Java 代碼

User 實體

public class User {
    private Integer pid; private String name, password; private Double height;
    // getter/setter/構造器
}

User.hbm.xml

<class name="cn.bj.ssh.entity.User" table="user">
    <id name="pid" column="pid"><generator class="native"/></id>
    <property name="name" column="name" length="20"/>
    <property name="password" column="password" length="20"/>
    <property name="height" column="height"/>
</class>

UserDao

public class UserDao {
    private SessionFactory sessionFactory;
    public void save(User user) {
        sessionFactory.getCurrentSession().save(user);
    }
}

UserService

@Transactional
public class UserService {
    private UserDao userDao;
    public void save(User user) { userDao.save(user); }
}

UserAction

public class UserAction extends ActionSupport implements ModelDriven<User> {
    private User user = new User();
    private UserService userService;
    public User getModel() { return user; }
    public void setUserService(UserService userService) { this.userService = userService; }
    public String save() {
        userService.save(user);
        return "loginSuccess";
    }
}

addUser.jsp

<s:form action="user_save" method="post" namespace="/" theme="simple">
<table border="1" width="400">
    <tr><td>用戶名</td><td><s:textfield name="name"/></td></tr>
    <tr><td>密碼</td><td><s:textfield name="password"/></td></tr>
    <tr><td>身高</td><td><s:textfield name="height"/></td></tr>
    <tr><td colspan="2"><input type="submit" value="添加"/></td></tr>
</table>
</s:form>

運行驗證

1. 啟動 Tomcat，訪問 https://localhost:8080/專案名/addUser.jsp。
2. 填寫表單提交，控制台輸出 Hibernate SQL，數據庫 user 表新增記錄。
3. 頁面跳轉至 index.jsp（需自建）。
