整合时建议一步步来,把每一个框架都做通,然后在处理整合的问题整合环境是struts2.2和hibernate4.2和spring4.2,jdk1.6
第一步:列举需要的jar包:
hibernate4.2jar包:
c3p0数据库jar包,当然也可以是使用spring提供的一个c3p0包:
数据库驱动,这里采用mysql数据库:mysql-connector-java-5.1.28-bin.jar
struts2jar包,注意有重复的jar,要删除,javassist,一般保留版本高的:
整合包spring和struts2:struts2-spring-plugin-2.3.28
做分布整合时,建议先不要导入,不然struts会无法起作用
spring4.2包:
aop联盟:
最后要注意的是如果使用注解开发,struts需要导入注解包:
第二步:各个层次的代码接口就不在写了:
po类:
public class User {
private Integer id;
private String name;
private Double money;
sett..
getter..
}hibernate映射文件:<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="com.leige.domain">
<class name="User" table="t_user">
<id name="id" type="int" column="id">
<generator class="native"></generator>
</id>
<property name="name" type="string" length="20" column="name"/>
<property name="money" type="double" column="money"/>
</class>
</hibernate-mapping>
dao层:
package com.leige.dao.impl;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.springframework.orm.hibernate4.HibernateTemplate;
import org.springframework.orm.hibernate4.support.HibernateDaoSupport;
import com.leige.dao.UserDao;
import com.leige.domain.User;
public class UserDaoImpl implements UserDao {
private HibernateTemplate hibernateTemplate;
public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
this.hibernateTemplate = hibernateTemplate;
}
public void addUser(User user) {
//保存对象
hibernateTemplate.save(user);
}
@Override
public void update(User user) {
this.hibernateTemplate.update(user);
}
@Override
public User findById(Integer id) {
// TODO Auto-generated method stub
return this.hibernateTemplate.get(User.class, id);
}
}
package com.leige.service.impl;
import javax.ejb.FinderException;
import com.leige.dao.UserDao;
import com.leige.dao.impl.UserDaoImpl;
import com.leige.domain.User;
import com.leige.service.UserService;
public class UserServiceImpl implements UserService {
UserDao userDao;
public void setUserDao(UserDao userDao) {
this.userDao = userDao;
}
/* 实现注册业务*/
@Override
public void regist(User form) {
userDao.addUser(form);
}
//实现转账业务
@Override
public void transfer(Integer from, Integer to, Double money) {
/*调用dao层实现转账业务:
*
*
* */
User fr=userDao.findById(from);
fr.setMoney(fr.getMoney()-money);
userDao.update(fr);
User tt=userDao.findById(to);
//int i=5/0;
tt.setMoney(tt.getMoney()+money);
userDao.update(tt);
}
}
package com.leige.web.action;
import com.leige.domain.User;
import com.leige.service.UserService;
import com.opensymphony.xwork2.ActionSupport;
public class UserAction extends ActionSupport{
/* service由spring注入*/
UserService userService;
public void setUserService(UserService userService) {
this.userService = userService;
}
private User user;
//转账业务所需参数
private Integer userTo;
private Integer userFrom;
private Double money;
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
public Integer getUserTo() {
return userTo;
}
public void setUserTo(Integer userTo) {
this.userTo = userTo;
}
public Integer getUserFrom() {
return userFrom;
}
public void setUserFrom(Integer userFrom) {
this.userFrom = userFrom;
}
public Double getMoney() {
return money;
}
public void setMoney(Double money) {
this.money = money;
}
public String add(){
userService.regist(user);
return "success";
}
public String pay(){
/*System.out.println("from----"+userFrom);
System.out.println("to----"+userTo);
System.out.println("money----"+money);*/
/* 调用service层实现转账*/
userService.transfer(userFrom, userTo, money);
return "success";
}
}
第三步各个层次的配置文件配置,详细解释都在配置文件中:
web.xml
