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)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:

<?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">
<!--
定义实体类与数据库中表的映射
@author Mr.F
-->
<hibernate-mapping>
<class name="com.ming.ssh.domain.Customer" table="customer">
<!-- 当实体类的属性名与表中的字段名相同时,可省略column -->
<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:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

jdbc.properties:

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

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:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC

</package>
</struts>

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:
