        //strategy.setExclude("t_");
        mpg.setStrategy(strategy);
        mpg.setTemplateEngine(new FreemarkerTemplateEngine());
        mpg.execute();
    }
}

運行代碼生成器中的 main 方法。就會在項目路徑下生成 controller service entity 等一系列代碼。

單表生成

// 將這個行代碼註解釋放掉，按照控制檯提示輸入表名即可
strategy.setInclude(scanner("表名"));
