Spring集成Struts與Hibernate入門詳解

更新時間：2017年03月14日 08:40:29 作者：jiangtao

這篇文章主要給大家介紹了關(guān)于Spring集成Struts與Hibernate的相關(guān)資料，文中介紹的非常詳細，對大家具有一定的參考價值，需要的朋友們下面來一起看看吧。

前言

最近將Spring,Struts,Hiberbate基礎(chǔ)已經(jīng)學(xué)習(xí)完成。想自己把這三個框架集成一下，然后再寫一個后臺管理網(wǎng)站練練手。Spring的作用是依賴注入，而Struts是顯示層的東西，這兩個框架集成后是什么樣子。一邊學(xué)習(xí)，一邊記錄。上車。

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。前面兩個是Spring和Struts的配置文件，后面一個是整個web的全局配置文件。在每個配置文件中應(yīng)該怎么配置，怎么相互關(guān)聯(lián)呢。其實就是將Struts中指定的Action 類為Spring注入的類。

三大框架集成開發(fā)并不難，難的地方在于各個包的依賴要搞清楚，版本之間的差異也是一點。下面列出Spring集成Struts所依賴的包:

依賴包

此處所有依賴為Struts2.0和Spring3.0。版本有點老，我用最新版的始終集成不正確。等搞好了再升級版本。

集成

model層

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層

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);
}

實現(xiàn)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層

顯示以及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 得從applicationContext中獲取
 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";
 }
}
