使用Myeclipse10.0自动生成搭建SSH框架(数据库表自动反向转换成Hibernate实体)实现用户登陆

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!
