Struts2+Spring3+Hibernate3+MySQL简单登录实现-演道网

使用Struts2+Spring3+Hibernate3+MySQL实现简单登录,下面就开始说小编写的代码。

1.导入相关的jar包

2.建立数据库

1 create table account(
2 id int(10),
3 user varchar(50),
4 paw varchar(50)
5 );
6 insert into account values(1,'admin','admin'); 

3.建立包结构

 

4.配置文件的配置及代码

4.1 数据库配置文件:db.properties

1 #jdbc
2 jdbc.driver=com.mysql.jdbc.Driver
3 jdbc.url=jdbc:mysql://127.0.0.1:3306/test
4 jdbc.username=root
5 jdbc.password=

4.2 spring配置文件:applicationContext.xml

71         <property name="accountManager" ref="accountManager">property>
72     bean>
73 beans>

注:上述配置中注释掉的事物部分,因为小编未使用到,所以也没有认证,在配置时可去掉

4.4 配置完spring,可以先测试下配置是否正确

 1 package ssh.ft.test;
 2 
 3 import java.util.List;
 4 
 5 import org.hibernate.SessionFactory;
 6 import org.junit.Test;
 7 import org.springframework.context.ApplicationContext;
 8 import org.springframework.context.support.ClassPathXmlApplicationContext;
 9 
10 import ssh.ft.entity.Account;
11 
12 public class DBTest {
13     @Test
14     public void test1() {
15         String config = "configs/applicationContext.xml";
16         ApplicationContext ac = new ClassPathXmlApplicationContext(config);
17         SessionFactory sf = ac.getBean(SessionFactory.class);
18         String sql = "from Account";
19         @SuppressWarnings("unchecked")
20         List list = sf.openSession().createQuery(sql).list();
21         System.out.println(list.size());
22     }
23 }

若配置正确则有如下结果:红色框中的数字1表示数据库中表account中有一条数据,若未出现正确结果,则需要检查上述代码哪里出错,或者是jar的问题

因为小编也遇到过很多jar包不全之类的问题,务必正确之后再往下编写,否则到后面错误或更多导致无法查找

4.5 struts配置文件:struts.xml

 1 xml version="1.0" encoding="UTF-8" ?>

4.6 hibernate配置文件:hibernate.cfg.xml 

 1 DOCTYPE hibernate-configuration PUBLIC
 2     "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
 3     "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

16         
17         <mapping resource="configs/account.hbm.xml" />
18     session-factory>
19 hibernate-configuration> 

hibernate配置文件还有一个实体映射文件:account.hbm.xml

 1 DOCTYPE hibernate-mapping PUBLIC 
 2     "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
 3     "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
 4 <hibernate-mapping>
 5     <class name="ssh.ft.entity.Account" table="account">

 8             
 9             <generator class="native">generator>
10         id>
11         
12         <property name="user">property>
13         <property name="paw">property>
14     class>
15 hibernate-mapping> 

在hibernate.cfg.xml中的

  

这个语句里面的account.hbm.xml就是指上述的account.hbm.xml配置文件

4.7 web.xml配置文件

 1 xml version="1.0" encoding="UTF-8"?>
 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">

注:上述小编注释了一个未解决的问题,就是struts.xml文件一定要在src目录下方,否则会报错,如果想放在其他地方的话,若有人解决希望一定要留言告诉小编

4.8 实体类:Account.java

 1 package ssh.ft.entity;
 2 
 3 public class Account {
 4     private Integer id;
