Struts2、Spring5、Hibernate整合
軟件：MyEclipse
一、創建Maven項目：
- new一個maven項目
- 將jdk換成1.8、web module換成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>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>

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

二、struts2、Spring5、hibernate配置：
src/main/resources:
- jdbc.properties(數據庫配置)文件：
jdbc.url=jdbc:mysql://localhost:3306/數據庫名?useSSL=true&characterEncoding=UTF-8
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.username=xxx
jdbc.password=xxx
- log4j.properties(打印日誌信息):
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
- spring.xml配置：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

三、Java類測試
src/main/java/com/lxf:
action包(controller層):
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-控制層
*
*/
@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", "商品名稱不能爲空");
}
}
}
dao包(model層):
CommodityDao接口：
package com.lxf.dao;
import com.lxf.model.Commodity;
/**
* 商品操作-持久層接口
*
*/
public interface CommodityDao {
void saveCommodity(Commodity commodity);
}
impl.CommodityDaoImpl實現類：
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-服務層實現
*
*/
@Repository
public class CommodityDaoImpl implements CommodityDao {
//Hibernate快捷操作模板，封裝部分底層。
//opensession，要自己開session，要自己關session
//開關全都是內部封裝的
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層):
Commodity實體類：
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") //自定義主鍵生成策略 generator = name
private int id;// 商品ID
@Column(length = 100)
private String name;// 商品名稱
@Column()
private double price;// 商品價格
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層):
CommodityService接口：
package com.lxf.service;
import com.lxf.model.Commodity;
/**
* 商品操作-服務層接口
*
*/
public interface CommodityService {
void saveCommodity(Commodity commodity);
}
impl.CommodityServiceImpl實現類：
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);
}
}
