AutoGenerator generator = new AutoGenerator();

// 数据源配置
DataSourceConfig dataSourceConfig = new DataSourceConfig();
dataSourceConfig.setUrl("jdbc:mysql://localhost:3306/your_db?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai");
dataSourceConfig.setDriverName("com.mysql.cj.jdbc.Driver");

generator.setDataSource(dataSourceConfig);

// 全局配置

generator.setGlobalConfig(globalConfig);

// 包名配置
PackageConfig packageConfig = new PackageConfig();
packageConfig.setParent("com.example.demo");
packageConfig.setModuleName("system");
generator.setPackageInfo(packageConfig);

// 策略配置
StrategyConfig strategy = new StrategyConfig();
strategy.setNaming(NamingStrategy.underline_to_camel); // 表转类名策略
strategy.setColumnNaming(NamingStrategy.underline_to_camel); // 字段转属性名策略
strategy.setEntityLombokModel(true); // 使用Lombok
strategy.setRestControllerStyle(true); // Controller为RestController风格
strategy.setInclude("user", "role"); // 需要生成的表名
generator.setStrategy(strategy);

// 执行生成
generator.execute();

TemplateConfig templateConfig = new TemplateConfig();
templateConfig.setController("templates/controller.java.ftl");
generator.setTemplate(templateConfig);

strategy.setEntityTableFieldAnnotationEnable(true);
