首先需要在Maven中导入如下的依赖：

<?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
        <modelVersion>4.0.0</modelVersion>
    
        <groupId>com.lsj</groupId>
        <artifactId>SpringStudyHibernate</artifactId>
        <version>1.0-SNAPSHOT</version>
        <dependencies>
            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-context</artifactId>
                <version>4.3.7.RELEASE</version>
            </dependency>
            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-jdbc</artifactId>
                <version>4.3.7.RELEASE</version>
            </dependency>
            
            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-orm</artifactId>
                <version>4.3.7.RELEASE</version>
            </dependency>
            <dependency>
                <groupId>org.aspectj</groupId>
                <artifactId>aspectjweaver</artifactId>
                <version>1.8.10</version>
            </dependency>
    
            
            <dependency>
                <groupId>mysql</groupId>
                <artifactId>mysql-connector-java</artifactId>
                <version>5.1.38</version>
            </dependency>
            
            <dependency>
                <groupId>c3p0</groupId>
                <artifactId>c3p0</artifactId>
                <version>0.9.1.2</version>
            </dependency>
    
            <dependency>
                <groupId>junit</groupId>
                <artifactId>junit</artifactId>
                <version>RELEASE</version>
            </dependency>
    
            
            <dependency>
                <groupId>org.hibernate</groupId>
                <artifactId>hibernate-core</artifactId>
                <version>4.3.11.Final</version>
            </dependency>
    
    
        </dependencies>
    
    
    
    </project>

随后需要在配置文件中添加如下的代码:

1.导入数据库的配置文件:

<context:property-placeholder location="classpath:db.properties"/>

2.配置c3p0:

<bean id="datasource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
            <property name="user" value="${jdbc.user}" ></property>
            <property name="password" value="${jdbc.password}" ></property>
            <property name="jdbcUrl" value="${jdbc.jdbcUrl}" ></property>
            <property name="driverClass" value="${jdbc.driverClass}" ></property>
            <property name="initialPoolSize" value="${jdbc.initPoolSize}" ></property>
            <property name="maxPoolSize" value="${jdbc.maxPoolSize}" ></property>
        </bean>

3.配置Hibernate的sessionFactory实例：

<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
                
                <property name="dataSource" ref="datasource"></property>
                
                
                
                
                <property name="hibernateProperties">
                    <props>
                        <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop>
                        <prop key="hibernate.show_sql">true</prop>
                        <prop key="hibernate.format_sql">true</prop>
                        <prop key="hibernate.hbm2ddl.auto">update</prop>
                    </props>
                </property>
                
                <property name="mappingLocations"
                          value="classpath:com/sh/entities/*.hbm.xml">
                </property>
            </bean>

4.配置spring的申明式事务

5.配置事务切点:

<aop:config>
           <aop:pointcut id="txPointcut" expression="execution(* com.sh.service.*.*(..))" />
           <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointcut"/>
    </aop:config>

以上就是Spring整合hibernate的配置

Spring整合hibernate的原因:

主要是:

a、让spring提供的IOC容器来管理hibernate的SessionFactory

b、让Hibernate使用Spring提供的声明式事物
