                            .formatServiceImplFileName("%sServiceImpl")
                            .entityBuilder()  //实体策略配置

                            .mapperBuilder()    //mapper 策略配置
                            .enableBaseResultMap()  //生成通用的resultMap
                            .superClass(BaseMapper.class)
                            .formatMapperFileName("%sMapper")
                            .enableMapperAnnotation()
                            .formatXmlFileName("%sMapper");
                })
                .templateEngine(new FreemarkerTemplateEngine()) // 使用Freemarker引擎模板，默认的是Velocity引擎模板
                .execute();
    }
    // 处理 all 情况
    protected static List<String> getTables(String tables) {
        return "all".equals(tables) ? Collections.emptyList() : Arrays.asList(tables.split(","));
    }
}

可以根据自己的需要，选择要表生成对应的代码，也可以直接输入all来全部生成。例如需要生成system_user表对应的代码，只需要在终端输入system_user。多个表的话，只需要用逗号隔开。
生成全部代码：

多个表生成对应的代码
