1.反向工程生成使用者實體類
User.java
package com.sunline.entity; /** * User entity. @author MyEclipse Persistence Tools */ public class User implements java.io.Serializable { // Fields private Integer userId; private String userName; private String userPassword; private String userStatus; // Constructors /** default constructor */ public User() { } /** full constructor */ public User(String userName, String userPassword, String userStatus) { this.userName = userName; this.userPassword = userPassword; this.userStatus = userStatus; } // Property accessors public Integer getUserId() { return this.userId; } public void setUserId(Integer userId) { this.userId = userId; } public String getUserName() { return this.userName; } public void setUserName(String userName) { this.userName = userName; } public String getUserPassword() { return this.userPassword; } public void setUserPassword(String userPassword) { this.userPassword = userPassword; } public String getUserStatus() { return this.userStatus; } public void setUserStatus(String userStatus) { this.userStatus = userStatus; } }
User.hbm.xml
<?xml version="1.0" encoding="utf-8"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <!-- Mapping file autogenerated by MyEclipse Persistence Tools --> <hibernate-mapping> <class name="com.sunline.entity.User" table="user" catalog="hengfeng"> <id name="userId" type="java.lang.Integer"> <column name="user_id" /> <generator class="native"></generator> </id> <property name="userName" type="java.lang.String"> <column name="user_name" length="40" not-null="true" /> </property> <property name="userPassword" type="java.lang.String"> <column name="user_password" length="30" not-null="true" /> </property> <property name="userStatus" type="java.lang.String"> <column name="user_status" length="30" not-null="true" /> </property> </class> </hibernate-mapping>
Hibernate配置檔案
Hibernate.cfg.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"> <!-- Generated by MyEclipse Hibernate Tools. --> <hibernate-configuration> <session-factory> <property name="dialect"> org.hibernate.dialect.MySQLDialect </property> <property name="connection.url"> jdbc:mysql://localhost:3306/hengfeng?characterEncoding=UTF-8 </property> <property name="connection.username">root</property> <property name="connection.password">******</property> <property name="connection.driver_class"> com.mysql.jdbc.Driver </property> <property name="myeclipse.connection.profile"> com.mysql.jdbc.Driver </property> <property name="show_sql">true</property> <property name="format_sql">true</property> <property name="hbm2ddl.auto">update</property> <mapping resource="com/sunline/entity/Basedata.hbm.xml" /> <mapping resource="com/sunline/entity/Targetdimension.hbm.xml" /> <mapping resource="com/sunline/entity/User.hbm.xml" /> </session-factory> </hibernate-configuration>
Struts 2 配置檔案
Struts.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
<package name="SunlineShow" extends="struts-default">

Hibernate配置檔案解析類
HibernateSessionFactory.java
package com.sunline.dao;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class HibernateSessionFactory {
private SessionFactory sessionFactory;
public HibernateSessionFactory(){
}
public SessionFactory config(){
try{
Configuration configuration= new Configuration();
Configuration configure=configuration.configure("hibernate.cfg.xml");
return configure.buildSessionFactory();
}catch(Exception e){
e.getMessage();
return null;
}
}
public Session getSession(){
sessionFactory=config();
return sessionFactory.openSession();
}
}
資料訪問層Dao類
UserDao.java
package com.sunline.dao;
import java.util.List;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.Transaction;
import com.sunline.entity.User;
public class UserDao {
private Session session;
private Transaction transaction;
private Query query;
HibernateSessionFactory getSession;
public List<User> Login(String user_name,String user_password){
getSession = new HibernateSessionFactory();
session = getSession.getSession();
try{
String hqlsql="from User as u where u.userName=? and u.userPassword=?";
query=session.createQuery(hqlsql);
query.setParameter(0, user_name);
query.setParameter(1, user_password);
List<User> list=query.list();
transaction=session.beginTransaction();
System.out.println("查詢成功!");
transaction.commit();
return list;
}catch(Exception e){
System.out.println("查詢錯誤!");
e.printStackTrace();
return null;
}
}
}
Action控制類
登入控制類:
LoginAction.java
package com.sunline.action;
import java.util.List;
import java.util.Map;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
import com.sunline.dao.UserDao;
import com.sunline.entity.User;
public class LoginAction extends ActionSupport {
private static final long serialVersionUID = 1889710968497585080L;
private String user_name ;
private String user_password;
public String getUser_name() {
return user_name;
}
public void setUser_name(String user_name) {
this.user_name = user_name;
}
public String getUser_password() {
return user_password;
}
public void setUser_password(String user_password) {
this.user_password = user_password;
}
@Override
public String execute() throws Exception {
// TODO Auto-generated method stub
UserDao dao = new UserDao();
List<User> list = dao.Login(this.user_name, this.user_password);
if(list.size()>=1){
ActionContext context = ActionContext.getContext();
Map<String, Object> session = context.getSession();
// session.put("user",list);
session.put("user",this.user_name);
return SUCCESS;
}
else{
return ERROR;
}
}
}
登出控制類:
LogoutAction.java
package com.sunline.action;
import java.util.Map;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
public class LogoutAction extends ActionSupport {
private static final long serialVersionUID = 1L;
@Override
public String execute() throws Exception {
// TODO Auto-generated method stub
Map session = ActionContext.getContext().getSession();
session.remove("user");
return SUCCESS;
}
}
