实战FinalDb-afinal框架进阶

[

"在实战FinalDb中，我们学习了如何创建User.java类并实现其属性和get/set方法。接下来，我们将深入探索如何使用afinal框架进行数据库操作。",

"

1. 首先，我们需要编写User.java类的属性和方法：",

"java

",

"class User {

",

" private int id;

",

" private String name;

",

" // getters and setters...

",

"}

",

"",

"

2. 接着，我们通过FinalDb类来操作数据库：",

"java

",

"FinalDb fd = FinalDb.create(this);

",

"User user = new User();

",

"user.setName(\"覃基权\");

",

"fd.save(user);

",

"List list = fd.findAll(User.class);

",

"tv_name.setText(list.get(0).getName());

",

"",

"

3. 最后，我们将在/data/package/database目录下创建afinal.db数据库，并使用它来存储我们的User数据：",

"bash

",

"# 在终端中进入/data/package/database目录

",

"# 执行以下命令创建数据库和表结构

",

"echo \"create database afinal;\" | mysql -u root -p

",

"echo \"use afinal;\" | mysql -u root -p

",

"echo \"create table com_itcast_afinal_User (id int not null primary key, name varchar(255));\" | mysql -u root -p

",

""
