簡單的介面登入實現（struts+hibernate實現）

#建立表User
CREATE TABLE USEE(
ID int(11),
NUM VARCHAR(45),
NAME VARCHAR(45),
PASSWORD VARCHAR(45),
PRIMARY KEY (ID))在編譯器中生成相應的bean類以及對映xml(也可以使用註解)
public class Usee implements Serializable {
private int ID;
private String num;
private String name;
private String password;
public 新增hibernate.cfg.xml配置
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!--配置資料庫JDBS的驅動-->
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/leehuan</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password">lihuan</property>
<property name="connection.pool_size">1</property>
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="current_session_context_class">thread</property> <!--全域性事務-->
<property name="connection.isolation">4</property> <!--設定隔離級別-->
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="show_sql">true</property>
<property name="format_sql">true</property>
<mapping resource="Usee-hbm.xml"/>
<mapping resource="User-hbm.xml"/>
</session-factory>
</hibernate-configuration>然後開始生成Action
package lee.struts;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
import lee.Hibernate.Usee;
import lee.Hibernate.User;
import lee.Hibernate.UserDAO;
import org.apache.commons.logging.Log;
import org.apache.struts2.ServletActionContext;
import javax.servlet.http.HttpServletRequest;
/**
* Created by user on 16-12-22.
*/
public class LoginAction extends ActionSupport {
private String name;
private String pwd;
public String getName() {
return name;
}
public String getPwd() {
return pwd;
}
public void setName(String name) {
this.name = name;
}
public void setPwd(String pwd) {
this.pwd = pwd;
}
@Override
public String execute() throws Exception {
Login();
return super.execute();
}
public String Login(){
ActionContext context = ActionContext.getContext();
HttpServletRequest request = ServletActionContext.getRequest();
String name = (String) request.getParameter("name");
String pwd = (String) request.getParameter("pwd");
if (name.isEmpty() || pwd.isEmpty()){
return ERROR;
}else {
Usee login = UserDAO.login(name, pwd);
if(login!=null){
return SUCCESS;
}else {
return ERROR;
}
}
}
}其中的UserDao.Login(name,pwd)用來進行傳值，同時進行資料庫的查詢
public class UserDAO {
public static Usee login(String name,String pwd){
Session session = HibernateUtls.getSession();
List<Usee> list = new ArrayList<>();
list = session.createQuery("from Usee u where u.name=? and u.password=?").setParameter(0,name).setParameter(1,pwd).list();
if(list.size()!=0) {
Usee usee = list.get(0);
return usee;
}else {
return null;
}
}
}開始配置struts.xml
<?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" namespace="/" extends="struts-default">
<action name="login" class="lee.struts.LoginAction">
<result name="success">/success.jsp</result>
<result name="error">/error.jsp</result>
</action>
</package>
</struts>新增suceess.jsp與error.jsp,在index.jsp中新增form表單
index.jsp:
