1、创建动态web工程
（1）工程目录结构
（2）导入所需jar包
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：
<hibernate-mapping>
<class name="com.ming.ssh.domain.Customer" table="customer">
<id name="c_id">
<generator class="native">generator>
id>
<property name="c_name">property>
<property name="c_password">property>
<property name="c_address">property>
<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：
<context:component-scan base-package="com.ming.ssh">context:component-scan>
<context:property-placeholder location="classpath:jdbc.properties"/>
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${jdbc.driverClass}">property>
<property name="jdbcUrl" value="${jdbc.url}">property>

jdbc.properties：
jdbc.driverClass=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost/customer_manager?serverTimezone=UTC
jdbc.username=root
jdbc.password=1314
log4j.properties：

log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
log4j.rootLogger= info, stdout
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";
}
}
struts.xml：
<struts>
<constant name="struts.action.extension" value="action">constant>
<package name="ssh_customer_new" extends="struts-default" namespace="/">
<action name="customer_*" method="{1}" class="customerAction">

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：
