篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Spring4.* 中整合 Hibernate相关的知识，希望对你有一定的参考价值。
1. Spring 整合 Hibernate 整合什么 ?
1). 有 IOC 容器来管理 Hibernate 的 SessionFactory
2). 让 Hibernate 使用上 Spring 的声明式事务
2. 整合步骤:
1). 加入 hibernate
①. jar 包
②. 添加 hibernate 的配置文件: hibernate.cfg.xml
③. 编写了持久化类对应的 .hbm.xml 文件。
2). 加入 Spring
①. jar 包
spring-aop-4.0.0.RELEASE.jar
spring-aspects-4.0.4.RELEASE.jar
spring-beans-4.0.0.RELEASE.jar
spring-context-4.0.0.RELEASE.jar
spring-core-4.0.0.RELEASE.jar
spring-expression-4.0.0.RELEASE.jar
commons-logging-1.2.jar
②. 加入 Spring 的配置文件
3). 整合.
3. 编写代码
整合工程目录结构如下图所示：
引用到的jar包如下：
spring的配置文件：applicationContext.xml

DAO层接口文件：BookShopDao
1 package com.lltse.spring.hibernate.dao; 2 3 public interface BookShopDao { 4 5 //根据书号获取书的单价 6 public int findBookPriceByIsbn(String isbn); 7 8 //更新数的库存. 使书号对应的库存 - 1 9 public void updateBookStock(String isbn); 10 11 //更新用户的账户余额: 使 username 的 balance - price 12 public void updateUserAccount(String username, int price); 13 }
DAO层接口实现类：
Entity:Account
1 package com.lltse.spring.hibernate.entities; 2 3 public class Account { 4 5 private Integer id; 6 private String username; 7 private int balance; 8 9 public Integer getId() { 10 return id; 11 } 12 13 public void setId(Integer id) { 14 this.id = id; 15 } 16 17 public String getUsername() { 18 return username; 19 } 20 21 public void setUsername(String username) { 22 this.username = username; 23 } 24 25 public int getBalance() { 26 return balance; 27 } 28 29 public void setBalance(int balance) { 30 this.balance = balance; 31 } 32 33 }
Book
1 package com.lltse.spring.hibernate.entities; 2 3 public class Book { 4 5 private Integer id; 6 private String bookName; 7 private String isbn; 8 private int price; 9 private int stock; 10 11 public Integer getId() { 12 return id; 13 } 14 15 public void setId(Integer id) { 16 this.id = id; 17 } 18 19 public String getBookName() { 20 return bookName; 21 } 22 23 public void setBookName(String bookName) { 24 this.bookName = bookName; 25 } 26 27 public String getIsbn() { 28 return isbn; 29 } 30 31 public void setIsbn(String isbn) { 32 this.isbn = isbn; 33 } 34 35 public int getPrice() { 36 return price; 37 } 38 39 public void setPrice(int price) { 40 this.price = price; 41 } 42 43 public int getStock() { 44 return stock; 45 } 46 47 public void setStock(int stock) { 48 this.stock = stock; 49 } 50 51 }
hibernate对实体的映射文件：
Account.hbm.xml
1 <?xml version="1.0"?> 2 <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" 3 "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> 4 5 <hibernate-mapping> 6 <class name="com.lltse.spring.hibernate.entities.Account" table="SH_ACCOUNT"> 7 8 <id name="id" type="java.lang.Integer"> 9 <column name="ID" /> 10 <generator class="native" /> 11 </id> 12 13 <property name="username" type="java.lang.String"> 14 <column name="USERNAME" /> 15 </property> 16 17 <property name="balance" type="int"> 18 <column name="BALANCE" /> 19 </property> 20 21 </class> 22 </hibernate-mapping>
Book.hbm.xml
1 <?xml version="1.0"?> 2 <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" 3 "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> 4 5 <hibernate-mapping> 6 <class name="com.lltse.spring.hibernate.entities.Book" table="SH_BOOK"> 7 8 <id name="id" type="java.lang.Integer"> 9 <column name="ID" /> 10 <generator class="native" /> 11 </id> 12 13 <property name="bookName" type="java.lang.String"> 14 <column name="BOOK_NAME" /> 15 </property> 16 17 <property name="isbn" type="java.lang.String"> 18 <column name="ISBN" /> 19 </property> 20 21 <property name="price" type="int"> 22 <column name="PRICE" /> 23 </property> 24 25 <property name="stock" type="int"> 26 <column name="STOCK" /> 27 </property> 28 29 </class> 30 </hibernate-mapping>
自定义异常：
