SSH整合方式二：将hibernate的配置交给Spring管理（Struts2+Spring+Hibernate）

SSH方式：不带hibernate配置文件

一、创建web项目，引入jar和jsp页面

1、第一步：创建web项目，引入jar包

（1）Struts2的jar包：

• jar包路径：struts-2.3.24-all\struts-2.3.24\apps\struts2-blank\WEB-INF\lib
  
• Struts2当中有一些包需要了解的：
  struts2-convention-plugin-2.3.24.jar -------Struts2的注解开发包。
  struts2-json-plugin-2.3.24.jar -----------------Struts2的整合AJAX的开发包
  struts2-spring-plugin-2.3.24.jar---------------Struts2和Spring整合的插件包

（2）Hibernate的jar包：

• a、Hibernate的开发的必须的包：
• jar包路径：hibernate-release-5.0.7.Final\lib\required
  
• b、hibernate和新版jdk可能有一些不兼容，引入4个兼容jar
  下载链接：
  
• c、引入mysql驱动
  
• d、日志记录jar：
  
• e、使用C3P0链接池
  jar路径：\hibernate-release-5.0.7.Final\hibernate-release-5.0.7.Final\lib\optional\c3p0
  
• f、注意：Struts2和Hibernate都引入了一个相同的jar包（javassist包）。需要删除一个
  
  删除版本低的

（3）Spring的jar包：

• IOC的开发:

  
  引入Spring的日志文件
  

• AOP的开发:

  

• JDBC模板的开发:

  

• 只是做事务管理开发

  

• 整合web项目的开发:

  

• 整合单元测试的开发:

  

• 整合Hibernate的开发:

（4）全部的jar

2、第二步：引入配置文件

（1）Struts2的配置文件

• web.xml：
  web.xml当中配置核心过滤器
  
• struts.xml：
  在src下创建struts.xml的配置文件

（2）Spring的配置文件

• web.xml
  在web.xml当中配置核心监听器，启动的时候加载Spring的配置文件，创建工厂，将工厂放入到ServletCont ext当中
  
• applicationContext.xml：
  在src创建applicationContext.xml

• 日志记录：
  在src下创建log4j.properties

### direct log messages to stdout ###log4j.appender.stdout=org.apache.log4j.ConsoleAppenderlog4j.appender.stdout.Target=System.errlog4j.appender.stdout.layout=org.apache.log4j.PatternLayoutlog4j.appender.stdout.layout.ConversionPattern=%d{
   ABSOLUTE} %5p %c{
   1}:%L - %m%n### direct messages to file mylog.log ###log4j.appender.file=org.apache.log4j.FileAppenderlog4j.appender.file.File=c\:mylog.loglog4j.appender.file.layout=org.apache.log4j.PatternLayoutlog4j.appender.file.layout.ConversionPattern=%d{
   ABSOLUTE} %5p %c{
   1}:%L - %m%n### set log levels - for more verbose logging change 'info' to 'debug' #### error warn info debug tracelog4j.rootLogger= info, stdout

3、第三步：创建包结构

4、第四步：创建相关的类

（1）创建实例对象Customer对象

在domain包下先创建

package com.itzheng.ssh.domain;/* * 客户管理的实体类、  CREATE TABLE `cst_customer` (  `cust_id` bigint(32) NOT NULL AUTO_INCREMENT COMMENT '客户编号(主键)',  `cust_name` varchar(32) NOT NULL COMMENT '客户名称(公司名称)',  `cust_source` varchar(32) DEFAULT NULL COMMENT '客户信息来源',  `cust_industry` varchar(32) DEFAULT NULL COMMENT '客户所属行业',  `cust_level` varchar(32) DEFAULT NULL COMMENT '客户级别',  `cust_phone` varchar(64) DEFAULT NULL COMMENT '固定电话',  `cust_mobile` varchar(16) DEFAULT NULL COMMENT '移动电话',  PRIMARY KEY (`cust_id`)) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8; */public class Customer {
   	private Long cust_id;	private String cust_name;	private String cust_source;	private String cust_industry;	private String cust_level;	private String cust_phone;	private String cust_mobile;	public Long getCust_id() {
   		return cust_id;	}	public void setCust_id(Long cust_id) {
   		this.cust_id = cust_id;	}	public String getCust_name() {
   		return cust_name;	}	public void setCust_name(String cust_name) {
   		this.cust_name = cust_name;	}	public String getCust_source() {
   		return cust_source;	}	public void setCust_source(String cust_source) {
   		this.cust_source = cust_source;	}	public String getCust_industry() {
   		return cust_industry;	}	public void setCust_industry(String cust_industry) {
   		this.cust_industry = cust_industry;	}	public String getCust_level() {
   		return cust_level;	}	public void setCust_level(String cust_level) {
   		this.cust_level = cust_level;	}	public String getCust_phone() {
   		return cust_phone;	}	public void setCust_phone(String cust_phone) {
   		this.cust_phone = cust_phone;	}	public String getCust_mobile() {
   		return cust_mobile;	}	public void setCust_mobile(String cust_mobile) {
   		this.cust_mobile = cust_mobile;	}	public Customer() {
   		// TODO Auto-generated constructor stub	}	public Customer(Long cust_id, String cust_name, String cust_source, String cust_industry, String cust_level,			String cust_phone, String cust_mobile) {
   		super();		this.cust_id = cust_id;		this.cust_name = cust_name;		this.cust_source = cust_source;		this.cust_industry = cust_industry;		this.cust_level = cust_level;		this.cust_phone = cust_phone;		this.cust_mobile = cust_mobile;	}	@Override	public String toString() {
   		return "Customer [cust_id=" + cust_id + ", cust_name=" + cust_name + ", cust_source=" + cust_source				+ ", cust_industry=" + cust_industry + ", cust_level=" + cust_level + ", cust_phone=" + cust_phone				+ ", cust_mobile=" + cust_mobile + "]";	}}

（2）在web.action当中创建一个action

package com.itzheng.ssh.web.action;import com.itzheng.ssh.domain.Customer;import com.opensymphony.xwork2.ActionSupport;import com.opensymphony.xwork2.ModelDriven;/* * 客户管理的action的类 */public class CustomerAction extends ActionSupport implements ModelDriven
   
    {
   	//模型驱动使用的对象		private Customer customer = new Customer();	@Override	public Customer getModel() {
   		// TODO Auto-generated method stub		return customer; 	}}
   

（3）创建CustomerService接口以及CustomerServiceImpl实现类（空的即可）

package com.itzheng.ssh.service;/* * 客户管理的业务层的接口 */public interface CustomerService {
   }

package com.itzheng.ssh.service.impl;import com.itzheng.ssh.service.CustomerService;public class CustomerServiceImpl implements CustomerService {
   }

（4）创建CustomerDao接口以及CustomerDaoImpl实现类（空的即可）

package com.itzheng.ssh.dao;/* * 客户管理DAO层的接口 */public interface CustomerDao {
   }

package com.itzheng.ssh.dao.impl;import com.itzheng.ssh.dao.CustomerDao;/* * 客户管理的DAO层的实现类 */public class CustomerDaoUmpl implements CustomerDao {
   }

5、第五步：引入相关的页面

这里引入的是提前写好的jsp页面

6、第六步：修改jsp页面

（1）修改menu.jsp

7、第七步：创建数据库

CREATE DATABASE ssh1;use ssh1; CREATE TABLE `cst_customer` (  `cust_id` bigint(32) NOT NULL AUTO_INCREMENT COMMENT '客户编号(主键)',  `cust_name` varchar(32) NOT NULL COMMENT '客户名称(公司名称)',  `cust_source` varchar(32) DEFAULT NULL COMMENT '客户信息来源',  `cust_industry` varchar(32) DEFAULT NULL COMMENT '客户所属行业',  `cust_level` varchar(32) DEFAULT NULL COMMENT '客户级别',  `cust_phone` varchar(64) DEFAULT NULL COMMENT '固定电话',  `cust_mobile` varchar(16) DEFAULT NULL COMMENT '移动电话',  PRIMARY KEY (`cust_id`)) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

8、第八步：映射Customer文件Customer.hbm.xml

9、第九步：设置service实现类和dao实现类

package com.itzheng.ssh.service.impl;import org.springframework.transaction.annotation.Transactional;import com.itzheng.ssh.dao.CustomerDao;import com.itzheng.ssh.domain.Customer;import com.itzheng.ssh.service.CustomerService;@Transactionalpublic class CustomerServiceImpl implements CustomerService {
   	//注入DAO	private CustomerDao customerDao;	public void setCustomerDao(CustomerDao customerDao) {
   		this.customerDao = customerDao;	}	@Override	public void save(Customer customer) {
   		// TODO Auto-generated method stub		System.out.println("Service当中的save方法执行了。"+customer);		customerDao.save(customer);	}}

package com.itzheng.ssh.dao.impl;import org.springframework.orm.hibernate5.support.HibernateDaoSupport;import com.itzheng.ssh.dao.CustomerDao;import com.itzheng.ssh.domain.Customer;/* * 客户管理的DAO层的实现类 */public class CustomerDaoImpl extends HibernateDaoSupport implements CustomerDao {
   	@Override	public void save(Customer customer) {
   		// TODO Auto-generated method stub		System.out.println("Dao当中的save方法执行了");		//保存customer对象		this.getHibernateTemplate().save(customer);	}}

10、第十步：修改add.jsp页面，设置表单提交的action

二、配置相关配置文件

1、在src下创建jdbc.properties文件

jdbc.driverClass=com.mysql.jdbc.Driverjdbc.url=jdbc:mysql:///ssh1jdbc.username=rootjdbc.password=root

2、在applicationContext.xml当配置

• 配置C3P0数据库连接池
• sessionFactory工厂，设置映射文件
• 配置Action
• 配置Service：将Service交给Spring管理
• 配置DAO
• 配置事务事务管理器
• 开启注解事务

   
   	
    	
    	
    	
    		
     		
     		
     		
     		
     	
    	
    	
    	
    	
    		
     		
     		
     		
     		
      			
      				
       
        org.hibernate.dialect.MySQLDialect
       				
       
        true
       				
       
        true
       				
       
        update
       			
      		
     		
     		
     			
      				
       
        com/itzheng/ssh/domain/Customer.hbm.xml
       			
      		
     	
    	
    	
    		
     	
    	
    	
    	
    		
     		
     	
    	
    	
    		
     		
     	
    	
    	
    		
     		
     	
    	
    	
    
   

将Hibernate的配置交给Spring

3、在struts.xml当配置action请求的跳转

4、创建Action类

package com.itzheng.ssh.web.action;import javax.servlet.ServletContext;import org.apache.struts2.ServletActionContext;import org.springframework.web.context.WebApplicationContext;import org.springframework.web.context.support.WebApplicationContextUtils;import com.itzheng.ssh.domain.Customer;import com.itzheng.ssh.service.CustomerService;import com.opensymphony.xwork2.ActionSupport;import com.opensymphony.xwork2.ModelDriven;/* * 客户管理的action的类 */public class CustomerAction extends ActionSupport implements ModelDriven
   
    {
   	//模型驱动使用的对象	private Customer customer = new Customer();	@Override	public Customer getModel() {
   		// TODO Auto-generated method stub		return customer;	}	/*	 * 注入CustomerService	 */	private CustomerService customerService;	public void setCustomerService(CustomerService customerService) {
   		this.customerService = customerService;	}	/*	 * 保存客户的方法：save	 */	public String save() {
   		System.out.println("Action当中的save方法执行类。。。。。");		customerService.save(customer);		return NONE;	}}
   

5、测试

三、Hibernate的模板的使用

1、在dao以及daoImpl当中设置几个Hibernate常用的方法

• 保存:save(Object obj);
• 更新:update(Object obj)
• 删除:delete(Oject obj)
• 查询:
  查询一个
  get(Class c,Serializable id);
  load(Class c,Serializable id);
  查询多个:
  List<?> find(String hql,Object... args);
  List<?> findByCriteria(DetachedCriteria dc);
  List<?> findByCriteria(DetachedCriteria dc,int firstResult,int maxResults);分页

package com.itzheng.ssh.dao;import java.util.List;import com.itzheng.ssh.domain.Customer;/* * 客户管理DAO层的接口 */public interface CustomerDao {
   	void save(Customer customer);		void update(Customer customer);	void delete(Customer customer);	Customer findById(Long cust_id);	List
   
     findAllByHQL();	List
    
      findAllByQBC();}
    
   

package com.itzheng.ssh.dao.impl;import java.util.List;import org.hibernate.criterion.DetachedCriteria;import org.springframework.orm.hibernate5.support.HibernateDaoSupport;import com.itzheng.ssh.dao.CustomerDao;import com.itzheng.ssh.domain.Customer;/* * 客户管理的DAO层的实现类 */public class CustomerDaoImpl extends HibernateDaoSupport implements CustomerDao {
   	@Override	public void save(Customer customer) {
   		// TODO Auto-generated method stub		System.out.println("Dao当中的save方法执行了");		// 保存customer对象		this.getHibernateTemplate().save(customer);	}	// 修改操作	@Override	public void update(Customer customer) {
   		// TODO Auto-generated method stub		this.getHibernateTemplate().update(customer);	}	@Override	public void delete(Customer customer) {
   		// TODO Auto-generated method stub		this.getHibernateTemplate().delete(customer);	}	@Override	public Customer findById(Long cust_id) {
   		// TODO Auto-generated method stub		return this.getHibernateTemplate().get(Customer.class, cust_id);	}	@Override	public List
   
     findAllByHQL() {
   		// TODO Auto-generated method stub		List
    
      find = (List
     
      ) this.getHibernateTemplate().find("from Customer");		return find;	}	@Override	public List
      
        findAllByQBC() {
   		// TODO Auto-generated method stub		DetachedCriteria criteria = DetachedCriteria.forClass(Customer.class);		List
       
         list = (List
        
         ) this.getHibernateTemplate().findByCriteria(criteria); return list; }}
        
       
      
     
    
   

2、在service以及serviceImpl当中调用dao的方法

package com.itzheng.ssh.service;import java.util.List;import com.itzheng.ssh.domain.Customer;/* * 客户管理的业务层的接口 */public interface CustomerService {
   	void save(Customer customer);	void update(Customer customer);	void delete(Customer customer);	void findById(Long cust_id);	List
   
     findAllByHQL();	List
    
      findAllByQBC();}
    
   

package com.itzheng.ssh.service.impl;import java.util.List;import org.springframework.transaction.annotation.Transactional;import com.itzheng.ssh.dao.CustomerDao;import com.itzheng.ssh.domain.Customer;import com.itzheng.ssh.service.CustomerService;@Transactionalpublic class CustomerServiceImpl implements CustomerService {
   	//注入DAO	private CustomerDao customerDao;	public void setCustomerDao(CustomerDao customerDao) {
   		this.customerDao = customerDao;	}	@Override	public void save(Customer customer) {
   		// TODO Auto-generated method stub		System.out.println("Service当中的save方法执行了。"+customer);		customerDao.save(customer);	}	@Override	public void update(Customer customer) {
   		// TODO Auto-generated method stub		customerDao.update(customer);	}	@Override	public void delete(Customer customer) {
   		// TODO Auto-generated method stub		customerDao.delete(customer);	}	@Override	public void findById(Long cust_id) {
   		// TODO Auto-generated method stub		customerDao.findById(cust_id);	}	@Override	public List
   
     findAllByHQL() {
   		// TODO Auto-generated method stub		return customerDao.findAllByHQL();	}	@Override	public List
    
      findAllByQBC() {
   		// TODO Auto-generated method stub		return customerDao.findAllByQBC();	}}
    
   

3、创建一个测试类

（1）修改

package com.itzheng.ssh.test;import javax.annotation.Resource;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import com.itzheng.ssh.domain.Customer;import com.itzheng.ssh.service.CustomerService;@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration("classpath:applicationContext.xml")public class SSHDemo1 {
   	@Resource(name = "customerService")	private CustomerService customerService;	public void setCustomerService(CustomerService customerService) {
   		this.customerService = customerService;	}	@Test	// 	public void demo1() {
   		Customer customer = customerService.findById(1l);		customer.setCust_name("赵一");				customerService.update(customer);		System.out.println(customer);	}}

（2）删除

（3）查询

（4）查询所有HQL

（5）查询所有QBC
