Struts2、Spring5、Hibernate整合

软件：MyEclipse

一、创建Maven项目：

new一个maven项目
将jdk换成1.8、web module换成3.0
web.xml：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">

    <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>

    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>

  </listener>
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring.xml</param-value>
  </context-param>
</web-app>

二、struts2、Spring5、hibernate配置：

src/main/resources:

jdbc.properties(数据库配置)文件：

jdbc.url=jdbc:mysql://localhost:3306/数据库名?useSSL=true&characterEncoding=UTF-8
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.username=xxx
jdbc.password=xxx

log4j.properties(打印日志信息):

log4j.rootCategory=INFO, console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%d{yyyy-MM-dd HH\:mm\:ss} %5p %t %c{2}\:%L - %m%n

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

        </action>
    </package>

    <!-- 引入资源文件 -->
    <constant name="struts.custom.i18n.resources" value="messageResource"></constant>

</struts>

三、Java类测试

src/main/java/com/lxf:

action包(controller层):

package com.lxf.action;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;

import com.opensymphony.xwork2.ActionSupport;
import com.lxf.model.Commodity;
import com.lxf.service.CommodityService;

/**
 * 商品操作-控制层
 *
 */
@Controller
@Scope("prototype")
public class CommodityAction extends ActionSupport {

    private static final long serialVersionUID = 1L;
    @Autowired
    private CommodityService commodityService;
    private String pname;
    private double price;

    /**
     * 保存商品操作
     * 
     * @return
     */
    public String saveCommodity() {
        Commodity commodity = new Commodity(pname, price);
        commodityService.saveCommodity(commodity);
        this.addActionMessage("保存成功...");
        return SUCCESS;
    }

    public String getPname() {
        return pname;
    }

    public void setPname(String pname) {
        this.pname = pname;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;

    }

    @Override
    public void validate() {
        if(pname == null || "".equals(pname.trim())) {
            this.addFieldError("pname", "商品名称不能为空");
        }
    }

}

dao包(model层):

CommodityDao接口：

package com.lxf.dao;

import com.lxf.model.Commodity;

/**
 * 商品操作-持久层接口
 *
 */
public interface CommodityDao {
    void saveCommodity(Commodity commodity);
}

impl.CommodityDaoImpl实现类：

package com.lxf.dao.impl;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.orm.hibernate5.HibernateTemplate;
import org.springframework.stereotype.Repository;

import com.lxf.dao.CommodityDao;
import com.lxf.model.Commodity;



/**
 * 商品信息-服务层实现
 *
 */
@Repository
public class CommodityDaoImpl implements CommodityDao {

	//Hibernate快捷操作模板，封装部分底层。
	//opensession，要自己开session，要自己关session
	//开关全都是内部封装的
    private HibernateTemplate template;
    @Autowired
    public CommodityDaoImpl(SessionFactory sessionFactory) {
        this.template = new HibernateTemplate(sessionFactory);
    }
    
	@Override
	public void saveCommodity(Commodity commodity) {
		// TODO Auto-generated method stub
		template.save(commodity);
	}
    
}

model包(model层):

Commodity实体类：

package com.lxf.model;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;

import org.hibernate.annotations.GenericGenerator;

@Entity
@Table(name="commodity", catalog = "gc0910")
public class Commodity {

    @Id
    @GeneratedValue(generator = "id")
    @GenericGenerator(name = "id", strategy = "native") //自定义主键生成策略 generator = name
    private int id;// 商品ID
    @Column(length = 100)
    private String name;// 商品名称
    @Column()
    private double price;// 商品价格

    public Commodity() {
    }

    public Commodity(String name, double price) {
        this.name = name;
        this.price = price;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }
}

model包(model层):

CommodityService接口：

package com.lxf.service;

import com.lxf.model.Commodity;

/**
 * 商品操作-服务层接口
 *
 */
public interface CommodityService {
    void saveCommodity(Commodity commodity);
}

impl.CommodityServiceImpl实现类：

package com.lxf.service.impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.lxf.dao.CommodityDao;
import com.lxf.model.Commodity;
import com.lxf.service.CommodityService;

@Service
public class CommodityServiceImpl implements CommodityService {

    @Autowired
    private CommodityDao commodityDao;

	@Override
	public void saveCommodity(Commodity commodity) {
		commodityDao.saveCommodity(commodity);
	}

}
