### 开发环境 ###

*  开发工具：Eclipse
 *  JDK版本：9.0.4
 *  MySQL版本：8.0.12
 *  服务器：Apache-Tomcat-9.0.12
 *  SSH版本：Spring-5.0.5.RELEASE + Struts-2.5.18 + Hibernate-5.2.12.Final

### 1、创建动态web工程 ###

####  （1）工程目录结构 ####

### 2、持久层实现 ###

#### customer\_manager数据库中customer表的构建： ####

#### Customer： ####

package com.ming.ssh.domain;
    import java.io.Serializable;
    /** * 定义实体类 * @author Mr.F * */
    public class Customer implements Serializable { 	
    	private static final long serialVersionUID = 1L;	
    	private Long c_id;
    	private String c_name;
    	private String c_password;
    	private String c_address;
    	private String c_phone;
    	private String c_email;	
    	public Long getC_id() { 
    		return c_id;
    	}
    	public void setC_id(Long c_id) { 
    		this.c_id = c_id;
    	}
    	public String getC_name() { 
    		return c_name;
    	}
    	public void setC_name(String c_name) { 
    		this.c_name = c_name;
    	}
    	public String getC_password() { 
    		return c_password;
    	}
    	public void setC_password(String c_password) { 
    		this.c_password = c_password;
    	}
    	public String getC_address() { 
    		return c_address;
    	}
    	public void setC_address(String c_address) { 
    		this.c_address = c_address;
    	}
    	public String getC_phone() { 
    		return c_phone;
    	}
    	public void setC_phone(String c_phone) { 
    		this.c_phone = c_phone;
    	}
    	public String getC_email() { 
    		return c_email;
    	}
    	public void setC_email(String c_email) { 
    		this.c_email = c_email;
    	}
    }

#### Customer.hbm.xml： ####

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
    
    <hibernate-mapping>
    	<class name="com.ming.ssh.domain.Customer" table="customer">
    		
    		<id name="c_id">

    		<property name="c_phone"></property>
    		<property name="c_email"></property>		
    	</class>
    </hibernate-mapping>

#### CustomerDao： ####

package com.ming.ssh.dao;
    import java.util.List;
    import com.ming.ssh.domain.Customer;
    /** * 定义持久层接口 * @author Mr.F * */
    public interface CustomerDao { 	
    	List<Customer> findAllCustomer(); //查询所有客户信息
    }

#### CustomerDaoImpl： ####

package com.ming.ssh.dao.impl;
    import java.util.List;
    import javax.annotation.Resource;
    import org.hibernate.SessionFactory;
    import org.hibernate.criterion.DetachedCriteria;
    import org.springframework.orm.hibernate5.support.HibernateDaoSupport;
    import org.springframework.stereotype.Repository;
    import com.ming.ssh.dao.CustomerDao;
    import com.ming.ssh.domain.Customer;
    /** * 实现持久层接口 * @author Mr.F * */
    @Repository("customerDao")
    public class CustomerDaoImpl extends HibernateDaoSupport implements CustomerDao{ 
    	@Resource(name="sessionFactory")
    	public void setSessionFactoryOverride(SessionFactory sessionFactory){ 	
    		super.setSessionFactory(sessionFactory);	
    	}
    	@SuppressWarnings("unchecked")
    	@Override
    	public List<Customer> findAllCustomer() { 		
    		DetachedCriteria criteria = DetachedCriteria.forClass(Customer.class);
    		List<Customer> list = (List<Customer>) this.getHibernateTemplate().findByCriteria(criteria);
    		return list;	
    	}
    }

### 3、业务层实现 ###

#### CustomerService： ####

package com.ming.ssh.service;
    import java.util.List;
    import com.ming.ssh.domain.Customer;
    /** * 定义业务层接口 * @author Mr.F * */
    public interface CustomerService { 
    	List<Customer> findAllCustomer(); //查询所有客户信息
    }

#### CustomerServiceImpl： ####

package com.ming.ssh.service.impl;
    import java.util.List;
    import javax.annotation.Resource;
    import org.springframework.stereotype.Service;
    import org.springframework.transaction.annotation.Propagation;
    import org.springframework.transaction.annotation.Transactional;
    import com.ming.ssh.dao.CustomerDao;
    import com.ming.ssh.domain.Customer;
    import com.ming.ssh.service.CustomerService;
    /** * 实现业务层接口 * @author Mr.F * */
    @Service("customerService")
    public class CustomerServiceImpl implements CustomerService{ 	
    	@Resource(name="customerDao")
    	private CustomerDao customerDao;	
    	@Transactional(propagation=Propagation.SUPPORTS, readOnly=true)
    	@Override
    	public List<Customer> findAllCustomer() { 
    		return customerDao.findAllCustomer();	
    	}
    }

#### applicationContext.xml： ####

### 4、控制层实现 ###

#### CustomerAction： ####

package com.ming.ssh.web;
    import java.util.List;
    import javax.annotation.Resource;
    import org.apache.struts2.ServletActionContext;
    import org.springframework.context.annotation.Scope;
    import org.springframework.stereotype.Controller;
    import com.ming.ssh.domain.Customer;
    import com.ming.ssh.service.CustomerService;
    import com.opensymphony.xwork2.ActionSupport;
    import com.opensymphony.xwork2.ModelDriven;
    /** * 定义控制层实现类 * @author Mr.F * */
    @Controller("customerAction")
    @Scope("prototype")
    public class CustomerAction extends ActionSupport implements ModelDriven<Customer>{ 
    	private static final long serialVersionUID = 1L;	
    	private Customer customer = new Customer();
    	@Override
    	public Customer getModel() { 	
    		return this.customer;		
    	}	
    	@Resource(name="customerService")
    	private CustomerService customerService;	
    	public String findAll() { 		
    		List<Customer> list = customerService.findAllCustomer();
    		ServletActionContext.getRequest().setAttribute("customerList", list);
    		return "findAllSuccess";	
    	}				
    }

### 5、工程测试 ###

将ssh\_customer\_new项目工程发布到本地tomcat服务器上，在浏览器地址栏访问http://localhost:8080/ssh\_customer\_new/customer\_findAll.action，其结果如下：
