我这里使用的数据库是mysql5.0 数据是上课用的。这些都不是重点,重要的是学会这个方法;
创建好数据库:
create database jboadefault character set utf8;
show create database jboa1;
然后执行数据脚本

创建好Web Project后,加入Hibernate支持
选择配置好的数据库:
new 新建一个包:
添加Spring支持:
下面的意思是 : 在配置文件里面创建sessionFactory的引用
反向生成Hibernate 实体类: 右上角却换到Databse Explorer perspective 视图模式 下
选择要生成的表 右击 → Hibernate Reverse Engineering
MySql的主键自动生成策略可以用identity 或者native
需要改生成的类的 类名或者属性名 可以在这里改,一般我们要修改一下实体类的类名,因为有时候不可以和数据库一样的名字;
这里要指定主键类型,因为这个类主键不是自动生成的 是手动添加的,其他不用指定默认是前面指定的(自动生成)。
将自动生成的 类 和配置文件 都整理到com.jboa.model包中
将所有配置文件hbm.xml前面加上整理到的 包
<hibernate-mapping package="com.jboa.model">
然后将他们都配置到hibernate.cfg.xml文件可以直接选中配置文件然后拖拽到图形化界面的Hibernate配置文件,如图:
<mapping resource="com/jboa/model/Employee.hbm.xml" />
…..
在web.xml加上Spring的监听器
<!-- 整合Spring --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>
添加Struts2支持
整合好了。
添加dao接口
public interface EmployeeDao extends Serializable { public Employee findById(String sn); }
添加接口的实现类
public class EmployeeDaoImpl extends HibernateDaoSupport implements EmployeeDao { public Employee findById(String sn) { return this.getHibernateTemplate().get(Employee.class, sn); } }
在Spring配置文件applicationContext.xml 配置HibernateDaoSupport的sessionFactory
<bean id="employeeDao" class="com.jboa.dao.impl.EmployeeDaoImpl" depends-on="sessionFactory"> <property name="sessionFactory" ref="sessionFactory"></property> </bean>
创建Action ( EmployeeAction )
private Employee employee; private EmployeeDao employeeDao; //设置set方法,这样在Spring配置文件就可以配置值了 public void setEmployeeDao(EmployeeDao employeeDao) { this.employeeDao = employeeDao; } //登陆验证 public String login() { Employee e = employeeDao.findById(employee.getSn()); if (e != null && employee.getPassword().equals(e.getPassword())) { ActionContext.getContext().getSession().put("loginUser", e); return SUCCESS; } return INPUT; } public Employee getEmployee() { return employee; } public void setEmployee(Employee employee) { this.employee = employee; }
在dao的实现类实现findById方法
public class EmployeeDaoImpl extends HibernateDaoSupport implements EmployeeDao { public Employee findById(String sn) { return this.getHibernateTemplate().get(Employee.class, sn); } }
在Spring的配置文件applicationContext.xml配置
<!-- scope="prototype"多例,表示每次使用都创建一个新的,单例则不创建新的 --> <bean id="employeeAction" class="com.jboa.action.EmployeeAction" scope="prototype"> <property name="employeeDao" ref="employeeDao"></property> </bean>
配置struts.xml文件
<constant name="struts.devMode" value="true"></constant> <package name="jboa" extends="struts-default" namespace="/"> <action name="login" class="employeeAction" method="login" > <result>/index.jsp</result> <result name="input">/login.jsp</result> </action> </package>
这样就可以了 接下来在WebRoot创建登陆页面测试 login.jsp,在数据库employee表添加登陆测试数据
<form action="login" method="post"> 登陆名:<input name="employee.sn" /><br/> 密码:<input type="password" name="employee.password" /><br/> <input type="submit" /> </form>
测试 部署启动tomcat,访问login.jsp,登陆成功;
成功!
