SSH项目整合
1. 加上lib包
2. 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>
</struts>
3. applicationContext.xml
<?xml version="1.0" encoding="utf-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

4. web.xml

</context-param>
<filter>

5. 登录页面的form表单
<form action="loginAction" method="post">
用户名：<input type="text" name="user.name" size="20" /><br/>
用户名：<input type="password" name="user.pwd" size="20" /><br/>
<input type="submit" value="提交" size="20" /><br/>
</form>
6. action类的创建
public class UserAction extends ActionSupport{
//User属性，而且该对象的name和Pwd属性都能够被自动赋值
private User user;
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
public String executeLogin(){
if(("ysj").equals(user.getName())){
return SUCCESS;//常量
}else{
return INPUT;
}
}
}
7. struts.xml配置文件，配置action
<!-- 配置action -->
<package name="pk" extends="struts-default">
<!-- 与配置servlet一样 -->
<action name="loginAction" class="action.UserAction" method="executeLogin">
<result name="success">/wel.jsp</result>
<result name="input">/fail.jsp</result>
</action>
</package>
8. domain中的类
public class User implements Serializable{
private String id;
private String name;
private String pwd;
9. User.hbm.xml映射文件的配置
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="domain">
<class name="User" table="user_table">
<id name="id">
<generator class="UUID">
</generator>
</id>
<property name="name" column="name"></property>
<property name="pwd" column="pwd"></property>
</class>
</hibernate-mapping>
10. 将映射文件加入sessionFactory的配置中
<property name="mappingResources">
<list>
<value>domain/User.hbm.xml</value>
</list>
</property>
11. dao层代码的搭建
public class UserDaoImpl extends HibernateDaoSupport implements UserDao{
public int getUser(User user) {
String sql = "from User where name=? and pwd=?";
return this.getHibernateTemplate().
find(sql,user.getName(),user.getPwd()).size();
}
}
12. 在applicationContext.xml中配置dao的bean
<bean id="userDao" class="dao.impl.UserDaoImpl">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
13. 测试spring与Hibernate的结合
public class Test {
//执行完该Main方法后，数据库中是否生成了一张user-table表
public static void main(String[] args) {
ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");
UserDao dao = (UserDao) ac.getBean("userDao");
User user = new User();
dao.getUser(user);
}
}
14. service层的而实现
a) private UserDao userDao
15. 配置service，做dao的注入
<bean id=”userService” class=””>
<proterty name=” userDao” ref=”userDao” />
</bean>
16. 修改action类
private UserService userService
选作：登录成功后，显示用户列表
listAction UserService
