struts2+Hibernate实现用户登陆功能
实现的功能，在登陆页面输入Username和PassWord后，将username和password通过Hibernate匹对数据库是否含有一样的username和password，若有则登陆进去，若没有则返回到登陆页面
显示层

model层
User
package com.zs.model; public class User { private String username; private String password; private Short sex; private String email; private String address; private String grade; public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public Short getSex() { return sex; } public void setSex(Short sex) { this.sex = sex; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } public String getAddress() { return address; } public void setAddress(String address) { this.address = address; } public String getGrade() { return grade; } public void setGrade(String grade) { this.grade = grade; } }
User.hbm.xml:
<?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <!-- Generated 2014-12-14 14:51:48 by Hibernate Tools 3.4.0.CR1 --> <hibernate-mapping> <class name="com.zs.model.User" table="USER"> <id name="username" type="java.lang.String"> <column name="USERNAME" /> <generator class="assigned" /> </id> <property name="password" type="java.lang.String"> <column name="PASSWORD" /> </property> <property name="sex" type="java.lang.Short"> <column name="SEX" /> </property> <property name="email" type="java.lang.String"> <column name="EMAIL" /> </property> <property name="address" type="java.lang.String"> <column name="ADDRESS" /> </property> <property name="grade" type="java.lang.String"> <column name="GRADE" /> </property> </class> </hibernate-mapping>
Hibernate：
配置hibernate.hbm.xml：
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <!--连接数据库的配置--> <property name="connection.username">root</property> <property name="connection.password">root</property> <property name="connection.driver_class">com.mysql.jdbc.Driver</property> <property name="connection.url">jdbc:mysql:///hibernate</property> <property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property> <property name="show_sql">true</property> <property name="hibernate.format_sql">true</property> <property name="hibernate.hbm2ddl.auto">update</property> <!--数据库映射Java用户--> <mapping resource="com/zs/model/User.hbm.xml" /> </session-factory> </hibernate-configuration>
Struts：
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd"> <struts> <package name="default" extends="struts-default"> <!--登陆主页面时候的Action--> <action name="index"> <result>/index.jsp</result> </action> <!--在index.jsp提交submit后若登陆成功则转到adminlogin,否则转到index--> <action name="userlogin" class="com.zs.web.admin.AdminLoginAction"> <result name="success">/admin/adminlogin.jsp</result> <result name="input">/index.jsp</result> </action> </package> </struts>
Action:
package com.zs.web.admin; import java.util.Map; import org.apache.struts2.interceptor.SessionAware; import com.opensymphony.xwork2.ActionSupport; import com.zs.dao.UserDao; import com.zs.dao.impl.UserDaoImpl; import com.zs.model.User; public class AdminLoginAction extends ActionSupport implements SessionAware { /** * */ private static final long serialVersionUID = 1L; UserDao dao = new UserDaoImpl(); private String username; private String password; private Map<String,Object> session; public String execute(){ User user = dao.isValidAdmin(username, password);//将username和password传递到dao层交个hibernate判断 if(user!=null){ session.put("user", user);//若登陆成功则将该user记录在session中 return SUCCESS; }else{ addActionError("你没有管理权限"); return INPUT; } } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public Map getSession() { return session; } public void setSession(Map session) { this.session = session; } }
判断用户和密码是否存在于数据库中
package com.zs.dao.impl; import java.util.List; import com.zs.dao.BaseDaoImpl; import com.zs.dao.UserDao; import com.zs.model.User; public class UserDaoImpl extends BaseDaoImpl implements UserDao { @Override public void saveUser(User user) { // TODO Auto-generated method stub } @Override public List<User> getAll(Class clazz) { // TODO Auto-generated method stub return null; } @Override public User isValidUser(String username, String password) { // TODO Auto-generated method stub return null; } //判断数据库中时候含有该用户 @Override public User isValidAdmin(String username, String password) { User user = null; //调用hibernate List<User> list =super.search("FROM User WHERE grade='admin' AND username ='"+username+"' AND password = '"+password+"'"); if(list!=null && list.size()>0){//若找到的list不为空那么则说明数据库中包含这个人 user = list.get(0); } return user; } }
Hibernate初始化借口并且从数据库中取数据
package com.zs.dao; import java.util.List; import org.hibernate.Query; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.Transaction; import org.hibernate.cfg.Configuration; import org.hibernate.service.ServiceRegistry; import org.hibernate.service.ServiceRegistryBuilder; public class BaseDaoImpl implements IBaseDao { private SessionFactory sessionFactory; private Session session; private Transaction transaction; //初始session接口 public void init(){ Configuration configuration = new Configuration().configure(); ServiceRegistry serviceRegistry = new ServiceRegistryBuilder().applySettings(configuration.getProperties()) .buildServiceRegistry(); sessionFactory = configuration.buildSessionFactory(serviceRegistry); session = sessionFactory.openSession(); transaction = session.beginTransaction(); } @Override public Session getSession() { init(); return session; } @Override public void closeSession() { session.close(); } @Override public List search(String hql) { //调用session接口 Session session = null; session = getSession(); List alist = null; alist = session.createQuery(hql).list();//从数据库中查询 session.close(); return alist; } }
可以先建好一个名为User的数据库，设置一个用户，然后便可以测试了
