菜鳥學習Spring——60s學會Spring與Hibernate的集成 · 菜鳥學SSH

## 一、概述。 Spring與Hibernate的集成在企業應用中是很常用的做法通過Spring和Hibernate的結合能提高我們代碼的靈活性和開發效率,下面我就一步一步的給大家講述Spring如何和Hibernate集成的。 ## 二、代碼演示。導入Hibernate的jar包 Hibernate-3.2/lib/*.jarHibernate-3.2/hibernate3.jar 還有導入Spring的相關jar包我用的數據庫是MySql所以要導入MySql的驅動jar包： mysql-connector-java-3.1.13-bin.jar 目錄結構: ![](https://box.kancloud.cn/2016-02-22_56caddfc479aa.jpg) Hibernate的實體映射: Log.java ~~~ package com.tgb.usermgr.domain;

} public void setType(String type) { this.type = type; } public String getDetail() { return detail; } public void setDetail(String detail) { this.detail = detail; } public Date getTime() { return time; } public void setTime(Date time) { this.time = time; } } ~~~ User.java ~~~ package com.tgb.usermgr.domain; public class User { private int id; private String name; public int getId() { return id; } public void setId(int id) { this.id = id;

import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.cfg.Configuration; public class HibernateUtils { private static SessionFactory factory; private HibernateUtils() { } static { try { Configuration cfg = new Configuration().configure(); factory = cfg.buildSessionFactory(); }catch(Exception e) { e.printStackTrace(); throw new java.lang.RuntimeException(e); } } public static SessionFactory getSessionFactory() { return factory; } public static Session getSession() { return factory.openSession(); } public static void closeSession(Session session) { if (session != null) { if (session.isOpen()) { session.close(); } } } } ~~~ 業務邏輯實現和接口： LogManager.java ~~~ package com.tgb.usermgr.manager; import com.tgb.usermgr.domain.Log;

} } ~~~ UserManager.java ~~~ package com.tgb.usermgr.manager; import com.tgb.usermgr.domain.User; public interface UserManager { public void addUser(User user) throws Exception; } ~~~ UserManagerImpl.java ~~~ package com.tgb.usermgr.manager;

public class UserManagerImpl extends HibernateDaoSupport implements UserManager { private LogManager logManager; public void addUser(User user) throws Exception { //this.getSession().save(user); this.getHibernateTemplate().save(user); Log log = new Log(); log.setType("操作日志"); log.setTime(new Date()); log.setDetail("XXX"); logManager.addLog(log); throw new Exception(); } public void setLogManager(LogManager logManager) { this.logManager = logManager; } } ~~~ 客戶端的測試類： UserManagerImplTest.java ~~~ package com.tgb.usermgr.manager; import org.springframework.beans.factory.BeanFactory; import org.springframework.context.support.ClassPathXmlApplicationContext; import com.tgb.usermgr.domain.User; import junit.framework.TestCase; public class UserManagerImplTest extends TestCase { public void testAddUser() { BeanFactory factory = new ClassPathXmlApplicationContext("applicationContext-*.xml"); UserManager userManager = (UserManager)factory.getBean("userManager"); User user = new User(); user.setName("張三"); try { userManager.addUser(user); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace();
