上面是相关依赖，lombok 是简化代码的配置代码中会出现看下方代码
方式一
public class CodeGenerator {

*/
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();
String projectPath = System.getProperty("user.dir");
gc.setOutputDir(projectPath + "/src/main/java");
gc.setAuthor("jobob");
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/ant?useUnicode=true&useSSL=false&characterEncoding=utf8");
// dsc.setSchemaName("public");
dsc.setDriverName("com.mysql.jdbc.Driver");

dsc.setPassword("密码");
mpg.setDataSource(dsc);
// 包配置
PackageConfig pc = new PackageConfig();
pc.setModuleName(scanner("模块名"));
pc.setParent("com.baomidou.ant");
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 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.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.baomidou.ant.common.BaseEntity");
strategy.setEntityLombokModel(true);
strategy.setRestControllerStyle(true);
strategy.setSuperControllerClass("com.baomidou.ant.common.BaseController");
strategy.setInclude(scanner("表名，多个英文逗号分割").split(","));
strategy.setSuperEntityColumns("id");
strategy.setControllerMappingHyphenStyle(true);
strategy.setTablePrefix(pc.getModuleName() + "_");
mpg.setStrategy(strategy);
mpg.setTemplateEngine(new FreemarkerTemplateEngine());
mpg.execute();
}
