首先创建springboot的项目，创建步骤省略；
创建好项目后要配置maven依赖，附上pom.xml；
<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.2.1.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.niuben.springboot</groupId> <artifactId>demo1</artifactId> <version>0.0.1-SNAPSHOT</version> <name>demo1</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>2.0.1</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <scope>runtime</scope> </dependency> <dependency> <groupId>com.sdsvs.finsvc</groupId> <artifactId>mysql-connector</artifactId> <version>1.1</version> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency> <!-- 这是mybatis-plus依赖 --> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-boot-starter</artifactId> <version>3.1.1</version> </dependency> <!-- 这是mybatis-plus的代码自动生成器 --> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-generator</artifactId> <version>3.1.1</version> </dependency> <!-- 这是模板引擎依赖 --> <dependency> <groupId>org.freemarker</groupId> <artifactId>freemarker</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
配置mybatis-plus的代码生成器CodeGenerator.class；
@SpringBootTest public class GeneratorTest { /** * <p> * 读取控制台内容 * </p> */ public static String scanner(String tip) { Scanner scanner = new Scanner(System.in); StringBuilder help = new StringBuilder(); help.append("请输入" + tip + "："); System.out.println(help.toString()); if (scanner.hasNext()) { String ipt = scanner.next(); if (StringUtils.isNotEmpty(ipt)) { return ipt; } } throw new MybatisPlusException("请输入正确的" + tip + "！"); } public static void main(String[] args) { // 代码生成器 AutoGenerator mpg = new AutoGenerator(); // 全局配置 GlobalConfig gc = new GlobalConfig(); //获取当前文件路径 //String projectPath = "D:\IntelliJ IDEA workspace\test-study\demo2"; //多模块时建议自定义路径 String projectPath = System.getProperty("user.dir"); System.out.println(projectPath); gc.setOutputDir(projectPath + "/src/main/java"); gc.setAuthor("作者姓名"); gc.setOpen(false); // gc.setSwagger2(true); 实体属性 Swagger2 注解 mpg.setGlobalConfig(gc); // 数据源配置 DataSourceConfig dsc = new DataSourceConfig(); dsc.setUrl("jdbc:mysql://localhost:3306/user?characterEncoding=utf8"); // dsc.setSchemaName("public"); dsc.setDriverName("com.mysql.cj.jdbc.Driver"); dsc.setUsername("root"); dsc.setPassword("密码"); mpg.setDataSource(dsc); // 包配置 PackageConfig pc = new PackageConfig(); pc.setModuleName(scanner("模块名")); //生成代码所在包 pc.setParent("com.xxx.xxx"); mpg.setPackageInfo(pc); // 自定义配置 InjectionConfig cfg = new InjectionConfig() { @Override public void initMap() { // to do nothing } }; // 如果模板引擎是 freemarker String templatePath = "/templates/mapper.xml.ftl"; // 如果模板引擎是 velocity // String templatePath = "/templates/mapper.xml.vm"; // 自定义输出配置 List<FileOutConfig> focList = new ArrayList<>(); // 自定义配置会被优先输出 focList.add(new FileOutConfig(templatePath) { @Override public String outputFile(TableInfo tableInfo) { // 自定义输出文件名 ， 如果你 Entity 设置了前后缀、此处注意 xml 的名称会跟着发生变化！！ return projectPath + "/src/main/resources/mapper/" + pc.getModuleName() + "/" + tableInfo.getEntityName() + "Mapper" + StringPool.DOT_XML; } }); /* cfg.setFileCreate(new IFileCreate() { @Override public boolean isCreate(ConfigBuilder configBuilder, FileType fileType, String filePath) { // 判断自定义文件夹是否需要创建 checkDir("调用默认方法创建的目录"); return false; } }); */ cfg.setFileOutConfigList(focList); mpg.setCfg(cfg); // 配置模板 TemplateConfig templateConfig = new TemplateConfig(); // 配置自定义输出模板 //指定自定义模板路径，注意不要带上.ftl/.vm, 会根据使用的模板引擎自动识别 // templateConfig.setEntity("templates/entity2.java"); // templateConfig.setService(); // templateConfig.setController(); templateConfig.setXml(null); mpg.setTemplate(templateConfig); // 策略配置 StrategyConfig strategy = new StrategyConfig(); strategy.setNaming(NamingStrategy.underline_to_camel); strategy.setColumnNaming(NamingStrategy.underline_to_camel); //strategy.setSuperEntityClass("com.xxx.springboot.common.BaseEntity"); strategy.setEntityLombokModel(true); strategy.setRestControllerStyle(true); // 公共父类 //strategy.setSuperControllerClass("com.xxx.springboot.common.BaseController"); // 写于父类中的公共字段 strategy.setSuperEntityColumns("id"); strategy.setInclude(scanner("表名，多个英文逗号分割").split(",")); strategy.setControllerMappingHyphenStyle(true); strategy.setTablePrefix(pc.getModuleName() + "_"); mpg.setStrategy(strategy); mpg.setTemplateEngine(new FreemarkerTemplateEngine()); mpg.execute(); } }
运行main()方法，其中模块名为“包名”，表名为“数据库表名”；
