????????//1.數(shù)據(jù)源配置
????????DataSourceConfig?dataSourceConfig?=?new?DataSourceConfig();
????????dataSourceConfig.setDbType(DbType.MYSQL);//數(shù)據(jù)庫枚舉類型

????????//2.全局配置
????????GlobalConfig?globalConfig?=?new?GlobalConfig();
????????globalConfig.setOpen(false);?//代碼生成后是否自動打開?(代碼生成完成后以文件夾形式彈出來)
????????globalConfig.setOutputDir(System.getProperty("user.dir")+"/src/main/java");//設(shè)置代碼輸出路徑（當前系統(tǒng)項目路徑，源代碼Java里面）

????????strategyConfig.setEntityLombokModel(true);//是否給實體類添加?Lombok?的注解
????????strategyConfig.setNaming(NamingStrategy.underline_to_camel);//表名映射類名，下劃線轉(zhuǎn)駝峰??如：表名 user_address 下劃線轉(zhuǎn)駝峰實體類為 userAddress
????????strategyConfig.setColumnNaming(NamingStrategy.underline_to_camel);//表字段映射類屬性，下劃線轉(zhuǎn)駝峰?如：表字段 user_id 下劃線轉(zhuǎn)駝峰實體類屬性 userId
