Spring集成Struts与Hibernate入门详解
作者:jiangtao
这篇文章主要给大家介绍了关于Spring集成Struts与Hibernate的相关资料,文中介绍的非常详细,对大家具有一定的参考价值,需要的朋友们下面来一起看看吧。
前言
最近将Spring,Struts,Hiberbate基础已经学习完成。想自己把这三个框架集成一下,然后再写一个后台管理网站练练手。Spring的作用是依赖注入,而Struts是显示层的东西,这两个框架集成后是什么样子。一边学习,一边记录。上车。
Spring集成所需jar包
首先,Spring集成Struts,那么applicationContext.xml和struts.xml,web.xml肯定是不能少的。前面两个是Spring和Struts的配置文件,后面一个是整个web的全局配置文件。在每个配置文件中应该怎么配置,怎么相互关联呢。其实就是将Struts中指定的Action 类为Spring注入的类。
三大框架集成开发并不难,难的地方在于各个包的依赖要搞清楚,版本之间的差异也是一点。下面列出Spring集成Struts所依赖的包:
依赖包
此处所有依赖为Struts2.0和Spring3.0。版本有点老,我用最新版的始终集成不正确。等搞好了再升级版本。

集成
model层
新建Usermodel,如下:
package com.action; import java.io.Serializable; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.Id; @Entity @javax.persistence.Table(name="user") public class User implements Serializable{ private static final long serialVersionUID = 1L; @Id @GeneratedValue @Column(name="id") public int id; @Column(name="name") public String name; @Column(name="password") public String password; public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } @Override public String toString() { return "User [name=" + name + ", password=" + password + "]"; } }
dao层
新建dao接口:
package com.dao.impl; import java.util.List; import com.action.User; import com.action.UserAction; public interface UserDao { public void save(User action); public User getUser(int id); public void update(User action); public void delete(User userAction); public List<User> findByName(String name); }
实现dao接口
package com.dao.impl; import java.util.List; import org.hibernate.SessionFactory; import org.springframework.orm.hibernate3.HibernateTemplate; import com.action.User; import com.action.UserAction; public class UserDaoImpl implements UserDao { private SessionFactory sessionFactory; private HibernateTemplate mHibernateTemplate; public SessionFactory getSessionFactory() { return sessionFactory; } public void setSessionFactory(SessionFactory sessionFactory) { this.sessionFactory = sessionFactory; } public HibernateTemplate getHbernateTemplate() { if (mHibernateTemplate==null) { mHibernateTemplate = new HibernateTemplate(sessionFactory); } return mHibernateTemplate; } public void save(User action) { // TODO Auto-generated method stub getHbernateTemplate().save(action); } public User getUser(int id) { // TODO Auto-generated method stub User userAction = getHbernateTemplate().get(User.class, new Integer(id)); return userAction; } public void update(User action) { // TODO Auto-generated method stub getHbernateTemplate().update(action); } public void delete(User userAction) { // TODO Auto-generated method stub getHbernateTemplate().delete(userAction); } @SuppressWarnings("unchecked") public List<User> findByName(String name) { // TODO Auto-generated method stub String queryString = "from User u where u.name like ?"; return getHbernateTemplate().find(queryString); } }
view层
显示以及action
/** * */ package com.action; import javax.servlet.http.HttpServletResponse; import org.apache.struts2.ServletActionContext; import com.dao.impl.UserDaoImpl; import com.opensymphony.xwork2.ActionSupport; /** * @author kevin * */ public class UserAction extends ActionSupport { public String name; public String password; private UserDaoImpl userDao; public String getName() { return name; } public void setUserDao(UserDaoImpl userDao) { this.userDao = userDao; } public UserDaoImpl getUserDao() { return userDao; } public void setName(String name) { this.name = name; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } @Override public String execute() throws Exception { // 不能直接new 得从applicationContext中获取 HttpServletResponse response = ServletActionContext.getResponse(); response.setContentType("text/xml;charset=UTF-8"); User user = new User(); user.name = name; user.password = password; userDao.save(user); response.getWriter().write(user.toString()); return "success"; } }

配置文件
添加全局web配置文件
<?xml version="1.0" encoding="UTF-8"?> <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" id="WebApp_ID" version="3.0"> <display-name>SpringSS</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> <filter> <filter-name>struts2</filter-name> <filter-class> org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter </filter-class> </filter> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
Spring配置文件
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd"> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName"> <value>com.mysql.jdbc.Driver</value> </property> <property name="url"> <value>jdbc:mysql://localhost/spring</value> </property> <property name="username"> <value>root</value> </property> <property name="password"> <value>123456</value> </property> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> <property name="dataSource"> <ref local="dataSource"/> </property> <property name="annotatedClasses"> <list> <value>com.action.User</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> <prop key="show_sql">true</prop> </props> </property> </bean> <bean id="userDao" class="com.dao.impl.UserDaoImpl"> <property name="sessionFactory"> <ref local="sessionFactory"/> </property> </bean> </beans>
Struts配置文件
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> <constant name="struts.objectFactory" value="spring" /> <package name="default" extends="struts-default"> <action name="user" class="userAction"> <result name="success">/user.jsp</result> </action> </package> </struts>
结果显示
输入页面
结果页面
数据库
最后看起来,还是不难的嘛。其实UserDao可以抽象出来,只需要单次注入,等以后再完善。
