Mybatis plus 代码生成，提高开发效率 使用mybatis generator 工具可生成代码第一步 pom.xml中 引入依赖下发引入generator 包与模板引擎velocity包 <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-generator</artifactId> <version>3.3.1</version> </dependency> <dependency> <groupId>org.apache.velocity</groupId> <artifactId>velocity-engine-core</artifactId> <version>2.3</version> </dependency>新建类，执行main文件public class GeneratorTest { //代码生成保存目录 private final static String out="J:\\DEMO\\code\\api-server\\tmp"; //JDBC数据源 private final static String jdbc="jdbc:mysql://localhost:3306/java_dev?useUnicode=true&useSSL=false&characterEncoding=utf8"; //数据库账号 private final static String db_user="root"; //数据库密码 private final static String db_paswword="root"; //表前缀 private final static String table_prefix="eb_"; //包名 private static final String package_name="com.gxxblw.web"; private static final String author="哈根达斯"; public static void main(String[] args) { AutoGenerator mpg = new AutoGenerator(); File file=new File(out); File[] files= file.listFiles(); for (int i=0;i<files.length;i++){ files[i].deleteOnExit(); } // 全局配置 GlobalConfig gc = new GlobalConfig(); gc.setOutputDir(out); gc.setAuthor(author); gc.setOpen(true); //自定义Mappter文件名 gc.setMapperName("%sDao"); 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); // dsc.setSchemaName("public"); dsc.setDriverName("com.mysql.jdbc.Driver"); dsc.setUsername(db_user); dsc.setPassword(db_paswword); mpg.setDataSource(dsc); /*TemplateConfig templateConfig = new TemplateConfig(); templateConfig.setMapper("dao"); templateConfig.setEntityKt("domain"); templateConfig.setXml(null); mpg.setTemplate(templateConfig);*/ // 包配置 PackageConfig pc = new PackageConfig(); pc.setModuleName(scanner("模块名")); pc.setParent(package_name); pc.setMapper("dao"); pc.setEntity("model"); 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.setInclude(scanner("表名，多个英文逗号分割").split(",")); strategy.setTablePrefix(table_prefix); mpg.setStrategy(strategy); mpg.setTemplateEngine(new VelocityTemplateEngine()); mpg.execute(); } 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.isNotBlank(ipt)) { return ipt; } } throw new MybatisPlusException("请输入正确的" + tip + "！"); } }执行成功后保存目录将生成模板代码，更多参数可查看文档 查看代码生成
