javaweb各种框架组合案例(三)：maven+spring+springMVC+hibernate
2024-10-02 03:14:39
1.hibernate译为“越冬”，指的是给java程序员带来春天，因为java程序员无需再关心各种sql了；
2.hibernate通过java类生成数据库表，通过操作对象来映射成SQL；
3.hibernate是真正意义上的ORM框架，因为他实现了对象（Object）---->关系（Relation）的映射（Mapping）；
4.maven项目整体包结构（报错是eclipse发神经，不用管）
因为hibernate可以根据类生成表，所以只需创建数据库即可;
create database ssh;
该案例实现了一个用户拥有多部手机的关系
5.各种配置文件

7.核心dao接口及其实现
package com.xiaog.core.dao;
import java.util.List;
public interface CoreDao<T> {
int insert(T t);
int delete(int id);
int update(T t);
T getOne(int id);
List<T> getList(T t);
}
CoreDao
package com.xiaog.core.dao.impl; import java.lang.reflect.ParameterizedType;
import java.util.List; import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.orm.hibernate4.support.HibernateDaoSupport; import com.xiaog.core.dao.CoreDao;
import com.xiaog.entity.User; //继承HibernateDaoSupport 可以直接使用CRUD操作
public class CoreDaoImpl<T> extends HibernateDaoSupport implements CoreDao<T> { private Class<T> clazz; private final static Logger logger = LoggerFactory.getLogger(CoreDaoImpl.class); @SuppressWarnings("unchecked")
public CoreDaoImpl() {
this.clazz = (Class<T>)((ParameterizedType) getClass().getGenericSuperclass()).getActualTypeArguments()[0];
} @Override
public int insert(T t) {
return (int) super.getHibernateTemplate().save(t);
} @Override
public int delete(int id) {
super.getHibernateTemplate().delete(new User() {{setId(id);}});
return 1;
} @Override
public int update(T t) {

} @Override
public List<T> getList(T t) {
//logger.info("进入CoreDaoImpl......");
return super.getHibernateTemplate().findByExample(t);
} }

import com.xiaog.dao.PhoneDao;
import com.xiaog.entity.Phone; @Repository
public class PhoneDaoImpl extends CoreDaoImpl<Phone> implements PhoneDao { }
PhoneDaoImpl
9.service接口及其实现
package com.xiaog.service;
import com.xiaog.entity.User;
public interface UserService {
User login(User user);
}
UserService
package com.xiaog.service.impl; import java.util.List; import org.slf4j.Logger;

public class UserServiceImpl implements UserService { @Autowired
private UserDao userDao; private final static Logger logger = LoggerFactory.getLogger(UserServiceImpl.class); @Override
public User login(User user) {
//logger.info("进入UserServiceImpl......");
List<User> users = userDao.getList(user);
logger.info("users="+users);
if(users!=null&&users.size()>0) {
return users.get(0);
}else {
return null;
}
} }
UserServiceImpl
10.controller
package com.xiaog.controller; import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;

14.注意点：我个人觉得ssh框架坑实在是多，我在搭建的过程中出现了各种各样的问题，不过最恶心的问题是spring和hibernate存在版本不兼容问题，一开始使用的是spring5+hibernate5，发现报错，就将hibernate5换成4（应该没问题了吧），结果还是报错，折腾半天，发现虽然Pom版本虽然换成4，但是之前dao层用到的HibernateDaoSupport和spring-context.xml配置中SessionFactory还是5的版本，诶，智障问题。
