Spring集成Struts与Hibernate入门详解

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";
 }
}

<!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>

结果显示

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。
