1 整合步骤

1.1 手动创建web.xml

首先新建一个maven工程，在创建的webapp路径下新建一个WEB-INF文件夹，并在该文件夹下新建一个web.xml文件

1.2 添加依赖

在pom.xml中添加关于Struts2、Spring、Hibernate等完成的依赖，添加依赖时注意它的四个原则(https://blog.youkuaiyun.com/W2612888/article/details/86726664)

1.3 Hibernate文件的配置

2 示例

2.1 web层

package com.itykd.web.action;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;

import com.itykd.entity.Customer;
import com.itykd.service.CustomerService;
import com.opensymphony.xwork2.ActionSupport;

public class CustomerAction extends ActionSupport{
	
	@Resource(name="customerService")
	private CustomerService customerService;		
	private Customer customer;	
	private Long custId;

		public Customer getCustomer() {
			return customer;
		}
		public void setCustomer(Customer customer) {
			this.customer = customer;
		}
		
		public Long getCustId() {
			return custId;
		}
		public void setCustId(Long custId) {
			this.custId = custId;
		}
		public String findById(){
			customer = customerService.getById(custId);
			System.out.println("哈哈哈哈...");
			return SUCCESS;
		}
}

2.2 service层

package com.itykd.service.impl;

import javax.annotation.Resource;

import com.itykd.dao.CustomerDao;
import com.itykd.entity.Customer;
import com.itykd.service.CustomerService;

public class CustomerServiceImpl implements CustomerService{
	
	@Resource(name="customerDao")
	private CustomerDao customerDao;
	
	@Override
	public Customer getById(Long id) {
		
		return customerDao.getById(id);
	}

}

2.3 dao层

package com.itykd.dao.impl;

import org.springframework.orm.hibernate5.support.HibernateDaoSupport;

import com.itykd.dao.CustomerDao;
import com.itykd.entity.Customer;

public class CustomerDaoImpl extends HibernateDaoSupport implements CustomerDao{

	@Override
	public Customer getById(Long id) {
		return this.getHibernateTemplate().get(Customer.class, id);
	}

}
