Struts2.3 + Spring3.1 + Hibernate3.6 + HTML5 + CSS3整合开发
Struts2.3 + Spring3.1 + Hibernate3.6 + HTML5 + CSS3整合开发
1 项目概述
1.1 必需的软件资源
| JAVA: JDK7 Server: Tomcat7 DB: MySQL5.5 Browser: Firefox3.5 IDE: MyEclispse9 |
1.2 HTML5的部分新特性
本项目采用Struts2的最新版本Struts2.3、Spring的最新版本Spring3.1和Hibernate3.6整合开发，另外在页面设计时采用了HTML5和CSS3技术
在HTML5中，增加了对表单数据的处理功能：如下所示：
-
当输入域为空且失去焦点时，出现提示信息，当输入域获得焦点后，提示信息自动消失
|
|
（2）在<input>标签中就可以验证输入的字段是否合法，不再需要javascript进行验证；另外，对以前的下拉列表也做了改进：

2.3 整合Spring+Hibertnate+c3p0
2.3.1 创建实体模型
本项目采用注解进行实体映射
Person.java
| import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; import javax.persistence.Table;
@Entity @Table(name="tb_person") public class Person {
private int personid;
private String name;
public Person(String name) { this.name = name; }
public Person(){}
@Id @GeneratedValue(strategy=GenerationType.AUTO) public int getPersonid() { return personid; } public void setPersonid(int personid) { this.personid = personid; } public String getName() { return name; } public void setName(String name) { this.name = name; } } |
User.java
| import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; import javax.persistence.Table;
@Entity @Table(name="tb_user") public class User { private int userid; private String username; private String password; private String role;
public User(){}
@Id @GeneratedValue(strategy=GenerationType.AUTO) public int getUserid() { return userid; } public void setUserid(int userid) { this.userid = userid; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public String getRole() { return role; } public void setRole(String role) { this.role = role; } } |
2.3.2 配置c3p0数据源
在applicationContext.xml中添加如下配置：
| <!-- 配置c3p0数据源 --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close"> <property name="driverClass" value="com.mysql.jdbc.Driver"/> <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/ssh2"/> <property name="user" value="root"/> <property name="password" value="root"/> <!--连接池中保留的最大连接数。Default: 15 --> <property name="maxPoolSize" value="15"/> <!--连接池中保留的最小连接数。--> <property name="minPoolSize" value="1"/> <!--初始化时获取三个连接，取值应在minPoolSize与maxPoolSize之间。Default: 3 --> <property name="initialPoolSize" value="3"/> <!--每60秒检查所有连接池中的空闲连接。Default: 0 --> <property name="idleConnectionTestPeriod" value="60"/> <!--最大空闲时间,60秒内未使用则连接被丢弃。若为0则永不丢弃。Default: 0 --> <property name="maxIdleTime" value="60"/> </bean> |
2.3.3 创建SessionFactory
在hibernate.model.xml中作如下配置：
| <mapping class="org.ay.domain.Person"/> <mapping class="org.ay.domain.User"/> |
在applicationContext.xml中添加如下配置：
| <!-- 配置SessionFactory --> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="configLocation" value="classpath:hibernate.model.xml"/> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop> <prop key="hibernate.hbm2ddl.auto">update</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.format_sql">false</prop> </props> </property> </bean> |
2.3.4 创建PersonDAO接口
| package org.ay.dao; import java.util.List; import org.ay.domain.Person; import org.ay.domain.User;
public interface PersonDAO { boolean login(User user);
void add(Person person);
void update(Person person);
void delete(int personid);
List<Person> getPersons(); } |
2.3.5 创建PersonDAOImpl实现类
| package org.ay.dao.impl;
import java.util.Iterator; import java.util.List;
import javax.annotation.Resource;
import org.ay.dao.PersonDAO; import org.ay.domain.Person; import org.ay.domain.User; import org.hibernate.Hibernate; import org.hibernate.Query; import org.hibernate.SessionFactory; import org.hibernate.type.Type; import org.springframework.stereotype.Repository;
@Repository public class PersonDAOImpl implements PersonDAO {
@Resource private SessionFactory sessionFactory;
public boolean login(User user){ String hql = "from User where username=? and password=? and role=?";
String[] params = new String[]{user.getUsername(), user.getPassword(),user.getRole()}; @SuppressWarnings("deprecation") Type[] types = new Type[]{Hibernate.STRING,Hibernate.STRING,Hibernate.STRING};
Query query = sessionFactory.getCurrentSession().createQuery(hql); query.setParameters(params,types); Iterator<?> iter = query.iterate(); if (iter.hasNext()) { return true; } return false; }
public void add(Person person) { sessionFactory.getCurrentSession().save(person); }
public void update(Person person) { Person old = (Person)sessionFactory.getCurrentSession().get(Person.class, person.getPersonid()); old.setName(person.getName()); }
public void delete(int personid) { Person person = (Person)sessionFactory.getCurrentSession().get(Person.class, personid); sessionFactory.getCurrentSession().delete(person); }
@SuppressWarnings("unchecked") public List<Person> getPersons() { return sessionFactory.getCurrentSession().createQuery("from Person").list(); } } |
2.3.6 使用Spring的扫描加注解功能
需要在applicationContext.xml中开启此功能
| <!--扫描加注解功能 --> <context:component-scan base-package="org.ay"/> |
2.3.7 基于XML的声明式事物管理
（1）配置Spring的事务管理器
| <bean id="trManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"/> </bean> |
（2）配置Advice
| <tx:advice id="advice" transaction-manager="trManager"> <tx:attributes> <tx:method name="add*" propagation="REQUIRED"/> <tx:method name="update*" propagation="REQUIRED"/> <tx:method name="del*" propagation="REQUIRED"/> <tx:method name="*" propagation="REQUIRED" read-only="true"/> </tx:attributes> </tx:advice> |
（3）配置PointCut
| <aop:config> <aop:pointcut expression="execution(* org.ay.dao.impl.*.*(..))" id="allMethod"/> <aop:advisor advice-ref="advice" pointcut-ref="allMethod"/> </aop:config> |
2.4 整合Spring+Struts2
2.4.1 在struts.xml中配置
| <global-results> <result name="error">/error.jsp</result> </global-results>
<action name="person_*" class="personAction" method="{1}"> <result name="success">/success.jsp</result> <result name="persons">/person.jsp</result> </action> |
2.4.2 创建PersonAction
| package org.ay.action;
import java.util.List; import javax.annotation.Resource; import org.ay.dao.PersonDAO; import org.ay.domain.Person; import org.ay.domain.User; import org.springframework.stereotype.Controller;
@Controller public class PersonAction {
@Resource private PersonDAO personDAOImpl;
private User user; private List<Person> persons; private String name; private int personid;
public int getPersonid() { return personid; }
public void setPersonid(int personid) { this.personid = personid; }
public String getName() { return name; }
public void setName(String name) { this.name = name; }
public List<Person> getPersons() { return persons; }
public User getUser() { return user; }
public void setUser(User user) { this.user = user; }
public String login(){ boolean ret = personDAOImpl.login(user); if (ret) { return "success"; } return "error"; }
public String add() { personDAOImpl.add(new Person(name)); return "success"; }
public String get() { persons = personDAOImpl.getPersons(); return "persons"; }
public String del() { personDAOImpl.delete(personid); return "success"; } } |
