使用Hibernate开发用户注册功能：
用户在register.jsp表单成功后，页面跳转到login.html，数据库中会存放用户注册的信息

用户实体层
private String id; private String username; private String password; private String name; private String email; private String telephone;
用户提交表单，发送请求UserAction_register到Web层userService.java
public String register() throws Exception { user.setId(UUID.randomUUID().toString()); UserService userService = new UserService(); System.out.println(user); userService.addUser(user); return "toLogin"; }
在domain层中的User.hbm.xml配置传传入数据库Hibernate的事务
<hibernate-mapping> <class name="com.Gary.domain.User" table="user"> <!-- id元素 name:实体中的属性 colum(可选):数据库的列名 type(可选): 填写列(属性)的类型.hibernate会自动检测实体的属性类型. 每个类型有三种填法: java类型|hibernate类型|数据库类型 length(可选):配置数据库中列的长度. 默认值:使用数据库类型的最大长度 --> <id name="id" column="id"> <!-- 主键生成策略(手动生成) (最后讲) 5种 identity:主键自增 sequence:oracle中主键生成的策略 native:identity+sequence (hibernate会根据连接的数据库自动选择(identity,sequence)) uuid:产生随机字符串作为主键,主键必须为String assigned:我们要手动去指定 --> <generator class="assigned"></generator> </id> <!-- property:除了id之外的普通属性 name:实体中的属性 colum(可选):数据库的列名 type(可选): 填写列(属性)的类型.hibernate会自动检测实体的属性类型. 每个类型有三种填法: java类型|hibernate类型|数据库类型 length(可选):配置数据库中列的长度. 默认值:使用数据库类型的最大长度 not-null(可选):配置该属性(列)是否不能为空. 默认值:false --> <property name="username" column="username"></property> <property name="password" column="password"></property> <property name="name" column="name"></property> <property name="email" column="email"></property> <property name="telephone" column="telephone"></property> </class> </hibernate-mapping>
Dao层UserDao.java向数据库传入用户信息
public void addUser(User user) { //使用Hibernate //得到配置信息 Configuration config = new Configuration().configure(); //创建sessionFactiory对象 SessionFactory sessionFactory = config.buildSessionFactory(); //获取session Session session = sessionFactory.openSession(); //打开事务 Transaction transaction = session.beginTransaction(); //存储User对象 session.save(user); //提交事务 transaction.commit(); //关闭资源 session.close(); }
