy.mybatisplus.generator.emp.controller;import com.gblfy.mybatisplus.generator.common.BaseController; import com.gblfy.mybatisplus.generator.emp.entity.TblEmployee; import com.gblfy.mybatisplus.generator.emp.service.ITblEmployeeService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody;import java.util.List;/*** * 前端控制器* ** @author gblfy* @since 2019-07-13*/ @Controller @RequestMapping("/emp/tbl-employee") public class TblEmployeeController extends BaseController {@Autowiredprivate ITblEmployeeService employeeService;@RequestMapping("")@ResponseBodypublic List<TblEmployee> list() {List<TblEmployee> list = employeeService.list();return list;} }

6. 瀏覽器驗證

http://localhost:8080/emp/tbl-employee

7. 多模塊適配Mybatisplus代碼生成之SpringBoot適配MYSQL和ORACLE

多模塊適配只是目錄有所他調整而已

package com.baomidou.mybatisplus.samples.generator;import com.baomidou.mybatisplus.core.exceptions.MybatisPlusException; import com.baomidou.mybatisplus.core.toolkit.StringPool; import com.baomidou.mybatisplus.core.toolkit.StringUtils; 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.Scanner;/*** * mysql 代碼生成器演示例子* ** @author jobob* @since 2018-09-12*/ public class MysqlGenerator {// 全局配置private final static String PROJECT_DIR = "/mybatis-plus-sample-generator";// 項目名稱private final static String OUTPUT_JAVA_DIR = PROJECT_DIR + "/src/main/java";// 生成java文件的輸出目錄private final static String OUTPUT_XML_DIR = PROJECT_DIR + "/src/main/resources";// 生成xml文件的輸出目錄private final static String AUTHOR = "gblfy";// 開發人員// 數據源配置private final static String DRIVER_NAME = "com.mysql.cj.jdbc.Driver";// 數據庫驅動private final static String DATABASE_IP = "localhost";// 數據庫ipprivate final static String DATABASE_NAME = "mp";// 數據庫名稱private final static String DB_USERNAME = "root";// 數據庫用戶private final static String DB_PASSWORD = "root";// 數據庫口令// 包配置private final static String PARENT_PACKAGE = "com.baomidou.mybatisplus.samples.generator";// 父包名。如果為空，將下面子包名必須寫全部，否則就只需寫子包名private final static String MODULE_NAME = "empl";// 父包模塊名private final static String[] TABLE_NAME_LIST = {"tbl_employee", "user"};// 父包模塊名// 自定義基類private final static String SuperEntity = PARENT_PACKAGE + ".common.BaseEntity";private final static String SuperController = PARENT_PACKAGE + ".common.BaseController";/*** * 讀取控制臺內容* */public static String scanner(String tip) {Scanner scanner = new Scanner(System.in);StringBuilder help = new StringBuilder();help.append("請輸入" + tip + "：");System.out.println(help.toString());if (scanner.hasNext()) {String ipt = scanner.next();if (StringUtils.isNotEmpty(ipt)) {return ipt;}}throw new MybatisPlusException("請輸入正確的" + tip + "！");}/*** RUN THIS*/public static void main(String[] args) {// 代碼生成器AutoGenerator mpg = new AutoGenerator();// 全局配置GlobalConfig gc = new GlobalConfig();String projectPath = System.getProperty("user.dir");System.out.println("projectPath" + projectPath);/***projectPath 代表父工程的本地磁盤位置* /mybatis-plus-sample-generator ：子項目位置* 多模塊場景* 格式：projectPath+子項目位置** 單模塊* 格式：projectPath*/gc.setOutputDir(projectPath + OUTPUT_JAVA_DIR);gc.setAuthor(AUTHOR);gc.setOpen(false);mpg.setGlobalConfig(gc);// 數據源配置DataSourceConfig dsc = new DataSourceConfig();dsc.setUrl("jdbc:mysql://" + DATABASE_IP + ":3306/" + DATABASE_NAME + "?useUnicode=true&useSSL=false&characterEncoding=utf8");dsc.setDriverName(DRIVER_NAME);dsc.setUsername(DB_USERNAME);dsc.setPassword(DB_PASSWORD);mpg.setDataSource(dsc);// 包配置PackageConfig pc = new PackageConfig(); // pc.setModuleName(scanner("模塊名"));pc.setModuleName(MODULE_NAME);pc.setParent(PARENT_PACKAGE);mpg.setPackageInfo(pc);// 自定義配置InjectionConfig cfg = new InjectionConfig() {@Overridepublic void initMap() {// to do nothing}};List<FileOutConfig> focList = new ArrayList<>();focList.add(new FileOutConfig("/templates/mapper.xml.ftl") {@Overridepublic String outputFile(TableInfo tableInfo) {// 自定義輸入文件名稱return projectPath + OUTPUT_XML_DIR + "/mapper/" + pc.getModuleName()+ "/" + tableInfo.getEntityName() + "Mapper" + 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.setSuperEntityClass(SuperEntity);strategy.setEntityLombokModel(true);strategy.setSuperControllerClass(SuperController); // strategy.setInclude(new String[]{"tbl_employee", "user"});strategy.setInclude(TABLE_NAME_LIST);strategy.setSuperEntityColumns("id");strategy.setControllerMappingHyphenStyle(true);strategy.setTablePrefix(pc.getModuleName() + "_");mpg.setStrategy(strategy);// 選擇 freemarker 引擎需要指定如下加，注意 pom 依賴必須有！mpg.setTemplateEngine(new FreemarkerTemplateEngine());mpg.execute();}}
