spring mvc+hibernate 实现事务管理（全注解版）

文章标签 java 实现 spring 注解 事务管理 mvc hibernate

本文主要是介绍spring mvc+hibernate 实现事务管理（全注解版），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

为了方便项目变大配置文件变多，用注解代替 *.hbm.xml,<bean id="*dao" class="">,另外用反省实现dao操作，省去每个类一个dao，此处参考了鸵鸟的例子。

实现功能跟http://blog.csdn.net/waiwai4701/article/details/38270721这个项目是一样的，controller和页面就不再写

首先，jar包支持，为了方便jar包管理采用maven技术，服务器没有用tomcat用的jetty，不要在意这些细节

实体类： 
package Sand.mas.model;import java.io.Serializable;import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;@Entity
@Table(name = "tuser")
public class User implements Serializable {private static final long serialVersionUID = 1L;private String id;private String userName;private String password;public User(){}public User(String userName,String password){this.userName = userName;this.password = password;}@Id@GeneratedValue(strategy = GenerationType.IDENTITY)@Column(name = "id", unique = true, nullable = false)public String getId() {return id;}public void setId(String id) {this.id = id;}@Column(name = "username", length = 20)public String getUserName() {return userName;}public void setUserName(String userName) {this.userName = userName;}@Column(name = "password", length = 20)public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}public String toString(){return "user:id="+id+",userName="+userName+",password="+password;}}
一些基础用于扩展的东西：

BaseDao

package Sand.mas.sys;import java.io.Serializable;
import java.util.List;public interface BaseDao<T> {/*** 保存一个对象* * @param o* @return*/public Serializable save(T o);/*** 删除一个对象* * @param o*/public void delete(T o);/*** 更新一个对象* * @param o*/public void update(T o);/*** 保存或更新对象* * @param o*/public void saveOrUpdate(T o);/*** 查询* * @param hql* @return*/public List<T> find(String hql);/*** 查询集合* * @param hql* @param param* @return*/public List<T> find(String hql, Object[] param);/*** 查询集合* * @param hql* @param param* @return*/public List<T> find(String hql, List<Object> param);/*** 查询集合(带分页)* * @param hql* @param param* @param page*            查询第几页* @param rows*            每页显示几条记录* @return*/public List<T> find(String hql, Object[] param, Integer page, Integer rows);/*** 查询集合(带分页)* * @param hql* @param param* @param page* @param rows* @return*/public List<T> find(String hql, List<Object> param, Integer page, Integer rows);/*** 获得一个对象* * @param c*            对象类型* @param id* @return Object*/public T get(Class<T> c, Serializable id);/*** 获得一个对象* * @param hql* @param param* @return Object*/public T get(String hql, Object[] param);/*** 获得一个对象* * @param hql* @param param* @return*/public T get(String hql, List<Object> param);/*** select count(*) from 类* * @param hql* @return*/public Long count(String hql);/*** select count(*) from 类* * @param hql* @param param* @return*/public Long count(String hql, Object[] param);/*** select count(*) from 类* * @param hql* @param param* @return*/public Long count(String hql, List<Object> param);/*** 执行HQL语句* * @param hql* @return 响应数目*/public Integer executeHql(String hql);/*** 执行HQL语句* * @param hql* @param param* @return 响应数目*/public Integer executeHql(String hql, Object[] param);/*** 执行HQL语句* * @param hql* @param param* @return*/public Integer executeHql(String hql, List<Object> param);}
BaseDao实现类BaseDaoImpl 
package Sand.mas.sys;import java.io.Serializable;
import java.util.List;import org.hibernate.Query;
import org.hibernate.Session;
import org.springframework.beans.factory.annotation.Autowired;

BaseService: 

package Sand.mas.sys;public interface BaseService {
//也就是直接性的什么都没有，只为了实现类节省每个扩展service的@transaction
}

实现类 BaseServiceImpl: 
package Sand.mas.sys;import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;@Service("baseService")
@Transactional(readOnly = false,propagation = Propagation.REQUIRED,rollbackFor = Exception.class)
public class BaseServiceImpl implements BaseService{}
UserService: 
package Sand.mas.service;public interface UserService {public void test();
}

UserServiceImpl: 

package Sand.mas.service.impl;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;import Sand.mas.model.User;
import Sand.mas.service.UserService;
import Sand.mas.sys.BaseDao;
import Sand.mas.sys.BaseServiceImpl;@Service("userService")
public class UserServiceImpl extends BaseServiceImpl implements UserService{private BaseDao<User> userDao;//看到妙处没public BaseDao<User> getUserDao() {return userDao;}@Autowiredpublic void setUserDao(BaseDao<User> userDao) {this.userDao = userDao;}@Transactional(rollbackFor=Exception.class)public void test() {User user1 = new User("zhangsan","111111");User user2 = new User("lisi","222222222222222222222222222222");userDao.save(user1);System.out.println("user1 success");userDao.save(user2);System.out.println("user2 success");}}
最后，配置文件，折腾了姐好久
